I notice that whenever i eat some fruit, honey, maple syrup or other high fructose foods i get anxious, moody and bloated. This never happens with glucose containing carbs like white rice, yuca, sweet potatoes and yams, just fructose carbs. Could this be fructose malabsorption?
It sounds like it probably is. If you want a definitive diagnosis, your gp can perform a simple, noninvasive test in his office. If you just want to do your own experimenting at home, it sounds like you know where to start adjusting.
A lot of people do say that they respond differently to fructose and glucose. I recently wrote a blog post on the difference over at paleoisms.wordpress.com, but it's certainly possible that you have a deficiency in fructose metabolism.
