How Much Added Sugar Is Too Much? Limits in Grams, Teaspoons, and Calories
October 21, 2026
Sugar guidelines are usually given as a share of daily energy, which makes them awkward to apply at the grocery store. Converting percentages to grams helps. The World Health Organization recommends that free sugars supply less than 10% of total energy, and suggests that going below 5% brings additional benefits. On a 2,000-calorie diet, 10% is 200 calories, which is 50 grams of sugar (at 4 calories per gram), and 5% is 25 grams.
The American Heart Association gives a more specific limit for added sugars: no more than 25 grams per day for most women and 36 grams for most men. A teaspoon of sugar is about 4.2 grams, so 50 grams is almost 12 teaspoons and 25 grams is just under 6.

Free sugars include sugars added to foods and drinks, plus sugars naturally present in honey, syrups, and fruit juices. Added sugars are those put into products by manufacturers or at the table. Sugars naturally contained in whole fruit, vegetables, and plain milk are not counted in these limits because they come packaged with fiber, water, and nutrients that slow absorption and increase fullness.
Fruit juice counts as free sugar even without added sweetener, which is why a glass of orange juice, with about 21 grams of sugar per 8 ounces, uses a sizable share of your allowance.
What Common Foods Contain
The sugar content of everyday products adds up quickly. A 12-ounce can of cola has roughly 39 grams, which is close to the whole day's allowance for women under AHA guidance. A flavored yogurt can have 15 to 25 grams, a granola bar 8 to 15, a tablespoon of ketchup 4, a slice of cake 25 to 40, and a sweetened coffee drink 30 to 60 grams. Check labels for 'Added Sugars', which many countries now require, and for ingredient names like sucrose, high-fructose corn syrup, dextrose, and fruit juice concentrate.
| Item | Approx. sugar | Teaspoons | Share of a 50 g limit |
|---|---|---|---|
| 12 oz cola | 39 g | 9.3 | 78% |
| Flavored yogurt (6 oz) | 18 g | 4.3 | 36% |
| Granola bar | 11 g | 2.6 | 22% |
| Tablespoon of ketchup | 4 g | 1 | 8% |
| Glass of orange juice (8 oz) | 21 g | 5 | 42% |
| Slice of cake | 30 g | 7.1 | 60% |
Why Limits Exist
High intakes of added sugar are associated with weight gain, dental decay, and higher risk of type 2 diabetes and cardiovascular disease. Sugar-sweetened drinks are of particular concern because liquid calories do not satisfy hunger as much as solid food. For children, limits are lower, and the WHO and several national authorities recommend avoiding added sugars for children under two.
These are population-level guidelines and not rules that suddenly make a single dessert harmful. The pattern over weeks and years matters.
Practical Ways to Cut Back
Swap sugary drinks for water, sparkling water, or unsweetened tea, since drinks are the largest source of added sugar for many people. Choose plain yogurt and add fruit. Read labels on sauces, breads, and cereals. Reduce sugar in coffee gradually by a half teaspoon at a time so that your taste adjusts. Keep desserts as planned treats rather than daily habits. Eating enough protein and fiber at meals also reduces cravings.
Artificial sweeteners reduce calories but their long-term effects on weight and health are still debated, so many experts suggest using them to transition rather than as a permanent solution.
Setting a Personal Target
Calculate 10% of your calorie target and divide by four. For a 1,800-calorie diet, that is 45 grams; for 2,500 calories, 62 grams. Track your usual intake for a few days to see where you stand, and then cut the biggest sources first.
