A new study points to omega-3 fatty acids as a potential tool to support longevity and overall health in seniors. The DO-HEALTH trial, conducted in Switzerland, explored whether daily omega-3 intake could slow biological aging in adults aged 70 to 85. Participants received a 1-gram omega-3 supplement daily alongside vitamin D, while others followed an at-home exercise program.
Over three years, researchers found that those taking omega-3 showed slower progression of aging markers. The results suggested a rejuvenation effect of about three to four months. Additionally, the data indicated a reduced risk of cancer by about 61 percent and a lower chance of pre-frailty by 39 percent—conditions that often precede frailty in later life.
Lead researchers from a Basel collaboration emphasize the novelty and potential public health impact. According to the study team, DO-HEALTH demonstrates, for the first time, that aging can be modestly reversed through simple interventions like dietary supplements and physical activity. The researchers note that combining omega-3 intake with vitamin D and regular strength training may offer enhanced protection against early frailty and cancer.
Independent experts echo the enthusiasm. A senior medical analyst highlights omega-3’s antioxidant and anti-inflammatory properties as key to mitigating chronic diseases such as heart disease and high cholesterol, which can influence both healthspan and lifespan.
For Thai readers, the findings reinforce the value of omega-3-rich foods—especially fatty fish like salmon, tuna, and mackerel—alongside a balanced lifestyle. Before making changes to diet or supplements, readers should consult healthcare professionals to discuss personal risks and benefits.
In Thailand, traditional diets have long benefited from fish consumption, though modern dietary shifts toward processed foods may reduce omega-3 intake. The DO-HEALTH results suggest that maintaining or reintroducing omega-3 sources could support healthy aging in the Thai context, where aging trends are notable in the region.
Looking ahead, healthcare providers may increasingly consider omega-3 as part of a broader strategy to promote healthy aging, particularly for the growing elderly population in Thailand. Practical steps include prioritizing fatty fish in meals, mindful supplementation where appropriate, and continued emphasis on regular, guided physical activity.
