And that's only one ingredient that we now know that it causes a disease. Recently I saw a tv documentation about asbestos. It took more than 50 years to ban it - and this not even worldwide as in India it still is a common construction material and I saw a factory where workers handle it without gloves or head mask.
A good question also is: if we now know that it causes diseases (the butter flavouring) - why wait another three years? How many people does the industry want to make suffer for the sake of revenues. It's really always the same old story... . The only thing we can really do is eat somewhat naturally grown and produced ingredients. And that's hard... and expensive.
