Some U.S. residents may not know that the States have notoriously relaxed regulations regarding food ingredients, especially compared to other parts of the world. American standbys such as Lucky Charms, Swiss Rolls, Mountain Dew, and even Pop-Tarts are either banned or sold with a warning label in other countries.
Pop-Tarts are not allowed in some European countries due to their use of food dyes such as Yellow 5 and Red 40. These dyes are banned in Finland, France, Austria, Norway, and the U.K., due to scientific studies that proved adverse effects on children who regularly consume them; concerns range from cancer to hyperactivity and other behavioral issues.
In 2010, the European Parliament mandated that foods containing six specific artificial dyes must carry a warning label, and for foods created specifically for kids, the use of these dyes is banned. While people in the U.S. are consuming more food dyes than ever, other countries are sourcing natural colors from produce like carrots, pumpkin, and berries.
