The article cited is typical Mercola - half truths, innuendo, scaremongering, and a big touch of inaccuracy.
The way it is written (for the gullible), Europe is way ahead of the US in dealing with artificial food colorants.
The truth is the other way round.
The FDA permits exactly seven (7) artificial colorants in foodstuffs.
In the EU, only six of those seven even have to carry a warning.
Just read the disclaimer at the bottom of the article:
*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease. If you are pregnant, nursing, taking medication, or have a medical condition, consult your physician before using this product.
Read it carefully, and conclude that you cannot rely on anything in the article - because it is the only product on that page.
The same disclaimer is on every page of the Mercola website - so by extension you cannot rely on anything on any page.
