Yeasts are organisms in the fungi kingdom. Of the 1,500 or so species of yeasts that have been discovered so far, two are of particular interest to people with allergies: Saccharomyces cerevisiae (used in baking and brewing) and Candida albicans (responsible for candidiasis i.e. yeast infections).

Other species of yeast are involved in both food production (useful) and infection. This article is confined to discussing Saccharomyces cerevisiae and Candida albicans.

Yeast and Food

yeast-colourful-300pxThe use of yeast to produce food and alcohol is an ancient practice. It is particularly useful for producing bread and beer.

Depending on your tolerance for yeast, you may be able to have a limited quantity of some types of food that use yeast.


In bread, the growth of yeast releases carbon dioxide, which forces the bread to rise. Yeast does not survive the baking process, but many of the allergy-causing proteins do. For this reason, you may find that bread causes problems if you are allergic to yeast. It may also be one reason that some people feel fatigue after eating bread.

Yeast Extract

Some foods made primarily of yeast. See Foods That Always Contain Yeast on this website.

Beer and Wine

Yeast produces alcohol during beer brewing and wine fermentation. It also causes the fizz in beer and some sparkling wines. The yeast in beer and wine can be alive when you drink it. For this reason, beer and wine are especially bad for people with a yeast allergy. It can also cause fatigue after drinking beer or wine.

Distilled Alcohol

Yeast is used in the fist stage of alcohol production. Spirits such as rum, whisky and brandy. The distilling process concentrates the alcohol and leaves most of the yeast behind. Vodka and gin are especially pure and generally safe for people who must avoid yeast. Some methods of distilling are less efficient. Some types of single malt whisky for example, may have higher levels of yeast than a typical blended product. This level may or may not be within your tolerance for yeast intake.

Yeast Infections

The most common type of yeast infection is caused primarily by Candida albicans. This is not an allergy, but if you are allergic to yeast, a yeast infection may cause you to suffer both from the direct symptoms of a yeast infection as well as your yeast allergy symptoms.

Recently been diagnosed being Allergic to yeast, dust and weeds. My scalp has been itching quite a while with no flaking or dryness. Read selenium is beneficial for itchie scalp. I read on the label that it contains brewers yeast. Is this the same as yeast that I am allergic to.

I was in n out of hospital for years and no doctor knew what was up with me. I had hidden gallstones,apendictis, ibs. I went on the keto diet and discovered it was yeast I was allergic to. There’s not much info on it as I tend to find its yeast extract I really react to. I still eat bread on the rare occasions but nor very often. I find any sauce with yeast extract reacts with me quickly. Also beer and wine. Thank god for vodka. Yeast allergys need to be researched more I spent years in pain and I when the hospital used to bring me soup I didn’t know it was making me worse. (Stock cubes have a huge yeast extract content) at one point I was diagnosed as anorexic. Coz I lost so much weight but I was so hungry but everything hurt that I ate. Anybody with any symptoms like this try a yeast free diet. I feel great now

I have very bad yeast problems. I invented a diet and work out plan and lost 17 pounds in a month. It is very hard but my recipes are really good. Im thinking about writing an ebook.

My daughers has recently found out she has an significant allergy to brewers yeast (and eggs, dairy and some other things) but not bakers yeast. It is difficult to find info on this. Can a person use Braggs Liquid Aminos and Braggs Apple Cider Vinegar, I am not understanding the fermenting thing totally. Looking forward to hearing from you.

see my comment on the website, but my daughter has an allergy to yeast, nuts, wheat, oat, virtually everything we find has one or the other in it. it took us a good year to figure it all out, and the whole time she was a trooper and broken out in Hives! Vegetable oil contains yeast, xantham gum is another word for yeast bascially, home made items are probably your best bet, and I KNOW FROM EXPERIENCE, I hardly have the time to cook pre-pared foods, let alone bake and cook from scratch!!! Visit a nutritionist, they can help with the “Hidden” ingredients, just a half dozen visits helped me out immensely; for a good treat – Chick a fil restaruants are all allergy free, they strip down the proteins? from their foods, and my daughter, who is highly sensitive, can eat anything there, I wish I had the money for stock, and to hire one of their chefs! or whomever figured the strip down process, because i would like to know.. good luck

Enriched flours contain vitamins that are often sourced from yeast. If you have wheat it should be free of all additives. Sugar alcohols like sorbitol are bad. There’s quite a few sugar alcohols. Citric acid is often produced by feeding bread mold corn sugar and that’s in most things. I’m highly sensitive to dairy, eggs, and yeast. I try to eat paleo aip meals for simplicity and a lot of whole foods. Tested in 2013. Still trying to make bread that doesn’t suck. Super chewy tapioca flatbread is okay, but I have TMJ. Other option so far is heavy donut like soda bread. When places have safe burgers, I get them to wrap it in iceberg lettuce if possible.

I had a blood test done and it shows that I am allergic to yeast as well as cow’s milk. Should I stay away from wheat as well?

Nothing in your test says you should stay away from wheat. However, if you cut out yeast and milk and still don’t feel better, try cutting out wheat. A wheat-free/gluten-free diet does seem to help a lot of people.

I am starting the elimination diet. Just wanna know from some veterans….when I start reintroducing food to my diet, am I looking for reactions from foods containing yeast vs ones that contain sugar/sweeteners? It has become apparent to me that there are two concerns with the foods. It may either contain yeast or it contains the food for the yeast. I would imagine that if there is a yeast imbalance that perhaps once an elimination diet is done, perhaps yeast items should be reintroduced first and then sugary items (or vice versa) to find a culprit? Anyone have any thoughts or stories to share on the yeast vs sugar theory?

I love reading that other people have similar problems as myself. My dilema is that I am sensitive to yeast, wheat, dairy, several veggies such as beans, brocolli, carrots, cauliflower as well as eggs. I am having an extremely hard time finding things to eat. Any suggestions.

yeast is a tough one, my daughter became allergic over 2 years ago, she is 9 now; we went through a good year of trial and error! visiting a nutritionist helped as Yeast is a hidden ingredient in alot of items. i was ordering food online for my daughter, but recently a local Walmart has started stocking alot of yeast free items; I should say that my daughter is allergic to wheat (contains yeast) oats, and nuts too, all at the same time. Vegetable oil is a big one that has yeast in it, anything cooked in vegetable oil (90% of the restaurants out there) cook in vegetable oil, which is horrible for a little girl – Chick a fil restaurants are ok though, they are the only place that I know of that all of their products are stripped down and are allergy free ! no joke! i wish i had their chefs on speed dial ! let me see, the ener g foods has a good sampling of products that we were able to get, pizza crusts, donuts, cookies, until Walmart started stocking some of these items for us, I tried to bake bread, but it hasnt come out ok yet, if anyone has ideas on baking bread with out yeast – rice bread that is, no wheat, as she is allergic; just remember with a yeast allergy, always second guess, when you ask some one of the ingredients in something, and they say why what is she allergic too? and you say yeast, they say oh, it doesnt have that, ask again for a list of the ingredients, alot of foods have yeast and it is hidden, trial and error, and luckily, the worst response we have had so far is hives and throwing up, no epi pen yet needed. just be careful, and GLUTEN FREE is not YEAST FREE ! I hate that for some reason alot of people think that, and i look at ingredients and see xantham gum or vegetable oil, and remember to do research, research research; and unfortunately, I spend alot of my Sundays cooking up dinners and snacks for the week — Fresh and home made is the best, you always know what the ingredients are !
