A lot of information is coming to light on how difficult it is for the body to digest grains. Most contain gluten or mycotoxins — both inflammation-causing villians that are associated with leaky gut syndrome and many auto-immune disorders.
Dr. Loren Cordain, a professor at Colorado State University and an expert on Paleolithic lifestyles, humans are NOT designed to eat grains, and doing so may actually be damaging to your gut. For more details, I recommend that you read Dr. Mercola’s article and do some further research online.
The Paleo (aka Caveman’s) Diet rejects most grains because of these issues. I covered this topic briefly in a former blog called A Pinch of Paleo; Bread enthusiasts can get their “fix” with some non-grain recipes included in that article.
