how much sugar a day does the average human eat
The AHA says that adult women should get 5 teaspoons (20 grams) of sugar per day, adult men 9 teaspoons (36 grams), and children 3 teaspoons (12 grams). To put that in perspective, a can of soft drink alone can have as many as 40 grams, or about 10 teaspoons of sugar.
