Protein Guidelines Under Scrutiny: Evidence Gaps at Heart of 2025–2030 Recommendations

TL;DR Summary
A Perspective published in The Journal of Nutrition analyzes the updated 2025–2030 Dietary Guidelines' protein recommendation of 1.2–1.6 g/kg/day. It acknowledges strengths such as a focus on high‑quality protein and potential weight‑management benefits for those with overweight/obesity, but argues the current evidence does not justify a universal higher‑protein intake for all Americans and calls for more diverse research across life stages and populations to strengthen future guidance.
