The American Institute on Cancer Research (AICR) found evidence that foods containing whole grains can decrease one’s risk of developing colorectal cancer. Whole grains are rich in fiber, vitamins, minerals and plant compounds (phytochemicals) that protect cells from the types of damage that may lead to cancer. Whole-grain foods include breads, rolls, pasta and cereals; whole grain oat cereals such as oatmeal, popcorn, wild rice, tortilla and tortilla chips, corn, kasha (roasted buckwheat) and tabouleh (bulghur wheat).
Note -soy consumption is not recommended for women with estrogen-receptive breast cancer or who are taking anti-estrogen medications such as tamoxifen or aromatase inhibitors. Researchers suggest that these patients avoid soy until more is known.
Note: Very high amounts of green tea components (usually associated with overdosage of green tea supplements) have been shown to interact with drugs that affect blood clotting such as aspirin. Be careful!
Caution: High amounts of flaxseed and flaxseed oil can reduce blood clotting and promote bleeding, and may interact with drugs that that have a similar effect, such as aspirin.
Researchers at UCLA say cranberries contain tumor-blocking compounds, including phenolicacids, glycosides, and anthocyanins. These compounds are effective at preventing cancer in the colon and prostate as well as on the head and neck. They either kill the cancer cells or slow down their growth. Every day, have some cranberry juice, cranberry sauce or dried cranberry snacks.
