Question: what are grams of protein?
Answer: In nutrition science, "grams of protein" refers to grams of the macronutrient protein, not grams of a protein-containing food like meat or eggs. An 8-ounce serving of beef weighs 226 grams but only contains 61 grams of actual protein. Similarly, a large egg weighs 46 grams but only packs 6 grams of protein.
