Blueberries are highly recommended for breast cancer
Blueberries rank among the highest of all fruits and vegetables in the capacity to destroy free radicals. Blueberries contain caffeic acid, catechin, chlorogenic acid, epicatechin, ferulic acid, gallic acid, kaempferol, myricetin, naringenin, p-coumaric acid, p-hydroxybenzoic acid, pterostilbene, resveratrol, quercetin, and ursolic acid, most of which have been reported to have anti-cancer properties.
Breast cancer-related effects of eating blueberries
Blueberries have been found to inhibit mammary cancer cell proliferation in mice and rats, as well as inhibiting cultured cancer cell growth in the laboratory and blood vessel tumors in rats. Pterostilbene has been shown to inhibit obesity-related breast cancer growth and proliferation in the laboratory and to have additive treatment effects when combined with tamoxifen in estrogen receptor positive (ER+) breast cancer cells. Pterostilbene also has been shown to reduce the formation of breast cancer stem cells and inhibit their metastatic activities.
Blueberry extract has been shown to exhibit antitumor activity against MDA-MB-231 triple negative breast cancer cells and reduce their metastatic potential. Blueberry was found to inhibit cell proliferation in triple negative cells with no effect on normal breast cells in one study. Blueberry also reduced the metastatic potential of triple negative cells through inhibition of cell motility.
In animal studies, dietary blueberry has been shown to reduce triple negative tumor volume in female mice. Blueberry diets reduced triple negative proliferation (as measured by Ki-67) and increased cell death. In addition, a blueberry diet inhibited triple negative tumor metastasis in another mouse study. Analysis of tumor tissues has demonstrated that blueberry-fed mice tumors have significantly altered expression of genes important to inflammation, cancer, and metastasis.
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.
Non-organic blueberries must be washed very thoroughly to remove pesticide residue as much as possible.
Bilberries, which grow wild in much of northern Europe, are closely related to blueberries. They are valued for their high flavonoid content.
