<strong>BY LEANNE MCCRATE, RD, LD, CNSC\r\n\r\nDear Dietitian,<\/strong>\r\nMy best friend was just diagnosed with breast cancer. She has been told that sugar\r\nfeeds cancer and that she should completely avoid all sweets. Is this true?\r\n<em><strong>Signed,<\/strong><\/em>\r\n<em><strong>Best Friend<\/strong><\/em>\r\n\r\n<strong>Dear Best Friend,<\/strong>\r\nWhen I ask people what they think about when they hear the word sugar, they inevitably\r\nreply white sugar. Our bodies break down all carbohydrates (starches, fruit, and white sugar) into glucose so that it can enter the cells and be used as energy. So yes, sugar feeds cancer cells as well as all the other cells in your body. The question is does sugar make cancer worse? The answer is no, there is no credible evidence to support this statement.\r\n\r\nThe link between sugar and any chronic disease, such as heart disease, diabetes, cancer, etc, is that excessive amounts cause weight gain, which in turn increases your risk of certain diseases.\r\n\r\nFurthermore, almost all patients undergoing chemotherapy will lose weight, which can result in malnutrition. These patients are advised to eat whatever they can. In a perfect world, everyone would eat the right amounts of protein and complex carbohydrates, fruits, and vegetables, but sometimes this just isn\u2019t possible. So if a cancer patient finds ice cream more palatable than boneless, skinless chicken breast, so be it.
