Question: how many grams of sugar in a teaspoon per day?
Answer: To keep all of this in perspective, it's helpful to remember the American Heart Association's recommendations for sugar intake. Men should consume no more than 9 teaspoons (36 grams or 150 calories) of added sugar per day. For women, the number is lower: 6 teaspoons (25 grams or 100 calories) per day.
