- Living longer could hinge on one surprising dietary change, study review suggests
A new study review suggests that reducing protein intake, rather than cutting calories, may improve metabolic health and longevity for sedentary adults. Lower protein consumption was linked to benefits like reduced cellular damage and improved metabolism, driven by a hormone called FGF21. The review highlights three amino acids (methionine, isoleucine, valine) that may contribute to aging-related pathways when consumed in excess by inactive individuals.
- Scientists found a longevity diet that helped mice eat more and lose fat
Scientists discovered that a modified Mediterranean-style diet low in protein and methionine improved health in mice by reducing body fat and frailty. Human data suggested lower animal protein intake correlates with reduced obesity and Type 2 diabetes rates.
- This common amino acid helped mice survive deadly inflammation
A Salk Institute study discovered that the amino acid methionine enhanced survival in mice with severe infections and inflammation by improving kidney filtration, which removes harmful inflammatory molecules. The treatment did not directly target the immune system but instead supported the body's ability to eliminate toxins causing tissue damage and other complications.
