I don’t know what strict food list you are referring to but here is mine:
The beef can set you back because it takes 1-2 days to digest whereas chicken/fish take hours to digest. The beef and pork can cause constipation.
I don’t know where you read that you shouldn’t have carbs, but you need them to be healthy…the yeast feeds on everything strict diet or not.
Oat bran does contain gluten so this is why you should be very careful with it as a food item. On my food list there is an asterisk next to it, which means it can cause problems. You need to learn about testing foods properly and what side effects to look for.
As far as milk and cheerios, that shouldn’t be on the diet as you may know…
For a great replacement for oat bran, I recommend cream of buckwheat which has a similar texture.
