IMHO, you are fortunate to have found a link between a certain food and your diarrhea. I wish I could find a link to mine. If I knew what caused it, I would avoid that food completely. Why don't you want to avoid fat? You could take Omega 3 or fish oil to make up for lacking fat in your diet.

You might have Gallstones if you are sensitive to fatty foods. Try taking some choline and some selenium in Horsetail herb capsules. Might want to have a hot cup of lemon juice water first thing in the morning. Check out the "liver flush" forum and do your homework before you get worse. I had my gallbladder out and I still make Gallstones in my liver...not fun. God bless.
