I am reading Practical Paleo by Diane Sanfillipo, another tool I've discovered on my grain-free, gluten-free journey. The author provides excellent rationales for why eating wheat and grain products are bad for our health. Having followed this lifestyle for four months now, I can honestly say, I have never felt better. I feel so much healthier. I have no more physical ailments or joint pain! I can never imagine eating any other way!
