There are many, many differences between honey and sugar.
For example, while sugar is composed of fructose and glucose in equal measure, honey is composed +20 different types of sugars, trace elements, some vitamins and small amounts of minerals.
Then, while sugar is fast absorbed by the body (storing undigested calories for later use), honey’s digestion rate is much slower, therefore burning calories during digestion instead of storing them.
And, although honey is sweeter than sugar… it actual has a lower glycemic index. (This is NOT an excuse to overdo it, eh?)
