This prospective study will assess the effects of adding legumes, especially chick peas, to the diet of healthy adults on the commensal bacteria from feces of human subjects and resulting self-reported GI symptoms as well as markers of immune function.

Long-term observational study:

Subjects enrolled will participate in an observational setting for three months. During this time period, individuals will be encouraged, to maintain increased legume intake and explore new recipes that allow them to maintain a diverse menu of legume based foods. Fecal samples for microbiota analysis will be collected every month. Participants will record a weekly online questionnaire about legume intake and GI health as well as other health status updates. While participants will be encouraged to maintain regular intake of chickpeas throughout the long-term study, consumption of other legumes will be encouraged.
