I came across this compound some time ago trying to avoid at first due to concerns as to its disputed carcinogenicity. At least one butter brand in my country lists it as a conservative along BHA; other brands don't mention anything about these two antioxidants. Now I wonder how much BHT is there in, say, 100g of butter. Would the beneficial effects of BHT be noticeable at doses usually met by moderate butter consumption?
