A recent study from China has revealed interesting findings about how diet may influence longevity in older adults. Researchers analyzed data from more than 5,000 people over the age of 80 and found that underweight elderly women who eat meat daily may have a higher chance of living to 100 years old compared to those following a vegetarian diet.
The study noted that this connection was not observed in people with normal or higher body weight, suggesting that body weight may play an important role in healthy aging. Researchers also found no major differences in longevity among vegetarians who consume eggs, dairy products, or fish when compared to regular meat eaters.
Health experts explained that low calorie and protein intake in older adults could negatively affect overall health and increase the risk of long-term health issues. However, they emphasized that the study only shows a statistical association and does not prove a direct cause-and-effect relationship.
The researchers also pointed out that other important factors — such as physical activity, lifestyle habits, and dietary changes throughout life — were not fully considered, meaning the findings should be interpreted carefully.
In conclusion, the study suggests that a balanced diet containing both plant-based and animal-based foods in moderate amounts may be more supportive of healthy aging. The research was published in the scientific journal American Journal of Clinical Nutrition.
