Contrary to decades of popular belief (and anecdotal evidence from generations of parents), a new study has found that there is no such thing as a sugar rush. That’s right. The sugar rush is a myth. Rather than making people feel energized and hyped, the new research suggests eating sweet foods actually causes people to experience the opposite: fatigue and a lack of alertness.

The results — which were published in June in the journal Neuroscience and Biobehavioral Reviews — come from a meta-analysis of 31 published studies involving almost 1,300 people. A team of European researchers sought to understand the effect of sugar on people’s moods, including anger, alertness, depression, and fatigue. Overall, they wanted to know how does this carbohydrate impact both the way people feel in terms of pleasure, as well as cognitive ability and sharpness.

Surprisingly, they discovered that sugar consumption has virtually no effect on how people act and feel, regardless of how much sugar is consumed or whether people engage in demanding activities after consuming it. Meaning sugar doesn’t give us a jolt of energy or affect the way people think or process situations — it doesn’t even make people do better in sports, a common misconception, researchers say.

Ummm…as an observer, and a parent, I calls ’em like I sees ‘em.

And what I see here is that the basic theory underlying science in this area (and the practice of medicine) is inadequate both to explain the anecdotal observation of a “sugar rush” and…

Those guys don’t have kids at home!

Paraphrasing Han Solo:

“I thought it was a bunch of mumbo jumbo. A magical power holding together good and evil, the dark side and the light. The crazy thing is… it’s true. The Sugar-Rush, the hyperactivity. All of it. It’s all true.”
