Eating right, moving your body, staying hydrated all help with elimination.
I used to read Dr. Gundry’s posts but I always questioned foods he said not to eat. I quit reading anything from him when he said we should not eat avocados and he started pushing what he sells. Avocados are very healthy - good fats, fiber, lots of nutrients. Google it and see the list. Avocado oil is also good to cook with.
