Fact Checked

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.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

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
swelling of the face or tongue

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.
