THEORY OF OBJECTS. ARTICLE 11. 9 META-COMPARTMENT: BILE. BILE AS A HEPATOBILIARY META-COMPARTMENT: PP/IT PROFILE AND RESTORATION OF METABOLIC DIVERSITY IN PEOPLE 55+

Bile is a hepatobiliary metacompartment containing bile salts, cholesterol, bilirubin, phospholipids, and their metabolic products, which are critical for the digestion of fats, the absorption of fat-soluble vitamins, and signaling. After the age of 55, the metabolomic diversity of bile decreases sharply: the number of detected metabolites drops from ~1100 to a critical threshold of less than 300, which is associated with cholestasis, cholelithiasis, nonalcoholic fatty liver disease, metabolic syndrome, and colorectal cancer. However, standard clinical analyses assess only a narrow set of bile parameters and do not reflect metabolomic diversity. The article shows how the theory of objects can measure the metabolic depletion of bile, what diseases are associated with it, and how foods with a high PP/IT profile, including biogenic nutrition, restore metabolomic diversity. The PP/IT profile is a format for representing two independent indices: the density of objects (PP) and the toxicity index (IT). The entry 250/8 means 250 beneficial molecular species and 8 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.
