I've been on SCD for 6 months and I've never even tried almond flour yet. I don't even eat the yogurt because I don't tolerate dairy products of any kind (except for eggs). In fact, I didn't follow the introductory diet at all. When I was just starting with a bad flare, all I ate was meat, eggs, bananas, and cooked vegetables. Currently, I eat only meat, fish, vegetables and fruit. Don't let the introductory diet discourage you. Just follow the basic premise of the diet - no starches or lactose of any kind! Activia is illegal on the diet. You don't have to spend a lot of money on the diet and you don't have to eat everything on the legal list, like dry curd cheese, which I was never able to find.
