Cocaine more addictive than first thought, study finds

And added sugar is even more addicted than cocaine. Added sugar is what you want to watch out for. Natural sugars found in fruits such as apples or bananas have such high fiber content that the insulin spike in blood is blunted tremendously as compared to an insulin spike you would have eating a food containing added sugar: "When you look at animal studies comparing sugar to cocaine," DiNicolantonio told Here & Now's Lisa Mullins, "even when you get the rats hooked on IV cocaine, once you introduce sugar, almost all of them switch to the sugar."

Overall, this research has revealed that sugar and sweet reward can not only substitute to addictive drugs, like cocaine, but can even be more rewarding and attractive. At the neurobiological level, the neural substrates of sugar and sweet reward appear to be more robust than those of cocaine (i.e., more resistant to functional failures), possibly reflecting past selective evolutionary pressures for seeking and taking foods high in sugar and calories.
