Does sugar really feed cancer cells?

With all the information on the internet, especially with regards to diet, you have made the decision to eliminate all unhealthy foods responsible for the development of cancer or its progression, starting with sugar. But does sugar really feed cancer cells? Read the following to find out.

As the number one enemy of cancer according to some sites, sugar is frequently accused of feeding your cancer cells. So would restrictive sugar-free diets be the answer?

First of all, it might be important to understand where does the myth that sugar (or glucose) fuels cancer come from. If the logic is that cancer cells need a lot of sugar to progress, eliminating it from your diet should help stop the growth of cancer, and could even prevent it from developing in the first place. Unfortunately, it is not that simple.

You see, all healthy cells also need sugar to function well. And there is no way (at the moment) to specifically deprive cancer cells of sugar without also harming healthy cells. You cannot tell your body to let healthy cells have the sugar they need and make sure they don't supply it to cancer cells.

Even when carbohydrates or sugar are not available because of your diet, your body will make it from other sources, such as protein or fat, to ensure the proper functioning of your body and brain. So removing sugar from your diet is not only difficult, it is almost impossible.

What the research says

According to the World Cancer Research Fund, the idea that sugar or artificial sweeteners are responsible for the development or growth of cancer is an oversimplification of complicated biology. There is no strong evidence to directly link sugar or artificial sweeteners to cancer risk. However, foods that are high in added sugar also tend to be high in calories, and sometimes fat, without being nutritious or filling. Eating high-calorie foods too often or in large quantities can lead to weight gain, and there is strong evidence that being overweight or obese increases the risk of many cancers.

Same story with the Canadian Cancer Society, Cancer Research UK, Mayo Clinic and Oncology Nutrition: Eating sugary foods does not make cancer cells grow faster. Likewise, depriving them of sugar does not make them grow slower. And there is also no strong evidence that eating a very low carbohydrate diet reduces your risk of cancer, helps you as a "natural treatment", or increases your chances of survival if you have received a diagnosis of prostate cancer. People consume thousands of food components daily, which is why it is difficult to establish precisely how diet is associated with cancer.

Nonetheless, there is some evidence that consuming large amounts of sugar is associated with an increased risk of certain cancers, including esophageal cancer. As mentioned above, eating too much sugar can also lead to weight gain and increase the risk of obesity and diabetes, which may increase the risk of cancer.

As healthy weight varies from person to person, to find out what yours is, ask your doctor for advice.

What you must remember

Blaming sugar as lethal gas or cancer enemy #1 is unrealistic. Preventing cancer begins with your lifestyle, such as leading a physically active lifestyle, adopting good eating and drinking habits - e.g. avoiding sugary drinks, and eating a healthy balanced diet that is rich in nutritious and filling foods, such as whole grains, fruit, vegetables, low-fat proteins -, not to mention maintaining a healthy weight and not smoking. Easier said than done you might say? Hence our favorite expression One bite at a time!
