Per one of the leading experts, Michelle Petri, MD, at Hopkins, garlic is a trigger. There's no standard diet for lupus per se, but a Mediterranean or whole-food plant-based diet is suggested. Some experts believe plant-based is the least inflammatory, partly because dairy contains casein, an inflammatory protein. I and others have written more about this. Some of us, including me, have found a vegan diet helpful, and some have even gone into remission on it.

Best wishes to your daughter!
