One of the most health-promoting properties of agave nectar is its favorable glycemic profile. Its sweetness comes primarily from a complex form of fructose called inulin. Fructose is the sugar that occurs naturally in fruits and vegetables. The carbohydrate in agave nectar has a low glycemic index, which provides sweetness without the unpleasant "sugar rush" and unhealthful blood sugar spike caused by many other sugars. Agave nectar is a delicious natural sweetener that can be used moderately - by dieters, some diabetics, and health conscious cooks - to replace high-glycemic and refined sugars. Agave Nectar has been used for centuries as a flavoring, though native populations have also been aware of its health benefits and used it medicinally. The Aztecs used a mixture of agave nectar and salt as a dressing for wounds and a balm for skin infections.
