"70 is the new 50."
Scientists from Switzerland have proven that daily intake of omega-3 can slow down the aging process of the body. The study involved 777 individuals aged 70 and older. The results of their work were published in the journal Nature Aging.
It was found that healthy older adults who took one gram of fatty acids daily for three years had a biological age that was three months lower compared to other participants. Additionally, the inclusion of vitamin D and physical exercise (three times a week for 30 minutes) enhanced the effect to nearly four months.
Researchers used biological tools known as the epigenetic clock to assess the impact of the supplement on the aging rate. The epigenetic clock consists of a set of specific DNA markers that allow for the determination of the biological age of tissues, cells, or organs.
Previous studies indicated that omega-3, found in fatty fish, nuts, seeds, and other products, could slow down aging processes. However, until recently, it remained unclear whether significant results could be achieved through supplementation.
Scientists also noted other beneficial properties of fatty acids, including a 10% reduction in fall frequency among older adults by 10% and a 13% decrease in infections. Furthermore, the combination of omega-3, vitamin D, and regular physical exercise reduced the risk of developing prediabetes (by 39%) and also decreased the incidence of invasive cancer types (by 61%).
Researchers emphasize that the study results are preliminary. Moreover, it is still unknown whether slowing aging in this way can lead to a longer and healthier life.
