Fish-Eaters and Vegetarians Show Slower Biological Aging Than Regular Meat-Eaters
Graded Moderate — population cohort of 407,376 adults, with the longitudinal analysis limited to 8,855 and dietary patterns observed rather than assigned, so causation is not shown.

This study suggests reducing meat and including fish may be linked to slower biological aging.
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.
