This paragraph from an article in the New York Times speak for itself:

Mr. Kennedy has singled out Froot Loops as an example of a product with too many artificial ingredients, questioning why the Canadian version has fewer than the U.S. version. But he was wrong. The ingredient list is roughly the same, although Canada’s has natural colorings made from blueberries and carrots while the U.S. product contains red dye 40, yellow 5 and blue 1 as well as Butylated hydroxytoluene, or BHT, a lab-made chemical that is used “for freshness,” according to the ingredient label.
