Sugar is found in many processed foods. It is being studied as to its risk of causing cancer. Some people avoid eating sugar because they believe it can cause cancer.
One article (1) looked into the risk of developing cancer when one eats a lot of sugar. It noted that avoiding sugar altogether can increase stress, which raises blood sugar even if a person doesn’t eat a lot of sugar in their diet.
The article indicated that eating a lot of sugar can cause insulin resistance, which can ultimately lead to diabetes. Diabetes is sometimes associated with an elevated risk of developing cancer. It also indicated that the relationship between diabetes and cancer has not been well established. It means that it is not yet clear whether a diet high in sugar can cause cancer.
