Following the Diet of Older Japanese Men Can Help Slow Aging, New Study Finds

A recent study by researchers from UCLA and Japanese institutions has found that the diet of older Japanese men may significantly slow biological aging. The study involved 144 men aged 65 to 72, analyzing their dietary habits and health markers. Participants who followed a traditional Japanese diet—rich in vegetables, fruits, seaweed, and fermented soybeans (natto)—showed slower biological aging compared to those on a Western-style diet high in meat and processed foods.

The study used “epigenetic clocks” to measure biological age, considering factors like glucose levels and blood cell counts. Despite accounting for variables such as BMI, smoking, drinking, and exercise, the Japanese dietary pattern consistently showed better results in delaying aging. This finding supports the notion that diet plays a crucial role in managing the aging process and preventing chronic diseases.

The researchers emphasize that similar diets, such as the DASH and Mediterranean diets, also offer anti-aging benefits. These diets highlight the importance of consuming a variety of plant-based foods and minimizing processed foods and unhealthy fats. For those looking to incorporate these findings into their lifestyle, experimenting with traditional Japanese foods like natto and increasing the intake of vegetables and fruits can be beneficial.

This study reinforces the concept of “geroscience,” which aims to address aging and its related diseases through therapeutic and lifestyle interventions. By adopting healthier dietary habits, individuals can potentially enhance their longevity and reduce the risk of chronic illnesses. The research underscores the importance of nutrition in the ongoing quest for healthy aging and provides a compelling case for dietary adjustments as a key strategy in managing the aging process.
