Lower Protein Intake Linked to Healthy Aging in Adults, Study Suggests
The review of more than 350 studies says lower protein intake can improve metabolic health and cellular repair, while human lifespan benefits remain unproven.
- 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.

You need less protein than you think, study suggests
Emerging evidence supports that while protein benefits active people by aiding muscle growth, excessive protein for inactive individuals could harm health. Personalized protein guidelines considering an individual’s activity and age are key for maximizing benefits and reducing potential metabolic risk.
It is one of the biggest global health trends of the moment: consuming as much protein as possible. But a new study conducted by the University of Wisconsin-Madison in the United States shows that eating less protein may actually be the key to a long and healthy life, writes Euronews.
