Protein Consumption Guidance Reassessed Amid Overdose Concerns

A review of more than 350 studies published in Cell Press Blue finds that reducing protein intake, rather than increasing it, can extend lifespan and lower age‑related disease risk. The authors, led by Dudley Lamming of the University of Wisconsin‑Madison, warn that many sedentary adults consume more protein than needed, especially after recent U.S. dietary guidelines doubled the recommended daily allowance.

The same "protein mania" has spread to Italy, where supermarkets now stock a wide range of fortified foods—yogurt, bread, pasta, coffee and even water—labelled as high‑protein. Consumer interest has also driven growth in plant‑based protein powders. A guide for Italian shoppers highlights the need to compare ingredient lists, protein sources (such as pea, rice or soy), and environmental impact, noting that product quality varies widely.

Both pieces suggest that while adequate protein remains essential for muscle maintenance, especially in active individuals, most people would benefit from moderating intake and considering plant‑based alternatives.
