Un-beet-able: Study shows beetroot can boost athletic performance

Un-beet-able: Study shows beetroot can boost athletic performance

( Natural News ) Beets are often used to make a sour soup called borscht or salads, but the root vegetable might soon be consumed by many athletes. According to a study conducted by researchers from the University of South Australia (UniSA), beets can naturally boost athletic performance .

Researchers conducted a meta-analysis of 118 studies from 25 countries and they assessed the performance effects of several foods considered to benefit aerobic performance. Results showed that beetroot , grapes, sour cherries and pine bark extract helped boost endurance exercise performance by improving nitric oxide availability in the body.

Beetroot’s high nitrate levels, which have been shown to improve blood circulation and increase oxygen and nutrient delivery to muscles during exercise, helped the athletes reach peak performance quicker. On the other hand, the polyphenols in cherries , grapes, and pine bark extract protected nitrate from degradation, which helped increase stamina.

Polyphenols are powerful antioxidants that can help reduce the impact of oxidative stress. These compounds also prevent or reverse cell damage caused by aging, environmental and lifestyle factors.

Noah D’Unienville, the study’s lead researcher, said the study findings prove that beets and certain foods are “natural endurance enhancers.”

A low-calorie vegetable, beets are full of essential vitamins and minerals .

Beets contain a bit of almost all of the vitamins and minerals your body needs to stay healthy. A 3.5-ounce (100-gram) serving of boiled beetroot contains 44 calories, 0.2 grams of fat, two grams of fiber, 1.7 grams of protein and 10 grams of carbs. The same serving also contains: Folate – 20 percent of the Daily Value (DV)

Manganese – 14 percent of the DV

Copper – eight percent of the DV

Potassium – seven percent of the DV

Magnesium – six percent of the DV

Iron – four percent of the DV

Vitamin B6 – four percent of the DV

Vitamin C – four percent of the DV

Beets are a great source of folate, a vitamin that has an important role in growth, development and heart health. Additionally, beets are rich in manganese, a nutrient with a role in bodily functions like bone formation, nutrient metabolism and brain function.

Beets are also full of copper, an essential mineral needed for energy production and the synthesis of certain neurotransmitters. Beets contain compounds with protective effects

D’Unienville explained that while there is a lot of interest in nitrate-rich and polyphenol-rich foods due to their potential to boost exercise performance, it doesn’t mean that containing these elements will automatically translate into an improvement in exercise performance.

For example, the UniSA study showed that beetroot can boost performance but other foods full of nitrates, like red spinach, rhubarb and Swiss chard did not offer similar benefits. At the same time, while grapes, sour cherries and pine bark extract helped boost the athletes’ performance, other foods full of polyphenols like blackcurrant, cocoa, ginseng and green tea did not.

There isn’t a lot of data on spinach, Swiss chard and rhubarb compared to beetroot, but D’Unienville said it’s possible those three vegetables did not show performance benefits even though they were full of nitrates because they are also lower in polyphenols than beetroot. (Related: Beetroot is packed with disease-fighting antioxidants, phytonutrients and essential nutrients .)

The protective effect of these antioxidants on the nitric oxide converted from the nitrate in the beetroot may make the difference, said D’Unienville. He added that in some studies where nitrates were removed from the beetroot, the vegetable still had a minor effect on exercise performance.

Jon Buckley, a study co-researcher, said that despite the benefits of foods like beetroot, grapes and sour cherries to exercise performance, their effects did discriminate. More significant effects were observed in the athletes who were less fit. Men were also more likely to benefit from beetroot, grapes and sour cherries than women.

If you want to boost your athletic performance, Buckley recommends training regularly and consuming beetroot juice.

LOCKDOWN LUNACY: Social isolation harms brain health and increases dementia risk, warn researchers

LOCKDOWN LUNACY: Social isolation harms brain health and increases dementia risk, warn researchers

( Natural News ) During the Wuhan coronavirus (COVID-19) pandemic, governments across the globe enforced many draconian measures like lockdowns and vaccine passports to curb the spread of coronavirus. However, studies show that lockdowns may have done more harm than good, especially to the mental health of people of all ages who have had to spend time in social isolation.

Social isolation, or “the absence or near absence of social connections or relationships,” and loneliness are bad for your well-being. Research points to a connection between living in social isolation and health problems like anxiety, depression, decreased immunity and various physical stress responses.

According to a study published in the journal Neurology , social isolation can even harm the brain and increase dementia risk . People who are socially isolated have a greater risk of developing “later dementia”

For the study, researchers used data gathered from 30,000 participants at the U.K. Biobank .

After examining the data, they discovered that people who were socially isolated had a 26 percent greater probability of developing dementia than socially active individuals. People older than 60 are the hardest hit.

Social isolation itself is a risk factor for dementia and negatively affects brain health.

Barbara J. Sahakian, a professor at the University of Cambridge Department of Psychiatry, advised that since social isolation is a risk to brain health and is linked to dementia, the government and communities must take immediate action “to ensure that older individuals have communication and interactions with others on a regular basis.” The results of a 2021 study also concluded that the forced social isolation that affected many individuals during the pandemic caused a domino effect of repercussions regarding mental health. Scientists examined patients and their caregivers, along with the impact of social isolation and found that: Over 50 percent of patients with dementia experienced a decline in memory function.

Over 30 percent of the patients felt sadder.

At least 40 percent experienced an increase in their anxiety symptoms.

The increase in anxiety symptoms caused an increase in dementia symptoms , such as agitation, hallucinations and difficulty in daily life activities. CDC pushed lockdowns despite their known health risks

The Centers for Disease Control and Prevention (CDC) referenced several studies that highlight the health risks linked to social isolation in adults older than 50.

