A new study found that a modified Mediterranean-style diet low in protein and containing moderate amounts of the amino acid methionine helped mice eat more while reducing body fat, frailty, and age-related health decline. Researchers also observed that people who consumed less animal protein had lower rates of obesity and type 2 diabetes, suggesting similar dietary patterns may support healthier aging.

For now, a balanced, nutrient-rich diet remains the best-supported strategy for healthy aging.
