True or False: Agave's the Healthiest Sweetener Out There 

Could it be true? Is there really an all-natural, low-calorie sweetener—with no aftertaste—that doesn't send your blood sugar into the stratosphere? Fans say agave (ah-GAH-vay) nectar fits that description. And to judge by the flood of agave-sweetened foods and drinks on supermarket shelves—hundreds have been introduced in the last 2 years—the new sweet stuff has a lot of believers. It's even showing up in cocktails at trendy bars. So, is it true? Or too good to be?

T or F: Agave is super sweet.
True indeed! It's four times sweeter than white sugar. Just 1/4 teaspoon of agave nectar/syrup approximates the sweetness of 1 teaspoon of sugar, costing you just 4 calories instead of 16.

T or F: Agave is all natural.
True, sort of. But "all natural" doesn't mean "not processed." Agave comes from the desert-dwelling succulent Agave tequilana, which is also the source of tequila. However, turning the plant's juicy sap into a syrupy nectar you can drizzle on yogurt or stir into tea takes some doing. Some manufacturers heat the sap; others use enzymes to convert it into table-ready syrup.

T or F: Agave has no flavor.
True and false. It depends on whether the syrup is light or dark. The lightest types are virtually flavorless, but darker varieties have a maple- or caramel-like taste that you may take to . . . or not.
