Hot dogs are probably the most popular fast-food ever, as they have over 7 billion consumers in the world. However, according to recent research, this fast-food is also the leading cause for four types of cancer.
Hot dogs were introduced by German immigrants in the 19th century and gained their popularity quickly. These days, the hot dog enjoys an iconic status. The WHO (World Health Organization) recently issues a report that suggests all processed meals can cause cancer, including red meat. The hot dogs are made of pork, beef and chicken. Factories often use leftovers from cutting steaks and pork chops as well as edible slaughter by-products such as animal feet or head, fatty tissue and skins.
