<<Disclaimer: Verify this information before applying it to your situation.>> I thought amaranth flour had gluten, but evidently I'm mistaken. Any ideas on how to gain weight when you are gluten, fructose intolerant, sensitive to some aspect of milk and I think fats and possibly eggs are bothering. Do you know that everything has sugar in it. I was just told yesterday that I am fructose intolerant. I have not yet become educated to this new kink in my life but they did tell me no more fruits! That's what I lived on at lunch time and no fruit juice--can you imagine. What can I eat to gain weight--down to 89 and just keep losing--any suggestions?
