Just FYI, the dairy components of the diet are often omitted. I started out on SCD, but without the dairy, and then realized it was virtually the same as a "paleo diet" but with a lot more fussing over food. So I switched to paleo. I've since found there's things other than dairy and gluten that cause me issues. It seems like foods like nuts and seeds do as well. I can eat small amounts of them, but if I over do it I have some pretty severe intestinal issues.
Regarding the Specific Carbohydrate Diet I have researched it a number of times but do not have Elaine's book. I usually give up after looking at the allowed foods. The homemade yogurt seems to be very important to the diet (I cannot tolerate dairy in any form). Plus yogurt prepared over 24 hours will be very acidic (another major no, no, for me). I can't eat eggs, beef or pork or nuts. Quinoa, rice and corn have all been tried and have gone by the wayside. It looks like there would be very little left for me to eat on the SCD. I presently eat regular potatoes and sweet potatoes on a regular basis (they are not allowed on the SCD). The rest of my almost tolerable foods include salmon, chicken breast, avacado, grapes, canned pears, green beans, carrots & canned mandarin oranges, clarified butter. That's about it! I have tried over the last two years slowly introducing new foods but they have been a failure in most cases. The sweet potatoes were just started about a month ago and seem to be tolerable. I take a Folate/VitB12 supplement. Other than that I am stumped. Am I misunderstanding something about the SCD diet??
It is a bit of trial and error and it takes a good positive mental outlook to make a lot of dietary changes, but lots of people do it successfully.
I hope you figure out what helps you!