Studies revealed that social isolation can increase the risk of: Anxiety, depression and suicide

Stroke by 32 percent

Dementia by about 50 percent

Heart disease by 29 percent

Premature death from all causes

Heart failure patients who were socially isolated had: A four-fold increase in the risk of death

Increased risk of hospitalization by 68 percent

Increased risk of emergency room visits by 57 percent

Despite these dangers, during the coronavirus pandemic the CDC advised people to quarantine and isolate themselves . Tips for reducing dementia risk

Here are some tips that can help reduce your risk of dementia :

Monitor your blood pressure and keep systolic blood pressure at 130 mm Hg or lower, especially if you are 40 or older.

Reduce exposure to secondhand smoke and air pollution.

Be careful and prevent falls to avoid head injury . Make sure your home is fall-proof and wear shoes with non-skid soles that fully support your feet. Join fall prevention programs online or in your city. When riding in a car, always wear seatbelts and helmets to help protect you from concussions and other brain injuries.

Maintain good physical health and a healthy weight. Being overweight or obese may increase your risk of related health problems like diabetes and heart disease.

Eat a nutritious diet consisting of different organic fruits and vegetables, whole grains, lean meats and seafood, unsaturated fats like olive oil and low-fat or nonfat dairy products. Limit your intake of other fats and sugars. (Related: Study: Choline helps improve cognitive performance in the elderly .) Limit or avoid alcohol consumption altogether. Drinking too much alcohol can cause falls and worsen health conditions like diabetes, high blood pressure, memory loss, mood disorders and stroke. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), men should only have two drinks a day and women only one. Don’t smoke or quit smoking. Whether you’re young or old, quitting smoking can improve your health and lower your risk of heart attack, lung disease and stroke. Keep your brain active with brain games, puzzles, lessons and discussions. You can also read more books, start a new craft or take up a new hobby. Another option is to work or volunteer. Keeping your sugar intake very low . Higher than normal levels of blood sugar (glucose) can cause diabetes and may increase your risk of cognitive impairment, dementia, heart disease and stroke. Improve your eating habits, exercise regularly, quit smoking and monitor your glucose levels to manage your blood sugar. Get at least seven to eight hours of good quality sleep . Restful sleep is important for both your mind and body. Talk to your doctor if you are not getting enough sleep or having trouble sleeping. Have regular social interaction with your family and friends . Connecting with people and engaging in social activities can help prevent social isolation and loneliness, which are linked to higher risks for cognitive decline and Alzheimer’s.If you are caring for an older family member, senior centers or senior daycare facilities can be a good way to help them get some social interaction. Plan ahead for older adults who may suffer greatly from loneliness and isolation so you’re ready for another pandemic.Regardless of age, people are social creatures. It’s important to interact with others.Visit BrainHealthBoost.com for more tips on how to boost brain health and prevent dementia.Watch the video below to find out how magnesium can boost your brain health .

Healthy human brains are hotter than previously thought, research finds

New research has shown that normal human brain temperature varies much more than we thought, and this could be a sign of healthy brain function. In healthy men and women, where oral temperature is typically less than 37°C, average brain temperature is 38.5°C, with deeper brain regions often exceeding 40°C, particularly in women during the daytime.

Previously, human brain temperature studies have relied upon data capture from brain-injured patients in intensive care, where direct brain monitoring is often needed. More recently, a brain scanning technique, called magnetic resonance spectroscopy (MRS), has enabled researchers to measure brain temperature non-invasively in healthy people. Until now, however, MRS had not been used to explore how brain temperature varies throughout the day, or to consider how an individual’s ‘body clock’ influences this.

The new study, led by researchers at the Medical Research Council (MRC) Laboratory for Molecular Biology, in Cambridge, UK, has produced the first 4D map of healthy human brain temperature. This map overturns several previous assumptions and shows the remarkable extent to which brain temperature varies by brain region, age, sex, and time of day. Importantly, these findings also challenge a widely held belief that human brain and body temperature are the same.

The research, published in the journal Brain , also included analysis of data from patients with traumatic brain injury, showing that the presence of daily brain temperature cycles strongly correlates with survival. These findings could be used to improve understanding, prognosis, and treatment of brain injury.

Striking brain temperature variation in health

To study the healthy brain, the researchers recruited 40 volunteers, aged 20-40 years, to be scanned in the morning, afternoon, and late evening over one day, at the Edinburgh Imaging Facility, Royal Infirmary of Edinburgh.

Crucially, they also gave the participants a wrist-worn activity monitor, allowing genetic and lifestyle differences in the timing of each person’s body clock, or circadian rhythm, to be taken into account. For both ‘night owls’ or ‘morning larks’, knowing the biological time-of-day that each brain temperature measurement was taken at allowed differences between each volunteer’s body clock to be factored into the analysis.

In healthy participants, the average brain temperature was 38.5°C, more than two degrees warmer than that measured under the tongue. The study also found that brain temperature varied depending on: time of day,

brain region,

sex and menstrual cycle,

and age.

While the brain surface was generally cooler, deeper brain structures were frequently warmer than 40°C; with the highest observed brain temperature being 40.9°C. Across all individuals, brain temperature showed consistent time-of-day variation by nearly 1°C, with highest brain temperatures observed in the afternoon, and the lowest at night.

On average, female brains were around 0.4°C warmer than male brains. This sex difference was most likely driven by the menstrual cycle, since most females were scanned in the post-ovulation phase of their cycle, and their brain temperature was around 0.4°C warmer than that of females scanned in their pre-ovulation phase.

The results also showed that brain temperature increased with age over the 20-year range of the participants, most notably in deep brain regions, where the average increase was 0.6°C. The researchers propose that the brain’s capacity to cool down may deteriorate with age and further work is needed to investigate whether there is linked with the development of age-related brain disorders.

Dr John O’Neill, Group Leader at the MRC Laboratory for Molecular Biology, said:

“To me, the most surprising finding from our study is that the healthy human brain can reach temperatures that would be diagnosed as fever anywhere else in the body. Such high temperatures have been measured in people with brain injuries in the past, but had been assumed to result from the injury.”

“We found that brain temperature drops at night before you go to sleep and rises during the day. There is good reason to believe this daily variation is associated with long-term brain health — something we hope to investigate next.”

