1) does not enough good bacteria automatically mean an abundance of not so good bacteria?
2) what kills good bacteria in the intestines aside from the usual Antibiotics ? pesticide from non organic foods? what else kills it? additives from food and sauces?
3) does kefir actually help repopulate the population of good bacteria or is it something that just adds to it? i mean like will you eventually be able to have enough of your own if you use kefir continuously or does the bacteria in kefir come out in your crap and you'll constantly have to drink more to replenish it?
