She eats a lot of peanut butter, yogurt and cheese . Unfortunately that doesn't help you. Beans are good sources of protein. She certainly has an interesting medical history and for the most part is healthy but still has some lingering issues, mostly D and migraines now so I'm thinking that Celiacs might be the last piece to the puzzle. I'm actually really surprised she has not been tested already with everything else she has going on.
It took me 20 years to get them to test for celiac...so, I get that one! I used to have major issues with headaches as well, and they have gone away 100%. The D though...that's the battle! I love yogurt and cheese...could totally live on that!!!
