Tagatose

"Tagatose is a rare, low-calorie sugar substitute that tastes similar to sucrose but has fewer calories and a minimal impact on blood sugar, making it suitable for keto and diabetic diets. Found naturally in small amounts in dairy and some fruits, it's typically manufactured for use in a wide range of foods like beverages, baked goods, and frozen desserts, offering sweetness, texture, and prebiotic benefits."