Temperature rhythms in injured brains

To explore the clinical implications of data obtained from healthy volunteers, the researchers analysed temperature data collected continuously from the brain in 114 patients who had suffered from moderate to severe traumatic brain injury (TBI). The patients’ average brain temperature was 38.5°C, but it varied even more widely, from 32.6 to 42.3°C.

Of 100 patients for whom there was enough data to test for daily rhythms, only a quarter had a daily rhythm in brain temperature. Focusing on predictors of survival in intensive care, the researchers found that absolute brain temperature measurements were of limited use, but daily brain temperature variation was strongly linked with survival — indeed, of TBI patients with a daily brain temperature rhythm only 4% died in intensive care, versus 27% who had no such rhythm.

The researchers caution that larger studies are needed to validate this association, and that the link between brain temperature and survival is correlative only, meaning that daily brain temperature rhythms cannot be assumed to directly increase survival. However, the observed link means that monitoring daily brain temperature cycles in TBI patients might be a promising tool to predict survival and would benefit from further research.

Together with the data from healthy people, the findings of this work raise important questions about the use of interventions to modify or control patient temperature in the clinic.

Dr Nina Rzechorzek, MRC Clinician Scientist Fellow from the MRC Laboratory for Molecular Biology who led the study, said:

“Using the most comprehensive exploration to date of normal human brain temperature, we’ve established ‘ HEATWAVE ‘ — a 4D temperature map of the brain. This map provides an urgently-needed reference resource against which patient data can be compared, and could transform our understanding of how the brain works. That a daily brain temperature rhythm correlates so strongly with survival after TBI suggests that round-the-clock brain temperature measurement holds great clinical value.”

“Our work also opens a door for future research into whether disruption of daily brain temperature rhythms can be used as an early biomarker for several chronic brain disorders, including dementia.”

Consumption of citrus fruits linked to lower stroke risk

Consumption of citrus fruits linked to lower stroke risk

( Natural News ) Citrus fruits are known for being full of vitamin C and having immune system-boosting properties. According to a study, regular consumption of nutritious citrus fruits may also help reduce stroke risk .

The study was conducted by researchers from the University of East Anglia (UEA) in Norwich, United Kingdom. The study findings showed that eating citrus fruit, especially oranges, “lowers the risk of ischemic stroke significantly.”

For the study, the research team compared the health of adult female volunteers who ate both oranges and grapefruit regularly versus those who did not. The researchers also analyzed the flavonoid content of citrus fruits and how they affected blood vessel health.

Data from earlier studies have revealed that specific orange phytochemicals had protective benefits against intracerebral hemorrhage and significantly improved blood flow in the brain.

In the UEA study, researchers reviewed around 14 years of the Nurse’s Health Study data tracking the health and diets of at least 70,000 women. They assessed correlations between six flavonoid sub-classes from citrus fruits related to risks of hemorrhagic, ischemic or complete stroke .

Based on the findings, the female volunteers who consumed the highest amounts of orange and grapefruit along with juices from these fruits had much better blood circulation. The women also had a 19 percent lowered risk of stroke related to blood clotting compared with the women who didn’t consume as much citrus fruits. Citrus consumption and reduced stroke risk

The women who ate more citrus fruits showed a substantially reduced risk of stroke and associated risks, reported the researchers. Other studies of flavonoids in fruits support these results about a reduction in stroke risk. Data suggest that a higher intake of all kinds of fruit has a positive impact on stroke risk and other areas of health.

For example, a 2011 study conducted by researchers from Western University in London, Ontario, revealed that flavonoid intake also helped prevent weight gain.

The study found that nobiletin, a tangerine flavonoid, helped reduce the risk of both Type 2 diabetes and obesity in mice. The mice given the nobiletin flavonoid didn’t develop these health problems while the mice that did not become obese developed Type 2 diabetes and had atherosclerosis and fatty liver issues. Other health benefits of citrus fruits

According to a 2012 Japanese study, the pulp and juice from satsuma mandarin oranges inhibited tumor growth in colon, lung and tongue cancers.

This is important because vitamin C is a potent antioxidant that can help inhibit free radical damage in the cells. The nobiletin in citrus fruit has also been linked with apoptosis or the programmed cell death of cancer cells.

In another study, scientists from Oregon Health & Science University discovered that there is a link between eye health and the vitamin C found in citrus fruits. According to their data, retinal nerve cells benefited from the compound.

The research team believes that there is a chance that both brain and nervous system health are also positively impacted by vitamin C.

While natural fruit juice is nutritious, consuming whole oranges, grapefruits and other fruits offer amazing health benefits. Whole fruits usually contain more vitamins and nutrients and are lower in sugar and higher in dietary fiber. Follow a balanced diet to prevent stroke

Making small changes to your eating habits can have a significant difference in your overall health, especially if you are at risk of having a stroke or transient ischemic attack (TIA).

A transient ischemic attack is a stroke that lasts for only several minutes. It happens when the blood supply to part of your brain is briefly blocked .

Symptoms of a TIA are like other stroke symptoms, but it doesn’t last as long. They happen suddenly and may include: Confusion and trouble speaking or understanding speech

Difficulty walking

Dizziness

Loss of balance or coordination

Numbness or weakness, especially on one side of the body

Trouble seeing in one or both eyes

Eating a healthy, balanced diet will also help lower your blood pressure and control diabetes.

Cholesterol is a fatty substance produced in your body. You can also absorb cholesterol from fatty foods.

If there’s too much cholesterol in your blood, it can cause fatty deposits to build up in your arteries and restrict blood flow. Fortunately, improving your eating habits can help reduce your cholesterol level.

Compounds in ginger and chili peppers found to prevent cancer

Compounds in ginger and chili peppers found to prevent cancer

( Natural News ) On their own, both ginger and chili are delicious spices with well-known health benefits.

Ginger is used in traditional medicine to relieve common health complaints like digestive issues and nausea. On the other hand, chili peppers help boost your mood, metabolism and immune system.

