Yeast Intolerance: symptoms and food to avoid

What is yeast? 

Yeast is found in many different foods and drinks such as bread, cereal and beer. If you have an intolerance, the body struggles to digest and break down foods containing yeast, leading to unpleasant, often painful, symptoms. There are also other forms of yeast, including Candida which lives naturally in the body. 

Is yeast intolerance the same as a yeast allergy? 

Yeast intolerance is not the same as a yeast allergy. Allergies are a serious, potentially life-threatening, condition that occurs when the body identifies food to be a foreign substance. This can lead to symptoms that range from mild (rashes and itching) to severe (anaphylactic shock and death). 

What are the symptoms of yeast intolerance? 

Yeast intolerance has a broad range of symptoms, including: 

  • Flatulence 
  • Stomach cramps 
  • Bad breath 
  • Fatigue 
  • Bloating 
  • Diarrhoea  
  • Indigestion 

If symptoms persist or are particularly acute, please seek advice from your GP or a medical professional. 

What foods to avoid if you have a yeast intolerance  

Yeast is found in lots of different food and drinks. These include: 

  • Baked goods – e.g. bread, crackers, croissants, pasties and biscuits. 
  • Processed and fried foods – such as pizzas, burgers and chips 
  • Alcohol - particularly beer, wine and ciders 
  • Cereals and cereal bars 
  • Sweets 
  • Cured meats 
  • Dried fruits, berries and grapes 

Can you bake bread without yeast? 

The good news is it is entirely possible to bake your own yeast-free bread that taste just as good as its yeast counterparts.  You’ll find lots of great recipes online but here’s one of our favourites, which contain flour, bicarbonate of soda, salt, sugar, oats and yogurt or buttermilk….and no yeast!

I drank too much alcohol and had unhealthy eating habits. Pastry is such a bad thing, it's all those pies, pasties and sausage rolls!

How does this work?

The tailored approach LiveWell Dorset uses to come up with solutions to the things that are stopping us achieving our goals, is based upon work done by University College London developing the COM-B model of behaviour change. In this model, all behaviour is influenced by understanding a person’s capability to change, their opportunity to change and their motivation to change. By understanding which of these is the biggest barrier to change, we can tailor support accordingly. This model of behaviour change is at the centre of the support we offer, online and in person.
