Our bodies are home to tens of trillions of bacteria. These microbes primarily inhabit our skin, mouth, and gut. Previous studies have shown that Western diets high in fat and sugar can have an impact on the variety and composition of the gut microbiome, and such studies have been repeatable. However, the effects of Western dietary patterns in conjunction with carboxymethyl lysine (CML, a cooked food byproduct associated with increased cardiovascular disease) on the gut microbiome have not been specifically investigated. We used the Total Western Diet (TWD) in order to observe these changes in mice; this diet reflects approximately the 50th percentile of daily macro and micronutrient intakes in Americans.
We hypothesized that the gut microbiome of mice fed TWD containing various levels of CML would differ from those fed TWD with no CML. We further hypothesized that these changes would be dependent on the dietary CML concentration. The experimental diets were as follows: TWD containing no cooked protein or fat (no CML), TWD containing 20% cooked protein and fat (low CML), and TWD containing 40% cooked protein and fat (high CML).
After a twelve-week feeding period, fecal samples were collected from each of each of the three diet groups. Bacterial DNA was then extracted from fecal samples and analyzed for bacterial composition by 16s genetic sequencing. The effect of experimental diets on gut microbiome taxonomy, alpha diversity, and beta diversity will be presented.
