Proper brain function is dependent upon good nutrition. Omega-3 fatty acids, B vitamins, and zinc are all key nutrients for brain tissue. Vitamin B12, folate, and vitamin B6 are involved in the production of neurotransmitters, and zinc has antioxidant effects in the brain. The omega-3 fatty acids DHA and EPA are important for the structure of brain cell membranes. Inadequate levels of each of these nutrients have been linked to a greater risk of depression.

Protection against oxidative stress makes plant food-derived antioxidants beneficial for the brain. Also, many phytonutrients have anti-inflammatory and other non-antioxidant functions that may also enhance brain health.
