In order for nasopharyngeal cancer patients to better cooperate with the treatment, the family members of the patients should know some necessary general knowledge about nasopharyngeal cancer. Improper diet can also lead to nasopharyngeal cancer. Then, what are the dietary taboos of nasopharyngeal cancer? Nasopharyngeal Cancer Dietary Note: As we all know, patients’ diet cannot be like normal people’s diet, especially nasopharyngeal cancer patients’ diet. Since nasopharyngeal cancer disease deteriorates to a high degree, if diet is not prudent, it will worsen the condition, therefore, nasopharyngeal cancer patients’ diet needs to be prudent. Dietary contraindications of nasopharyngeal cancer: 1. Pickled food, which is contraindicated food for nasopharyngeal cancer. Such as cured meat, salted fish, salted vegetables, etc., all contain nitrosamine, which may cause digestive tract tumor. It is found that the development of nasopharyngeal cancer is related to the frequent consumption of pickled food, like often eating cured meat, pickles, bacon, etc., in which nitrite will be transformed into nitrosamine and dinitroso-piperazine in the process of cooking, which will induce cancer. Nasopharyngeal cancer may develop at any age, and the youngest patient may only be in his teens, but its high incidence age group mainly focuses on around 40 to 50 years old. Therefore, it is suggested that nasopharyngeal cancer patients should eat less pickled food. 2.Can’t eat moldy food. Moldy peanuts, melon seeds or corn and other foods contain a lot of aflatoxin, which can induce nasopharyngeal cancer. Aflatoxin is a highly toxic and highly toxic substance. The harmfulness of aflatoxin lies in the fact that it has a destructive effect on human and animal liver tissues. In the natural contamination of food, to aflatoxin B1, the most common, its toxicity and carcinogenicity is also the strongest. 3, can not eat overnight vegetables. Containing a large amount of nitrite, after the use of the stomach can be combined with the protein, decomposition products into nitrosamines, which can easily lead to stomach and nasopharyngeal cancer. A large number of nitrites can make people directly poisoned, and nitrates in the body, can also be reduced to nitrites. Nitrite and human blood role, the formation of methemoglobin, so that the blood to lose the oxygen-carrying function, so that people are hypoxic poisoning. Serious will cause cancer.
