The unique combination of antioxidant, anti-inflammatory, and pro-detoxification components in broccoli make it a unique food in terms of cancer prevention. Connections between cancer development and oxidative stress, chronic inflammation, and inadequate detoxification are so well-documented in the research that any food improving all three of these metabolic problems would be highly likely to lower our risk of cancer. In the case of broccoli, the research is strongest in showing decreased risk of prostate cancer, colon cancer, breast cancer, bladder cancer, and ovarian cancer. We expect that risk of other cancer types will also eventually be shown to undergo reduction from regular consumption of broccoli.
Blueberries are a very tasty way to help ward off cancer. The antioxidants in blueberries called anthocyanins have been shown to prevent cancer and specifically to reduce colon cancer risk. Several studies have demonstrated that blueberries decrease the risk of metastases which is a cancer spreading from its original site. Blueberries are low on the glycemic index so they usually do not affect sugar levels like other fruits can. Eating a cup of wild blueberries a day can help to prevent cancer.
If you’re looking to stack your odds against cancer, then eat plenty of tomato products. The healthy habit of eating tomato products has been linked with reduced risks of several types of cancers. The anti-cancer properties in tomatoes seem to be related to their antioxidant levels, particularly from their lycopene, beta-carotene, vitamin C, and phenols. Yet, research reveals that it’s all about the synergistic effects of lycopene and other nutrients in the tomato working together to offer cancer protection.
Rich source of cancer-fighting compound called allium, garlic and its relatives (onion, leeks, scallions, and chives) are shown to slow tumour growth and prevent breast cancer risk among other forms of cancer such as colorectal and prostate cancers. Garlic and onions are found in a variety of foods including Italian, Spanish, Indian, Thai and Chinese dishes. Crush or swallow a piece of garlic every morning and that’s all it takes to live a cancer-free life!
Nuts contain the antioxidants quercetin and kaempferol that may suppress the growth of cancers. Brazil nut contains 80 micrograms of selenium, which is important for those with prostate cancer. (Note: Many people are allergic to the proteins in nuts, so if you have any symptoms such as itchy mouth, tight throat, wheezing, etc. after eating nuts, stop. Consider taking a selenium supplement instead or work with someone on how to eliminate this allergy.)
