Some researchers in Belgium just did an interesting study about how yeast cells use sugar. This study helps to explain why yeast cells multiply rapidly when they have plenty of sugar. The results of their study could also explain why some cancer cells also multiply rapidly. However, this study does not mean that sugars and starches in the diet are a problem. In fact, high-carbohydrate diets actually help to protect against many cancers. Rather, the study explains why cancer cells with abnormal sugar metabolism might behave like yeast cells.
Many Cancer Cells Have an Abnormal Metabolism
Since the 1920s, scientists have known that many cancer cells don’t use oxygen to burn sugar, even when plenty of oxygen is available. By the 1950s, it was clear that tumors that are most likely to use anaerobic (no-oxygen) metabolism tend to be the most aggressive. Unfortunately, the reporters who have been covering this study for the popular press do not understand what the study is about or what its results really mean.
Many of the reporters have falsely concluded that the study shows that something in sugar is somehow causing cancer. As a result, they are urging people to avoid eating carbohydrates. But if people follow that advice, they would actually increase their risk of early death. If people avoid carbohydrates, they will end up eating more fat and more animal protein. High-fat diets increase your risk of heart attacks. Also, diets that are high in animal protein increase your risk of dying of cancer.
