Blueberries Kill Breast Cancer Stem Cells, Halt Growth by 95% : This is a major discovery and further supports that #blueberries are a super-food against breast cancer. Pterostilbene, found in blueberries and grapes, has now been shown to markedly suppress breast cancer stem cells for both ER+ (MCF-7) and ER- (MDA-MB-231) breast cancers. This is important because cancer stem cells are highly resistant to normal therapies like radiation or chemo, are virtually immortal, and continue to generate more #cancer cells the longer they live. This new study also showed that pterostilbene improved the infiltration of immune cells into the tumor and reduced the cancers ability to spread (metastasize). In another recent study, pterostilbene potently suppressed the growth of MCF7 breast cancer cells by up to 95% in vitro. Does this translate into a real benefit for women? Yes. A recent landmark study on over 75,000 nurses in the USA (Nurses Health Study Cohort) found that postmenopausal women eating at least one serving of blueberries weekly had a stunning 31% reduction in ER- breast cancer risk. Note that one serving = 80 grams or 3 ounces, which is just over half a cup of fresh blueberries. ncbi.nlm.nih.gov/pubmed/23504987 #breastcancer #stemcell #pterostilbene
