Recently, Buzzfeed posted an article claiming that ingredients used in particular foods are linked to severe health defects. Now I know Buzzfeed doesn't exactly promise quality information, but I have seen this article passed around on social media sites quite a bit. The article is filled with bunk and misunderstandings of chemistry and toxicology. A chemist named Derek Lowe wrote a blog voicing his frustration at misunderstood science being spread so easily and explains how the claims concerning each of the 8 foods listed in the article are a result of what he calls "chemophobia." http://pipeline.corante.com/archives/2013/06/21/eight_toxic_foods_a_little_chemical_education.php Misunderstandings of these topics bleed into similar issues that have been discussed heavily in other threads on this site like GMOs and water fluoridation, the blog post is a great read. As for the Buzzfeed article's claims on the foods being banned in other countries, the legitimacy and reasons for the bans varies with which food and country we are talking about. For example, SOME food colorings are banned everywhere while others have been tested and approved, also Norway's ban on food dyes was lifted in 2001. Regardless of where it may banned for whatever reason, the science concerning each chemical is sound.
