Grapes are highly recommended for breast cancer

Grapes contain polyphenols (resveratrol, quercetin, and catechin) that can act as antioxidants, antiangiogenics, and selective estrogen receptor modifiers. Each of these polyphenols have been found to have chemopreventative properties. Grapes also contain lupeol, pterostilbene, and fisetin, which also have been shown to have anti-cancer properties. Green or white grapes have less powerful anticancer properties than red grapes since they contain fewer polyphenols. Note that grape seed oil and grape seed extract are covered in another web page.

Breast cancer-related effects of eating grapes

Red grapes and grape seeds are a good source of resveratrol, which has the ability to suppress proliferation of breast cancer cells and promote cell death. Resveratrol also can inhibit aromatase (the synthesis of estrogen from androgens within the body), which is important for reducing growth-stimulatory effects in estrogen-dependent breast cancer. Other grape polyphenols such as quercetin and catechin have also been shown to have chemopreventive effects and appear to act synergistically with resveratrol in inhibiting breast cancer growth. Several population studies have reported that grape consumption is associated with reduced risk of breast cancer.

Resveratrol has also been shown to increase the effects of radiation treatment and the chemotherapy drug Taxol (paclitaxel) against breast cancer.

Additional comments

Non-organic (especially imported) grapes must be washed very thoroughly to remove pesticide residue.
