What are extrinsic sugars?

Extrinsic sugars refer to sugars that are added to food and beverages, typically during processing or preparation. This includes not only table sugar (sucrose) but also various sweeteners, such as high fructose corn syrup and honey, which are intentionally included to enhance flavor or preserve food. Understanding this classification is crucial for identifying how dietary habits can impact dental health, as these added sugars are often found in processed foods.

In contrast, natural sugars, such as those found in fruits and milk, are intrinsic sugars that occur naturally alongside vitamins, minerals, and other beneficial nutrients. Fiber-rich carbohydrates, as well as proteins from dairy, do not fall into the category of extrinsic sugars because they serve different nutritional functions in the diet. Recognizing the distinction between extrinsic and intrinsic sugars can help dental professionals guide patients on healthier dietary choices to minimize the risk of cavities and other dental issues.
