What foods or drinks are to prevent or cure cyst infections?

it probably won't cure it but there have been studies showing that yogurt helps. There is a probiotitc in some yogurts, Lactobacillus rhamnosus, that's a transitory colonizer of the intestines; studies have shown it to aid in lessening the affects of allergic reactions, and keeping pathogenic bacteria at bay. It may help. but its definitely not a cure.
