A study conducted by the Kronos Longevity Research Institute (KLRI) has found that a diet high in omega-3 fat will improve your insulin sensitivity and reduce inflammatory markers. But, a diet high in omega-3 fat will not alter endocrine responsiveness. The study was recently published in Hormones and Metabolic Research.

Omega-3 fatty acids are polyunsaturated fatty acids found in certain foods like fish–especially salmon and tuna. Omega-3 fatty acids are known to help protect against heart disease. The Kronos Longevity Research Institute looked at the effects of a diet high in omega-3 fatty acids on the loss of normal hormone balance that occurs during normal aging. The Kronos Longevity Research Institute asked men and women over the age of 60 to investigate whether a high omega-3 fatty acid diet would improve their endocrine function.

According to the Kronos Longevity Research Institute, “all participants were given a conventional Western diet with defined fat and daily intake of olive/corn oil mix for six weeks. For the next eight weeks, participants were placed on a high omega-3 content fish diet with additional supplementation of fish oil, high in omega-3 polyunsaturated fat. This study had administered the highest known level of omega-3 than previous studies.

During the last week, membrane fatty acids were measured on each diet. Insulin sensitivity was also assessed. The results showed that in a diet with a high intake of omega-3, triglycerides were reduced in women and free fatty acids were reduced in men. Serum C-reactive protein was also reduced with a high omega-3 diet. No changes were found in metabolic parameters or hormone responses.”

The Kronos Longevity Research Institute says that “these findings are consistent with other studies that have found that diets high in omega-3 and/or omega-3 supplements have anti-inflammatory benefits. Omega-3 fats are abundant in Japanese and Mediterranean diets, and are believed to contribute to low heart disease rates in those regions.”

Kronos Longevity Research Institute (KLRI) is a not-for-profit, 501(c)(3) organization that conducts state-of-the-art clinical translational research on the prevention of age-related diseases and the extension of healthier human life. KLRI tests new strategies to detect and prevent chronic diseases associated with aging and investigates the effects of innovative interventions to slow the aging process and improve health outcomes for older persons. In addition, KLRI helps the medical and lay communities understand important aging issues. KLRI research findings support a healthier quality of life and a robust lifestyle in our senior years.
