so according to the bad environmental situation which not seem to change in the next time, one has to stay on the antiparasite program the rest of the life?
you wont be able to avoid breathing, drinking and eating and there is no possibilitiy to only get healthy stuff (for example filtering water always pollutes the water again instantly....destill you water and you pollute it with metal, take reverse osmosis and you pollute your water with plastic)
so what kind of nutrition is the one which prevent new gallstones and parasites?
