The role of BHT in shredded wheat products
Shredded wheat is often marketed as a simple, one-ingredient cereal made from 100% whole grain wheat. While the cereal itself may contain only whole grain wheat, some brands add the synthetic antioxidant BHT (butylated hydroxytoluene) to the inner plastic packaging to prevent the cereal's natural fats and oils from oxidizing and going rancid.
This practice is not universal across all brands or countries. For example, some Post Shredded Wheat products in North America explicitly list "BHT is added to package material to help maintain product freshness". In contrast, versions produced for the UK market by Nestlé advertise their Shredded Wheat as having no added sugar or salt and being made of only whole grain wheat, implying the absence of such additives. This variation highlights the importance of reading packaging labels carefully and noting regional differences.
How BHT works as a preservative
BHT functions as a free radical scavenger, which means it neutralizes unstable molecules that can cause fats and oils to degrade. Without this antioxidant protection, the cereal could develop an off-taste and unpleasant smell, reducing its overall quality and shelf life. By adding BHT to the packaging material, manufacturers can ensure that the cereal remains fresh and palatable for longer periods, which is essential for shelf-stable products.
The BHT controversy and consumer choice
For years, BHT has been a subject of debate among health advocates and regulatory bodies. While the U.S. Food and Drug Administration (FDA) has classified BHT as 'generally recognized as safe' (GRAS) for use in food at regulated levels, it remains a point of concern for some consumers. In fact, growing consumer awareness led General Mills to start removing BHT from its cereals in 2015.
Potential health concerns associated with BHT
- Endocrine disruption: Concerns have been raised that BHT may act as an endocrine disruptor, interfering with hormone function, based on some animal studies.
- Carcinogenic potential (animal studies): The International Agency for Research on Cancer (IARC) has classified the related additive BHA as a possible human carcinogen, and some studies using high doses of BHT in animals have shown toxic effects on the liver and lungs.
- Conflicting evidence: It is important to note that many studies showing adverse effects used extremely high doses in animal models, far exceeding typical human consumption levels. Other research has shown mixed results, and regulatory bodies have deemed it safe at current consumption levels.
Checking for BHT and exploring alternatives
For the health-conscious consumer, navigating the cereal aisle can be a challenge. However, being an informed shopper is the first step toward making choices that align with your dietary preferences.
Tips for identifying BHT:
- Read the ingredient label: BHT must be listed if it's in the product. Look for "BHT added to preserve freshness" or "BHT added to packaging material".
- Check the brand and region: Be aware that the same brand name may have different ingredient formulations depending on the country. Look for brands that explicitly state 'no preservatives' or 'only one ingredient'.
- Choose organic or natural options: Many organic or natural cereal brands avoid synthetic additives like BHT and instead use natural alternatives like Vitamin E (tocopherols) or rosemary extract.

Conclusion
The question, "Is there BHT in shredded wheat?", does not have a single answer, as the presence of this preservative varies by brand and region. While BHT is approved by regulatory agencies, concerns persist among some consumers, leading to a demand for preservative-free options. By reading ingredient labels and understanding the differences between brands, consumers can make an informed choice that aligns with their nutritional goals. Ultimately, many delicious and healthy breakfast alternatives exist that allow for a diet free of synthetic antioxidants like BHT.
