Sugar-free foods are products that do not contain added sugars. These foods often use alternative sweeteners, such as stevia, aspartame, or erythritol, to provide sweetness without the calories associated with sugar. They are popular among individuals looking to reduce their sugar intake, manage weight, or control blood sugar levels. Many sugar-free options are available, including snacks, beverages, and desserts. However, it's important to read labels carefully, as some sugar-free foods may still contain carbohydrates or other ingredients that can affect health. Always consult with a healthcare professional when making significant dietary changes.
