Sweet poison: why sugar is ruining our health

The average Briton consumes 238 teaspoons of sugar each week - often without knowing it. But just how hard is it to go sugar free?


This article was first published on April 12, 2013 and has been republished as Action on Sugar calls for a ban on the sale of sugary energy drinks to children. The charity says they are "fuelling the obesity epidemic."
 
Like it or lump it, few of us get through the day without adding sugar to our daily diet. We are a Pavlovian population made up of sugar, treacle and toffee addicts, drawn to the taste of sweetness like bees to honey. So ingrained is our desire that even writing about sugar now is sending my salivary glands into overdrive as my brain reacts to the very thought of it, whizzing neurotransmitters around to prepare my body for some serious glucose action. Perhaps you, while reading this, are reaching – almost unwittingly – for a chocolate Hobnob?
But that’s not a problem, is it? We could stop and eat a piece of cheese instead – any time we wanted. Or could we?
Maybe not. It seems that our desire to load up with sugar regularly may not be the cheeky reward-cum-energy boost we think it is. Increasingly, experts believe we can be truly addicted to sugar. French scientists in Bordeaux reported that in animal trials, rats chose sugar over cocaine (even when they were addicted to cocaine), and speculated that no mammals’ sweet receptors are naturally adapted to the high concentrations of sweet tastes on offer in modern times. They worried, in a paper published in 2007, that the intense stimulation of these receptors by our typical 21st-century sugar-rich diets must generate a supra-normal reward signal in the brain, with the potential to override self-control mechanisms and thus to lead to addiction.
So if you feel like you are craving a chocolatey treat, that craving is more than just a figure of speech. You may be one of the world’s most common dependants: a sugar addict.
