Cranberries

This born-and-bred American berry is among the top 10 antioxidant-rich foods, making it a potent cancer protector. You know it helps treat urinary tract infection, and perhaps you heard it prevents gum disease, too, but did you know that these beneficial berries may:

Eradicate E. coli

Compounds in the juice can actually alter antibiotic-resistant strains, making it impossible for the harmful bacteria to trigger an infection. A small pilot study from Harvard Medical School and Rutgers University found that eating about 1/3 cup of dried cranberries yielded the same effect.

Help prevent strokes

Research on pigs with a genetic predisposition to atherosclerosis--narrow, hardened arteries that may lead to heart attack and stroke--found that those fed dried cranberries or juice every day had healthier, more flexible blood vessels.
