There are many myths surrounding the topic of sugar and cancer. It is often said that “sugar feeds cancer.” What are the facts based on current medical and dietary knowledge?
➡︎ Sugar as a source of energy
Every cell in the body, including cancer cells, uses glucose as an energy source. However, this does not mean that eliminating sugar will stop cancer growth – the body can also obtain glucose from proteins and fats.
➡︎ Insulin and cancer cell growth
Sugar consumption can raise insulin levels, which have been implicated in the growth of some cancers. However, sugar alone is not the only factor – overall diet quality and lifestyle play a key role.
➡︎ Does a low-carb diet inhibit the development of cancer?
Some studies suggest that a ketogenic diet (low-carb, high-fat) can support cancer treatment, but this has not been clearly confirmed, and what's more, such a diet can lead to numerous side effects and nutritional deficiencies, which is particularly disadvantageous for patients undergoing treatment, when the body should be properly nourished and strengthened.

➡︎ The importance of a healthy diet
Instead of eliminating sugar completely, it is worth opting for a balanced diet based on whole grains, vegetables, fruits, legumes and healthy fats. Excessive amounts of simple sugars, especially in the form of processed products, can promote inflammation and obesity, which increase the risk of cancer.
Summary – Should You Avoid Sugar Completely?
There is no evidence that sugar directly “feeds cancer,” but too much sugar in the diet can influence factors that contribute to cancer development. A balanced diet and an active lifestyle are key to maintaining a healthy metabolism and supporting the body in the healing process when disease does occur.
In summary, it is not necessary to completely avoid sugar, but it is worth limiting its consumption and choosing healthy sources of carbohydrates, such as whole grains, vegetables and fruits, which additionally provide the body with a number of vitamins, microelements and dietary fiber.
