I have a theory about the rise in celiac disease and other food sensitivities. I believe the escalation started with the introduction of commercial breads and other baked goods in the 1950′s and continues on with genetically-modified crops like wheat, corn, soy, etc. I’ve been following most of the SCD for about 20 years without even knowing about it. I don’t eat processed foods; avoid anything made with white flour, white sugar, white rice, white potatoes, any corn or soy. I make my own foods like yogurt and fermented foods, grow and preserve as many fruits and vegetables as I can and avoid any foods known to be GMO. I don’t eat any meat/poultry/fish that’s been fed commercial feed since most of that has GMO ingredients. The few items I eat that are not on the diet are locally grown or produced (like maple syrup) so I know what’s in it. I’m in generally good health, not overweight, and friends are always asking what my secret is. It come down to… folks need to start growing and preparing their own food or visit your local farmer’s market, CSA, etc. Pay the farmer or pay the pharmacist, your choice.
