Barrett's belly was very bloated tonight. I could tell without measuring but I measured anyway. Around his belly button he was 21 1/2 inches (normally 18 1/2). He has just been complaining that his stomach hurts as well. So far he hasn't had any other symptoms but we'll be watching him.
Foods he ate today:
buckwheat cereal in rice milk, banana, homemade zucchini bread, mixed nuts, quinoa cooked in chicken broth with organic ketchup, pineapple, apple, orange, Baked Lays Natural potato chips, black beans
I'll update if and when more symptoms show up.
ETA. I just read the label of the chicken broth I used. It was Swanson Natural Goodness Chicken Broth. It claims to have no MSG. However, the label says it has autolyzed yeast extract (oops, I was supposed to be avoiding yeast anyway). It could be the yeast that made him bloat, but he has never bloated from the yeast in the tapioca bread he used to eat. In fact, I have never seen him react to yeast. However, this website mentions that a different variation of Swanson broth states that the yeast extract comes from wheat. This article talks about manufacturers hiding MSG under the name of autolyzed yeast extract which is used to make MSG (wikipedia:yeast extract). MSG is something that should generally be avoided because it often is derived from wheat--and many people who react to gluten react to MSG anyway.
