The problem with consuming so much sugar is that the constant influx of sugar into the bloodstream upsets the body's blood-sugar balance. This triggers the release of insulin, which the body uses to keep blood-sugar at a constant and safe level. It is important to realize that Insulin also promotes the storage of fat. So, when we consume high levels of sugar, we’re opening the door for rapid weight gain. 

Further, the glycemic index (a measure of how a given food affects blood-glucose levels), of foods is important. The lower the rating, the slower the absorption and digestion process. This process provides a more gradual, healthier infusion of sugars into the bloodstream. On the other hand, a high rating means that blood-glucose levels are increased quickly. This stimulates the pancreas to secrete insulin  to drop blood-sugar levels. These rapid fluctuations of blood-sugar levels are not healthy because of the stress they place on the body.

Recently, the American Heart Association released recommendations for specific levels and limits on the consumption of sugars. 

The statement says that most women should consume no more than 100 calories (about 25 grams) of added sugars per day. Most men should consume no more than 150 calories (about 37.5 grams) each day. That’s about six teaspoons of added sugar a day for women and nine for men.
