high-protein

The compound adjective "high-protein" is a modern nutritional term formed by directly combining the native English adjective "high," denoting a large degree or amount, with the scientific noun "protein." The word "protein" has a conceptual journey from the Greek prōtos (first, primary), reflecting the 19th-century scientific belief that these nitrogenous substances were of primary importance to living organisms. Therefore, "high-protein" logically describes a substance where these "primary" compounds are present in a large or significant quantity, directly linking the measurable amount ("high") to the specific, essential nutrient ("protein").
