“Sugar consumption itself has become a disease. Over-consumption can lead to hypoglycemia, diabetes, heart disease, and chronic tiredness. Excess sugar consumption is one of the major causes for fatigue. Not only is sugar a major culprit, the consumption of refined carbohydrates that quickly turn to sugar in our blood is equally damaging.

Many people actually use sugar as medicine. Sugar tends to change the way the blood-brain barrier selects appropriate amino-acid building blocks of brain chemicals. Refined carbohydrate consumption increases the level of the amino acid tryptophan, which is the building block of the brain chemical serotonin. Serotonin is a proven tranquilizer. Sugar creates a cycle of craving and bingeing. It is highly addictive”. ~ Naturalways.com
