Trace elements are the center of many activities in the human body, such as enzymes, hormones, and vitamins. They have very important physiological functions. Once trace elements are deficient or imbalanced in the human body, they can cause various changes in physiology and biochemistry. Symptoms or some kind of disease. Among them, the trace elements selenium, iron, iodine, and molybdenum have very important anti-cancer and anti-cancer effects, and are therefore regarded as the “four major diamonds†that protect the human body.
Selenium, an indispensable trace element in the metabolism of the heart, is known as the "fire of life." If the human body lacks selenium, it seems to have lost a solid defense against cancer. Selenium is also an important part of the body's peroxidase enzyme. This enzyme not only prevents the oxidation of unsaturated fatty acids but also inhibits the formation of carcinogenic peroxides and free radicals. Scientists believe that the function of selenium through phagocytic cells can influence the energy metabolism of cancer cells and interfere with the protein synthesis of cancer cells, thereby inhibiting cancer, and can also affect the metabolism of chemical carcinogens, causing them to lose their carcinogenic activity.
After investigating the relationship between cancer mortality and selenium intake per person in 20 countries, the scientists found that selenium intake was low, and cancer incidence and mortality increased, especially colon cancer, pancreatic cancer, and ovarian cancer. The most obvious are lung cancer and skin cancer in men, prostate cancer, and men. Selenium-rich foods are the first choice for sesame seeds, malt, and Chinese medicinal materials, astragalus, followed by yeast, eggs, and beer. Seafoods such as red shrimp, lobster, tigerfin fish, tuna, etc. are better. Once again, they are liver and kidney meat. In the category, fruit and most vegetables contain less selenium, but the contents of garlic and mushrooms are quite large. Asparagus also contains a lot of selenium. As for dairy products, the variation in selenium content is relatively large.
Iron, which is the main raw material for hemoglobin in erythrocytes, is also essential for the transport and exchange of oxygen in the blood, and it is also the active site of many enzymes. In the absence of trace element iron, it is generally associated with esophageal and gastric tumors, and people who lack iron often have previous lesions of gastric cancer. Studies have found that the lack of iron can lead to chronic atrophic gastritis, making gastric acid too low or lacking, which in turn allows bacteria to accumulate, leading to the formation of carcinogenic nitrous ammonium in the stomach. By the same token, the risk of gastric cancer in sub-anaerobic patients will also increase. However, the amount of micronutrients as nutrients can only play a role within a moderate range, and lack of or excessive amounts of them are detrimental to human health.
A team of researchers led by the famous epidemiologist Carter Dijk Weiss studied more than 8,000 participants and found that high iron concentrations in human blood are prone to tumors, indicating that too much iron is also a risk factor for cancer. . The researchers pointed out that iron is not only one of the essential trace elements in the human body, but also an important ingredient in diet, cancer prevention and anti-cancer. It should receive enough iron from food to meet the needs. It is really necessary to supplement iron. Under the guidance of a doctor. Foods containing more iron include animals' livers, bone marrow, sesame seeds, black fungus, malt, and spinach. Cooking rice dishes with wok and cooking are also great advantages of iron supplementation.
Iodine, an important component of thyroxine, activates more than 100 enzymes and plays an important role in the physiology of the thyroid gland and in promoting protein synthesis. Iodine deficiency can cause hypothyroidism, which is accompanied by imbalances and disorders of thyroid hormones, prolactin, sex hormones. The lack of iodine in the diet is not only associated with thyroid enlargement and endemic thyroid tumors, but can also increase morbidity and mortality of thyroid tumors. Iodine deficiency is also one of the causes of breast cancer, endometrial cancer and ovarian cancer in women. Iodine deficiency can also lead to poor development of mammary epithelial cells. This change can be exacerbated by estrogen and progress to preneoplastic or tumorous conditions. Once supplemented with moderate inorganic iodine, this change can be reversed, which further confirms The relationship between iodine deficiency and cancer. Foods containing more iodine include seaweed, seaweed, shrimp, jellyfish, seaweed, yellow croaker, and iodine-containing salt.
Molybdenum is an important part of human metalloenzymes. If it is too much, it is more likely to suffer from stroke, knee inversion, osteoporosis, etc. However, the lack of molybdenum will cause kidney stones and dental caries as well as esophageal cancer. . Studies have shown that the incidence of esophageal cancer is inversely related to the content of molybdenum in the local soil and the content of a series of other inorganic salts. In areas of high incidence of esophageal cancer, people have the lowest level of molybdenum in hair, which is related to the lack of molybdenum in the local soil and water. Molybdenum, a trace element that can prevent the synthesis of carcinogen nitrite, is found in cabbages and cabbages. Others, such as various types of beans, grains, carrots, and radish, also contain more molybdenum. In general, the finer the food, the smaller the molybdenum content. Therefore, you should eat natural food. If you can eat raw food, try to eat as much as possible. This will be more beneficial.
