Question: how many grams of natural sugar should a child have per day?
Answer: These numbers average out to about 6–9 teaspoons, or 25–37.5 grams, of sugar a day. Then, in 2016 the AHA took it a step further, stating that children and teens (ages 2–18) should limit their added sugars to less than 6 teaspoons per day and no more than 8 fl oz of sugary beverages per week.
