In 2015 there were over 30 million Americans with diabetes and over 84 million Americans ages 18 and older had pre-diabetes. With diabetes being the seventh leading cause of death in the United States and becoming more prevalent the race is on to find a cure. One of the main problems with this disease is the decrease in functional β-cell mass. β-cells produce insulin to maintain blood glucose levels at healthy levels. Thus, if we can increase β-cell proliferation we are one step closer to curing diabetes. Cocoa epicatechins have been shown to be beneficial in blocking diabetes progression. Studies have shown that oligomeric and polymeric cocoa epicatechin extracts improve diabetes onset in a mouse model of Type 2 diabetes. We have demonstrated that the oligomeric fraction of cocoa epicatechins enhances β-cell proliferation in an in vitro model. Absorption studies have shown that while the oligomeric and polymeric forms are not readily absorbed in the gut, they are metabolized by gut bacteria and that these metabolites can be observed in circulation. Using flow cytometry we have studied how these phytochemicals: epicatechin, 5-phenylvaleric acid, Homovanilic acid, and Hippuric acid. Here we present the data regarding the effect of microbial cocoa flavanol metabolites on β-cell cell cycle during proliferation.
