Can dark chocolate prevent cancer?

As a subject matter expert in nutrition and health, I'd like to clarify that while certain components of dark chocolate have been studied for their potential health benefits, it is not accurate to say that dark chocolate can prevent cancer. Dark chocolate does contain flavanols, which are a type of antioxidant that has been associated with a variety of health benefits, including potentially reducing the risk of certain diseases. However, the relationship between flavanols and cancer prevention is complex and not fully understood. Some studies suggest that flavanols might have anti-cancer properties, but these findings are preliminary and more research is needed to establish a definitive link. It's important to note that dark chocolate also contains cocoa butter, which is high in saturated fats. While moderate consumption of dark chocolate can be part of a healthy diet, excessive consumption due to its high-fat content can lead to increased cholesterol levels and potentially raise the risk of heart disease. In summary, while dark chocolate may have some healthful properties, it is not a cancer prevention tool, and it should be consumed in moderation as part of a balanced diet.

Cancer–Fighting Cocoa. ... For example, dark chocolate contains powerful cancer-fighting antioxidants called flavanols, but also includes cocoa butter which has high levels of unhealthy saturated fat that can raise cholesterol levels and increase your risk of heart disease when consumed in excess.
