Lower Protein Intake Linked to Healthy Aging in Adults, Study Suggests
Researchers reviewed more than 350 studies and found low-protein diets may improve metabolic health and, in some cases, extend lifespan.
- A review of more than 350 studies published in Cell Press Blue suggested that reducing protein intake may slow aging and improve metabolic health, particularly for sedentary adults.
- Current U.S. dietary guidelines, updated this year by Secretary of Health Robert F. Kennedy Jr., recommend 1.2 to 1.6 grams of protein per kilogram of body weight, nearly doubling the previous target of 0.8 grams.
- The hormone FGF21, which rises when protein intake is low, helps convert white fat cells into energy-burning beige fat cells, improving blood sugar control and reducing inflammation according to researchers.
- Active individuals may be protected from high protein's downsides because exercise directs amino acids into muscle growth, University of Wisconsin-Madison biologist Dudley Lamming notes, suggesting recommendations should be personalized by activity level.
- Nutritionist Joseph Matthews of the University of Arkansas for Medical Sciences emphasizes that "what we need is a handful of high-quality human studies," noting that translating animal findings to humans remains debatable.
