Fish-Eaters and Vegetarians Show Slower Biological Aging Than Regular Meat-Eaters
Among over 400,000 UK adults, people who ate fish but little meat aged the slowest biologically. Vegetarians came in a close second. Regular meat-eaters aged fastest by two different biological age measures. These patterns held up over time too. People who stuck with low-meat, fish-based, or vegetarian diets saw their biological aging slow down compared to consistent meat-eaters during follow-up.
Kernaussage
This study suggests reducing meat and including fish may be linked to slower biological aging.

Tracking Your 'Biological Age' Over Time May Predict Death Risk Better Than a Single Snapshot
In over 90,000 Dutch adults followed for nearly 14 years, people whose biological age ran ahead of their calendar age had a higher risk of dying. More importantly, among 25,000 people measured twice, those whose biological age sped up over time faced even greater risk. People stuck in a pattern of accelerated aging had a 39% higher mortality risk compared to those aging at a normal pace. The results suggest that checking biological age once might not be enough.
Faster Biological Aging Linked to Worsening Brain Small Vessel Disease
People who age faster biologically (based on blood biomarkers) appear more likely to develop worsening brain small vessel disease. In roughly 3,000 middle-aged adults followed for about five years, those with higher biological age scores had more new tiny brain lesions like lacunes and microbleeds. This held true even after accounting for actual calendar age. The finding suggests that biological aging clocks could help flag people at risk for this common precursor to dementia and stroke.
Eating More Fruits, Fish, Nuts, and Dairy Tied to Slower Cognitive Decline
In over 3,000 Chinese older adults tracked for about five years, those who ate more from six protective food groups (fruits, vegetables, nuts, legumes, fish, and dairy) showed slower cognitive decline. People scoring highest on this diet scale declined about 0.42 points per year slower on a cognitive test compared to those scoring lowest. The effect was modest but consistent across different ways of measuring cognition.
