About the Sugar Intake Calculator
Added sugar is one of the easiest things to overdo without noticing, because it hides in drinks, sauces, breakfast foods and snacks. This calculator shows your recommended daily limit for added sugar based on official guidelines from the World Health Organization and the American Heart Association, and lets you compare it against how much you actually eat.
I never ask clients to fear sugar, but I do want them to see it clearly. Putting a simple gram and teaspoon number on the recommendation tends to be a gentle wake up call, especially once people realize how much is in a single sweetened drink.
What the guidelines say
The World Health Organization advises keeping free sugars under 10 percent of your daily calories, and ideally under 5 percent for extra health benefit. The American Heart Association sets a clearer daily cap on added sugar: about 25 grams (6 teaspoons) for women and 36 grams (9 teaspoons) for men. The calculator shows all three figures so you can pick the target that suits you.
Added sugar versus natural sugar
These limits apply to added or free sugars, the sugar put into foods and drinks plus that found in syrups, honey and fruit juice. They do not include the natural sugars in whole fruit, vegetables and plain dairy, which come packaged with fiber, water and nutrients that slow absorption. You do not need to worry about the sugar in a whole apple the way you do about the sugar in a soda.
Easy ways to cut back
The biggest single win for most people is sugary drinks, since they add a lot of sugar with no fullness in return. After that, check labels on cereals, yogurts, sauces and granola, where sugar often hides. You do not have to eliminate sugar, just bring it within a sensible range. Swapping, halving and choosing whole foods over processed ones usually gets you there comfortably.

Frequently Asked Questions
The American Heart Association recommends no more than about 25 grams (6 teaspoons) of added sugar a day for women and 36 grams (9 teaspoons) for men. The World Health Organization suggests keeping free sugars under 10 percent of your calories, and ideally under 5 percent. These apply to added sugar, not the natural sugar in whole fruit and plain dairy.
No. The limits are for added or free sugars, which includes table sugar, sugar in processed foods, and the sugar in honey, syrups and fruit juice. The natural sugar in whole fruit, vegetables and plain milk is not counted, because it comes with fiber and nutrients that change how your body handles it.
One teaspoon of sugar is about 4 grams. So the AHA limit of 25 grams for women is roughly 6 teaspoons, and 36 grams for men is about 9 teaspoons. A single can of regular soda can contain around 35 to 40 grams, close to or above a full day's limit.
On modern labels, added sugars are listed separately under total sugars. They include any sugars added during processing, plus sugars from syrups, honey and concentrated fruit juice. Checking this line is the quickest way to keep your daily total within the recommended range.
