Yeast allergies and intolerances are caused from eating foods containing yeast and symptoms may be similar, however, this should not be confused with yeast infections.
As I understand it there are 3 types of yeast in foods. Baker’s yeast is used in bakery to help it rise. Brewer’s yeast is used for fermentation in alcohol which in turn helps create the bubbles in some beer and wine. Wild Yeast is found naturally on some fruits (especially grape skins and plumbs), some grains and in sourdough for example.
You may be intolerant to baker’s yeast, brewer’s yeast, wild yeast or all three of them. If you’re not sure it’s best to try food separately on separate days to eliminate the offender. If you’re intolerant to only one type of yeast – awesome – your menu selection just got bigger.
To the best of my knowledge it is best to avoid foods that are high in carbohydrates and sugar because yeast thrive on them (eg some fruits). Again, try to avoid packaged and processed food. Here are a few suggestions.
