> Intestinal flora is something the medical community is just now beginning to research and understand.

What's interesting is that intestinal flora can take time to adjust in response to dietary changes (wish I could find some good figures on precisely how long, but the whole field of research on the subject is so new). This means that those on a seemingly unhealthy diet can initially do far worse switching over to 'unfamiliar' healthy food as their gut flora are presented with something they have little 'experience' digesting.

In my own experience, cutting out grains and milk from my diet resulted in a good few months of problems before things settled down again which seemed very counter intuitive until I read up on the significant role gut bacteria play in digestion.

I know when I started eating paleo, I had really painful gas (to me and everyone else) for a few months. Then, after a while, I could eat all the broccoli I could stand and it was fine.
