Increased Omega-3 Fatty Acid Consumption May Impact The Aging Process At The DNA Level

October 1, 2012: 12:00 AM EST
The symptoms of aging could be significantly decelerated if people were able to change the ratio of fatty acid consumption in a way – such as consuming more omega-3 fatty acids – that preserved the tiny segments of white blood cell DNA known as telomeres. The segments are known to constrict over time in many types of cells as a consequence of aging. But consuming enough omega-3 fatty acid supplements seems to lengthen telomeres in immune system cells, while also reducing oxidative stress. According to the researchers, the findings suggest that “a nutritional supplement might actually make a difference in aging.”
