Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. The most common risk factors for cancer include aging, tobacco, sun exposure, radiation exposure, chemicals, other substances, viruses and bacteria, certain hormones, family history of cancer, alcohol, poor diet, lack of physical activity, or being overweight.
A comprehensive review of thousands of studies on diet, physical activity, and weight conducted for the World Cancer Research Fund and the American Institute for Cancer Research pointed to the benefits of eating mostly foods of plant origin. Foods such as broccoli, berries, and garlic showed some of the strongest links to cancer prevention. These superfoods prevent cancer from the body:
1. Garlic
The same sulfur compounds causing garlic odour may also stop cancer-causing substances from forming in your body, speed DNA repair, and kill cancer cells. Garlic battles bacteria, including H. pylori (the one connected to some ulcers and stomach cancer), and research suggests it reduces the risk of developing stomach, colon, esophageal, pancreatic and breast cancer. The World Health Organization recommends that adults consume approximately one clove of garlic daily to promote good health.
2. Broccoli
Broccoli and its cousins are most protective against cancers of the prostate, lung, colon, breast, bladder, liver, neck, head, mouth, esophagus and stomach, according to a review of hundreds of clinical studies conducted for the World Cancer Research Fund and the American Institute for Cancer Research.
3. Tomatoes
The red coloring in tomatoes makes a juicy, ripe one hard to resist — and makes them a potential weapon against prostate cancer and heart disease. That red hue comes from a phytochemical called lycopene, a powerful antioxidant, which is most concentrated in tomatoes. Several studies suggest that a lycopene-rich diet is connected to a reduced risk of prostate cancer
4. Berries
Strawberries and raspberries are rich in antioxidants such as vitamin C and ellagic acid, a phytochemical. In laboratory tests, ellagic acid seems to have anticancer properties that rev up enzymes, which destroy cancer-causing substances and slows the growth of tumors. It seems to prevent cancers of the skin, bladder, lung, esophagus and breast. They also contain flavonoids, which suppress an enzyme that damages DNA and has been linked to lung cancer. Other types of berries, all rich in flavonoids, deserve a spot on your plate, too: blackberries, blueberries, and cranberries. Blueberries are packed with anthocyanins, which reduce inflammation and are one of the most powerful antioxidants.
5. Carrots
One of the easiest vegetables to love, carrots are packed with disease-fighting nutrients. They contain beta-carotene, an antioxidant scientists believe may protect cell membranes from toxin damage and slow the growth of cancer cells. And carrots deliver other vitamins and phytochemicals that might guard against cancers of the breast, mouth, pharynx, larynx, esophagus, and stomach.
6. Spinach
Spinach is rich in lutein and zeaxanthin, carotenoids that remove unstable molecules called free radicals from your body before they damage it. They’re found in spinach and other dark green leafy vegetables, and some studies show they could protect against cancer of the mouth, esophagus, and stomach. Some studies suggest the carotenoids in spinach and other foods reduce the risk of ovarian, endometrial, lung, and colorectal cancer.
