Restoring the gut ecosystem/function involves much more than just the liver. For some of us it is much more complex. There are a lot of people with candida that can not do potatoes/ starchy foods because of the way they can ferment in the colon(including myself). I as well cant do too much hard to digest fats, but i still need some good fats in my diet. Each person has to figure out what diet works best for them because each individuals situation can be very different according to their flora/digestive makeup.
