Purpose
The purpose of this study is to assess whether a tailored diet, eliminating antigens to which IgA nephropathy patients have demonstrated sensitivity, will have an effect on proteinuria, renal function and other immunological variables.

| IGA Nephropathy | Dietary Supplement: Tailored diet Dietary Supplement: Low antigen content diet |
| Study Type: | Interventional |
| Study Design: | Allocation: Non-Randomized Intervention Model: Parallel Assignment Masking: None (Open Label) Primary Purpose: Treatment |
| Official Title: | A Pilot Study of 6 Months Diet Intervention in Food Sensitive Patients With IgA Nephropathy |
