The causes of malignant tumors are the result of long-term combined effects of multiple factors, mainly including environmental factors, human immunity, metabolic function, and genetic factors. Diet is also one of the factors that can cause cancer. "However, regardless of anything else, a scientific and balanced diet and a healthy lifestyle are necessary conditions for maintaining good health," experts say. "We should also eat more fresh vegetables and fruits in our daily lives, which can supplement the immune capacity of our body's immune cells."
New medical research now shows that genes also have a significant impact on cancer. "Therefore, citizens should develop the habit of regular health check-ups. Some diseases need to be detected and treated early, especially for citizens with a family history of disease, who should pay more attention to these issues."
Three types of foods on the cancer 'black list'
1. Barbecued food: The fat in grilled meat contains various carcinogens
When grilling over an open flame, the fat from the grilled meat dripping onto the hot charcoal produces carcinogenic polycyclic aromatic hydrocarbons, including more than 400 carcinogenic compounds such as benzopyrene and tetramethylbenzene. Some of these carcinogenic compounds enter the human digestive tract through the grilled meat, and some enter the human respiratory tract through the smoke from the barbecue. After these carcinogens accumulate in the body, they can induce stomach cancer, intestinal cancer, breast cancer, colon cancer, etc. Relevant data shows that women who often eat barbecue have twice the chance of getting breast cancer compared to women who do not eat barbecue food.
To eat barbecue healthily, first, choose the correct grilling method, such as using a stove or electric grill. Second, eat less fatty meat. You can grill it with the skin on, but you should remove the skin before eating. The burnt parts must not be eaten because they contain the most carcinogens. Many people like to drink a few glasses of ice beer while eating barbecue, which also increases the absorption of carcinogens invisibly.
2. Puffed food: Eating too much can easily lead to excessive heavy metals
Popcorn may be the earliest puffed food people ate, but many people don't know that popcorn made in a high-temperature, sealed lead pot will contain a lot of lead after it's cooked. Puffed foods contain heavy metals for two reasons: first, processing such foods often requires adding additives such as leavening agents; second, the food is processed through metal pipes, which usually contain lead-tin alloys. At high temperatures, the lead can easily vaporize, and the vaporized lead then contaminates the puffed food.
Frequently eating puffed food is very harmful to children. Lead will slowly accumulate in the blood and bones and is difficult to be metabolized naturally. When harmful heavy metals accumulate to a certain level, they will cause obvious damage to the human body's nervous, digestive, and hematopoietic systems, and can especially lead to cognitive impairment or a decline in thinking ability.
In pursuit of taste, some puffed foods are coated with hydrogenated oils on the surface. The longer the baking time and the higher the temperature, the more trans-fatty acids are produced. Trans-fatty acids can be harmful to the human body and can ultimately lead to an increased incidence of obesity, cardiovascular and cerebrovascular diseases, diabetes, bronchial asthma, allergic rhinitis, some malignant tumors, dementia, etc.
3. Fried food: Makes you sick and affects your mind
When the oil used for frying food is used many times, it becomes what we commonly call 're-boiled oil'. Re-boiled oil contains a large amount of trans-fatty acids, which can cause great harm to the human body, such as fatty liver, high blood pressure, cholecystitis, stomach diseases, diabetes, obesity, and it may even increase the risk of cardiovascular and cerebrovascular diseases and various cancers.
Youtiao (fried dough sticks) are a favorite breakfast for many people. However, in pursuit of taste, some unscrupulous operators will add leavening agents containing potassium aluminum sulfate or ammonium aluminum sulfate to the youtiao. If you eat too much food containing this leavening agent, it is most likely to damage brain tissue and may lead to senile dementia.