Both ginger and chili peppers can also improve blood circulation.

According to an animal study, combining certain compounds from both ginger and chili pepper can help prevent cancer . Researchers discovered that the likelihood of developing lung cancer was significantly reduced when animal subjects were given these compounds together.

The study was published in the Journal of Agricultural and Food Chemistry . Preventing tumor growth with ginger and chili pepper compounds

Study findings showed that 6-gingerol in ginger and capsaicin, a chili pepper compound, work well together to effectively prevent cancer .

This is because 6-gingerol binds to capsaicin to create a new, extremely strong compound that can help inhibit tumor-growing cell receptors in the body.

For the study, researchers fed mice prone to lung cancer either 6-gingerol or capsaicin alone or in combination for several weeks. All of the mice given only the capsaicin developed tumors in their lungs while only half of the 6-gingerol-only mice did.

Meanwhile, only 20 percent of the mice that received the combination of both capsaicin and 6-gingerol developed cancer.

The study shows that when it comes to fighting cancer, combining 6-gingerol and capsaicin is more effective than taking only ginger or chili pepper. Combining the two forms a powerful compound that binds to cell receptors that would otherwise trigger tumor growth. Health benefits of ginger and chili pepper

It’s amazing that combining two already beneficial spices like ginger and chili pepper can help prevent cancer .

When cooking at home, you can give dishes a nutritious flavor boost by using either fresh or dried ginger and chili peppers.

But that’s not all. Detailed below are more health benefits of ginger and chili pepper. Ginger health benefits

In traditional and alternative medicine, ginger is used to aid digestion , reduce nausea and help fight the flu and common cold.

Ginger’s unique fragrance and flavor are due to its natural oils, the most important of which is gingerol. As the main bioactive compound in ginger, gingerol is responsible for many of ginger’s medicinal properties.

Data suggest that gingerol has potent anti-inflammatory and antioxidant effects. It can help reduce oxidative stress, which is often caused by having an excess amount of free radicals in the body.

Ginger helps treat many forms of nausea

The data have proven that ginger is very effective against nausea.

Ginger can help ease nausea and vomiting in people undergoing certain types of surgery. It may also help with chemotherapy-related nausea.

According to research, ginger is most effective when treating pregnancy-related nausea, such as morning sickness. According to a review of 12 studies that included a total of 1,278 pregnant women, taking 1.1 to 1.5 grams of ginger can significantly reduce symptoms of nausea.

While ginger is considered safe to consume, consult your doctor before taking large amounts of ginger when pregnant. Take note that pregnant women who are close to labor or who have had miscarriages should avoid ginger since it is contraindicated with a history of vaginal bleeding and clotting disorders.

Ginger helps promote weight loss

Data from studies conducted on both humans and animals suggest that ginger can help promote weight loss.

In a 2016 study involving 80 women with obesity, findings showed that ginger could help reduce body mass index (BMI) and blood insulin levels. High blood insulin levels are often linked to obesity. The volunteers were given relatively high daily doses of two grams of ginger powder for 12 weeks.

According to a 2019 literature review, ginger supplementation can significantly reduce body weight, the waist-hip ratio and the hip ratio of overweight or obese individuals.

In a 2019 literature review of functional foods, researchers reported that ginger had a very positive effect on obesity and weight loss.The evidence supporting ginger’s role in helping prevent obesity is stronger in animal studies.According to one study, rats and mice given ginger water or ginger extract consistently saw decreases in their body weight, even when they were also fed high-fat diets.Experts believe that ginger’s ability to influence weight loss may be related to certain mechanisms, like its potential to help increase the number of calories burned or reduce inflammation. Ginger helps with osteoarthritis Osteoarthritis is a common health problem that involves degeneration of the joints in the body. It can result in debilitating symptoms like joint pain and stiffness.According to a literature review, individuals who used ginger to treat their osteoarthritis saw significant reductions in pain and disability. Mild side effects, like dissatisfaction with the taste of ginger, were reported.The volunteers received between 500 milligrams (mg) and one gram of ginger each day between three to 12 weeks. A majority of the volunteers had been diagnosed with osteoarthritis of the knee.Another 2011 study revealed that a combination of topical ginger, mastic, cinnamon and sesame oil can help reduce pain and stiffness in people with osteoarthritis of the knee. Ginger helps improve brain function and prevent Alzheimer’s disease Oxidative stress and chronic inflammation can accelerate the aging process. These two factors are also believed to be among the key drivers of Alzheimer’s disease and age-related cognitive decline.Data from some animal studies suggest that the antioxidants and bioactive compounds in ginger can help curb inflammatory responses that occur in the brain.Research also suggests that ginger can help enhance brain function directly. According to a 2012 study of healthy middle-aged women, taking ginger extract daily can help improve reaction time and working memory.Additionally, several animal studies have found that ginger can help fight age-related decline in brain function. Chili pepper health benefits Chili peppers have a burning taste, but consuming this fiery spice also offers several health benefits. Chili peppers are full of vitamins and minerals such as: Copper – Copper is an essential trace element. You need copper for strong bones and healthy neurons. Potassium – Potassium is an […]

Regular olive oil consumption found to reduce mortality risk

Regular olive oil consumption found to reduce mortality risk

( Natural News ) Olive oil is a popular cooking oil because it contains antioxidants and healthy fats. According to a study conducted by researchers from the American College of Cardiology , consuming olive oil regularly is also linked to a lower risk of some severe medical conditions , such as heart disease and cancer.

The study was published in the Journal of the American College of Cardiology .

During the study, the research team found that respiratory disease mortality and neurodegenerative disease mortality are also less common in individuals who consume over seven grams of olive oil per day.

Additionally, replacing 10 grams of butter, mayonnaise and dairy fat daily with the same quantity of olive oil helped significantly reduce mortality risk .

Dr. Marta Guasch-Ferre, the study’s first author, said the results support current dietary recommendations to “increase the intake of olive oil and other unsaturated vegetable oils.”

