a few days ago, colleague Xiao Li sent a link to ask: Xiao AI, this article said eating ginger can cause liver cancer, is it true?
. The title is “eating too much ginger can cause liver cancer”. Xiao AI is impressed with the news. It was hotly discussed several years ago, but now the rumor has appeared again. Xiao AI thinks it is necessary to talk to you again.
eating ginger can cause liver cancer, is it true?
before answering this question, Xiao AI will show you the news:
image source: Guangming network
news clearly pointed out??: adding 0.04% ~ 1% safrole to the feed of mice for 150 days to 2 years can induce liver cancer in mice. Does this mean that if people eat ginger containing safrole, they will get liver cancer? I don’t think so. There are three reasons:
. First, safrole is the source of ginger cancer, but safrole may not necessarily cause cancer.
are natural flavors, mostly found in ginger, cinnamon, nutmeg, Rolle and other spices. In addition, it is also used in food additives and cosmetics.
since the 1960s and 1970s, some researchers have doubted the safety of safrole, and have done animal experiments. The results show that safrole can cause permanent damage to the liver of many animals. Since then, the food and Drug Administration (FDA) has banned safrole in food and drink. In 1994, safrole was approved to be used again. On October 27, 2017, the international agency for research on cancer of the World Health Organization added safrole to the list of class 2B carcinogens, that is, safrole may cause cancer to human body, but there is no evidence to prove its carcinogenicity.
. Secondly, there are still some differences between animal experiments and human experiments.
have checked a lot of research literature, and found no conclusion that safrole causes human liver cancer. All the “safrole carcinogenic” conclusions are based on mice and rats, but in fact, there are some differences between animal experiments and human experiments. Third, ordinary people don’t eat too much ginger. “Excessive consumption of ginger increases the risk of liver cancer,” the article
.” To be sure, “Ginger addiction” does not exist. Ginger is not a delicious food. Who will eat one or two Jin at a time, so the possibility of excessive is very low.
is it possible: eat less ginger but overdose safrole?
as early as 2002, the health and Consumer Protection Council of the European Commission made a regulation on safrole intake. The allowable dosage of safrole in food is 2mg / kg, and the daily intake of safrole is roughly estimated: no more than 1mg per person per day.
were analyzed. It was found that the safrole content of cardamom nutmeg was 138ug / G after purification, and about 5g of purified product could be obtained from a Jin (500g) cardamom. It can be inferred that the safrole content in a catty of Cardamom is about 700ug. If you want to reach the daily intake limit set by the European Commission, you should eat nearly one and a half catties of cardamom every day, and ensure that it is fully absorbed. Few people can do it.
based on the above three points, Xiaoai can say for sure that normal eating ginger does not have to worry about cancer.
three types of people really should not eat ginger.
traditional Chinese medicine believes that ginger has the effect of sweating and relieving the exterior, warming the middle and stopping vomiting, warming the lung and relieving cough. Therefore, it often appears in the prescriptions for relieving vomiting and relieving exterior symptoms, but in fact, the following three categories of people are not suitable to eat ginger.
people with Yin deficiency constitution: the characteristics of yin deficiency constitution are that the whole body is dry and hot, the palms are sweating, they often feel dry and thirsty, their skin is dry, they are upset and irritable, and they are easy to wake up when they sleep. Traditional Chinese medicine believes that “heat and cold”, and ginger Xinwen, yin deficiency people eat will aggravate the disease.
with severe internal heat: people with halitosis, hemorrhoids bleeding, lung heat dry cough, stomach heat vomiting, sore ulcers and other diseases should not eat ginger. These diseases belong to fever, and should not eat hot ginger.
hepatitis patients: ginger is hot, excessive consumption can easily cause liver fire. If you want to control the liver fire caused by eating ginger, you can take some liver soothing and Qi regulating foods at the same time, such as hawthorn and chrysanthemum, which can clear the dry heat and won’t hurt the body.
two points for attention in eating ginger
1. To control the consumption of ginger,
ginger can not only seasoning, but also has certain nutritional value, but also pay attention to the intake. As mentioned above, excessive intake of ginger is easy to cause liver fire, and ginger is spicy. Excessive intake will cause irritation to gastric mucosa, especially for people with inflammation. Excessive consumption of ginger during inflammation will aggravate the disease. Do not eat
2. Rotten ginger is easy to rot if it is not stored well. The safrole content of rotten ginger will double, so it must not be eaten.
therefore, the so-called “eating ginger causes liver cancer” is not correct, but we can not eat it without scruple. Any food is “too much than it is”. Put two pieces of ginger in each stir fry or soup, which can bring its maximum value into full play.
