Science has long understood that certain nutrients can increase concentration, enhance memory and diffuse stress. Today, medical research increasingly shows that certain foods can protect your brain from age-related deterioration and illness and make the most of brain function, making you smarter and sharper. Here are the foods and nutrients you need to enhance memory and mental focus and protect your brain health.
B Vitamins
Essential to brain health, B vitamins are the building blocks for neurotransmitters. For example, choline and vitamin B12 are both needed to create the neurotransmitter acetyl-choline, which is responsible for memory function. B vitamins are found in large quantities in legumes (kidney beans, chickpeas, lentils) as well as leafy green veggies and orange juice. Eggs, brewer’s yeast, wheat germ and soy products are very rich sources of choline. Vegetarians may find it difficult to get enough B12 in their diets because it’s not abundant in plant foods. However, soy foods such as miso and tempeh are good sources.
Antioxidants
Think rainbow foods. Brightly hued fruits and veggies are loaded with antioxidant vitamins like C, E and beta-carotene. These nutrients are necessary to keep arteries clean for maximum blood and oxygen flow to the brain. Antioxidants also clean up the free radicals that damage cells in the body and brain. Vitamins C and E in particular inhibit blood clotting which helps to prevent strokes. Research has also shown that vitamin E is useful in preventing Alzheimer’s disease.
Fill up on dark green leafy veggies like spinach, collard greens and kale. Eat more cruciferous veggies like broccoli, cabbage and Brussels sprouts. Deep red, yellow, blue and orange produce like tomatoes, red peppers, cantaloupe, carrots, apricots, red grapes, blueberries and raspberries contain high concentrations of antioxidants too.
Protein
Builds brain tissue and triggers the creation of the neurotransmitters norepinephrine and dopamine which are responsible for clear thinking, attention and concentration. Lower fat proteins such as soy milk and textured vegetable protein, low-fat yogurt and legumes are good choices. Higher fat proteins like cheese and peanut butter require more energy to digest and slow the production of dopamine and norepinephrine which can dull mental sharpness.
Good Fats
Omega-3 and omega-6 fatty acids (EFAs) and monounsaturated fats enhance brain function. These healthy fats are found in nuts such as walnuts, nut oils like olive and flaxseed, avocados, and fish like salmon and tilapia. Research also shows that they protect the brain from damage and heal it once damage occurs. A diet that is too high (more than 20 grams per day) in saturated fat is bad for your brain as well as your heart. Too much saturated fat can slow you down and lead to clogged arteries and ultimately a stroke. Vegetarians can find EFAs in dried seaweeds such a nori and kelp that are usually found in natural food stores.
Good Carbs
Eating complex carbohydrates will stimulate the creation of the relaxing brain chemical serotonin, which can help us focus in times of stress. Good sources of complex carbs are fruits and veggies, whole grains and pasta. Complex carbs work best when paired with low-fat proteins and fiber as this combination prevents the neurotransmitter tryptophan from flooding the brain and making us groggy.
Of course, heredity, age and environment all factor into building a sharp mind, but giving your brain the nutrients it needs will help you make the most of what you’ve got.
