THEORY OF OBJECTS. ARTICLE 6. 4 META-COMPARTMENT: INTRACELLULAR FLUID (CYTOSOL). CYTOSOL AS AN INTERNAL METABOLIC FACTORY: PP/IT PROFILE AND RESTORATION OF INTRACELLULAR DIVERSITY IN 55+ INDIVIDUALS

Intracellular fluid (cytosol) is potentially the most diverse metabolic environment in the body, where the main reactions of energy metabolism, protein and nucleic acid synthesis, autophagy, and redox regulation take place. After the age of 55, intracellular metabolic diversity decreases dramatically: the number of documented metabolites drops from 200–300+ (potentially tens of thousands) to a critical threshold of less than 50, which is incompatible with normal cellular metabolism and is associated with mitochondrial dysfunction, accumulation of damaged proteins, sarcopenia, and neurodegeneration. However, no standard clinical analysis evaluates cytosol. The article shows how the theory of objects allows you to measure intracellular depletion, what diseases are associated with it, and how foods with a high PP/IT profile, including biogenic nutrition, restore intracellular diversity. The PP/IT profile is a format for representing two independent indices: the density of objects (PP) and the toxicity index (IT). The notation 250/11 means 250 useful molecular species and 11 harmful ones per 100 g of product — this is not a fraction, but two independent numbers side by side, like a blood pressure of 120/80. The profile is tied to the vector of product parameters: variety, origin, method of production, condition, freshness, and storage conditions. A monitoring protocol and practical recommendations for people 55+ are proposed.
