In the paleo community, gas is something to be avoided. Why? Gas generally results from incomplete absorption of certain nutrients, especially including carbohydrate, resulting in its being used by gut bacteria with the concomitant generation of gas.
Grain consumption, especially wheat, is very much associated with the "leaky gut syndrome," and Candida yeast.
Here is a really good question that I haven't asked before and I don't think you could argue: If grains are so healthy, why are they so high on the inflammation scales?
