Moderation is important in this case. Yet avoiding food with high sugar content is definitely easier said than done these days, given the variety of options in stores. Some of the usual suspects include energy drinks, sodas, candy bars, artificial sweeteners, and so much more. Everyone has access to them.
What Lies Behind Sugar Addiction
Sugar addiction obviously begins when you crave anything that contains this sweet ingredient. Eating sugar triggers production of natural opioids in your brain. These hormones aid in relieving the pain and are triggered in the same way one would consume illegal drugs.2
According to researchers, your tongue has two sweet receptors in it, which evolved during the early times, when our ancestors ate a typically low-sugar diet. As the years went by, people's tongues were still not able to adapt to sweet treats. This is why when the receptors in your tongue are highly stimulated, it results in your brain sending out excessive reward signals whenever you eat something with sugar in it, which end up overriding your self-control mechanisms. This leads to addiction.
Dr. Robert Lustig, a professor of pediatrics at the University of California, San Francisco, wrote in The Atlantic that:
"The brain's pleasure center, called the nucleus accumbens, is essential for our survival as a species... When you consume any substance of abuse, including sugar, the nucleus accumbens receives a dopamine signal, from which you experience pleasure. And so you consume more. The problem is that with prolonged exposure, the signal attenuates, gets weaker. So you have to consume more to get the same effect -- tolerance. And if you pull back on the substance, you go into withdrawal. Tolerance and withdrawal constitute addiction."3Another major player in possible sugar addiction is the hormone leptin. It is responsible for telling the brain how energy that is stored from fat is to be used. Moreover, it targets taste receptors in your tongue, which could increase or decrease your food cravings. When you lack leptin or if there is a problem with your body's leptin receptors, then your chances of craving food will be bigger, and more often than not, sugar is always the first pick when it comes to combating cravings.
