At a warm family dinner, Aunt Zhang whispered to her nephew: "Xiao Li, don't eat so much chicken, I heard that it is the 'hair of a tumor', which is very dangerous." Uncle Zhang next to him also joined the discussion: "Yes, I heard from a friendThe same goes for duck and fish, which can accelerate the growth of cancer cells. Such conversations are not uncommon in our daily lives. But what is the truth?
Tumors, a common disease of this era, are not only influenced by genetic and environmental factors, but diet also plays a key role. Research in recent years has revealed a strong link between diet and tumor development. For example, high-fat, high-sugar dietary Xi has been shown to be associated with the incidence of many cancers. This does not mean that all foods high in fat or sugar directly cause tumors, but long-term poor dietary habits do increase Xi risk.
Tumor cells need energy to grow and develop, and a large part of this energy comes from food. Certain food components, such as excess refined sugar, may provide additional energy to tumor cells, thereby accelerating their growth. A study by the American Institute for Cancer Research pointed out that excessive intake of processed meat, red meat, etc., may increase the risk of colorectal cancer. On the other hand, dietary fiber is thought to reduce the risk of certain types of cancer, as they help maintain gut health and reduce the retention time of harmful substances in the gut.
It is important to note that the effects of diet vary from person to person. Genetic factors, lifestyle, and overall health can all affect the specific effects of food on an individual. For example,A study published in the journal Cancer Epidemiology, Biomarkers & Prevention found that people with certain genetic variants may be more susceptible to high-fat diets.
For a long time, there have been many misunderstandings about the relationship between cancer and diet, especially whether meat is the "hair product" of cancer. In fact, meat foods such as chicken, duck, fish, and meat are not the main culprits that directly promote the occurrence of tumors. Scientific studies have shown that nutrients such as protein, vitamins and minerals in meat are essential for human health.
When it comes to understanding the relationship between meat and cancer, the key lies in how much and how it is consumed. A study published in the Journal of Nutrition showed:Moderate meat intake is beneficial for the human body, especially fish and poultry, which provide high-quality protein and essential fatty acids. Excessive consumption of processed meats, such as sausages and bacon, may increase the risk of certain types of cancers.
For example, a study by the World Health Organization states that a daily intake of 50 grams of processed meat may increase the risk of colorectal cancer by 18%. This does not mean that these foods must be avoided altogether, but rather emphasizes the need to eat a balanced diet and limit the intake of processed meats.
For cancer patients or high-risk groups, choosing lean meats and reducing the intake of red and processed meats can better control the risk. At the same time, the cooking method is also important. For example, substances such as polycyclic aromatic hydrocarbons and heterocyclic amines, which are produced when grilling or frying meat, are thought to be associated with an increased risk of cancer. On the contrary, low-temperature cooking methods such as steaming and stewing are healthier.
Modern scientific research has revealed that certain foods may accelerate the growth of cancer cells. These foods are ubiquitous in the daily diet, but their potential risks are often overlooked. Here are five foods that may promote the growth of cancer cells, along with scientific explanations and recommendations.
Processed meats: including sausages, bacon, ham, etc. Studies have shown that the preservatives and additives in these meats, such as nitrites, may contribute to an increased risk of cancer. For example, the World Health Organization has shown that a daily intake of 50 grams of processed meat may increase the risk of colorectal cancer by 18%. It is advisable to choose fresh, unprocessed meats.
High-sugar foods: High-sugar foods can quickly raise blood sugar and promote insulin secretion. Too much insulin stimulates cell growth, including cancer cells. For example, sugar-sweetened beverages have been linked to an increased incidence of certain types of cancer. It is advisable to reduce sugar intake and choose naturally low-sugar foods, such as fresh fruits.
Excessive red meat: Frequent intake of large amounts of red meat (beef, lamb, etc.) is associated with an increased risk of certain cancers. The heme iron in red meat can damage intestinal cells, leading to DNA damage. Moderate intake of red meat, along with increased intake of vegetables and whole grains, can help reduce your risk.
Trans fats: Trans fats, found in some baked goods and fast food, may increase the risk of cancer. Trans fats cause inflammation and cellular variation. Choosing foods that are low in fat and free of trans fats is a healthier choice.
Excess salt: Excessive salt intake is associated with an increased risk of stomach cancer. High levels of salt can damage the gastric lining and increase the likelihood of cell mutation. Reducing salt intake, especially hidden salts in processed foods, has health benefits.
In the long-distance race of cancer prevention, diet plays a role that cannot be ignored. Scientific studies have shown that certain foods contain ingredients that can reduce the risk of cancer, and that small changes in daily life can make a big difference. Here are some simple and practical dietary tips to help build healthy eating Xi that can help reduce your cancer risk.
Vegetables and fruits are an important part of the diet. They are rich in vitamins, minerals, and antioxidants, which are essential for cancer prevention. For example, lycopene in tomatoes and vitamin C in citrus fruits have both been shown to help reduce the risk of certain types of cancer. It is recommended to consume at least five servings of vegetables and fruits a day and have a variety of them.
Whole grains are high-quality carbohydrates** and are healthier than processed and refined grains. itWe are rich in fiber, which can help maintain gut health and reduce the risk of bowel cancer. For example, oats, brown rice, and whole-wheat bread are great options. Replace white rice and bread with white bread as much as possible in your daily diet.
The right amount of healthy fats is just as important. Unsaturated fatty acids in foods such as fish, nuts, and olive oil are beneficial for cardiovascular health, while also helping to reduce the risk of certain types of cancer. For example, one study showed that regular consumption of deep-sea fish, such as salmon and mackerel, could reduce the risk of colorectal cancer.
It's also important to limit your intake of processed and red meat. Some of the compounds in these foods can produce carcinogens during high-temperature cooking. For example, studies have shown that regular consumption of processed meats such as sausages and bacon is associated with an increased risk of stomach and colon cancer. Fish, poultry and legumes are recommended as the main proteins**.
Staying most hydrated is essential for maintaining good health. Adequate water intake helps boost metabolism and remove potential carcinogens from the body. It is recommended to drink at least eight glasses of water a day while reducing your intake of sugary drinks and alcohol.