She added that clinicians should advise patients to replace certain fats, like butter and margarine , with olive oil to improve their well-being. The study findings can be used to make more specific recommendations that will be easier for patients to understand and implement into their regular diets. (Related: Study links olive oil intake to reduced heart disease and Alzheimer’s risk .) Olive oil consumption and lower disease risk

For the study, the scientists analyzed the diets of more than 30,000 men and over 60,000 women. All the volunteers were disease-free when the trial began in 1990. The volunteers filled in surveys every four years to track their average fat and oil consumption. For the surveys, olive oil intake was measured on how often a volunteer used it: On salads

While baking

While cooking

When adding it to other meals and bread

In the study, one tablespoon equaled more than 13 grams of olive oil.

The scientists discovered that volunteers who consumed the most olive oil daily were 19 percent less likely to die from cardiovascular disease and 17 percent less likely to die from cancer. Results also showed that they were more protected from neurodegenerative mortality and respiratory mortality.

Guasch-Ferre explained that it is possible that higher olive oil consumption could be considered “a marker of an overall healthier diet and higher socioeconomic status.” After adjusting for these and other social-economic status factors, the study results remained largely the same.

She noted that the study cohort was made up mainly of a non-Hispanic white population of health professionals, which should minimize potential confounding socioeconomic factors. However, the study cohort may also limit generalizability as this population “may be more likely to lead a healthy lifestyle.”

The results showed that people with a higher olive oil intake were more likely to have an active lifestyle, follow a healthy diet and more likely to be non-smokers. Tips for incorporating olive oil into a balanced diet

Olive oil is the natural oil extracted from olives that come from olive trees. It is made up of 14 percent saturated fat and 11 percent polyunsaturated fat, like omega-6 and omega-3 fatty acids.

The predominant fatty acid in olive oil is oleic acid, a monounsaturated fat that makes up a whopping 73 percent of its total oil content.

Research suggests that oleic acid helps minimize inflammation. It may also have beneficial effects on genes linked to cancer .

Since monounsaturated fats are very resistant to high heat, extra virgin olive oil is a healthy choice for cooking.

Here are some suggestions on how to use more olive oil : Use olive oil in sauces. Whisk to emulsify or blend the watery ingredients with the oil in the sauce.

Use olive oil instead of butter or margarine as a healthy dip for bread. Pour a little olive oil into a small side dish, then add a bit of balsamic vinegar.

Drizzle olive oil in a salad or add it to salad dressing.

Use olive oil in marinades or sauces for meat, fish , poultry and veggies.

Add olive oil at the end of cooking for a healthy flavor boost.

Drizzle olive oil over cooked pasta or vegetables before serving.

Changing the Brain’s Immune Environment May Help Stroke Recovery

Changing the Brain's Immune Environment May Help Stroke Recovery

A therapeutic method for harnessing the body’s immune system to protect against brain damage is published today by researchers from the Babraham Institute’s Immunology research programme . The collaboration between Prof. Adrian Liston (Babraham Institute) and Prof. Matthew Holt (VIB and KU Leuven; i3S-University of Porto) has produced a targeted delivery system for boosting the numbers of specialised anti-inflammatory immune cells specifically within the brain to restrict brain inflammation and damage. Their brain-specific delivery system protected against brain cell death following brain injury, stroke and in a model of multiple sclerosis. The research is published today in the journal Nature Immunology .

Traumatic brain injury, like that caused during a car accident or a fall, is a significant cause of death worldwide and can cause long-lasting cognitive impairment and dementia in people who survive. A leading cause of this cognitive impairment is the inflammatory response to the injury, with swelling of the brain causing permanent damage. While inflammation in other parts of the body can be addressed therapeutically, but in the brain it problematic due to the presence of the blood-brain barrier, which prevents common anti-inflammatory molecules from getting to the site of trauma.

Prof. Liston, a senior group leader in the Institute’s Immunology programme, explained their approach: “Our bodies have their own anti-inflammatory response, regulatory T cells, which have the ability to sense inflammation and produce a cocktail of natural anti-inflammatories. Unfortunately there are very few of these regulatory T cells in the brain, so they are overwhelmed by the inflammation following an injury. We sought to design a new therapeutic to boost the population of regulatory T cells in the brain, so that they could manage inflammation and reduce the damage caused by traumatic injury.”

The research team found that regulatory T cell numbers were low in the brain because of a limited supply of the crucial survival molecule interleukin 2, also known as IL2. Levels of IL2 are low in the brain compared to the rest of the body as it can’t pass the blood-brain barrier.

Together the team devised a new therapeutic approach that allows more IL2 to be made by brain cells, thereby creating the conditions needed by regulatory T cells to survive. A ‘gene delivery’ system based on an engineered adeno-associated viral vector (AAV) was used: this system can actually cross an intact blood brain barrier and deliver the DNA needed for the brain to produce more IL2 production. Left : The top image shows an untreated mouse brain after a controlled impact, the site of damage can be seen by the dark circular impact site. The bottom brain is from a treated mouse 14 days after the impact, the absence of a visible impact site shows the success of the treatment in preventing brain tissue loss. Middle : These immunofluorescence staining images show how the treatment has reduced the amount of damage after traumatic brain injury when mice were pre-treated with the IL2 treatment. The top layer of brain tissue is visibly thicker in the bottom right image compared to top right. Each row shows the uninjured brain hemisphere (left) and the injured hemisphere (right). The top row shows an untreated brain while the bottom row shows a treated brain, with less damage occurring in the injured hemisphere. Right : A magnetic resonance imaging (MRI) scan of the brains of two mice after a controlled impact to create a traumatic brain injury. The arrow shows there the impact was made, the grey area below the arrow shows the size of the lesion. The amount of brain swelling is visibly reduced in the brain of the treated mouse (bottom).

