Brand new, sealed bag! Purchased and then went on a diet, so I won't make use of this. Erythritol is 70% as sweet as table sugar, yet it is virtually non-caloric, does not affect blood sugar, and does not cause tooth decay. Under U.S. Food and Drug Administration (FDA) labeling requirements, it has a caloric value of 0.2 calories per gram. Diabetics will be happy to know that on the glycemic index, Erythritol is rated at zero.
