Sugar has drug-like effects in the reward centre of the brain. Scientists have proven that sweet foods—along with salty and fatty foods—can produce addiction-like effects in the human brain, more potent than cocaine.

Additional studies on brain activity have shown that sugar alters our brain’s reward system, which results in a loss of self-control and then further drives overeating.

Even a single instance of elevated glucose in the bloodstream can be harmful to the brain, resulting in slowing down of cognitive function and  deficits in memory and attention. Even more frightening is the inflammatory and destructive effect of sugar on the brain: Alzheimer’s is now recognised as a type 3 diabetes. And many chronic diseases, including cholesterol, atherosclerosis and heart disease have high sugar intake at the core of their origin.
