Unfortunately, science has not yet shown us a specific diet that prevents cancer. One of the main problems with the Diet Cancer Association is that it is very complex. Cancer that affects a specific area, such as breast cancer can be controlled by different biological mechanisms, so that although it is breast cancer, diet or treatments to which breast cancer especially calls to be quite different
During my short stay as a medical student, I had a professor in oncology pathology. He has always talked about “Bingo against Cancer” in the sense that there are a number of factors that affect cancer: genetics (a big one), nutrition, environmental pollution and so much more. It was not needy every element that would reason definitely cancer, but the union of different appointed elements that would then cause cancer.
This makes it very difficult to study. If you are worried about developing or fighting particular cancer, it is important to analyze this cancer and the treatments it responds to exactly.
For example, some types of breast cancer for sensitive insulin and therefore the consumption of a lot of carbohydrates would (ironically, like a vegan diet) cause the body to produce insulin, which is an ineffective strategy to reduce the risk of certain types of cancer.
Fight against cancer
In 1970, the British doctor Dennis Burkitt observed that a diet rich in fiber reduced disorders of the digestive tract. He noted that (eg herbal diet) has fewer cases of colon cancer in countries where the diet is high in fiber. It has happened all over the world. The highest fiber intake is found in non-industrialized countries, where meat is scarce and plant foods are on the menu. Animal products do not contain fiber. The United States UU and other western countries whose diet is based on animal products have the highest rates of cancer.
While no one is sure how fiber protects against digestive tract disorders, there are several options. By definition, fibers cannot be digested by humans at the beginning of the digestive process. It transports food through the intestine faster and helps eliminate carcinogens. It also draws water into the digestive tract. Water and fiber make the fecal matter larger so that carcinogens are diluted.
Bile acids are excreted in the intestine to help digest fats. There, bacteria can turn acids into chemicals that promote colon cancer. The fibers can bind to these bile acids and remove them from the gut.1 In addition; the bacteria in the colon ferment the fiber, creating a more acidic environment that can make bile acids less toxic.
Fiber also protects against other forms of cancer. Studies have shown that gastric cancer and breast cancer are less common in high-fiber diets.23 Dietary fiber influences estrogen levels in the body. Estrogens are generally secreted in the entrails, where the fibers incur to the hormone and take aside it from the body. 4 accept the good fibers; estrogen can be absorbed by.4 without the good fibers; estrogen can be absorbed by the intestine into the bloodstream. High levels of estrogen are associated with an increased risk of breast cancer.
In the United States, the average daily fiber intake is 10 to 20 grams per day. Experts recommend 30 to 40 grams a day. The best sources of fiber are whole grains, beans, peas, lentils, vegetables, and fruits. The foods closest to their natural state, unrefined and unpeeled, are the richest in fiber.
The Meaning of Vegetables
There are not only low-fat, high-fiber vegetables, but also many substances that fight cancer. Carotenoids, the pigment that gives fruits and vegetables their dark colors, have been shown to help prevent cancer. Beta-carotene, found in dark green and yellow vegetables, protects against lung cancer and can help prevent cancer of the bladder, mouth, larynx, esophagus, breast and other sites.
Vegetables for example cabbage, kale, cauliflower, broccoli and Brussels sprouts contain flavones and indoles, which are believed to work versus cancer.
Vitamin C found in citrus fruits and many vegetables can reduce the risk of cancer of the esophagus and stomach. Vitamin C acts as an antioxidant and neutralizes the carcinogen and formed in the body’s chemicals. It also blocks the conversion of nitrates to carcinogenic nitrosamines in the stomach.
Selenium is present in whole grains and has the same antioxidant effects as vitamin C and beta-carotene. Vitamin E also has this effect. Caution is advised when supplementing with selenium, which is toxic in high doses.
Vegetarian Diets and Overall Cancer Risk
Relatively few prospective studies have examined the relationship between vegetarian diet and cancer risk. For most meat-free diets, they seem to have at least modest protection against cancer in most, but not all, reports (10 to 12% reduction in risk), but the results are less clear for some cancers. This lack of clarity may be related to the heterogeneity of vegetarian diets as they can vary considerably with respect to the relationship between animal and plant foods, the quality of foods and the limitations of the quantification measures of the diet. Food intake and other lifestyle and environmental factors that may influence cancer risk in the populations studied. For example, a semi-vegetarian who replaces most portions of pork with portions of chicken and fish has a very different nutritional composition compared to a vegetarian who consumes cheese or eggs in most meals or a vegan who consumes only food from vegetable sources. The total nutrient content of plant protection depends on the total amount of plants consumed. In addition, large prospective nutritional studies are generally based on a single or rare food frequency questionnaire (FFQ) to characterize the nutritional pattern of a person over several years. Even if the FFQ is a perfect measure of the nutritional profile, which is not the case, it is very likely that the way a person eats is stable over several years.
