Wide range of fat-containing products.

BHT can cause liver damage in high concentrations; (pseudo-) allergic symptoms have also been reported. In some people with a hereditary isomer of a specific liver enzyme it can cause migraine. Due to the side effects, the EU has restricted its use; thus, the number of BHT-containing products will decline in the next few years.
E321 can normally be consumed by all religious groups, vegans and vegetarians.
