A spot check of eight different fast food places and found their burgers contained as little as two percent actual meat. The rest was made up of mostly water, with an unexpected side of blood vessels, nerves, fat, plant material, cartilage, and bone.
The sodium nitrite in burgers is used as a colouring agent. Research by the Cancer Research Centre of Hawaii and the University of Southern California found that the risk of pancreatic cancer was 67 percent higher for those consuming the most processed meats.
Ammonia is used to kill off pathogens found in the meat. According to a study on rats in Cancer Research, there is a connection between this chemical and colon cancer.
Preservatives have their perks, but what else is sodium benzoate doing besides keeping your meat fresh? According to a study in The Lancet, this chemical can also be affecting your children's energy. Adding sodium nitrite to their diet can result in increased hyperactivity.
If you suffer from asthma, it's in your best interest to avoid sulfites. These preservatives are used to maintain colour and increase shelf life, but a study in Clinical and Experimental Allergy showed that they can trigger an attack in 3 to 10 percent of asthmatics.
Carbon monoxide poisoning prevention has been drilled into us, which is why we all know not to leave our cars running in enclosed spaces. Carbon monoxide is used to bind with meat pigment and keep it looking red and fresh,
If you thought the fat in your burger would only affect your waistline, think again. Turns out, it could also be upping your cancer risk. When a burger is grilled, it becomes a polycyclic aromatic hydrocarbon. One of these PCA's, is benzopyrene, which can be found in more than just grilled meat. It's also labelled as one of the prime carcinogens in cigarette smoke.
The presence of glycotoxins in burgers, according to researchers at Mount Sinai Medical, are chemicals associated with diabetes, heart disease, and inflammation in general. Heterocyclic amines only make an appearance when you're flipping burgers at temperatures over 300 degrees. Too bad that only happens every time you fire up the grill because a Carcinogenesis study showed that rodents ingesting these chemicals developed breast and colon tumors, as well as leukemia.
All that is before we get to what goes in the bun.
