Description

Summary

This project will address the notion that "healthy" lipids such as monounsaturated fatty acids in almonds can be used by the bacteria living in our gut to generate "new" molecules with potentially interesting health properties. This metabolite pattern is anticipated to differ significantly when compared to non-almond foods rich in saturated fats.
