"Two Fruits and Five Vegetables" is a relatively reasonable dietary structure suitable for the general public. People should improve their unhealthy eating habits, avoid eating some non-fresh and overly processed foods, which is beneficial to the body. Most cancer patients are affected by their eating habits, so everyone should still eat healthily to prevent cancer.
For the general public, the first thing is to prevent "cancer from entering through the mouth". Professor Zhang Guangchao introduced that this year's new fruit and vegetable recommendation for World Cancer Day is to consume 2 servings of fruits and 5 servings of vegetables daily—the increase in the recommended amount of fruits and vegetables is a reminder for people to promptly reflect on and adjust their nutritional structure. Research shows a certain correlation between dietary patterns and the risk of specific cancers. Daily consumption of fruits or vegetables (80-100 grams) can reduce the risk of oral cancer by 20% and stomach cancer by 30%. High fiber intake (an average of 27 grams per day) can reduce the risk of colorectal cancer by 20%. However, red meat and processed meat products increase the risk of colorectal cancer, and high salt intake and pickled foods increase the risk of stomach cancer.
Many young people buy a large number of processed, easy-to-store foods at the supermarket at once, filling their refrigerators, and then stay at home for several days without going out. Unbeknownst to them, it is such a lifestyle that gives digestive tract tumors an opportunity.
Professor Cai Sanjun from Fudan University Shanghai Cancer Center pointed out that the freshness of food is an important factor in ensuring gastrointestinal health. In pickled foods, there are substances that can cause cancer—nitrosamines, and high concentrations of salt can seriously damage the gastrointestinal mucosa. Therefore, people who often eat pickled foods are prone to gastrointestinal inflammation and ulcers, which are high-risk factors for the development of digestive tract tumors; processed meat products (such as sausages) contain carcinogenic nitrites, and the added preservatives, color enhancers, and color fixatives add to the burden on the human liver; don't underestimate small snacks like preserved fruits, candied plums, and preserved fruits, they also contain nitrites, which can combine with amines in the human body to form potential carcinogenic nitrosamines. "Therefore, freshness should become the constant 'main theme' on our dining table."
Professor Cai Sanjun emphasized that an unhealthy dietary structure is also an important factor in digestive tract tumors. A diet high in protein and fat, and low in fiber is closely related to colorectal cancer. Therefore, we need to prevent cancer by changing our lifestyle, thereby greatly reducing the incidence rate.
"Two Fruits and Five Vegetables" can help people eat healthily and stay away from cancer. If the dietary structure is scientific and reasonable, and the eating habits are relatively healthy, I believe many diseases will stay away from you. The above suggestions are hoped to remind everyone, people with poor eating habits need to pay attention to food hygiene issues and should correct it in the future.
