1. Hot food
For a long time, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) has classified hot food and drinks exceeding 65 degrees Celsius into the list of group 2A carcinogens. This may confuse many people because hot food is often thought to be more delicious.

In fact, the surface of our esophageal mucosa is very fragile and can only withstand temperatures of about 60 degrees Celsius. When the esophageal and stomach mucosa is repeatedly damaged, it will cause inflammation, eventually leading to esophageal cancer and stomach cancer.

2. Salty food
Salted fish, a favorite dish of people in coastal areas of China, has been classified by the World Health Organization as a type 1 carcinogen. The main reason is related to the process of producing salted fish.

When making salted fish, it is necessary to marinate it with a high concentration of salt. Many nitrites are produced during the production process, and when nitrites enter the stomach, they will be converted into ammonium nitrites, which are highly carcinogenic. In fact, not only salted fish but also other salted dishes such as cabbage, dried vegetables, radishes, etc. can produce nitrites.

In addition, salted dishes contain a lot of sodium, which can cause high blood pressure. Therefore, according to dietary guidelines, the daily salt intake (including soy sauce, MSG, oyster sauce and other spices) of healthy adults should be less than 5g.

3. Greasy foods
Fast food is one of the foods that modern people love. But when oil is heated at high temperatures, it can produce acrylamide, a substance that can cause cancer and can harm the nervous system, cause early puberty and affect male reproductive health. For the sake of health, it is best to eat bland foods and eat more steamed foods.

4. Moldy food
Mold is a microorganism that grows in large numbers in warm, humid environments. Some molds can produce aflatoxin, which can contaminate grains, nuts, and milk. It is also a carcinogenic toxin and the most toxic of all mycotoxins that have been discovered.

Some consumers believe that moldy food can be eaten after removing the moldy parts. In fact, after moldy food, deep inside the food has formed fungal filaments that are difficult to see with the naked eye. If eaten, there is still a risk of disease.

Therefore, moldy food should be thrown away completely, do not let "disease enter the mouth" just to "save money".

5. Sugary foods
In 2020, researchers from the University of Paris in France found that the higher the total sugar consumption, the higher the risk of cancer, especially breast cancer.

Eating too much sugar for a long time, the body will convert sugar into fat leading to weight gain; sweets can also stimulate blood sugar levels to increase and continuously secrete insulin, easily leading to diabetes; increase the risk of heart disease. To prevent disease, the World Health Organization (WHO) recommends that each adult should only consume 25g of sugar per day.

6. Snacks
Packaged snacks or shrimp chips are an extremely delicious, cheap and easy to buy snack. However, according to researchers, this type of food contains a lot of calories that cause weight gain and dangerous preservatives. They also contain a huge amount of salt that puts pressure on many internal organs of the body, thereby increasing the risk of cancer cells forming.
