Stevia, a plant-derived zero-calorie sweetener, is significantly sweeter than sugar and does not raise blood glucose levels, making it ideal for weight management and diabetic diets. It offers benefits for cardiovascular and oral health and can aid in calorie reduction for obesity prevention. While it may have a slight aftertaste and potential digestive effects if consumed excessively, stevia is widely regarded as a healthier sugar substitute. Using quality stevia in moderation can provide natural sweetness without the harms of sugar.
