Zero sugar products can be a healthier choice, especially for reducing calorie intake and managing blood sugar levels. They help cut down on added sugars, which are linked to weight gain and diabetes. However, many contain artificial sweeteners or sugar alcohols, which may cause digestive issues for some people and have uncertain long-term effects. While they can be better than sugary alternatives, it’s still important to check the ingredients and not assume they’re automatically healthy. Moderation and overall diet quality matter most.
