A recent study suggests that a cocktail including omega-3 could slow down the body's aging process. This comprehensive approach opens up interesting perspectives.
Scientists used a special tool to measure the effect of these changes on biological aging. This tool, called the "epigenetic clock," analyzes chemical marks on DNA to estimate the body's actual age. The results show that participants who followed this complete protocol experienced a slowdown in their aging.
The study, conducted by the University of Zurich, followed 777 people aged over 70. Researchers divided them into groups to test the effectiveness of dietary supplements and exercise. Although omega-3 alone showed positive effects, the combination with vitamin D and exercise yielded the best results.
Omega-3s are healthy fats found, for example, in fish. They help cells function better. Vitamin D, on the other hand, supports bones and the immune system. Together, these two elements form an interesting duo for slowing down aging.
Strength training is essential for maintaining strong muscles and moving more easily as we age. This research shows that combining nutrition and physical activity could be the key to aging well. Researchers now aim to test this method on other groups of people.
It should be noted that this study has some limitations. The tools used to measure biological age are not yet standardized, and the sample of participants is limited. Nevertheless, these results provide interesting leads for delaying the effects of aging.
The study was published in
Nature Aging. It marks an important advance in understanding aging and preventing age-related problems. Scientists are continuing their work to find concrete solutions applicable to everyday life.
How do epigenetic clocks measure aging?
Epigenetic clocks are scientific tools that analyze chemical modifications to DNA, such as methylation. These changes reflect an individual's biological age, often different from their chronological age.
DNA methylation is a natural process that influences gene expression. With age, methylation patterns change, allowing researchers to estimate the pace of aging. These modifications can be influenced by environmental and behavioral factors.
The most advanced epigenetic clocks, like those developed by Steve Horvath, can predict biological age with great accuracy. They have become a valuable tool for studying anti-aging interventions and understanding the mechanisms of aging.
