I have recently personally learned that there may be many shades of grey between "no problem" and "celiac".

I had stopped eating wheat, not because of suspecting gluten intolerance, but because I wanted to hold back on fast carbohydrates.

After 4 months I tried eating some bread sporadically (as I'm nearing my ideal weight), and on another day some whole wheat pasta. I was amazed at how difficult it seems for my body to process the wheat. Immediately I felt slightly bloated after eating one piece of bread, and in both cases I felt hungry again after 3 hours, where I got used to not getting hungry at all for up to 8 hours after a meal.

My wife - who first reluctantly followed my diet, but is now over the moon with it - had exactly the same reaction.

I'm not talking about a severe reaction: just slightly uncomfortable, a feeling of having eaten too much (we hadn't). That feeling lingered for quite a long time.

It may be anecdotal, and I suppose it's still speculation, but it just might be that our bodies aren't really made to eat wheat (especially refined forms). I was really surprised, as I always loved whole wheat bread (fresh from the bakery here), and considered it healthy. At this point I don't think I will introduce it into my diet again, as I want to avoid eating anything that upsets my digestion and/or my PN.
