The gelatin and minerals in bone broth is supposedly very healing, though it would seem unlikely to work overnight...maybe it is just what you needed. Organ meats and Bone broth are encouraged on each diet I mentioned. If you are eating LC, eliminating all grains and sugar is SOP. Dairy has good substitutes like coconut milk. Use olive and coconut oils rather than vegetable oils. The websites have good recipes and ideas for what to eat and substitute. Good luck narrowing it down. If it is dairy, Kresser has you add only ONE product back, eat for three days, wait for three days. Then add ONE more product, and on. So Butter, then HWC, then yogurt...right there is 18 more days beyond the 30.
