E319 Tert-Butylhydroquinone

What is E319 or Tert-Butylhydroquinone?

tert-Butylhydroquinone (TBHQ), or E319, is a synthetic antioxidant used to prolong the shelf life of processed foods by preventing fats and oils from oxidizing. It is found in snacks, fast food, and processed baked goods, helping to maintain their freshness.

Why do I have an intolerance?

Some individuals develop an intolerance to TBHQ due to the body’s inability to process synthetic antioxidants effectively. Over time, consuming TBHQ in large quantities can lead to adverse reactions such as stomach upset, dizziness, or allergic responses. The body may treat TBHQ as a harmful substance, resulting in these symptoms.

What can I do about it?

To avoid TBHQ, check labels of processed and packaged foods, particularly snacks and fast foods, as they often contain E319. Opt for fresh, unprocessed alternatives or make your own snacks at home to eliminate exposure to this preservative. Limiting processed foods overall can help reduce the risk of intolerance.
