Question

Why most animals ,insects &humans prefer to eat sugar than anything else ?

Answer 1

Our cells break down glucose for energy, they need to to keep living. Pure sugar is basically glucose, and a very simple form of it. We can get glucose from almost any food, but sugar is very quick and easy to digest.

Pure sugar is naturally very rare though and before humans started producing sugary foods we would very rarely have eaten it. But as an excellent and easy source of energy sugar is a good thing to eat, so we've evolved to be attracted to sugary foods and eat then when they're available in preference to other less sugary foods.

Answer 2

The chemical energy your body needs comes from glucose, a simple sugar molecule. Consuming table sugar (sucrose, which is easily converted to glucose) hence provides your body with a quick source of energy.

Answer 3

Sugar is sweet for all animals.
