[Controversies around diet proteins].
Critical theories regarding proteins of anima origin are still and still popularized, though they are ungrounded from scientific point of view. Predominance of soya proteins over the animal ones in relation to their influence on calcium metabolism, bone break risk or risk of osteoporosis morbidity has not been confirmed in any honest, reliable research experiment. Statement, that sulphur amino acids influence disadvantageously on calcium metabolism of human organism and bone status, is completely groundless, the more so as presence of sulphur amino acids in diet (animal proteins are their best source) is the condition of endogenic synthesis of glutathione, the key antioxidant of the organism, and taurine stimulating brain functioning. Deficiency of proteins in the diet produce weakness of intellectual effectiveness and immune response. There is no doubt that limitation of consumption of animal proteins of standard value is not good for health.
