Each cell in our body, including any cancer cells, uses sugar (glucose) from our blood to fuel its metabolism. The foods we eat, even the healthful vegetables, fruits, and whole grains, provide this source of energy. There is no clear evidence that dietary sugar preferentially feeds tumors over other cells in the body. The connection is an indirect one: eating lots of high-sugar foods increases the risk of obesity, and in turn increases the risk of many cancers. Learn more in this video.
