4、 crash just as quickly. Better choices may be Brazil nuts(for selenium), skim milk(for calcium), or a spinach salad(for folic acid).

5、n. You want to be sharp, but you usually feel sleepy after lunch. Is your best choice an energy fix of fries and a shake or a broiled chicken breast and low-fat yogurt?

12、also enhance brainpower. Choline is a substance similar to the B vitamins. Its found in egg yolks, whole wheat, peanuts, milk, green peas, liver, beans, seafood, and soybeans. The brain uses it to make the neurotransmitter acetylcholine. To test the effects of choline on memory and learning, researc
