Protein Research Gaps Explained
- The protein RDA hasn't been updated in about 20 years because there's insufficient evidence to warrant change.
- Protein deficiency is rare, so it hasn't been a research priority compared to other health issues.
Protein and Activity for Older Adults
- Older adults should prioritize physical activity before focusing on increasing protein intake.
- Adding protein to breakfast, especially with foods like Greek yogurt, helps maintain muscle health.
Protein and Muscle Building Limits
- Muscle building benefits peak at about 0.7 grams of protein per pound of body weight, which is twice the recommended intake.
- Resistance training is essential to gain muscle; protein alone isn't enough.
