Blueberries rank among the highest of all fruits and vegetables in the capacity to destroy free radicals.
Breast cancer-related effects of eating blueberries
Blueberries have been found to inhibit mammary cancer cell proliferation in rats, as well as inhibiting cultured cancer cell growth in the laboratory and blood vessel tumors in rats. Blueberries contain ankaempferol, caffeic acid, catechin, chlorogenic acid, epicatechin, ferulic acid, gallic acid, kaempferol, myricetin, naringenin, p-coumaric acid, p-hydroxybenzoic acid, pterostilbene, resveratrol, and quercetin, most of which have been reported to have anti-cancer properties.
Blueberries are a good source of resveratrol, which has been shown to increase the effects of radiation, aromatase inhibitors and the chemotherapy drug Taxol (paclitaxel) against breast cancer.Additional comments
The antioxidant properties of blueberries have been shown to be reduced when eaten with milk, suggesting that the best way to gain maximum benefits from blueberries and other fruits eaten for their polyphenol content is to consume them either one hour before or two hours after protein is consumed.
Buckwheat is recommended for breast cancer
Buckwheat (Fagopyrum esculentum Moench) is rich in phytochemicals, including rutin, isoquercitrin, quercetin, catechin, myricetin and various anthocyanins. Buckwheat is also a dietary source of vitamin E, zinc, copper, selenium, and manganese. Components of buckwheat have been found to have antioxidant, anticarcinogenic, antimutagenic, and antifungal properties. Consumption of buckwheat has been shown to reduce gut transit time compared to consumption of white rice, resulting in lower levels of triglycerides, total cholesterol and LDL cholesterol. Consuming buckwheat may also reduce gallstone formation, reduce colon inflammation and contribute to blood sugar control. One animal study found that germinated buckwheat had potent anti-fatty liver activities. A component of buckwheat has been shown to reduce proliferation of multiple myeloma cells. Rutin, a major active component of buckwheat, has been found to have anti-angiogenic activity against melanoma in mice, reducing the number of tumor-directed capillaries formed. Rutin also was found to inhibit the proliferation, migration and capillary-like tube formation of human endothelial cells.
Breast cancer-related effects of eating buckwheat An extract of buckwheat hulls has been shown to have cytotoxic effects in human breast, liver and stomach cancer cells. A peptide of buckwheat seeds has been found to inhibit proliferation of liver and breast cancer cells, as well as leukemia cells. A component of tartary buckwheat (similar to buckwheat) has been found to have antiproliferative effects in human breast cancer cells. Buckwheat also has been shown to inhibit carcinogen-induced mammary tumors in laboratory rats by lowering circulating estrogen.
Additional comments
Buckwheat honey has been found to be a better source of antioxidants than lighter-colored honeys. Japanese soba noodles are made from buckwheat flour. Tartary buckwheat (Fagopyrum tataricum Gaertn.) is a type of buckwheat regularly consumed in China and parts of India. It has a phytochemical profile similar to common buckwheat, with somewhat more rutin and quercetin.
