Sugar as an addiction like any other, but more popular.
A drug that can intoxicate, infuse us with energy and can be taken by mouth. It doesn’t have to be injected, smoked, or snorted for us to experience its sublime and soothing effects. It mixes well with virtually every food and particularly liquids, and that when given to infants it provokes a feeling of pleasure so profound and intense that its pursuit becomes a driving force throughout their lives… There is something about the experience of consuming sugar and sweets, particularly during childhood, that readily invokes the comparison to a drug. Most of us today will never know if we suffer even subtle withdrawal symptoms from sugar, because we’ll never go long enough without it to find out.
Addiction researchers have come to believe that behaviours required for the survival of a species – specifically, eating and sex – are experienced as pleasurable in this part of the brain, and so we do them again and again. Sugar stimulates the release of the same neurotransmitters.
