Torula Yeast Allergy

Torula yeast is sometimes produced as a byproduct of paper production since it can grow on wood. It's used to enhance the flavor of processed foods, including crackers, salad dressing, snack foods, seasoning blends, processed meats, soups, rice and pasta dishes and sauces. It can cause adverse effects in people who are sensitive or allergic to it, but it's generally regarded as safe. Not all adverse effects are due to allergic reactions, but if you think you're having an allergic response, seek emergency medical attention 3.

Potential Adverse Effects

People who experience adverse reactions to MSG due to an intolerance may have similar reactions if they consume torula yeast. These can include:

• headache
  
• sweating
  
• flushing
  
• nausea
  
• chest pain
  
• rapid heartbeat
  
• shortness of breath

Symptoms of a true allergic reaction include

• hives
  
• rashes
  
• red eyes
  
• nasal congestion
  
• cough
  
• difficulty breathing or swallowing
  
• dizziness

People can also develop a condition called allergic fungal sinusitis due to torula, according to an article published in Asia Pacific Allergy in October 2011. Symptoms of this condition include runny nose, sneezing and blockage of the nose.
