When it comes to protein, quantity is not enough; protein quality must also be considered. We propose a model for determining the protein quality of foods. We define a food’s protein quality as a function of the indispensable amino acids (IAAs) composition of the protein content in the food.
Part 1 analyzes foods for their protein quality relative to our selected gold-standard food, which governs a food’s IAA Quality Scores. We explain why eating higher protein quality foods can be protective against overeating and can help to prevent unwanted weight gain.
