New Research Explores the Link Between Meat and Female Longevity
A recent study by Chinese researchers reveals that underweight women who consume meat daily are 44% more likely to live to 100 compared to those on a vegetarian diet. The same association was not observed in men. Published in Science Alert on May 22, 2026, the study highlights a statistical correlation, not a proven cause-and-effect relationship.
The research analyzed data from over 5,000 individuals who had reached the age of 80. This comes at a time when the global population aged over 80 is projected to approach nearly 500 million by 2050, making dietary impacts on longevity an increasingly urgent topic.
Comparing Health Outcomes Across Age Groups
Scientists compared the health profiles of 1,459 centenarians with 3,744 people aged 80 to 90. Among women who ate meat, the likelihood of reaching 100 was higher than among vegetarian women. However, lower odds of living to 100 were only observed in underweight vegetarians. No such link was found for individuals with normal or overweight body types.
Interestingly, vegetarians who included fish, eggs, or dairy in their diets had roughly the same chances of reaching 100 as meat-eaters. Some estimates suggest that healthy habits account for about 70% of the likelihood of living to 90. These findings open new avenues for understanding the factors that influence extreme longevity.
The study underscores the role of dietary habits in health and longevity, particularly for underweight women.
As the world’s population ages, these results could shape future nutritional guidelines and healthy lifestyle recommendations, ultimately helping to improve the quality of life for older adults. Exploring these connections is a critical step toward developing strategies for extending active, healthy years in old age.
