Cancer research has produced dietary guidelines over the last twenty-five years. This guidelines have become conventional wisdom when it comes to cancer prevention. Among the most common of these guidelines are :
Reduce unhealthy dietary fat. Since fat cells split apart easily, they contribute to a high population of free radicals, the molecular fragments which tear at the cell’s membrane, and in some cases, damage the cell’s DNA structure. When the DNA structure is interfered with, mutation can occur, which leads to the formation and growth of cancerous cells. It is recommended that you limit fat to 30 percent or less of your caloric intake. However, according to the Harvard School of Public Health, studies have shown that what is most important is not the amount of fat in the diet, per se, but the type of fat. Thus, the latest advice is to cut out the unhealthy fats – saturated fats and trans fats. See How does reducing unhealthy fat in my diet lower my risk of cancer? for ideas on how to reduce unhealthy fat in your diet.
Cancer has grown as death full disease and it could attack on everyone, any gender in any age. To prevent it we must pay attention on our habits eating.
Here are rules that you must follow as healthy diet for cancer prevention :
Eat at least five servings of fruits and vegetables each day
A recent report sponsored by the World Cancer Research Fund and the American Institute for Cancer Study estimated that eating 400 or more grams daily of fruits and vegetables could prevent at least 20 percent or more of all cancers. In addition, those who eat the highest amount of fruits and vegetables have been shown to have one half the cancer risk as those eating the least amounts. (more…)
Substantial information exists about the links between certain types of cancers and nutrition. It is important to note that other lifestyle factors, such as smoking, alcohol use, exercise level and obesity also play a role in the risk of developing cancer. The list below details common cancers and dietary choices which aid in prevention or increase the risk of the disease.
Lung Cancer – This is the leading cause of death from cancer in the world and smoking is mostly responsible. There is convincing evidence that diets high in vegetables and fruits are protective against lung cancer and that compounds called carotenoids, which are present in significant amounts in these foods, are probably responsible for some of this effect. However, the use of antioxidant supplements, such as beta-carotene and vitamin E, has not been proven to be effective in either prevention or treatment of lung cancer and may, in fact, increase the risk of developing cancer in those who smoke.
Certain foods have come to the forefront in the past few decades of cancer research as heavyweights in the battle against cancer. The National Institute for Cancer Research presents an all-star line up of foods known for their effective cancer-fighting properties:
Beans (or legumes), which include lentils and peas, are rich in fiber and contain several chemicals that boost immunity to cancer. Saponins have shown the ability to inhibit the growth of cancer cells in different tissues; protease inhibitors slow down cancer cells from multiplying and suppress proteases, potent cell destroyers; and phytic acid slows the growth of tumors. A study of 3,237 men of different ethnic backgrounds showed that the risk for prostate cancer was 38 percent lower in those who ate the most amount of beans, as compared to those who ate the least amount.
