I am not sure that there is a reliable (ie scientifically credible) about the benefits of a sugar free diet, assuming you could achieve that, as distinct from a low sugar diet, which is more achievable. Glucose (the form of sugar used most in the body) feeds every cell in the body, and is so important to the function of your brain that the body has several back up strategies to keep blood sugar levels normal. Even without any carbohydrate in the diet, your body will make sugar from other sources, including protein and fat. The notion that sugar ‘feeds’ cancer cells is nowhere near as clear as it sounds! There is some support for limited fasting, which in combination with a good, balanced diet (vegetables, fibre protein) may be the best bet for any of us in keeping healthy. Remember too that, if you are having chemo, your taste buds can be affected, another challenge for healthy eating, but at least a finite one. Best wishes
