Junk food giant Burger King has pulled out of talks with the UK's Food Standards Agency (FSA), which were designed to find ways to make fast food less deadly. Meanwhile, the chain continues to introduce new menu items that are more unhealthy than even previous meals. For example, Burger King recently introduced a new product called the "Enormous Omelet Sandwich," which has eggs, American cheese, bacon, sausage and ham and which totals 740 calories, nearly five grams of salt, 46 grams of fat -- 16 grams of which are saturated fat -- and 330 milligrams of cholesterol.
