Medical experts remind: Seven dietary habits are easy to cause cancer!
The cause of cancer is still not fully understood, and many oncology theories such as genetics, virology, and environmental doctrine have been proposed.
In the past ten years, through epidemiology, nutrition surveys, clinical observations, animal experiments, etc., it is shown that about 70% to 90% of cancers are related to living environment, lifestyle and eating habits, and some foods are also found to have prevention. Cancer effect.
According to a large number of cases and data, the following foods or conditions are inseparable from carcinogenicity:
High fat foods are easy to cause cancer
When the high-fat diet is too high, the bile secretion is increased, and the intestinal bacteria can convert the bile component into a carcinogen, which has the effect of promoting the growth of the cancer and shortening the incubation period of the cancer.
According to the survey, the incidence and mortality of breast cancer, prostate cancer, colon cancer and rectal cancer are related to fat intake. Therefore, middle-aged and elderly people should promote a low-fat diet, both to prevent atherosclerosis and to prevent cancer.
Repeatedly frying oil is easy to cause cancer
Repeated frying oil is not suitable for eating. When the boiling point of oil reaches 221 ° C (lard) ~ 225 ° C (vegetable oil), complex chemical changes occur, resulting in aldehydes, ketones, low fatty acids, oxides and cyclization. Riveting and other harmful substances, people will dizziness, nausea, poor breathing, slow heart rate, high blood pressure and limb weakness, and long-term consumption may cause cancer.
Food is not easy to cause cancer
Frying over-fired foods, charred fish, meat, smoked or open-fired foods directly produce a lot of carcinogens.
Pickled foods are easy to cause cancer
The main component of salt is sodium chloride, but it also contains sodium nitrate and sodium nitrite. In the process of pickling food, it is contaminated by mold, and nitrosamine and nitrate are synthesized by mold. These salts are reduced to nitrite by intestinal bacteria and then react with amines in food to produce nitrosamines and cause cancer. Most of them are esophageal cancer and gastric cancer.
The peak time for nitrate production in pickles is the 20th day, and the fastest green vegetables can be produced in one day. But for more than a month, the nitrates can be destroyed, so unsalted pickles are less suitable.
Mildewed food is easy to cause cancer
Common molds in moldy foods include Aspergillus flavus, Penicillium, Fusarium. The most common foods such as moldy peanuts, beans and food are mostly Aspergillus flavus. It has a strong carcinogenic effect, more common as liver cancer, can also cause kidney cancer or gastrointestinal cancer.
Food additives are easy to cause cancer
Many processed foods in the market are supplemented with additives. It has been reported that preservatives, antioxidants, thickeners and artificial colors are all related to cancer, and should be strictly limited or not used in food processing.
Therefore, in order to make the food beautiful and stimulate the appetite, it is necessary to use a natural pigment such as chlorophyll, carotene, capsanthin or the like as a harmless pigment. In addition, artificial sweeteners such as saccharin and sweetener have been tested in animals and have been shown to be carcinogenic and should not be used or used frequently.
Drinking a lot of alcohol is easy to cause cancer
Long-term heavy drinking can lead to chronic alcoholism, cirrhosis, and increased risk of liver cancer. Drinking hard alcohol often increases the chances of developing oral cancer, esophageal cancer and stomach cancer. Cigarettes have carcinogens, and drinking while smokers are more unhealthy.
