Hey Lefthanded, you asked who can't eat blueberries or lettuce? Me. Because I have Porphyria. It has nothing to do with roughage in my case. It has to do with the chemicals in those foods. Lettuce and all cruciferous veggies are high in sulfur. I am not sure what
blueberry's problems are, maybe sulfur. I can eat other berries, especially blackberries.

I have been on the Swank diet for over a generation, so long I forget what was the start date--I know it was within weeks of dx of MS. The only main modification is that I often
eat two eggs for breakfast. Swank allowed only two a week. I have always gotten on well with eggs, even when I was pregnant and could eat only eggs and oranges during the fourth month.

Right now I am feeling that healthy people should eat more fat, i.e., more than the organic canola and olive oils that I eat--a health site recommends organic butter, but of
course that is not on Swank. Swank felt we had autoimmune reactions to fat, which attack myelin. He was one of my physicians, a wonderful man.

Because I have porphyria I also cannot tolerate Aspartame and Sweeta. I knew that long before dx.
