I was reading recently that the enzyme to digest fructose is produced by the tips of the villi, near the end. I already knew that the enzyme to digest lactose is produced by the very tips of the villi. What this means is that when you're on a gluten-free diet, as your villi grow back, when healing is nearly complete you may well regain the ability to digest fructose, and then when healing is complete you may regain the ability to diget lactose.

I knew about the lactose, but I didn't know that fructose was next in line right before lactose. I thought that was interesting.

Note that my source was a random person on an e-mail list that I'm on. She's a very accurate person who is always right about everything, so I didn't check up on what she was saying. But still, I'd consider this information "probably reliable but not fully confirmed."
