The salted fish is a kind of popular food in the south of China. It is delicious and adds a salty flavor to other dishes. But eating too much salted fish can give you cancer. We can see it clearly on the list of cancercausing foods, which was recently published by the China Food and Drug Administration(中国食品药品监督管理局)．
The salted fish is produced with a large amount of salt, which later turns into nitrites(亚硝酸盐). When nitrites reach our stomach, they turn into another kind of chemical that can cause cancer.
So does this mean we can't eat salted fish anymore?
“People don't need to worry too much. Cancer is concerned with how often you eat certain foods and how much of them you eat，” Huang said. If you really like eating salted fish, you can eat a small amount once or twice a month. Meanwhile, you should also eat more fruit and vegetables that are rich in vitamin C, as this can help to prevent the formation of nitrites.
In fact, there are many foods that we often eat that are thought to cause cancer, such as pickles(咸菜), areca palms(槟榔) and so on.
Although these foods may bring cancer, it doesn't mean a person will get cancer just from eating them. Cancer is caused by many different factors, such as one's genes, environment, lifestyle and eating habits. As long as one has a balanced diet, he doesn't need to avoid cancercausing foods entirely.
