Study finds vegetarians over 80 less likely to reach 100

"Researchers followed more than 5,000 adults in China who were age 80 or older and enrolled in the Chinese Longitudinal Healthy Longevity Survey, a nationally representative project that began in 1998. By 2018, participants who did not eat meat were less likely to become centenarians compared with those who consumed meat."

"As people age, the body goes through significant physiological changes. Energy expenditure decreases, and losses in muscle mass, bone density, and appetite are common. Together, these changes increase the risk of malnutrition and frailty."

"Most evidence for the health benefits of diets that exclude meat comes from studies of younger adults rather than frail older populations. Some research suggests older non-meat eaters face a higher risk of fractures due to lower calcium and protein intake."

A study of over 5,000 Chinese adults aged 80 and older found that non-meat eaters were less likely to become centenarians than meat consumers. This finding appears to contradict decades of research showing plant-based diets reduce risks of heart disease, stroke, diabetes, and obesity in younger populations. However, the results reflect fundamental differences in nutritional needs for the very elderly. As people age, physiological changes including decreased energy expenditure, muscle loss, bone density decline, and reduced appetite increase malnutrition and frailty risks. Nutritional priorities shift significantly in advanced age, where adequate protein and key nutrients become more important than strict adherence to plant-based eating patterns.
