Cancer, though a simple word, is frightening. When it comes to carcinogens, everyone will be able to avoid eating or touching them. This year, salted fish and overnight vegetables were added to the list of carcinogens. Salted fish is salted fish, then dried. Because there was no low-temperature storage technology before, fish was easy to rot, so people thought of this method. Nitrite can inhibit the growth of spoilage bacteria such as Clostridium botulinum during the curing of salted fish, and has good coloring and antioxidant effects, and can improve the flavor of cured food.
Nitrite reacts with amine, the decomposition product of protein in pickled products, to produce carcinogen nitrous acid. Many people will think that our hometown or elders have eaten salted fish all their lives and no one has cancer! In fact, the so-called carcinogens are substances that have obvious carcinogenic effects on the human body, but they are not necessarily carcinogenic. Moreover, salted fish is like pickled vegetables, which are relatively safe if pickled for enough time.
What foods in life have carcinogenic effects?
1. Pickled food
Some pickled foods are easy to cause cancer. For example, dimethyl nitrite produced in salted fish will be converted into carcinogenic dimethyl ammonium nitrite in human body. Some pickles, salted duck eggs and salted eggs all contain these carcinogens, so you should eat as little as possible.
2. Smoked food
Smoked food, such as bacon, smoked liver, smoked fish, etc. Containing benzopyrene carcinogens, eating these foods often can lead to esophageal cancer and gastric cancer.
3. Moldy substances
After some things are damp and moldy, they will produce carcinogenic toxin-aflatoxin after being contaminated by mold. Such as moldy corn, beans, rice, wheat and so on.
4. Overnight leftovers
Even if overnight meals are put in the refrigerator, bacteria will breed. It will also be converted into nitrite, causing cancer. As the above foods may cause cancer, we'd better eat less. Eating more healthy and fresh vegetables and fruits can also ensure good health!
