Flaxseed: a Natural Alternative to Cholesterol Drugs A
new study from Iowa State
University’s Nutrition and Wellness Research Center may give men a way to combat high cholesterol without drugs—if they don’t mind sprinkling some flaxseed into their daily diet.
In the study,
researchers examined the effects of eating flaxseed lignans (natural plant chemicals found in flaxseed) on 90 people diagnosed with high cholesterol. The results showed that consuming at least 150 milligrams per day (about three tablespoons) decreased cholesterol in men by just under 10 percent over the three months of the study. They did not see similar results in women.
Suzanne Hendrich, a professor of food science and hu- man nutrition at the university who led the study, notes that the flaxseed tablets used in the research are not available in the United States, but sprinkling ground flaxseed on cereal and other foods can provide ample cholesterol-lowering flaxseed lignans. Ground flaxseed will oxidize over time, she says, possibly affecting its flavor as well as omega-3 content, so keep it fresh.
RENEWS ITSELF Researchers at Karolinska Institute, a lead- ing medical university in Sweden, have demonstrated that contrary to conven- tional theory, heart cells are able to regenerate themselves. Examining the heart tissue of 50 people over the course of four years, the researchers found that new heart cells ap- peared to replace older ones at a rate of approximately 1 percent per year in people in their 20s, falling to 0.5 percent per year by age 75. Scientists now hope to find ways to stimulate this natural regen- eration of heart cells as a way to avoid heart transplants and help people recover from heart attacks.
