I've been on the paleo diet for about a year. Besides the fantastic results I've had with it, the main reason why I'm confident in it is the fact that what is known to be true in nutritional science changes all the time. Meanwhile, I'm very confident we know what our paleo ancestors ate for hundreds of thousands of years prior to the introduction of agriculture. Even if it is eventually proven that grains do not cause a problem with our diet, we should be confident that avoiding them should not be detrimental to our health given the fact that we didnt eat them for a huge span of human existence
