New Swiss research suggests that a common dietary supplement, omega-3, may slow biological aging and support longer, healthier lives. The three-year DO-HEALTH trial, published in a prestigious journal, shows omega-3’s potential benefits for older adults and for Thai readers alike.
In the randomized study, 777 participants aged 70 to 85 were assigned to daily omega-3 supplementation, vitamin D, or a combination of exercise and diet changes. The goal was to identify strategies that slow aging at the cellular level. The trial is notable for its size and its focus on real-world, accessible interventions.
Findings indicate that taking omega-3 alone was associated with a meaningful reduction in aging markers, described as a rejuvenation equivalent to three to four months. The analysis also reported a substantial reduction in cancer risk by 61% and a 39% drop in pre-frailty risk. When omega-3 was combined with vitamin D and regular resistance training, the benefits appeared even greater, pointing to a synergistic effect.
Professor Heike Bischoff-Ferrari of Basel emphasized that the DO-HEALTH trial is among the largest to demonstrate biological aging reversal signals in people aged 70 and above. She noted that simple, accessible actions could influence public health by promoting longer, healthier lives.
Medical experts outside the study highlighted omega-3’s anti-inflammatory properties as a key factor in reducing chronic disease risk. Inflammation is linked to conditions such as heart disease and cancer, which can limit both lifespan and health span.
Omega-3 fatty acids are abundant in fatty fish like salmon, tuna, and mackerel. For Thai readers considering supplementation, it is important to consult healthcare professionals to weigh personal benefits and risks within individual health profiles.
Thailand has long valued preventive health, rooted in cultural concepts of well-being and balance. Incorporating validated research into public health messaging can strengthen these traditions and support an aging population.
Looking ahead, the DO-HEALTH findings may spur broader use of dietary approaches to aging. Thai health authorities could consider integrating these insights into wellness programs to enhance healthy longevity for seniors.
Practical takeaway: maintain a balanced diet rich in omega-3 sources and couple it with regular, age-appropriate exercise. Always seek medical advice to tailor these recommendations to individual health needs.
