Summary

In plain language

Researchers studied the effects of a special diet on biological aging in men aged 50 to 72. This diet included foods like green tea, berries, and turmeric, while avoiding sugar, alcohol, and dairy. The study found that men who followed this diet were able to reduce their biological age by an average of 2.04 years, compared to those who did not change their diet and saw an increase of about 1.10 years. This suggests that what you eat can influence how quickly or slowly your body ages, which is important for maintaining health as you get older.

Details

Use the full description to understand the study design, methods, and the limits of the findings.

The study involved 43 men between the ages of 50 and 72. Researchers divided them into two groups: one followed a diet rich in plant-based foods, and the other continued their usual eating habits. Over eight weeks, the intervention group was instructed to include foods known as 'methyl adaptogens' and practice daily meditation and exercise.

  • The men who followed the diet reduced their biological age by 2.04 years, while the control group increased by 1.10 years, creating a 3.14-year difference between the groups.

  • While the study showed promising results, there was variability in how individuals responded, indicating that diet might not be the only factor at play.

  • This research suggests practical dietary changes can support healthier aging. Discuss these findings with your healthcare provider to see if such dietary changes could benefit you.

Research Quality Score

Scored September 28, 2026 using rubric mq-1.8_2026-07-06.

Assessment

The study scored well in study design due to its RCT basis, but lacked full bias control due to unreported blinding. Statistical methods were standard but lacked power analysis. Transparency was partial, with registration but incomplete data sharing. Conflicts were well-managed with public funding. No replication was cited, and journal quality was unassessable. The study was highly relevant to the target population.

Additional Notes

The study is a secondary analysis of a randomized controlled trial examining the impact of dietary components on epigenetic age in men aged 50-72. It found that foods categorized as methyl adaptogens were associated with reductions in epigenetic age.

Assessed on the study's full text across 8 quality dimensions; conflict-of-interest disclosures were reviewed.
