7 foods that are good for your brain
Egg yolks are no joke. They contain choline -- a chemical building block of every cell. Scientists studying the effects of choline on memory in rats found that rats that got plenty of choline prenatally don't seem to develop senility in old age. Studies in adult humans have found that boosting choline intake can improve memory. Egg yolks are among the richest natural sources of choline. Skim milk has choline as well. AJC file photo
