Protein Questions Worth Asking

From the diet.do library · Educational information, not personal medical advice.

Protein comes from fish, meat, eggs, dairy, soy, beans, lentils, nuts, seeds, and combinations of plant foods. Your needs vary with age, body size, activity, and medical circumstances.

The 30-gram claim

The idea that protein above a fixed amount in one meal is simply wasted is too crude. A controlled human study found that a larger protein dose after exercise led to a larger and longer anabolic response than a smaller dose. That does not mean everyone should eat very large protein meals.

The practical version

Include a protein source in meals you enjoy. If you are training hard, older, pregnant, or living with kidney disease, individualized advice matters more than a social-media target.
