Tea drinkers, take heart. Research done in the Boston area indicates drinking at least two cups of black or green tea a day could reduce your chance of dying after a heart attack by 44 percent. Scientists believe there's something in tea that protects the heart. Researchers studied 1,900 heart attack survivors for four years. Even the patients who drank fewer than 14 cups a week had a 28 percent lower death rate than those who didn't drink any tea at all. And finally, "Consumer Reports" magazine went straight to the source to find out which diet works best. According to 32,000 dieters the magazine talked with, the overwhelming majority of successful losers said exercise made the difference, not food deprivation. However, the dieters stayed with traditional healthy foods, and most claimed it was dieting on their own, and not on expensive diet programs, that worked.
