The omega 3, essential fatty acids, are a valid help to reduce the negative effect of stress on health. To say it is a new one studio conducted by researchers fromInstitute for Behavioral Medecine Research, The Ohio State University College of Medecine, in the United States, which analyzed how the daily intake of omega 3 can slow down aging and enhance cell protection during a stressful moment.
Compared to the placebo group, the participants (healthy men and women in their 50s) who took 2.5 g of EPA and DHA every day produced less cortisol, the stress hormone, and lower levels of pro-inflammatory cytokines. during a stressful event in the laboratory.
Not only that, each of them recorded a lower inhibition of the activity of the telomerase enzyme, which repairs the damage to DNA caused by stress.
Omega 3 supplementation contributed to what researchers call it resilience to stress: reduction of damage during stress and, after acute stress, sustained anti-inflammatory activity and protection of cellular components that shrink due to aging. The potential anti-aging effects were considered particularly evident because they occurred in healthy but also sedentary, overweight and middle-aged people, all characteristics that could lead to a greater risk of accelerated aging. The key to longevity lies, in fact, in the optimization of the internal resolution response of the organism to inflammatory damage.
«For those with a very stressful job, the daily intake of adequate levels of EPA and DHA, adequate supplementation with omega 3, can represent the best defense against inflammation and DNA damage associated with that specific occupation. The same goes for professional athletes, subjected to constant stress, between training and competitions. However, many of us live with low intensity chronic stress. Its impact on the immune system? It is the same “, commented Dr. Barry Sears, Ph.D, creator of the Zone diet and President of the Inflammation Resarch Foundation. “In all likelihood, we will never be able to eliminate stress from our lives. The continuous intake of adequate levels of EPA and DHA still allows us to significantly reduce the genetic and inflammatory consequences induced by stress ».
OTHER BENEFITS OF OMEGA 3
Omega 3 are essential fatty acids, and this means that the human organism is not able to synthesize them, which is why they must be taken through the diet. There are two forms: short-chain, found in vegetables and nuts, and long-chain, found in fish and fish oil. In addition to the anti-inflammatory properties, the omega 3 behnics are associated with the reduction of triglyceride levels in the blood, have a protective action on the cardiovascular system and regulate the inflammatory response.
EPA and DHA mentioned in the study are the active components of omega 3, that is EPA (eicosapentaenoic acid) and the gave (docosahexaenoic acid). According to the scientific opinion of EFSA (the European Food Safety Authority), the long-chain omega 3 they play an important role in brain growth and development, blood pressure regulation, kidney function, blood clotting, and inflammatory and immunological reactions. To obtain the indicated effects of reducing blood pressure and triglyceride levels, an intake of EPA and DHA of between 2 and 4 g per day is required, while an intake of 250 mg is sufficient for the maintenance of normal cardiac function.
