Editor's Note -- October 5, 2009: Elizabeth H. Blackburn (mentioned below), Carol W. Greider and Jack W. Szostak have just won the Nobel Prize in Physiology or Medicine for their breakthrough work on telomerase, which was discussed in a
Reader's Digest article (see below) published earlier this year.
DNA Life Changer
Healthy habits can actually repair your DNA, say researchers Dean Ornish, MD, and Elizabeth Blackburn, MD. Their study subjects ate vegetarian whole foods with 10 percent of calories from fat, walked 30 minutes six days a week, used stress-reducing techniques, and went to a weekly support group. The results? Besides a decrease in LDL cholesterol and stress levels, they showed a 29 percent rise in telomerase. This enzyme repairs and lengthens telomeres, tiny protein complexes on the ends of chromosomes that are vital for immunity and longevity. Short telomeres and low levels of telomerase signal an increased risk of heart disease and cancer, plus a poor prognosis if you do get ill.
