i am have some some issues with gas, not so serious but still. I am now trying single-ingredient diet. I see some people are doing it on internet but they are vegans. I was thinking about eating one type of fruit for a meal, then let's say potatoes, and then some cheese or eggs alone, or meat alone. I guess, I would add fat to potatoes or perhaps some honey to white cheese. But you get my point. There are many theories about food combining, but most of them are questionable. Eating one food at the time makes more sense from digestion perspective so all the different foods do not get mixed in the stomach and begin to ferment.
