TBHQ is a synthetic antioxidant used as a preservative to extend the shelf life of processed foods by preventing fats and oils from spoiling. It is commonly found in packaged snacks, frozen foods, fast food, and oils.
How It May Affect You:
-
Potential Cancer Risk: While TBHQ is approved for use in small amounts, some studies on animals suggest that high doses of TBHQ may be linked to an increased risk of cancer, though more research is needed to determine its effects on humans.
-
Immune System Issues: TBHQ has been shown to affect the immune system in some studies, potentially leading to a weakened response to infections or allergies.
-
Behavioral Changes: Some research suggests that TBHQ could impact brain function and contribute to behavioral issues, particularly in children, similar to how artificial preservatives and additives have been linked to hyperactivity.
-
Digestive and Skin Reactions: In some individuals, TBHQ may cause digestive issues like nausea or stomach upset, and in rare cases, it may trigger skin rashes or other allergic reactions.
How to Avoid It:
To limit exposure, check ingredient labels for "TBHQ" or "E319," particularly in processed snacks, fried foods, and packaged goods. Opt for products that use natural preservatives like vitamin E (tocopherols) or rosemary extract, or choose fresh, whole foods that don’t require chemical preservatives. Look for foods labeled “preservative-free” or choose minimally processed options for a cleaner diet.
