Study Finds Higher Omega-3 Fatty Acid Levels Associated With Less Biological Aging in Cardiovascular Disease Patients

UCSF scientists have discovered that higher blood levels of omega-3 fatty acids correspond to a lower rate of shortening of telomere length in patients with coronary artery disease.
The finding, they say, indicates the possibility that omega-3 fatty acids may protect against cellular aging.
The study is reported online and in the Jan. 20 issue of the Journal of the American Medical Association.
Telomeres are tiny units of DNA that seal off the ends of chromosomes, which contain the body’s genes — similar in concept to the tips that keep shoelaces from unraveling. Telomeres protect the integrity of genes and maintain chromosomal stability and accurate cell division. They also determine the number of times a cell divides, and thus determine life span.
