This may not be the best thread for this, if not, I apologize. However we chatted at length a couple of nights ago with two women who are vegans (no meat, chicken, fish, eggs, cheese, etc). They talked about how they believed their gut biomes changed within about 21 days of having changed to vegan diets. Their stories were quite compelling. Even though we eat all organic fruits and vegetables and organic fed meats (when we do eat it) the ’21 day vegan challenge’ to see if there is a difference is strong. Has anyone gone Vegan and noticed immediate changes in their health?
