Nope. All sugar, whether it's brown, raw, honey, agave, coconut, or fruit juice concentrate, is a carbohydrate that contributes 4 calories per gram to your diet and little else besides sweet satisfaction.
Some people argue that sweeteners such as agave and honey are more natural and contain trace amounts of minerals. Truth is, those minerals won't do you any good unless you eat a tremendous quantity of sweetener—and that won't help at all.
Bottom line: Choose sugars for flavor.
