How much sugar per day?
For added sugar, the American Heart Association recommends at most 36 g a day for men and 25 g for women and children — roughly 9 and 6 teaspoons. The WHO sets the ceiling at 10% of your daily calories, ideally 5%. Pick your profile below and see your number in grams, teaspoons, and sugar cubes.
How it's calculated
- AHA limits: the American Heart Association recommends no more than 36 g of added sugar per day for men, and 25 g for women and children.
- WHO limits: the World Health Organization recommends keeping free sugars under 10% of daily energy, ideally under 5% (about 25 g on a 2,000-calorie diet). Sugar provides roughly 4 kcal per gram, so the calculator computes calories × 10% ÷ 4.
- Conversions: 1 teaspoon = 4.2 g of sugar; 1 sugar cube ≈ 4 g.
These limits cover added sugar — the whole fruit on your counter is not the problem.
