1. It is convenient and cheap, and can be used as a dinner.

2. Hot dogs and sausages are delicious and satisfy your appetite.

Disadvantages:

1. Sausages are easy to get moldy if they are kept for a long time.

Clinically, moldy sausages are contaminated by a virulent botulinum. People will cause food poisoning after eating contaminated sausages.

Many people eat hot dog and ham sandwiches every day, but they don't know that these processed foods are hidden dangers: not only a lot of ptomaine and pesticides, but also a variety of carcinogens. In order to save your life, it is better to stay at a respectful distance from others.

In recent years, more and more scientific evidence confirms that eating sausages and ham greatly increases the chance of cancer.

As early as 1950s, scientists have discovered that nitrosamines, a chemical, can cause liver cancer. In 1954, four chemists in a British university suffered from cirrhosis at the same time, and one of them died. As a result of the investigation, it was found that they had eaten dimethylnitrosamine in the experiment. Two years later, more animal experiments confirmed that dimethylnitrosamine can cause liver cancer.

A German chemist quietly put a small amount of nitrosamines in jam for his wife to eat every day. As a result, she died of poison and still didn't know that her husband had murdered her.

During the production of sausages, ham, barbecued pork, sausage, lunch meat, salted beef and other foods, nitric acid is added, which reacts chemically with heme in the meat, looks beautiful and pink, and also has the effect of sterilization and preservation.

After these nitric acids are eaten in people's intestines and stomach, they will be decomposed into nitrous acid, which will react chemically with the amines contained in meat and become nitrosamines.

Eating too many hot dogs is easy to get fat.
