Beat Stress

Science has confirmed that the nutrients in our food can slow down and even reverse aging. Here's exactly how and when you can expect the health payoff you want:

Vitamin B6 deficiency has been linked to anxiety, stress, and depression, and women are more likely to become deficient in B6 as they age, according to researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University. "When B6 makes its way to your brain, it facilitates synthesis of neurotransmitters, such as dopamine, which makes you feel calm and happy," says Hanjo Hellmann, Ph.D., a plant biologist at Washington State University. "But if you have a B6 deficiency, your brain may not be able to make enough dopamine." The vitamin is found in a variety of foods, but it's especially high in potatoes, bananas, red meat, poultry, and chickpeas. Once eaten, B6 is quickly distributed throughout the body but isn't stored well, so we need a consistent daily supply. Hellmann recommends getting 1 to 2 mg of B6 every day—the amount in about one medium russet potato and a chicken breast—to help you produce enough stress-busting dopamine.
