What does this tool do?
Health guidelines generally recommend keeping added sugar below 10% of daily calories, with additional benefit below 5%. This calculator converts those shares into grams and compares them with the stricter American Heart Association caps.
The Formula
Added sugar (g) = Calories × Share of calories ÷ 4 kcal/gFrequently Asked Questions
Does the limit include sugar from fruit?
No. The limit applies to added sugars, including syrups, honey and concentrated fruit juice. Whole fruit contains fibre and is treated differently in most guidelines.
Are artificial sweeteners a substitute?
They can reduce added sugar, but they are not required for a healthy diet. Water, unsweetened drinks and whole foods are the simplest swaps.
