A widely-held misconception suggests that sugar directly contributes to cancer development, but the truth is more nuanced. According to registered dietitian Paige Welsh of the Cleveland Clinic, our bodies need a specific type of sugar called glucose to function properly.
While all cells, including cancer cells, require energy in the form of sugar, there is no direct link between consuming sugar and developing cancer. Instead, added sugars found in processed foods are a concern, as they can contribute to obesity and other health issues linked to cancer.
Welsh recommends limiting daily added sugars to 25 grams for females and 36 grams for males. For overall diets, focusing on whole foods with naturally occurring sugars, such as fruit, is recommended. Moderation is key when indulging in treats like chocolate or ice cream. By being mindful of sugar intake, individuals can reduce their cancer risk while maintaining a balanced diet.
