What is yeast?

Yeast is a living fungus which is used as an active ingredient in many foods and drinks, especially baked goods (baker’s yeast) and alcoholic drinks (brewer’s yeast). There are also many other forms of yeast, these include Candida (thrush) and others that live naturally in the body.

Can you outgrow a yeast intolerance?

Yes, it is possible to lose your intolerance to yeast, though you don’t necessarily ‘outgrow’ it. Following a 12-week elimination diet, you may be able to gradually introduce yeast back into your diet. As everybody is different, you should monitor any symptoms after consuming any foods or drinks which contain yeast. You may find you can only tolerate small amounts, or your body no longer reacts to this trigger food.

Throughout the elimination diet, it’s important you are balancing your diet with nutritious alternatives, especially those containing Vitamin B12 which is commonly found in foods made with yeast.

How long does it take for a yeast intolerance to show?

A food intolerance occurs when your body mistakes a harmless food protein as a threat and produces IgG antibodies – which may result in inflammation and discomfort. It is thought that symptoms of a food intolerance are likely to occur in a delayed fashion, typically between 2 to 72 hours.

Stress, medication, an unhealthy diet or the contraction of an infection can initially spark a yeast intolerance and, over a number of years, this can develop and progress in the body. For more information, you can read here.

What is the difference between an elimination diet for a yeast intolerance and the Candida diet?

The ‘Candida Diet’ focuses on trying to reduce natural yeasts from the body. Candida albicans is a normal part of your gut flora and can also be found in the mouth. However, a large consumption of sugar, alcohol and processed foods or an impaired immune system can destabilise your flora and Candida growth can spread.

This Candida overgrowth can show external symptoms, such as a reoccurring yeast infection, a white coating on the tongue and, in time, could lead to “leaky gut syndrome”. A “Candida cleanse”, which focuses on eliminating a wide range of ingredients from your diet can often be challenging and restrictive, including sugars, non-glutinous grains, dairy and fermented, processed foods.

The eating plan for a yeast intolerance, although similar, is less rigid and does not avoid as many foods. Addressing a yeast intolerance mainly focussing on removing yeast-containing foods and drinks from the diet that can be triggering inflammation in the body.

Which foods contain yeast?

Yeast intolerance is relatively common, yet finding which foods contain yeast can often be tricky as they can be found in many food and drinks that you would not expect.

As yeast covers a range of different type of foods and drinks, it may not necessarily be the yeast you are reacting to but other triggers instead, such as wheat, gluten or certain fruits. After finding out if you have a yeast intolerance, it’s wise to steer clear of any products which are fermented, processed and aged.

Here are some examples of ingredients which should be avoided on an elimination diet if you have a yeast intolerance:

  • Processed and cured meats
  • Aged cheese
  • Dried fruits
  • Gravy and stock cubes
  • Processed fruit juices
  • Condiments
  • Vinegar containing ingredients
  • Alcohol (brewer’s yeast)
  • Baked goods
  • Yeast extract

It is also a good idea to reduce your intake of sugary foods which can fuel the growth of natural yeasts in the body such as Candida (thrush).

Does yeast have other names?

Sometimes it isn’t as easy as picking something up from the supermarket shelf and looking for the term ‘yeast’. As an ingredient, yeast is often given other names which can make it difficult to identify on product packaging. Because of this, it’s a good idea to familiarise yourself with the other ingredients listed below. These names should be avoided if you have a yeast intolerance:

  • Hydrolysed protein
  • Hydrolysed vegetable protein
  • Leavening
What are yeast-free foods?

There are many alternative food and drink ingredients you can choose from which are yeast-free, so you can optimise and balance your diet effectively during your elimination diet.

You can supplement your meals with a variety of alternatives, such as the example grains below:

  • Quinoa
  • Millet
  • Brown rice
  • Buckwheat

If you have found out that you are intolerant to yeast, changing your diet need not be daunting. Nutritional consultations are provided with any of YorkTest’s full food intolerance programmes. These consultations are a worthwhile opportunity to discuss a range of alternatives not listed above which could support with your elimination diet. They will also give you personalised and specific advice on what foods and drinks you need to avoid which contain yeast that are currently in your diet.

Can I drink alcohol on a yeast-free diet?

Are you looking for yeast-free alcohol?  All alcoholic drinks rely on yeasts to produce the alcohol, hence the term ‘brewer’s yeast’. However, the process of distilling and filtering in some types of drinks will remove most of the yeast. Good news! You can still enjoy a small glass of champagne, and some spirits, though be wary of your mixers, especially if they have a high sugar content.

How do you test for a yeast intolerance?

There’s an easy way to determine if you are yeast intolerant. YorkTest has been providing IgG food intolerance testing for over 20 years. With a simple finger prick blood test, your results will show whether you have an intolerance to yeast.

YorkTest’s full food intolerance programmes include up to two 30-minute calls with a nutritional therapist. As yeast is often a hidden ingredient in many products, it’s a good idea to take note of their advice regarding suitable alternatives. They will also take into consideration other food triggers you may have.
