HealthWise at 5 From 6.4

  • Chocolate Health

More evidence that chocolate may be good for your heart health! A new study finds small, daily doses of dark chocolate improved the blood vessels' ability to dilate. In the study, 11 healthy volunteers consumed the equivalent of a chocolate bar every day, always dark chocolate. Those who ate the rich dark chocolate had much better blood flow at the end of two weeks. Researchers say flavonoids seem to trigger the release of substances that increase blood flow, including flow to the heart. The study was conducted at the University of California in San Francisco.

  • Kids Prozac

Early results of a landmark government study may help bring some answers in the debate over the use of antidepressants in youngsters. The study finds the drug Prozac works better than talk therapy in treating depression in teens. The research included more than 400 young people from age 12-17 who were suffering from moderate to severe depression. After three months, between 60 and 70%of the patients who received Prozac responded well, compared to an average of just 40% who were treated with talk therapy or a sugar pill. Actually, Prozac was the most effective when it was combined with talk therapy. But researchers note that while all the patients in the study became less suicidal, regardless of the treatment, the risk remained the highest in patients who got Prozac. The study was sponsored by the National Institute of Mental Health.

  • Vitamin-Knees

It may help prevent heart disease and even cancer, but new research suggests too much vitamin "C" may end up hurting your knees. The study in guinea pigs finds the animals that got high doses of vitamin C developed more bone spurs in their knees compared to those on medium and low doses. The Duke researchers note that guinea pigs develop knee osteoarthritis much like people do. When they examined the bone spurs, they found a protein that can be activated by vitamin C. The high dose group in the study got between 1,500 to 2,500 milligrams a day, well above the recommended limits which are 90 milligrams a day for men and 75 a day for women. Researchers say the findings suggest that adults may want to reconsider before taking supplements in mega-doses.
