Jakarta, ThedailyID — Eating meat may be linked to a higher chance of living to 100, especially among underweight older women. A study published in The American Journal of Clinical Nutrition in February 2026 found this association.
Researchers in China, led by Yaqi Li, analyzed data from more than 5,000 people aged 80 and older. They found that women who ate meat had a higher likelihood of reaching 100 than women who followed vegetarian diets.
However, the researchers found no significant link between vegetarian diets and longevity among men. Body weight also appeared to affect the results.
Among underweight participants, daily meat consumption was linked to a 44% higher likelihood of reaching 100 compared with a vegetarian diet. The researchers found no similar link among people with normal weight or those who were overweight.
The study also highlighted differences in vegetarian diets. Some vegetarians still eat fish, eggs, and dairy products, which provide alternative protein sources. These participants had similar chances of reaching 100 as meat eaters.
The findings suggest that older women may benefit from getting enough calories and essential nutrients. However, the study does not prove that eating meat directly extends life.
Other factors may also affect the results. For example, older adults may change their diets because they struggle to chew certain foods. These changes can limit their food choices and affect their nutritional intake.
Beyond diet, healthy habits remain important for aging well. The US National Institute on Aging recommends staying physically active, maintaining social connections, eating a balanced diet, and getting regular health checkups.
Ultimately, no single food guarantees a longer life. The study points to a possible link between meat consumption and longevity among underweight older women, while highlighting the importance of adequate nutrition and overall health.
