Did you know that July 4th in the United States is national hot dog day?
This sausage sandwich is mainly made of grilled or steamed sausage served in sliced bread.
What are the hot dogs made of?
Hot dogs are made from leftover pork, chicken or beef. Offal, head, skin and even feet and adipose tissue are also used.
After cutting everything, it is all ground in the same way as the hamburger meat, pushing the pieces of meat through metal plates to have the same texture as minced meat.
Several ingredients are then added to the mixture including nitrates and nitrites which are two chemicals.
When these two components are heated, they are combined with the amines to form nitrosamines.
These are a family of extremely dangerous chemical compounds. They cause cancer, especially cancers of the stomach, colon, bladder and pancreas.
Science warns against the consumption of hot dogs:
In 2009, the American Institute for Cancer Research published a report based on the results of 7,000 scientific studies.
The researchers confirmed that every 50 grams of processed meat, a hot dog (some slices of mortadella or smoked bacon), is associated with a 42% increased risk of developing cardiovascular disease and 19% more risks of getting diabetes.
