Simple Daily Habit Slows Biological Aging in Middle-Aged Men, Study Finds

A groundbreaking study published in the journal Aging reveals that simple lifestyle changes can significantly slow biological aging. Conducted over 12 weeks in Japan, the clinical trial involved 48 overweight men aged 50 to 74 who adopted a structured health routine. This routine included daily consumption of 100 grams of probiotic yogurt, personalized nutritional counseling to avoid overeating and sugary drinks, and moderate physical activity such as walking or stair climbing for 30 minutes at least three times a week.

Researchers measured the biological aging rate using the DunedinPACE tool, which assesses cellular aging speed rather than chronological age. The intervention group showed an average 2.2% reduction in biological aging rate compared to a control group that maintained their usual habits. Notably, this improvement occurred independently of weight loss or exact exercise amounts. Additionally, a specific DNA marker related to kidney function improved.

The study emphasizes that the benefits stem from the combined effect of diet and exercise rather than any single factor like yogurt alone. The 2.2% reduction in aging speed over three months is comparable to a 25% calorie reduction sustained for two years in previous research. However, the authors caution that the sample size was small, short-term, and limited to overweight men of one nationality, calling for further studies to confirm long-term health impacts.

Overall, the findings scientifically support that accessible daily habits involving probiotics, balanced nutrition, and regular movement can positively influence cellular aging and promote long-term health maintenance.
