Abstract
The human gut microbiome plays a fundamental role in physiological processes and homeostatic relationships in the body, with research proving its effects beyond gastrointestinal functioning such as in immune response, psychological operation, and nutritional metabolism. Caffeine, nicotine, and theobromine—the principal bioactive compounds in regularly consumed products like coffee, cigarettes, and dark chocolate, respectively—may yield significant and variable influences on human health beyond their normal pharmacodynamics through affecting gut microbiota. Using metagenomic modelling, predictions can be determined regarding intestinal community activity as well. I hypothesize that the compounds will alter microbial community composition in a time- and dose-dependent manner.
