I feel like diet doesn't matter so much with parasites cause it seems like there's no winning when it comes to diet. In a way id rather them be content in my stomach then go elsewhere so a little Sugar might not be a big deal.
Some diet things I think make a difference though like not eating too much fat/protein where the body has a hard time digesting it - whent his happens eating something like applesauce seems to help the food digest or go theough. Ultimately though I don't feel like a diet is a cure for these long going diseases by any means, but healthy foods/drinks like cucumbers and lemon water still seem to help somtimes though but apparently don't kill off these infections.
