The author reviews the potential dietetic and clinical consequenses of long-lasting protein overfeeding. After the short description of the physiological role of proteins and the symptomes and syndromes of their deficiency, the protein metabolism of omnivorous and non-obligate carnivorous monogastrics are interpreted, including the biochemical role of amino acids. This paper examines the effect of protein excess upon the longevity, immune response and acid base balance. Relations of the main target organs (liver and kidneys) of the protein metabolism and the quantity and quality of dietary proteins are also discussed. Finally, the effect of long-lasting protein (mostly methionine) overfeeding on the tumour development is described. As a practical conclusion, the continuous protein excess is not indifferent to the health, reproduction and longevity of animals.
