About three years ago I got scared when sometimes I would go three days without a bowel movement. Changes of diet were gravitating to whole food values and benefits were importantly noticed with info stating high vitamin c menus assist immensely in this. At that time I just happened to be moving towards home-made sauerkrauts in variation or fresh juice and/or fruit like cranberries (if not sparkly popping yet)soaks conducting them which are reported for that content and there was intense soothing... {coconut water liquid if still too subtle to sip all, poured on something, covered for day or two is a simple rebalancer, my first of many / i.e. succulent tomatoes}
Of course there's lacto bacillus involved in such meals, so generate as much natural means for maximum nutrition instead extracting guesses. [and not to forget exercise yes, but what forges you ahead too!]
