Honey tastes sweeter than table sugar (sucrose).
This is because honey is composed mainly of fructose and glucose, and fructose is perceived as sweeter than sucrose. As a result, when using honey instead of sugar in cooking or baking, you can often achieve the same sweetness with a smaller amount.
Honey is also lower in calories by weight. Per 100 grams, honey contains about 294 kcal, compared with about 384 kcalfor table sugar.
Because honey provides greater perceived sweetness with a smaller amount, it can also help reduce your overall calorie and sugar intake when used as a substitute for sugar.
