Yes, but cows agree with my innards. That could be solved by getting rid of freedom food and growing cows in pitch black pods and electrocuting them to build muscle mass and harvesting their poo for energy.

As for adapting, I'm not sure if that is true. I used to eat curry and my body changed to not agree with hot ones. I didn't adapt to that. I also used to love salads full of spinach and onions and other bowel storm inducing veg and now I can't eat that! I don't think the human digestive tract is designed to break down so much fibre, otherwise we'd be chewing on hessian sacks instead of gum.