Commenting on the work, Prof. Holt said: “For years, the blood-brain barrier has seemed like an insurmountable hurdle to the efficient delivery of biologics to the brain. Our work, using the latest in viral vector technology, proves that this is no longer the case; in fact, it is possible that under certain circumstances, the blood-brain barrier may actually prove to be therapeutically beneficial, serving to prevent ‘leak’ of therapeutics into the rest of the body.”

The new therapeutic designed by the research teams was able to boost the levels of the survival molecule IL2 in the brain, up to the same levels found in the blood. This allowed the number of regulatory T cells to build up in the brain, up to 10-fold higher than normal. To test the efficacy of the treatment in a mouse model that closely resembles traumatic brain injury accidents, mice were given carefully controlled brain impacts and then treated with the IL-2 gene delivery system. The scientists found that the treatment was effective at reducing the amount of brain damage following the injury, assessed by comparing both the loss of brain tissue and the ability of the mice to perform in cognitive tests.

Lead author, Dr Lidia Yshii, Assistant Professor at KU Leuven, explained: “Seeing the brains of the mice after the first experiment was a ‘eureka moment’ – we could immediately see that the treatment reduced the size of the injury lesion.”

Recognising the wider potential of a drug capable of controlling brain inflammation, the researchers also tested the effectiveness of the approach in experimental mouse models of multiple sclerosis and stroke. In the model of multiple sclerosis, treating mice during the early symptoms prevented severe paralysis and allowed the mice to recover faster. In a model of stroke, mice treated with the IL2 gene delivery system after a primary stroke were partially protected from secondary strokes occurring two weeks later. In a follow-up study, still undergoing peer review, the research team also demonstrated that the treatment was effective at preventing cognitive decline in ageing mice.

“By understanding and manipulating the immune response in the brain, we were able to develop a gene delivery system for IL2 as a potential treatment for neuroinflammation. With tens of millions of people affected every year, and few treatment options, this has real potential to help people in need. We hope that this system will soon enter clinical trials, […]

Scientists Find Brain Mechanism Responsible For Age-Related Memory Loss

Scientists Find Brain Mechanism Responsible For Age-Related Memory Loss

3D male medical figure holding head in pain Research suggests that the hippocampus, an area in the brain responsible for memory, performs two complementary processes: pattern separation and pattern completion.

Pattern completion could be described as the ability to remember visiting a place when you return there a month later, even if some details have changed. On the other hand, pattern separation is remembering which conversations happened during each visit and not confusing them with each other.

As humans and rodents age, their pattern separation abilities decline . Studies have shown that this may be linked to an overactive CA3 network in the dentate gyrus in the hippocampus. Drugs that reduce this hyperactivity have increased memory performance in aged rats.

A direct study of the CA3 network’s effect on memory could help researchers develop treatments to improve age-related memory issues. Most recently, researchers studied how this CA3 network influenced the memory abilities of young and aged rats.

The researchers found that some aged rats could perform similarly to young rats in memory tasks, even though their brains showed deficits in pattern separation.

For the study, the researchers obtained four young rats (aged between 3 and 6 months) and 14 older rats (aged between 22 and 26 months). To begin, the rats underwent behavioral testing in a water maze.

They then underwent hyperdrive implant surgery so that researchers could monitor the lateral edge of their CA3 brain region.

Thereafter, they were trained for eight days to locate a submerged escape platform in a water maze tank. Every sixth time in the maze was considered a ‘probe trial’, and included no escape platform for the first 30 seconds.

The researchers used the rats’ average search proximity scores during these probe trials to calculate a learning index. The mice with a score above 240 were categorized as “aged memory-impaired”, whereas those with a learning index of less than 240 were “aged memory-unimpaired”.

The researchers then further analyzed the rats’ cognitive abilities during foraging sessions, circular track training, and further water maze tests.

As expected, they found that aged memory-impaired older rats performed worse in various tasks than younger rats and that this corresponded with hyperactivity in certain parts of the CA3 area of the hippocampus.

They also found, however, that some of the aged memory-unimpaired rats performed similarly to young rats, even though they showed signs of the same changes in their CA3 regions. Underlying mechanisms

To explain the findings, the researchers noted that in neurological conditions such as Alzheimer’s and Parkinson’s, there is little behavioral deficit until a threshold is crossed.

They said this may explain why some older rats performed similarly to younger rats, given their maze scores occurred on a continuum between the scores of the younger rats and those of the most impaired older ones.

When asked about the underlying mechanisms, Heekyung Lee , from the Knierim Lab at John Hopkins University and the primary author of the study, told Medical News Today that inhibitory neurons may play a role.

“The number of inhibitory neurons declines with age in the hippocampus. Prior work […] has shown that while inhibitory neurons in multiple subregions of the hippocampus decrease both in memory unimpaired (AU) and memory-impaired (AI) aged rats, inhibitory neurons specifically in the hilus of the dentate gyrus subregion decrease in AI, but not AU rats,” Lee explained.

“It is noteworthy that there are complex feedforward and feedback connections between the dentate gyrus and proximal CA3, two subregions that support pattern separation computations. The balance of excitation and inhibition plays an essential role in network dynamics,” she added. “One possible compensation mechanism in [aged] rats [with unimpaired memory] can be that the preservation of inhibitory neurons exclusively in the [brain’s] hilus region may be enough to overcome the age-related excitation-inhibition imbalance to favor pattern separation.” — Heekyung Lee, study author Dr. Tara Swart Bieber , neuroscientist and professor at MIT Sloan School of Management, told MNT that neuroplasticity might also play a role.

“Neuroplasticity—the ability to re-wire our brains throughout life—is likely to be the mechanism that underpins this compensation. Although harder in later life, it is possible to make new connections that can bypass pathways that have become weak. […] Also, people can fully recover after a stroke or brain surgery,” she said. The next steps

The researchers concluded that further research is warranted to understand the compensatory mechanisms in aged memory-unimpaired rats to understand how they prevent age-related cognitive decline.

