Why do we crave sugar even when we are not hungry?

In this Science for Sleep journey, we explore the biology behind sweetness, from the receptors on your tongue and the glucose-sensing cells in your gut to dopamine, learned food preferences, chocolate, artificial sweeteners, and why dessert can still sound appealing after a full meal.

We will also trace sugar through human history, from wild fruit and honey to sugarcane, crystallized sugar, plantations, beet sugar, and modern food production, revealing how an ancient attraction to sweetness became part of everyday life.
