Abstract
A large number of acidic foods is formed in the human body during the metabolism during the day. The main products of metabolism in the cell are acids that dissociate with the release of [H+] ions, but due to buffer systems, acidification of the intracellular medium does not occur. As a result of oxidative processes, volatile carbonic acid and non-volatile acids are formed in tissues, such as sulfuric acid (during the cleavage of methionine and cystine), uric acid (during the cleavage of nucleoproteins), free fatty acids of various molecular weights, as well as inorganic phosphates. During the day, up to 2-3 liters of hydrochloric acid are formed in the gastric mucosa.
Maintaining the constancy of the pH of the blood, interstitial and cellular sectors is ensured by buffer systems that maintain the pH at the optimal level for the function of organs and tissues
