If you've ever had sugar cravings so bad that you sold scrap metal to make money for a box of Nerds, dude, what is wrong with you? For most people, itching for the next sugar fix, and the sense of euphoria you feel after indulging in your sweet of choice, seems strikingly similar to an addict scoring another high.
It's not your fault; there have been plenty of studies comparing sugar's effects on the brain to those of drugs. Plus, eating more sugar leads to more sugar cravings, creating a downward spiral like the kind that lands people in rehab.
As it turns out, the notion of a sugar addiction is a tad dramatic. Sure, it's a great tool for selling the latest diet book or promoting a new nutrition craze, but the scientific evidence of an actual dependency on sugar is limited, according to new findings. "We find little evidence to support sugar addiction in humans," the neuroscientists from the University of Cambridge wrote. Sorry, chocoholics.
Previous studies looked at rodents instead of humans
Welp, if you thought you needed a doctorate in neuroscience to point out some obvious logical flaws, you were off by a mile. The team of scientists came to their conclusion after reviewing previous studies on sugar addiction, and finding some red flags. A big one was that most of these studies looked at rodents instead of humans. Even if rats love pizza as much as people, the similarities in brain function aren't strong enough to base our responses to sugar on theirs. They're a good starting point, being mammals and all, but yeah: rats do not equal humans.
