Back in 2009, the secret to living forever—okay, not forever, but longer—lay in telomere preservation. Telomeres are the endcaps of DNA strands in our chromosomes—think plastic tips on shoelaces. The telomeres get shorter with each cell replication, and when the telomeres get too short, the cell dies.
So you could say that the fountain of youth—or at least a trickling tributary—can be found in the vitamins that preserve telomeres and therefore lengthen cell life. Chief among these is vitamin D. A study published in the American Journal of Clinical Nutrition showed that higher levels (about 50 ng/ml of vitamin D) were associated with as many as five additional years of life thanks to telomere preservation.
A new study published in the online advance edition of the European Journal of Clinical Nutrition confirms that vitamin D is even more important to longevity and disease avoidance than we may have thought. The researchers found that doubling serum 25-hydroxyvitamin D (25(OH)D) levels—to, again, about 50 ng/ml—would reduce the global vitamin D–sensitive disease mortality rate by an estimated 20 percent.
Vitamin D–sensitive diseases account for more than half of the global mortality rate and include cardiovascular disease, cancer, respiratory infections, respiratory diseases, tuberculosis and diabetes mellitus. The estimated increase in life expectancy, simply by doubling serum vitamin D, is two years. Globally.
