Nutrition and Herbal Therapy for Cancer
Cancer has become a real threat to the present, while the specific drug to stop cancer cell growth has not been found. But prevention efforts continue to be endeavored with radiation therapy. Some people prefer alternative therapies because of the negative effects of radiation. In order to quantify the benefits and risks of alternative therapies, it takes an understanding of the workings of alternative therapies, including the use of dietary supplements (vitamins, minerals and antioxidants compounds) and herbal preparations that may work against cancer.
Various types of food were shown to contain anticancer substances. Even the stir-frymix of broccoli, tomatoes, cabbage, cauliflower, carrots, fish and meat is very rich in antioxidant elements. Also certain compounds such as allyl sulfides in garlic, curcumin in turmeric, isoflavones in soybeans, likofen in tomatoes, polyphenols in green tea, revesratrol in the skin of red grapes, and broccoli is a food sulforafan in cancer prevention. Some vitamins and minerals is also an antioxidant that is often promoted for cancer prevention: beta-carotene, vitamin C, E, and selenium.
For herbal therapies, there are many plants that based on empirical experience, it can fight cancer. Among these parasites (Dendrophtoe petandra), rose periwinkle (Catharanthus roseus), Polyanthum nirui L, white turmeric (Kaempferia rotunda L), and maitake mushrooms (Grifola frondosa).
Cancer cells will grow when normal DNA is damaged, causing genetic mutations. Ifthis is not immediately corrected, the multiplication of cells that DNA damage is a potential to produce cancer cells. Yet the multiplication of cells intended for therecovery of cells that are worn or damaged.
Two elements that can damage the DNA of normal cells are free radicals and carcinogens. Free radicals produced by metabolism or from the environment around us (plant waste, exhaust fumes, cigarette smoke, chemicals such as insecticides, chemicals or additives in food). Fortunately, free radicals can be bound and neutralized by several compounds, vitamins and minerals that are antioxidants.Antioxidant compounds that neutralize free radicals are polyphenols (green tea), likofen (tomatoes), beta-carotene (carrots), and several other compounds in vegetables or fruits.Especially on likofen in tomatoes, these compounds are strongly bound to the fiber fruit. To release, tomatoes must be cooked first with a little oil, given the nature likofensoluble in oil.Carcinogenic substances in food. This substance is actually derived from a procarcinogen by phase I enzymes in the liver is converted into a carcinogen. Meanwhile, phase II enzymes will remove product residue phase I enzymes, which can inhibit the formation of cancer cells. If the enzyme phase I enzymes that can be called evil, then the phase II enzymes are enzymes that good. Phase I enzymes can be inhibited by the compound was allyl sulfides in garlic so that changes can be reduced procarcinogen to a carcinogen. One example is the well-known carcinogen nitrosamine compounds produced combustion of meat / fish (eg charred skewers) and used cooking oil that has been used many times. Vitamin C acts as an antioxidant that inhibits the formation of nitrosamines in the digestive tract.
While the production of phase II enzymes can be enhanced by sulforafan which are often found in broccoli, cauliflower, and cabbage. Therefore, the menu consists of vegetables, broccoli, cabbage, cauliflower, carrots, tomatoes, and pan-fried fish a little oil and garlic is one of the menu options that are rich in antioxidant elements.
Inhibits Growth of Cancer Cells
If the damage to cell DNA can not be prevented by the compound or vitamin / mineral supplements that are antioxidants, or if already formed cancer cells, actions that we can do is inhibit the growth of cancer cells. Rapid growth of cancer cells after the cells are getting omega-6 fatty acids. To reduce the influence of fatty acids and expelled him from the cancer cells, omega-3 fatty acids are abundant in the cold sea fish has an important role. Omega-3 fatty acids are also known as EPA (eicosapentanoic acid) or gamma-lenolenat, is one of the essential fats.
Some types of cancer cells can grow rapidly when triggered by the human estrogen hormones, such as in breast cancer cells. In this case that the isoflavones in soy phytoestrogens was competitive with the human estrogen. So that consumption of soy isoflavones will help inhibit cancer growth induced by estrogen in humans. From this we can understand the role of soy beans, tofu and soy milk as food for the growth of cancer prevention.
To inhibit cancer cell metastasis, we need to know how the cell spread. There are two ways air-metastatic cancer cells: through angiogenesis (new blood vessel formation) and destruction of collagen, which is the framework of normal cells. As such metastases will be inhibited if angiogenesis can be prevented, while the collagen is damaged can be repaired by the body itself to take advantage of certain foods.
For angiogenesis, cancer cells release growth factors. Production of growth factors was found to be inhibited by cox-2 inhibitor preparations that included resveratrol in the skins of red grapes, curcumin in turmeric and genestein in soy.
Overhaul of collagen by cancer cells occurs with the help of the enzyme collagenase produced by cancer cells themselves.
Nutritional preparations that can hamper the reform process is vitamin C and shark cartilage. In addition to stimulating the formation of interferon join the fight against cancer cells, vitamin C was able to repair damage to collagen by creating new collagen by proline hydroxylation. Perhaps this is what underlies the role of controversial statements from a Nobel Prize winner in chemistry and peace, Linus Carl Pauling, regarding nutrition therapy of cancer with vitamin C megadose.
Forms of other nutrients that can help repair the collagen is shark cartilage is widely touted as a cancer drug. Indeed, shark cartilage is a source of collagen that can provide natural products for body cells to synthetic collagen.
