Conteúdo: | The effect of the simultaneous ingestion of soymilk and coffee on the urinary excretion of isoflavones (ISO) and chlorogenic acids (CGA) was investigated for the first time in humans. In a randomized crossover study, soy (79.7 ?mol ISO), coffee (561.2 ?mol CGA) and soy?coffee beverage (79.7 ?mol ISO and 561.2 ?mol CGA) were ingested by adult subjects (n = 6) after overnight fasting. Urinary excretion of ISO aglycones and metabolites during 48 h after soy and soy?coffee beverages consumption was 22.0 ± 19.1 and 20.3 ± 9.4 ?mol, respectively, with no difference between treatments. CGA and metabolite excretion during 24 hafter coffee and soy?coffee beverage consumption was 3.4 ± 1.2 and 3.1 ± 0.6 mmol, respectively. However, a 42% decrease in levels of CGA and primary metabolites and not of colonic metabolites was observed in urine after soy?coffee beverage consumption compared to plain coffee, indicating that substances present in soymilk, most likely proteins, bind CGA reversibly, decreasing their absorption in the digestive tract.
