"Fat-free" refers to food products that contain little to no fat, typically less than 0.5 grams of fat per serving. These items are often marketed as healthier alternatives for those looking to reduce their fat intake, which can be beneficial for weight management and heart health. Common fat-free foods include yogurt, milk, and various snacks. However, it's important to note that fat-free does not always mean healthier. Some fat-free products may contain added sugars or artificial ingredients to enhance flavor, which can offset the benefits. Always check the nutrition label to understand what you're consuming, even in fat-free options.
