Well, for someone with a Ph.D. in human nutrition and a postdoc in developmental immunology, the relationship between "refined sugar" (sucrose, glucose, dextrose, fructose ???) and "immune suppression" (T-dependent, independent, complement-mediated, Th1, Th2 ???) is a new one on me. I would LOVE to see the references. In any case, I would advise against attributing mastitis to a diet containing a high proportion of "refined sugar." ------------------------------------------- J.
