1 avocado a day for 6 months can improve brain function in senior citizens: Study

( Natural News ) There’s a lot to be said of the health benefits of avocados. They are an excellent source of healthy unsaturated fats, as well as omega-3 fatty acids. In older adults especially, the fruits increase lutein levels in the brain and eyes which significantly improves cognitive functions, a study in the journal Nutrients reported . The study, conducted by scientists from Tufts University , found that for adults aged 50 and older, those who ate a fresh avocado a day had increased their lutein levels in their eyes and demonstrated improved working memory and problem-solving skills. Lutein is a carotenoid found in yellow- and orange-colored fruits and vegetables like mangoes, corn, sweet potatoes, carrots, squash, tomatoes and dark, leafy greens such as kale, collards and bok choy. The carotenoid is famous for its ability to protect against common eye disorders such as cataracts and macular degeneration. In addition, lutein and zeaxanthin absorb harmful blue light from the sun, which can damage the retina. A further study of the compound revealed that it plays a role in preventing blood clots in the carotid artery in the neck, one of the indicators for atherosclerosis. In contrast, a deficiency in lutein showed a worsening of arterial clogging. Still, experts haven’t fully explored its effects in the human body, including the best route for nutrient absorption. In a study, participants added one medium avocado to their daily diet . The researchers then measure their lutein levels and any improvement in cognition using various tests for memory, processing speed, and attention level – where their results were compared with that of a control group, which had either one medium potato or a cup of chickpeas, in place of the avocado . Researchers used chickpeas and potatoes since both have a calorie […]
