Protein Density 1 article

Protein density describes how concentrated a food is in protein relative to its calories, weight or serving size. Lean meats, Greek yogurt, legumes and protein powders can all score differently depending on which denominator is used, so the calculation method should be stated rather than assumed. The concept helps distinguish foods that provide substantial protein without as much accompanying energy from foods where protein is a smaller share of the total. It is a comparison tool, not a judgment of overall food quality.
