Here is a list of foods that should be avoided if you have yeast issues.
Bread with yeast in it:
This includes pastries, doughnuts, pretzels, and crackers. Harsh, I know!
Potatoes and potato products
Corn and corn products
Read your labels, almost everything processed or refined has potato or corn starch in it, It's terrible!
Fruit sugars will feed yeast too, so if you are trying to kill yeast off, avoid fruits during initial cleansing.
Peanuts (these are actually considered a legume, and they are in more of the fungus family)
Aged foods such as cheese
left overs over 2 days old
Red meat (very harsh on digestive lining, and it takes 3-5 days to fully digest it, and it can add to any bacterial issues).
