Nowadays, “cancer prevention” has become a topic of concern for everyone, but how can we most effectively keep “cancer-causing molecules” out of our bodies? Recently, researchers from Massachusetts General Hospital and Harvard University conducted a study on 135,000 people and found that among the factors that may cause cancer, the proportion of lifestyle factors, such as diet, smoking and exercise, accounted for 20% to 40%. Therefore, some experts say that cancer is mostly eaten out! So, what kind of dietary habits are prone to cancer? And how should people find and prevent cancer? 1, sugar – more than 25 grams is very dangerous Some people say that sugar will “nourish” cancer cells, although this statement is not accurate, but high sugar diet is indeed related to cancer. Swedish scientists have 80,000 people for up to nine years of follow-up, found that excessive intake of sugar, sweet drinks, jams and other foods will increase the risk of pancreatic cancer. Eating sugar will lead to a large amount of insulin secretion, so that the function of the pancreas is impaired, and become one of the potential factors to induce pancreatic cancer. And researchers at the MD Anderson Cancer Center in the United States found earlier this year that a typical Western diet with a high intake of sugar can increase the risk of breast cancer and cancer metastasis to the lungs. The World Health Organization recommends that daily sugar intake should be limited to 50 grams, preferably no more than 25 grams. 2, hot – 65 degrees is the temperature of cancer Chinese people especially pay attention to eat “while hot”, but the International Agency for Research on Cancer released a new study shows that the temperature of drinks in 65 ℃ or more drinks (such as coffee, tea, etc.) may trigger esophageal cancer. This is because, overheated food will damage the esophageal mucosa, long-term eating too hot food, mucosa repeated chronic damage, it may trigger chronic inflammation, which in turn increases the possibility of cancer. 3, lazy – fast food to eat 1 time, hurt 1 time Many people are too lazy to cook, like to eat ham, sausage and other processed foods, and some people are used to eating out, which can easily lead to excessive oil and salt intake, bringing the risk of cancer. The last meal hot, make do and eat is the norm for many people’s lives, but leftovers often have the risk of carcinogens nitrites. Eat on time, quantitatively, eat fresh food, try not to eat leftovers. In addition to this, lazy exercise will also increase the risk of cancer. 4, pickled – pickled products do not eat more dried fish, fish sauce, bacon, preserved sausage, pickles and other pickled food flavor unique, but such food often contains a large amount of nitrate, which will be transformed into nitrite in the stomach, and then combined with the amine in the food to become amine nitrite, which is highly carcinogenic and can lead to the stomach, intestines, pancreas and other digestive organs The chances of cancer are elevated. A report jointly published by the American Institute for Cancer Research and the World Cancer Research Fund shows that the consumption of processed meat products such as bacon raises the risk of cancer in the lower abdomen (such as colorectal cancer). Consuming 50 grams of processed meat products per day increases the risk of lower abdominal cancer by 18%. Most of these processed meats are prepared using marinades. It is recommended to eat fresh vegetables and meat as much as possible to reduce the intake of preserved food. 5, salty – a relative of cancer salt seems to be the most “dangerous” seasoning, eat too salty will lead to chronic damage to the gastric mucosal barrier, over time will increase the susceptibility to carcinogens, leading to stomach cancer. The number of people who die of cancer in a year is about 575,000 in the United States and about 365,000 in Japan. In terms of cancer mortality rate per 100,000 people, Japan is 1.6 times higher than the United States. This has to do with the fact that Japanese people eat an overly salty diet. People who eat heavy tastes can eat more fruits with vitamin C. Vitamin C can help block the synthesis of carcinogenic nitroso compounds. 6, smoked – containing strong carcinogens summer home more love to eat kebabs, a study found that often eat roast beef, roast duck, roast lamb and other smoked food, easy to get esophageal cancer and stomach cancer. Smoked food in the production will produce a large number of polycyclic aromatic hydrocarbons, strong carcinogens benzopyrene is one of them, it will cause cell mutation, triggering cancer. Eat less smoked food. 7, oil – good deep-fried can not Here “oil”, on the one hand, refers to high-fat food. Nature magazine recently released a research report shows that obesity, high-fat and high-calorie diet is a risk factor for many cancers. High-fat diet can drive the number of intestinal stem cells to proliferate indefinitely, and differentiate into other types of cells, easy to cause intestinal tumors. On the other hand, it refers to fried foods, such as doughnuts, fritters, and stinky tofu, which tend to produce polycyclic aromatic hydrocarbons (PAHs) when they are fried. Especially the oil from repeated frying has more carcinogens in it. Eat less fried food, often in the dietary supplement containing a balanced proportion of essential fatty acids fats and oils, with good fats metabolize the bad trans fatty acids and fats! 8, alcohol – drinking a limit A recent report in the United States shows that the risk of people suffering from stomach cancer is positively correlated with the amount of alcohol consumed: excessive alcohol consumption and liver cancer is closely related to the frequent drinking of beer or other alcoholic beverages, colon cancer incidence rate is high. China Cancer Foundation suggests: men drink no more than 20~30 grams of alcohol per day, and women no more than 10~15 grams. 9, mold – mold contaminated food Moldy food of course no one will intentionally eat. However, peanuts, corn, rice, sorghum and other foods are very susceptible to moisture, and thus contaminated by mold, sometimes not easy to be found, especially in the summer gazpacho, there are a number of moldy is also impossible to identify with the naked eye. Foods in this condition are likely to have carcinogenic effects of mycotoxins, which are one of the most carcinogenic substances known, and are extremely closely related to liver cancer. People learn to store food reasonably to prevent moisture mold. 10, smoke – frying fumes are the most easily ignored Smoking causes cancer has been a world consensus, in addition to quitting smoking, cooking fumes must also attract enough attention. Chinese dishes to fry, stir fry, deep frying and other high-temperature cooking methods, but we do not know, this practice is very easy to produce a lot of fumes, which is mixed with a lot of alkane substances and other carcinogens.
