Description and Uses
Rebaudioside A is a natural non-caloric sweetener. It is one of the predominant steviol glycosides isolated from S. rebaudiana leaves. It increases glucagon-like peptide 1 (GLP-1) secretion in a 2-dimensional mouse intestine model. In a two bottle preference test, mice drink more water containing rebaudioside A than unsweetened water, though saccharin-sweetened water is still preferred. Rebaudioside A is metabolized by gut microbiota to steviol , a compound whose safety is widely studied. Consumption of rebaudioside A formulations by pre-diabetic patients did not increase fasting or 2 hour plasma glucose levels or insulin levels.
Rebaudioside A is a glycoside from the stevia plant. Rebaudioside A is used as a sweetener with sweetness about 300 times that of sugar with negligible effect on blood glucose. As a result, Rebaudiosi de A is known for its application in treatment of many diseases like diabetes, high blood pressure and weight loss in some places. It is used as a food additive and in dietary supplements.
