Garlic is rich in sulfur compounds which strengthens our body's defense against the development of cancer. It is also known to reduce the growth of tumors.
One of the best kinds of food for cancer prevention is broccoli. However, steaming broccoli instead of heating it through the microwave is recommended since the latter can destroy almost all of the vegetable's cancer-preventive flavonoids. Population studies first pointed to the role that broccoli and other cruciferous vegetables might play in cancer prevention. One 10-year study of 47,909 men, published by the Harvard School of Public Health, showed an inverse relationship between the consumption of cruciferous vegetables and the development of bladder cancer.
The reason why Brazil nuts are great food for cancer prevention is because of its selenium content. "A Harvard study of more than 1,000 men with prostate cancer found those with the highest blood levels of selenium were 48 percent less likely to develop advanced disease over 13 years than men with the lowest levels," Reader's Digest shares.
Taking fish-oil supplements for at least 10 years can shrink your risk of ductal carcinoma, the most common type of breast cancer, according to a study in Cancer Epidemiology, Biomarkers & Prevention. It’s thought that the omega-3 fats in fish oil reduce inflammation, which may contribute to breast cancer. But you can skip the supplement aisle, say the study’s researchers, and eat about 8 ounces of oily fish (salmon, sardines, tuna) a week.
Citrus fruits such as lemon, lime, oranges, grapefruit, pomelo and tangerine are also known to help the body in cancer prevention. According to a study conducted by Australian researchers, the risk for cancers of the mouth, throat and stomach is reduced by approximately 50 percent by eating citrus fruits every day.
Citrus fruits are most protective against stomach, mouth, larynx and pharynx cancers. Some studies also show benefits for heart disease and stroke, as well as a myriad of other conditions ranging from arthritis to Alzheimer’s disease, cataracts and gallstones.
