Excess protein consumption offers limited health benefits, experts warn

The food industry has heavily promoted protein, labeling many products such as bars, yogurts, cereals, drinks and desserts as "high‑protein" and suggesting that more protein is always better. Nutrition experts caution that most people with a balanced diet already meet their daily protein needs without supplements or fortified foods.

Higher protein intake does not automatically increase muscle mass; muscle growth depends on strength training, adequate rest and sufficient—not excessive—protein. Consuming excess protein, especially from ultra‑processed fortified products, can displace other essential nutrients and may add sugars, saturated fats, sodium or additives. Only groups such as high‑performance athletes, older adults, or individuals recovering from illness may require higher amounts, and this should be assessed by health professionals. Experts recommend obtaining protein from natural sources like fish, eggs, dairy, lean meat, legumes, nuts and seeds, and focusing on a varied, balanced diet rather than chasing protein‑rich marketing claims.
