In the past, people always thought that cancer was far away from them, but nowadays, cancer has become a more prevalent disease that may threaten health and life in serious cases.
In addition to environmental changes, the occurrence of cancer is also closely related to some common carcinogenic substances.
Therefore, we need to understand these carcinogens and stay away from them in time to help reduce the chance of cancer.
What are the common primary carcinogens around us?
Before understanding carcinogens, we need to understand the concept of Class I carcinogens, which have been identified through animal tests and population epidemiological surveys and have clear carcinogenic effects on humans. It may exist in food, environment.
1、 Aflatoxin
This is one of the most powerful carcinogenic substances that we can find so far, one milligram is enough to cause cancer.
And this substance may exist in a variety of food, such as moldy peanut corn, spoiled rice, bitter-tasting nuts, substandard quality of sesame paste, fried peanut oil with native methods, once found these foods should be promptly discarded.
In addition, there are chopsticks that have been used for a long time can also exist aflatoxin.
- Benzo(a)pyrene
This is also a strong carcinogenic substance that can increase the risk of many cancers, such as lung cancer, liver cancer, stomach cancer, intestinal cancer and so on. Benzopyrene can be found in many substances.
For example, high-temperature frying food, because vegetable oil will produce this substance after high temperature.
The smoke from frying also contains benzopyrene.
The charcoal used for smoking contains benzopyrene, so the grilled meat we usually love to eat may also cause cancer.
Ink also contains benzopyrene, so try not to use the ink wrapping paper wrapped food before drying.
- Ammonium nitrite
Ammonium nitrite is a kind of indirectly carcinogenic substance because it will combine with protein decomposition after entering the body to form a strong carcinogenic substance nitrosamine.
Many foods contain this substance, such as processed meat products, more common are ham, bacon and so on.
In addition, overnight dishes also contain this substance, it is recommended to make the right amount of meals every meal, pickled food also contains ammonium nitrite.
4、 Formaldehyde
Japan’s Yokohama National University has concluded that the release of formaldehyde is a continuous process, sometimes up to 10-15 years, increasing the chances of cancer.
Many products are rich in this substance, such as the hooking glue used in decoration, substandard water products, poor quality clothes, car foot mats, substandard imitation porcelain tableware.
How to prevent primary carcinogens?
1、 Do not eat leftover food
Aflatoxin and ammonium nitrite are easily produced in leftovers.
Therefore, try not to eat leftovers, especially moldy food, in addition to bitter nuts, also spit out and immediately rinse your mouth, eat raw peanuts when soaked in advance.
2, a bad whole throw away
Aflatoxin’s ability to spread is particularly strong, such as a bad peanut, a whole bowl of peanuts may be present in this substance.
Therefore, when one part of the overall food is moldy, the other parts of the food should not be consumed as much as possible, and all the food should be thrown away.
3, do not eat self-extracted oil
Some peanuts do not appear any abnormal appearance, but there is already aflatoxin inside, and the process of making self-extracted oil is relatively simple, even without the process of removing toxic substances.
So try not to eat self-pressed oil.
- Wooden chopsticks should be replaced regularly
Although chopsticks themselves do not produce aflatoxin, the humid environment and food residues may produce this substance.
Therefore, rinse chopsticks with running water and store them in a cool, dry place, and even then, replace them every 3-6 months.
