How to prevent pancreatic cancer? Qian Zhenghong, an attending physician in the Department of Gastroenterology and Hepatobiliary Surgery, said that in addition to family history and genetic inheritance, the risk factors for pancreatic cancer are mainly related to smoking, drinking, obesity, high-fat diet and diabetes. In 2021, there was an American study published in the journal Cancer Epidemiology on whether eating cruciferous vegetables could reduce pancreatic cancer. The results showed that eating more than 1.5 servings of “raw” cruciferous vegetables per week was the highest. 40% lower risk of pancreatic cancer.
Qian Zhenghong explained that the study found 183 pancreatic cancer patients and 732 healthy people as a control group. The average age of the two groups was 61 years old, and 53% were male. Then, the daily life of the two groups was recorded by questionnaires. eating habits, and then compare the differences between the two groups.
Qian Zhenghong added that the “cruciferous vegetables” referred to in the study refer to cauliflower, cabbage, cabbage, kale, kale, broccoli and white radish. The statistical results showed that the pancreatic cancer group ate less cruciferous vegetables, 3.4 servings per week lower than the healthy group 4.1 servings, and the pancreatic cancer group ate more meat, 8.4 servings per week higher than the healthy group 7.1 servings .
Eating more than 1.5 points per week of raw cruciferous vegetables can reduce pancreatic cancer risk by up to 40%
Consuming more than 1.5 servings of “raw” cruciferous vegetables per week can reduce the risk of pancreatic cancer by up to 40%. Each additional serving of “raw” cruciferous vegetables was associated with a 15 percent higher risk of pancreatic cancer, and an additional serving of “cooked” vegetables was associated with an additional 8 percent lower risk.
Continued smoking, severe obesity, and eating cruciferous vegetables do not reduce cancer risk
People who have quit smoking eat more than 4.5 servings of cruciferous vegetables per week and can reduce the risk of cancer by 50%. Continued smokers ‘failed’ to reduce cancer risk by eating cruciferous vegetables Moderately obese (BMI 25 to 30), eating one extra serving of vegetables per week can reduce cancer risk by 20%. Severely obese (BMI>30) eat cruciferous vegetables “cannot” reduce cancer risk.
Cruciferous vegetables may prevent pancreatic cancer, colorectal cancer
Qian Zhenghong explained that the anti-cancer effect of cruciferous vegetables may be due to smoking, drinking, and high-fat foods that increase the secretion of bile acid in the liver. Excess bile acid will enter the pancreatic duct and induce the formation of cancer cells when it passes through the pancreas. Vegetables have the ability to bind bile acids, which can help the intestinal tract reduce the recovery of bile acids. In addition, vegetables are rich in antioxidants such as isothiocyanate, leucine and glucaric acid, which can assist in the conversion of secondary bile acids and metabolism. Remove the toxicity of the substance, reduce its damage to the pancreas and intestinal mucosa, and prevent pancreatic cancer and colorectal cancer.
When eating lettuce, be sure to wash the vegetables and eat them fresh to avoid eating poisons and germs.
Since the isothiocyanate structure will be destroyed when heating vegetables, the anti-cancer effect will inevitably be discounted, which is also the reason that the anti-cancer effect of “raw food” vegetables is better than “cooked food”. Qian Zhenghong added that as a gastroenterologist, he does not encourage people to eat raw food often. After all, raw food can easily eat poisons and germs, causing liver and gallbladder and gastrointestinal infections, especially for those with weak immunity or the elderly.
Qian Zhenghong said that although the anti-cancer effect of cooked food is lower than that of raw vegetables, it will still be beneficial to eat more. It is recommended that if you want to eat lettuce, wash the vegetables and eat them fresh. You don’t need to eat too much. More than 1.5 servings per week is very effective.
In addition, studies have observed that even for people who have smoked or are moderately obese, eating more vegetables still has an anti-cancer effect, but if they continue to smoke, eating more vegetables will help to a limited extent. It is more practical to find ways to quit smoking and lose weight!
