Breast Cancer and Multivitamins

At the end of March the American Journal of Clinical Nutrition published a study conducted by the Karolinska Institute of Sweden involving 35 000 people linking multivitamin use with a nineteen per cent increased risk of breast cancer. This research has found its way into the mainstream Australian media and so deserves comment. The journal and institution involved do fine work but this study has its limitations. As the Complementary Healthcare Council of Australia pointed out, no detailed analysis of the multivitamins used was undertaken. Hence they could have been very low dosage and poorly manufactured: we just don’t know. Additionally, what of one study published in February 2009 involving more than 160 000 and another involving almost 3000 people published in December 2009 finding no link between multivitamin use and breast cancer incidence? Memo to media outlets: when reporting health studies, put them in context.Meanwhile if you visit Meijer Ad that contains mostly likewise discounts with Winn Dixie Ad you surely have a range like ALDI Ad.
