Some foods and herbs contain compounds and properties that can fight some cancers such as prostate cancer, lung cancer, stomach cancer, and more. Research has revealed that some foods have great potential to prevent or reduce the risk of certain cancers than other foods.
As reported Prostate.com, Sunday (3/18/2012), here are 10 foods that are clinically proven effective against cancer.
A. Bean
Peanut is the best source of vegetable protein and contains a fairly good fiber content. Researchers at Colorado State University have discovered the ability of anticancer contained in the beans. Reddish white beans have anti-cancer effects are greater than the bluish color. More colored beans have a lighter effect.
In another study, researchers monitored the eating habits of 490,000 people over and compare it with the risk of cancer of the mouth, throat and larynx. The result, a very powerful food protects against cancer include beans, carrots, and tomatoes.
2. Vegetables like broccoli and similar vegetables
Broccoli and similar vegetables such as cabbage, cauliflower, cabbage, and kale contain powerful cancer-fighting compounds. Compound is indole-3-carbinol (I3C) and diindolylmethane (DIM). I3C and DIM increases the metabolism of estrogen to be more secure. The hormone estrogen is known to trigger cancer.
Broccoli sprouts are also a source of sulforaphane, a phytochemical that has been shown to increase the production of cancer-fighting enzymes. Two other compounds are cancer-fighting lutein and zeaxanthin are also found in vegetables. Lutein has been shown to fight prostate cancer and colon cancer.
3. Carrots
Carrots are a source of beta-carotene, a powerful antioxidant that is proven to reduce the risk of various cancers, including prostate cancer, mouth, throat, colon, stomach, and bladder. A study of urologic found that consumption of carrots and vegetables associated with decreased risk of bladder cancer.
A study conducted the National Cancer Institute also confirmed carrots help reduce the risk of cancer of the mouth and throat. In addition to beta-carotene, carrots also have anti-cancer substances called falcarinol. Several studies have found that beta-carotene increases lung cancer risk, but this study used beta-carotene supplements and the highest risk found in smokers.
4. Cayenne pepper
Red peppers contain capsaicin, a substance that has the ability to fight cancer in several parts of the body. In a research laboratory in 2007, capsaicin proved to slow the growth of prostate cancer cells and promote cancer cells to commit suicide.
Lung cancer is common in men. Researchers at Marshall University in West Virginia recently discovered that capsaicin is useful in the treatment of lung cancer cells. Capsaicin also plays an important role to fight against stomach cancer.
5. Garlic
Garlic contains allium compounds which may enhance the activity of the immune system that is designed to fight cancer. The compound, called sultides dialyl and capable of blocking the entry of carcinogens into the cells, as well as slow the progression of tumors. People who regularly eat raw or cooked garlic will lose half the risk of stomach cancer and two thirds the risk of colorectal cancer, according to a study published the American Journal of Clinical Nutrition.
In a study from China, researchers found evidence that a compound derived from garlic, called S-allylcysteine have anticancer effects against prostate cancer cells in the laboratory. Garlic is a versatile herb that can be easily added to food.
6. Mushrooms
There are a variety of different fungi with different chemical constituents. Shiitake mushrooms, reishi, Coriolus versicolor, and maitake are known to have cancer-fighting properties. The ability of anti-cancer effect is thought to contain polysaccharides which boost the immune system so strong against cancer.
Mushrooms also contain protein or sugar molecules called lectins. Lectins proven ability to prevent cancer cells proliferate. Other compounds in fungi is ergosterol peroxide which can inhibit the growth of prostate cancer cells, according to a study published in the journal Biological Interactions chemico.
In a study in Korea, the scientists found that the fungus yamabushitake potential against leukemia in humans. The use of shiitake extracts in cancer patients also showed promising results. The researchers found that patients gastrointestinal cancer or breast cancer who took the mushroom extract along with chemotherapy experienced improved quality of life and immune function.
7. Raspberries
Raspberries are a source of antioxidants and phytonutrients called anthocyanins that may protect the body from cancer. In a study published in the journal Cancer Research, the mice were given food containing 5% - 10% black raspberries decreased number of esophageal tumors by 43% - 62%.
In subsequent studies, extracts of black raspberries inhibited colon cancer cell growth, and esophageal cancer in rats. In a study by Ohio State University, a black raspberry powder administered to patients suffering from colorectal cancer. The researchers found evidence that black raspberries have a positive impact on the reduction of colorectal cancer.
8. Grape
Resveratrol is an antioxidant that is usually contained in grapes and red grape. A study conducted by the U.S. Department of Agriculture found that resveratrol slowed the growth of prostate cancer cells.
A study from Italy confirmed the evidence that resveratrol and anti-inflammatory properties can help fight the deadly cancer. Researchers in Japan have also found that resveratrol makes colon cancer cells to commit suicide.
9. Tomatoes
Antioxidants and phytonutrients are concentrated disebit lycopene in tomatoes are cooked or processed. A large study involving almost 48,000 men found that men who consume tomatoes and tomato products have a 35% lower risk of prostate cancer and 53% lower risk of aggressive prostate cancer.
The researchers confirmed that consumption of tomato products are associated with reduced risk of prostate cancer. In addition, several studies have shown that consumption of tomatoes and lycopene is associated with decreased risk of lung cancer.
10. Turmeric
Turmeric has been regarded as anti-cancer food because it has a variety of important anti-cancer properties. In the journal Frontiers of Bioscience, researchers found that curcumin, the active ingredient in turmeric, has various anti-cancer properties.
Numerous studies have shown that curcumin is very strong against colon cancer. The study, published in the journal Nutrition and Cancer showed that curcumin is used in conjunction with chemotherapy is an effective strategy to treat gastrointestinal cancers.
