<p>Accumulating evidence from randomized-controlled, full-feeding trials suggests neutral to beneficial effects of consuming lean and unprocessed red meat within a healthy dietary pattern on cardiovascular health. It is unclear how red meat interacts with the dietary pattern and the host in mediating its health effects. The gut microbiome provides a novel perspective in understanding the diet-host relationship for its abilities to metabolize dietary components including those within red meat and influence cardiovascular health. Prior to starting our study, we identified a lack of evidence in the English literature for the effects of consuming lean red meat, in unprocessed or processed forms, on gut microbiota in the context of a controlled healthy dietary pattern. Our findings presented in this dissertation demonstrate differential effects of consuming unprocessed versus processed red meat on gut microbiota. Consistent with previous research, we observed cardiovascular improvements induced by the healthy dietary pattern independent of lean red meat intakes among young adults with apparently healthy cardiovascular profiles. Importantly, with three intervention periods, we found consistent and reproducible changes in both gut microbiota and cardiovascular risk factors when repeatedly adopting and abandoning a healthy dietary pattern. Collectively, findings in this dissertation highlight the importance of gut microbiota in potentially mediating or responding to diet-induced cardiovascular improvements. Future research should investigate the changes in the function of gut microbiota induced by healthy dietary patterns containing red meat. Studies assessing the unique food matrix of processed versus unprocessed animal- or plant-based protein-rich foods are also warranted. Additionally, dietary strategies should focus on promoting healthy dietary modifications and enhancing dietary adherence for long-term cardiovascular benefits. </p>
