You may recognize this nut as the nut that you bake with, but walnuts are a great option for your brain health. First of all, walnuts are loaded with omega-rich fats, which are ideal for reducing inflammation in your body and in your brain. Second, walnuts contain vitamin E, which helps to improve the vasculature in your brain. Improving the vasculature can help to improve blood circulation to the brain and help your overall focus. Studies have shown that a serving of walnuts can help improve your cognitive health and help to fight off symptoms of Alzheimer’s disease. Be mindful that a handful of walnuts is about 200 calories, so make sure to have only a handful per day.
