I am a vegetarian. I want to say vegan, because I don't eat eggs, but I do eat and drink diary products. Besides not eating that I also can't eat bread and pasta, because it makes my stomach feel uncomfortable then I end up feeling nauseated and sometimes I puke. This also happens when I eat food with curry in. I do have i. B. S and gastritis. Besides not being able to eat those foods lately it feels like its starting to happen with more and more foods, I dread having to decide what to eat. It feels like I can't make up my mind because to me food doesn't taste nice. The only things I can eat without feeling like this is potatoes tomatoes green beans dairy products and carrots. That is about it. I decided to try out a vegan meal replacement, but is that healthy to only eat the foods that I mentioned above combined with the vegan meal replacement? Also if I had an allergic reaction to the iodine injected during a cat scan does that mean i'm also allergic to iodine in the meal replacements? All the meal replacements have iodine in and i'm not sure if I will get an allergic reaction? Please help, because i'm always feeling tired and weak because I do not have enough vitamins in my body.