When asked about future research directions, Lee said that determining different subtypes of neurons would be key for targeted therapies. “Future research to understand why inhibitory neurons are vulnerable to aging can help discover therapeutic strategies to increase inhibition in the hippocampus to help improve age-related memory issues.” — Heekyung Lee, study author “Furthermore, there are different subtypes of inhibitory neurons, and understanding the functional specificity of each subtype can allow for targeted intervention,” she added.

Dr. Bieber also said that research into lifestyle habits that may help older people manage age more efficiently could also improve understanding of these compensatory mechanisms.

When asked more generally about preventing age-related memory decline, Dr. Bieber said:

“Taking on new learning throughout your life, that is attention intense enough to change your brain, e.g., learn a new language, sport, musical instrument, etc. is the best thing you can do for your brain in adulthood.”

6 Scientifically proven benefits of green tea

6 Scientifically proven benefits of green tea

( Natural News ) If you drink tea often, especially green tea, you have new reasons to keep drinking it.

Green tea has been the focus of many studies and findings show that drinking green tea regularly offers various health benefits , such as reducing bad breath and promoting weight loss. Where does green tea come from?

For many years, tea has been used for therapeutic purposes in China and Japan.

The black, green and oolong teas all come from the Camellia sinensis plant. The difference between the teas lies in their preparation methods.

Green tea is made by steaming the leaves, pan-frying then drying them.

Since brewed green tea is primarily water-based, it’s free of the usual macronutrients found in other foods and drinks. Green tea doesn’t contain any fat , carbohydrates or protein. Unsweetened green tea is also calorie-free.

Green tea’s many health benefits are often accredited to compounds called catechins, specifically epicatechin , epicatechin-3-gallate, epigallocatechin and epigallocatechin gallate (EGCG). Experts think that these catechins are responsible for green tea’s potential “cancer-fighting, antioxidant, probiotic and metabolism-boosting benefits.”

It also contains trace amounts of potassium and moderate levels of caffeine. A cup of green tea contains 25 to 29 milligrams (mg) of caffeine.

Green tea is a popular beverage and it is often enjoyed in many countries worldwide.

Read on to learn more about the six evidence-based benefits of green tea. Green tea has neuroprotective properties

According to research published in the Journal of Alzheimer’s Disease , amyloid-beta protein has been shown to have a causal relationship with the development of dementia . Modulating amyloid-beta protein is a potential therapeutic modality that should be considered for further study. Green tea has neuroprotective properties, particularly its reactive oxygen species (ROS) scavenging activity that can prevent oxidative stress.

The tea also contains EGCG, which suppresses the neurotoxicity induced by amyloid-beta protein. Scientists suggest that EGCG can help trigger glycogen synthase kinase-3 beta (GSK-3 beta) and also inhibits c-Abl/FE65 or the cytoplasmic nonreceptor tyrosine kinase with a role in nervous system development and nuclear translocation.

According to findings published in the journal Pharmacology & Therapeutics , when stimulated, many proteins translocate into the nucleus to regulate many different cellular processes that are crucial for brain health. These factors make green tea a potential agent to address neurodegenerative diseases like Alzheimer’s disease. Green tea has anticancer properties

Drinking green tea can also help prevent bladder, breast, esophagus, intestinal, lung, pancreatic and stomach cancers .

According to a 2020 article published in the International Journal of Molecular Sciences, EGCG has the best anti-inflammatory and anticancer potential because it triggers apoptosis or cell death.

Researchers indicate that the control of catechins under an intracellular pool of nitro-oxidative stress is the primary reason for the potential anticancer properties. Additionally, catechins also scavenge harmful free radicals that are linked to chronic diseases. (Related: Drinking tea regularly linked to reduced cardiovascular disease risk .) Green tea helps reduce fat and promote weight loss

Many fat-burning supplements contain green tea extract because this ingredient helps boost your metabolic rate.

Data from an older study published in the American Journal of Clinical Nutrition has shown that green tea extract helped increased the number of calories burned by four percent in 10 healthy male participants. The extract can also help improve physical performance due to the increase in available energy because of the stimulation of caffeine and other compounds.

In a 2017 systematic review published in the journal Nutrición Hospitalaria , researchers examined the effects of green tea and its EGCG content on human fat mass and body weight. Findings showed that the daily consumption of green tea with EGCG doses between 100 and 460 milligrams per day effectively reduced body fat and weight in intervention periods of at least 12 weeks. Green tea improves focus and boosts energy

If you have trouble concentrating but don’t like drinking too much coffee, you can improve your focus with green tea. An eight-ounce cup of brewed green tea contains 28 milligrams of caffeine, which is enough to stimulate both your body and brain without the jittery effects caused by overconsumption.

Green tea boosts your focus and energy because it contains caffeine that blocks adenosine, an inhibitory neurotransmitter.

Additionally, caffeine boosts dopamine and norepinephrine signaling in the brain. This then helps improve your reaction time, memory and mood. Green tea helps fight bad breath

Green tea catechins benefit your oral health by suppressing the growth of harmful bacteria.

Streptococcus mutans is a type of bacterium that often causes plaque and contributes to tooth decay and cavities. While there is no research on whether or not green tea can eliminate this bacteria, data suggests that green tea can help reduce bad breath (halitosis).

In a 2008 study published in the Journal of Nutritional Science and Vitaminology , scientists analyzed the effects of green tea powder on volatile sulfur compounds in the mouth.

