As students carry out their busy lifestyles, many are turning to inexpensive and convenient drink based meal-alternatives, such as Soylent, to supplement or replace their regular diets. These meal alternatives are designed to fulfill the nutritional needs of a human, but the impact on the microbiome remain unknown. This project aims to track the composition of participant's microbiome before, during, and after Soylent use to more holistically understand Soylent's impact on microbiome health.
