ve learned to do, when I go through periods of antiobiotics, is not eat too much fruit (eat more vegetables and take
vitamins, whole food
vitamins that I think work a little better than the regular type of vitamins), not eat too much sugary stuff, no refined sugar, etc. I'm also diabetic, so I've been watching my sugar levels now, which I think has helped. You could google killing yeast and see what comes up.
Oh, so bad food to eat is sugar and white flour.
