New study: Meat consumption linked to longevity, but with one condition

An observational study from China found a statistical link between meat consumption and longevity among older women, but only among those who are underweight. The researchers emphasize that this is a statistical correlation that does not prove causation, and that overall diet and prevention of malnutrition are the decisive factors.

A new observational study from China, based on data from over 5,000 people aged 80 and older, found a statistical link between meat consumption and a higher chance of reaching age 100 among older women. However, the link existed only in a specific group: women classified as underweight. Among women of normal weight or overweight, no significant difference was found between meat eaters and vegetarians. The researchers suggest that the decisive factor is not the meat itself, but adequate calorie and protein intake, essential for maintaining muscle mass in old age. It was also found that vegetarians who included fish, eggs, or dairy products had a similar chance of reaching age 100 as meat eaters. The researchers emphasize that this is an observational study that does not prove causation, and that other lifestyle factors may have influenced the results. The main conclusion is the critical importance of preventing underweight and malnutrition among the elderly, and maintaining a balanced diet that includes both animal and plant foods.
