Many of the chemicals found in America's most common foods are considered to be so unhealthy that they're actually illegal in other countries. Rich Food, Poor Food by [Dr.] Jayson Calton and Mira Calton, a certified nutritionist, features a list of what the authors call 'Banned Bad Boys' - a list of the ingredients, where they're banned and what caused governments to ban them. One of the most common 'Bad Boys' is different variations of food coloring, which actually is made from petroleum and is found in everyday items like soda, sports drinks, mac and cheese, cake, candy and several other common, American products. The chemicals used to make these different dyes have proven to cause various different cancers and can even potentially mutate healthy DNA. European countries like Norway, Finland, France and Austria all have banned at least one variation of petroleum-containing food coloring. Another common additive banned in other countries but allowed in the U.S. is Olestra, which essentially is a fat substitute found in products that traditionally have actual fat. For example, low-fat potato chips ... contain Olestra - which is shown to cause the depletion of fat-soluble vitamins. Olestra has been banned in several countries, including the United Kingdom and Canada. In 2003, the FDA lifted a requirement forcing companies that use Olestra in their products to include a label warning consumers that the food their eating could cause 'cramps and diarrhea,' despite the fact that the agency received more than 20,000 reports of gastrointestinal complaints among olestra eaters.
