Almost all of breast cancer patients have to deal with food problems during treatment period. BCNV introduces a post from website www.foodforbreastcancer.com to answer the question: “If you have triple-negative breast cancer, which food will you choose to get the best result of treatment?”
Triple-negative breast cancer refers to the fact that the cancer is estrogen receptor negative (ER-), progesterone receptor negative (PR-), and HER2/neu negative. In other words, triple negative breast cancers do not express receptors for estrogen or progesterone and do not overexpress HER2.
Women diagnosed with triple negative breast cancer are more likely to be premenopausal than women with hormone receptor positive breast cancer. Treatments or foods that reduce the production of estrogen or block its effects in the body are not useful for this type of breast cancer.
Women with metabolic syndrome are more likely to have triple negative breast cancer upon diagnosis than women without it. A high cholesterol diet has been shown to induce angiogenesis and accelerate mammary tumor growth in a mouse model of triple negative breast cancer.
Foods that reduce the risk of triple negative or ER-/PR- breast cancer
The following foods and spices have been found to be associated with reduced risk of triple negative or ER-/PR- breast cancer:
Broccoli & broccoli sprouts
Flaxseed & flaxseed oil
Grapes, red or black
Grape juice, purple
Honey, min. processed
Olives and olive oil
Plums, purple or red
Reishi mushroom tea
Rice, brown, black or red
Sweet potatoes, purple
Walnuts & walnut oil
One study reported that breast cancer patients with suboptimal levels (under 32 ng/mL) of vitamin D were three times more likely to develop triple negative breast cancer than patients with optimal levels. In other words, low vitamin D appears to increase the aggressiveness of breast cancer that develops.
Foods and supplements that increase the risk of ER-/PR- breast cancer
The following foods have the potential to increase the risk of ER-/PR- breast cancer or its progression:
Apricots, dried, non-US — potential for high cadmium levels
Bacon and other processed meats
Beef and veal, especially liver
Copper supplements, including multivitamins
Indian mustard or black mustard
Lamb, especially lamb liver
Peanuts and peanut oil
Pork and lard
Rice from Louisiana, Thailand or India — potential for high cadmium levels
Highly salty foods
Products made from defatted soy flour, such as soy protein isolate & textured soy protein
Sunflower seeds and sunflower oil
Vitamin E supplements, alpha-tocopherol
Vitamin K supplements
Fructose has also been shown to induce changes in triple negative breast cancer cells that may increase their aggressiveness, suggesting that patients should avoid concentrated sources such as agave nectar and processed foods sweetened with fructose, including beverages.
Foods that can help reduce or regulate blood sugar and insulin levels
The foods below have been shown to help regulate glucose, increase insulin sensitivity and/or reduce circulating insulin levels while also protecting against breast cancer. Consuming such foods may help reduce the likelihood or extent of metabolic syndrome.
Olives & olive oil
Brown rice, U.S. grown
Walnuts & walnut oil
