Hi....5 grams is equal to 1 teaspoon. So, you're getting less than what's in a can of soft drink. What kind of sugar is in your drink?
A 12oz canned soft drink averages 35 - 50 grams of sugar, so you'd definitely be consuming much less.
Your body also needs sugar to burn, not fake sugar which screws with the pancreas and insulin output.
It's all a matter of perspective!
