Protein Guidance Fight Intensifies as U.S. Push for Higher, Animal-Focused Targets Meets Expert Caution

Overview

• O Globo reported a newly publicized U.S. dietary pyramid calling for 1.2–1.6 g/kg of protein per day with an emphasis on animal sources, a shift it attributes to MAHA-linked bodies.
• Recent evidence cited in the coverage supports smaller increases: about 1.0 g/kg/day for healthy adults, 1.2–1.5 g/kg for athletes, and 1.0–1.5 g/kg for older adults.
• Large observational studies associate higher plant-protein patterns with lower all-cause and cardiovascular mortality, while higher animal-protein patterns correlate with increased risks of type 2 diabetes, cardiovascular disease and some cancers.
• Practical guidance highlights accessible options for those over 50, including eggs, yogurt and microalgae, alongside plant-forward staples such as rice and beans that together provide complete amino acids.
• A G1 podcast underscores rapid market growth—estimated at $55 billion in 2024 with projections near $130 billion in a decade—and features warnings about unnecessary or excessive protein consumption.
