Have you seen the forum’s protocol where it mentions how to reintroduce foods and when? A lot of the foods you are wanting to add in are stage 2 foods for when you are symptom free, so I wouldn’t introduce all of those anytime soon. I would try out coconut milk at first but its not going to be similar to regular milk. It is also highly inflammatory which isn’t good if you have leaky gut or allergies.
What is your diet like so far?
Flu like symptoms are die-off symptoms.
