Dietary habits and longevity linked to body weight in elderly study

A study published in The American Journal of Clinical Nutrition has examined the relationship between diet and longevity in individuals over the age of 80. Analyzing data from more than 5,000 participants, researchers found that meat-eating women had a higher probability of reaching age 100 compared to vegetarian women, specifically among those with low body weight.

In underweight women, daily meat consumption was associated with a 44 percent increase in the likelihood of reaching 100 years of age. However, this correlation was not found in women with normal or higher body weights. For men, no statistically significant link was established between a vegetarian diet and the probability of reaching age 100.

The findings suggest that for the elderly, maintaining adequate energy and nutrient intake is more critical than the specific exclusion of animal products. Researchers noted that as people age, they often face muscle mass loss and decreased appetite, making protein intake and sufficient calorie consumption essential for maintaining physical strength and overall health.
