Agave syrup is a sweetener derived from the sap of the agave plant, which is native to Mexico. It is often used as a natural alternative to sugar and is known for its low glycemic index, meaning it may have a lesser impact on blood sugar levels compared to traditional sweeteners. The syrup is produced by extracting the sap from the agave plant, then filtering and heating it to break down the carbohydrates into sugars. It has a mild flavor and is commonly used in beverages, desserts, and as a topping for various foods.
