Telomeres may be a key to younger biological age
People with higher levels of omega-3s and men who drank the most green tea had longer telomeres, a sign of younger, healthier cells, new studies reveal
Telomeres—the protective caps at the ends of chromosome DNA strands that contain our genetic code—are like the tip of a shoelace that keeps it from unraveling. When a cell divides, the new cell must take with it a complete copy of the DNA strand to function properly. Long, healthy telomeres on the ends of each chromosome allow the new cell to get a complete DNA copy. Age, stress, and poor nutrition can erode telomeres, eventually damaging chromosomes and any new cells. Doctors are beginning to gauge biological age by telomere length....
