The researchers are going this to look at how butyrate levels change in participants' stool after they are on a plant-based diet or dietary supplements (omega-3, curcumin or probiotics) for 2 weeks. All participants will have smoldering multiple myeloma (SMM) or monoclonal gammopathy of undetermined significance (MGUS). The researchers will compare how the different dietary changes affect butyrate levels in participants' stool.
Confirmed prior diagnosis MGUS or of smoldering myeloma (any time prior). However, confirmation of diagnosis must be documented in their last local oncologist clinic note within 6 months prior to study enrollment.
Age ≥18 years

Taking any supplements other than vitamin D, iron, vitamin B12, potassium, magnesium, calcium or those needed for a medical indication must be reviewed by PI. If patient is on a supplement (including curcumin, probiotic, omega3) they must stop these for 2 weeks prior to enrollment on study.
