evidence: The relationship between sugar and cancer has been the subject of public debate for decades. If you or a loved one are facing cancer, it’s likely a question you’ve considered as well. The truth is blood sugar, also known as glucose, feeds all your cells, including cancer cells. "Because many healthy foods with cancer-fighting and immune-boosting nutrients contain sugar, cutting out all sources of sugar isn’t the best solution. Luckily, there is a lot you can do with your diet and lifestyle to prevent cancer and support treatment, says Lynne Groeger, M.S., R.D., C.S.O., Registered Dietitian specializing in oncology nutrition with Riverside Cancer Care Center. [...] Our body is designed to use blood sugar as fuel, so while sugar does feed cancer cells it also feeds healthy cells. Oversimplifying the sugar and cancer debate can cause more harm than good, creating stress and anxiety around food and mealtime. Focus on overall lifestyle changes, rather than worrying about one food, to benefit your health.
