Thompson Seedless and Concord.
- Young African-Americans tested low in vitamin D in a 14-city survey.
- Choline--found in eggs, peanuts, dairy products, bacon and other familiar
foods--helps halt the homocysteine buildup associated with higher risk of heart
attack, dementia, stroke and cancer.
- Female volunteers who ate a high proportion of
"high-glycemic-index" foods over a 10-year period were more than
twice as likely to develop an early indicator of age-related macular
degeneration, one of the leading causes of irreversible vision loss in America.
- Consuming less than the recommended level of zinc may interfere with the
activity of a zinc-dependent enzyme, carbonic anhydrase, making the heart need
to work harder during exercise.