Findings showed that polyphenols in green tea had deodorizing and antimicrobial effects. Green tea extract presented the largest reduction in these bad breath compounds by significantly decreasing oral malodor temporarily. Green tea helps improve skin health The protective polyphenols in green tea can help increase collagen, improve elastic content and prevent wrinkles. A 2017 review published in the journal Critical Reviews in Food Science and Nutrition suggests that these compounds may also have antioxidant and anti-inflammatory properties.In a 2021 meta-analysis published in Phytotherapy Research , scientists analyzed the effects of green tea extract on acne vulgaris across five randomized clinical trials.Review findings showed that topical green tea extract application benefits acne treatment without significant adverse events. On the other hand, oral GTE intake presents limited effects.Topical green tea extract offered benefits for both inflammatory and non-inflammatory lesions in the studies examined by the research team.If you’re still on the fence about trying green tea, take this as a sign to start drinking this beneficial beverage. Consuming green tea regularly can offer many benefits, such as improving your skin health and lowering your risk of developing neurodegenerative diseases and certain cancers.Visit Superfoods.news for more articles about foods that offer […]

Why Your Gut Could Be the Key to Preventing Anxiety, Alzheimer’s, and More

Why Your Gut Could Be the Key to Preventing Anxiety, Alzheimer’s, and More

If you’ve ever experienced butterflies in your stomach before a speech, you knew the sensation didn’t result from a lost monarch. But this common experience—your gut seeming to act out your brain’s anxiety—is an everyday example of fascinating new research into the interconnected worlds inside us.

While your stomach doesn’t contain butterflies, there are tiny organisms in there that are engaged in a conversation with your brain about that stress you’re experiencing. These organisms and their home could be far more powerful than we’ve realized, according to a burst of new studies. Many of the tens of trillions of organisms in your gut, or gastrointestinal tract, can help maintain good digestion and health . But some of them are not so cooperative: When they take over, they wreak havoc. That might mean you get food poisoning or make more bathroom trips than you’d like—but some might have bigger implications. These nasty bugs could be sending the brain signals connected to brain-related disorders including anxiety and Alzheimer’s disease .

So, is your gut the key to a healthy brain? Here’s what you need to know about the gut-brain connection. What is the gut microbiome?

With the help of everyday people, University of California San Diego researchers have uncovered new facets of the worlds within us. As part of the American Gut Project , more than 10,000 people from around the world mailed in their poop (yep). Scientists analyzed it to understand how organisms inside us—our microbiomes—interact with diet, lifestyle, and disease.

Learn more about the powerful gut-brain connection in a free webinar on June 9 , moderated by Joan Lunden and hosted by Prevention , HealthyWomen , and the Women’s Alzheimer’s Movement at Cleveland Clinic .

You may remember the word “biome” from biology class—a habitat such as desert or grassland, designated based on local climate and plant life. Our bodies contain their own worlds, unique habitats of trillions of wee beasties—viruses, fungi, bacteria, and other microorganisms living on us and inside us. In humans, microbes gather in these worlds on the skin, in the nose , and in the gastrointestinal tract (a.k.a. the gut). Over the past 20 years, experts have refined techniques to “fingerprint” the gut’s cast of microbes through sequencing DNA, says Ami Bhatt, M.D., Ph.D. , an associate professor of medicine and genetics at Stanford University.

You’ve had a microbiome since the day you were born, and it’s been evolving and growing with you. On your ride through the birth canal, your gut filled with a wide cast of microorganisms passed along by your mom. Then skin-to-skin contact, first foods, infections (and antibiotics), and all those germy toys changed your microbiome. Each new interaction, from childhood on, brings in guest stars, removes old standbys, and casts long-term recurring roles— your gut’s world is constantly in flux.

Animal and human research has found that the gut microbiome can be influenced by environmental factors such as chronic stress, artificial sweeteners, pesticides, disinfection, and ultrafine particles in polluted air. You can pick up new gut bacteria from your pet or a bad meal, Dr. Bhatt notes. Ultimately, microbial worlds wholly unique to you inhabit your body.

Helpful gut microorganisms have processes for breaking down foods and turning them into ingredients our bodies use. They develop the immune system, block pathogens, synthesize vitamins , and more. How the gut talks to the brain

In the past, you’ve probably lost your appetite because of stress or sadness—or falling in love. Maybe you’ve “followed your gut” or made a “gut decision.” These familiar terms and experiences clue us in to why some researchers are now calling the gut our “second brain” and saying bacteria may be the “master puppeteers” of our brains.

Scientists aren’t sure yet how the gut’s microbiome influences the brain—but it seems to be a fascinating two-way relationship. For example, among middle-aged adults, a more diverse microbiome was associated with better performance on cognitive tests . Various theories posit that the gut produces molecules that signal the brain via the bloodstream or the enteric nervous system . For example, specific gut bacteria can detect and increase the production of serotonin, which is associated with feelings of contentment. In fact, 90% of the body’s serotonin is made right in the gut . Another kind of bacteria commonly found in the human gut, Lactobacillus rhamnosus , actually contains a neurotransmitter that can help calm anxiety . Other bacteria may influence our social behavior and interactions and our responses to stress.

“It’s a two-way street of feedback loops” between the gut and the brain, says researcher Laura Cox, Ph.D. , a Harvard assistant professor seeking to understand how the microbiome can affect the brain in aging. What happens in the brain when gut bugs go bad

Sometimes unhelpful critters stage a takeover of the gut. This overpopulation can lead to gut dysbiosis , a negative imbalance that seems to cause static in the body’s communication lines and influence the brain’s everyday work. For example, gut dysbiosis is associated with depressive-like behaviors. In an animal study, transferring a mood-disordered animal’s gut bacteria into a healthy animal led to depressive symptoms for the formerly well animal, says Smita Patel, D.O., a neurologist and sleep specialist at iNeuro Institute . Other research is investigating the links between the gut microbiome and ADHD , autism spectrum disorders , anxiety , and stress . Unhelpful gut microbes may create irritants to the immune system that travel through the bloodstream and influence the brain’s immune cells. For example, the guts of Alzheimer’s disease patients show a lack of diversity compared with those of similar adults and are often overpopulated with a specific microbe. This microbe may impair immune functions related to clearing a plaque built upon the brain’s structures that is related to Alzheimer’s symptoms . Sex-based differences come into play as well, says Cox. The gut microbiota can regulate levels of hormones, including estrogen. When gut dysbiosis sets in, estrogen levels can change, possibly influencing cognitive decline.

Fascinating research is now being done by the Alzheimer Gut […]
