A review of the role of protein and amino acids in the determination of both quantitative and qualitative aspects of food choice is discussed. The amniostatic theory of food intake regulation as a determinant of macronutrient choice is explored. To explain the effects of carbohydrates and protein on food selection and food choice the authors formulated a hypothesis based on the different effects on brain amino acids (specifically tryptophan, histidine, phenylalanine and branched-chain amino acids) intake of concentrations of these two macronutrients. The amino acids, food and selection by humans are also examined. It was concluded that the metabolism of amino acids is involved in control mechanisms regulating both quantitative and qualitative aspects of food intake.
