Lead tastes good too, taste is not equivalent to importance.

  But it remains true that 1. Sugars are extremely important to your basic biological functioning. 2. Their extreme importance is the reason they taste good.

    Many people get by on diets with very little sugar. In the past when calories were harder to come by, the sweetness made sense as it indicated calorie-dense food. The sweetness is a proxy for calories. It would be more accurate to say that calories are extremely important. You can get calories from a variety of sources (starches, fats, and protein), however, not just sugar.of calories

      You get calories from starches by metabolizing them into sugar.

        There are plenty of people who eat low-carb diets. Glycolysis isn't the only metabolic pathway to produce energy. Your argument seems based on the macronutrient, not its metabolites, particularly as you're focussing on the taste. If the taste were driven by the metabolites, starches would taste sweet as sugar. Sugar (and carbs) aren't intrinsically crucial as a macronutrient. They're calorically dense, which is important when calories are scarce. When calories are plentiful, their importance wanes.
