[Effect of diets with excess protein on nitrogen metabolism in men].
Studies of nitrous metabolism in men aged 30-35 kept for 10 days on isocaloric rations of natural foodstuffs with excess protein content (164 and 233 g daily) have revealed unfavourable effect of increased nitrogen intake with food on the metabolic homeostasis. Even short-term consumption of excess-protein rations results in a sharp increase of urinary excretion of all nitrous metabolites and is attended by functional overstrain of the liver playing the principal role in neutralization of nitrous metabolism. Hyperazotemia and surpassed physiologic thresholds of urea and ammonia content in the blood serum are observed already when the content of protein is increased to 164 g a day in rations for men.
