Dr. Robert Lustig, a professor of pediatrics at theUniversity 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.”
Another 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 combatting cravings.
Too much sugar can lead to detrimental effects to your health. I counted at least 76 ways (yes, you read that right!) in which sugar can cause serious health risks for you. These hazards are divided into four categories: Increased Risk of Diseases and Sicknesses, Nutrient Imbalance or Deficiency, Bodily Impairments, and Behavioral Changes.
