The top 5 vitamins and minerals to boost your brainpower
Sept. 22, 2004 -- We all know by now that eating a healthful diet rich in whole grains, fruits, and vegetables can help us stay slim and lower our risk for heart disease, but did you know that a growing body of research shows that this type of diet also preserves memory, boosts alertness, and may even stave off the blues and prevent Alzheimer's disease!
It's true! "Nutrition plays a significant and crucial role over the long run and the short run in brain health," says Ray Sahelian, MD, a Marina Del Ray, Calif.-based physician and author of Mind Boosters. "We can maintain a healthy and active mind well into our 80s and 90s by eating properly," he tells WebMD.
Eating More E
"For a long time, people believed that a common component of vitamin E called alpha tocopherol was most important, but another form called gamma tocopherol is definitely a protective antioxidant in brain disorders," says Aimee Shunney, ND, the coordinator of the educational and wellness program at Long Island College Hospital in Brooklyn, N.Y.
When you consume food rich in vitamin E, including almonds, green leafy vegetables, corn oil, sunflower oil, hazelnuts, and whole-grain flour, you get both alpha tocopherols and gamma tocopherols, she says. If you are choosing supplements, look for vitamin E with "mixed tocopherols" and take 400 IU a day, she says. Vitamin functions as an antioxidant and the brain is particularly susceptible to free radicals (damaging, unstable molecules). Some research indicates that vitamin E can delay progression of Alzheimer's disease and/or prevent it from occurring in the first place by reducing the free radicals damage!
B Good to Yourself
"B vitamins are involved in helping the formation of brain chemicals such as dopamine, epinephrine, and serotonin," Sahelian says. In fact, each B vitamin plays its own role in preserving brain function and mental acuity. Starting from folic acid (a B complex), which helps in the early brain development, these vitamins help in many aspects of metabolism. A few recent studies have shown a link between declines in memory and Alzheimer's disease in the elderly and inadequate levels of folic acid, vitamin B12, and vitamin B6. Reduced levels of folate are associated with high levels of homocysteine -- a marker of heart disease and stroke.
