Grains have fiber, yes, BUT their fiber is useless to our bodies and even promotes inflammation.

I’m gonna quote Mark Sisson, Paleo eater and author of the book “The Primal Blueprint”:

Food industry and doctors(who don’t really know nutrition at all… their area of study is medicine.) claim that: “You need the fiber!”

Okay, for one: no, I don’t. If you’re referring to its oft-touted ability to move things along in the inner sanctum, fiber has some unintended consequences. A few years back, scientists found that high-fiber foods “bang up against the cells lining the gastrointestinal tract, rupturing their outer covering” which “increases the level of lubricating mucus.” Err, that sounds positively awful. Banging and tearing? Rupturing? These are not the words I like to hear. But wait! The study’s authors say, “It’s a good thing.” Fantastic! So when all those sticks and twigs rub up against my fleshy interior and literally rupture my intestinal lining, I’ve got nothing to worry about. It’s all part of the plan, right?

Somehow, I’m not convinced that a massive daily infusion of insoluble grain fiber is all that essential. And that “lubricating mucus” sounds an awful like the mucus people with irritable bowel syndrome complain about. From personal experience I can tell you that once I completed my exodus from grains, the IBS completely stopped. If you’re not yet convinced on the fiber issue I’ll refer you to Konstantin Monastyrsky’s Fiber Menace. Anyway, there’s plenty of fiber in the vegetables and fruit I eat.

Essentially grains are utterly unnecessary in our diets when there are ready sources of carbs such as fruits, veggies, beans, etc. ready for us to eat. These are also more easily absorbed and contain tons and tons of vital nutrients. There is no reason whatsoever that humans need to consume grain foods. None.
