Most major health organizations recommend limiting added sugar to no more than 25 to 36 grams per day, depending on your sex and calorie needs. That translates to roughly 6 to 9 teaspoons. The latest U.S. Dietary Guidelines go even further, stating that no amount of added sugar is considered part of a nutritious diet. Here’s what the specific numbers look like and how to put them into practice.
The Official Numbers
Several organizations have set daily limits, and they differ slightly in how they frame the recommendation:
- American Heart Association: No more than 36 grams (9 teaspoons) per day for men, and no more than 25 grams (6 teaspoons) per day for women.
- World Health Organization: Less than 10% of total daily calories from free sugars, with a further suggestion to stay below 5%. On a 2,000-calorie diet, 10% works out to about 50 grams (12.5 teaspoons), and 5% is about 25 grams.
- U.S. Dietary Guidelines (2025–2030): The newest edition takes the strictest stance yet, noting that “no amount of added sugars or non-nutritive sweeteners is recommended or considered part of a healthy or nutritious diet.” Previous editions had set the ceiling at 10% of daily calories.
For children aged 2 and older, the American Academy of Pediatrics recommends staying under 25 grams (about 6 teaspoons) per day. For children under 2, the guidance is straightforward: avoid added sugar entirely.
Added Sugar vs. Total Sugar
Not all sugar on a nutrition label counts the same way. “Total Sugars” includes the sugar naturally present in foods like fruit, milk, and vegetables. “Added Sugars,” listed just below on the label, covers only the sugars introduced during processing: table sugar, honey, syrups, and sugars from concentrated fruit juices. The daily limits above apply to added sugars specifically. The natural sugar in a whole apple or a glass of plain milk is not part of the concern, because those foods come packaged with fiber, vitamins, and other nutrients that slow absorption and provide real nutritional value.
One quick conversion makes label reading easier: 4 grams of sugar equals 1 teaspoon. So if a flavored yogurt lists 16 grams of added sugars, that’s 4 teaspoons in a single serving.
Why the Limits Exist
Your body handles small amounts of sugar without much trouble. The small intestine processes modest doses of fructose efficiently before it ever reaches the liver. But when intake climbs too high, that intestinal capacity gets overwhelmed, and excess fructose spills into the liver and gut bacteria, triggering a cascade of problems.
In the liver, that overflow kicks off rapid fat production. Excess fructose gets converted into fatty acids, which accumulate in liver tissue and enter the bloodstream. Over time, this promotes insulin resistance, meaning your cells stop responding properly to the hormone that controls blood sugar. The result is a slow drift toward higher blood pressure, chronic inflammation, and elevated uric acid levels, which contribute to oxidative damage throughout the body.
Fructose also reduces satiety signals, so foods high in added sugar tend to leave you less satisfied than their calorie count would suggest. You eat more without feeling full. This combination of invisible fat buildup, weakened hunger signals, and chronic low-grade inflammation is what links excess sugar intake to heart disease, type 2 diabetes, and fatty liver disease.
Where Hidden Sugar Shows Up
Desserts and soda are the obvious sources, but a surprising amount of added sugar hides in foods most people consider savory or healthy. Ketchup, barbecue sauce, jarred pasta sauce, and salad dressings all frequently contain added sugars. Granola, instant oatmeal, and many breakfast cereals are sweetened with sugar or honey. Flavored yogurts and protein bars, often marketed as health foods, can pack substantial amounts. Even nut butters sometimes include added sugar for flavor and texture.
Drinks are the single largest contributor for many people. Regular soda is well known, but sports drinks, energy drinks, bottled iced teas, and coffeehouse beverages can contain just as much. Flavored milks and nondairy alternatives in chocolate, vanilla, or strawberry varieties are another easy place to accumulate sugar without realizing it. Canned fruit packed in syrup rather than juice is another quiet source worth checking.
How to Read Labels Effectively
The most practical habit is scanning the “Added Sugars” line on the Nutrition Facts panel. It appears indented beneath Total Sugars, preceded by the word “Includes.” If a container of flavored oat milk shows 12 grams of total sugars and 7 grams of added sugars, the remaining 5 grams come naturally from the oats themselves. Your daily budget of 25 to 36 grams fills up fast once you start tracking those added grams across meals and snacks.
Sugar also goes by dozens of names in ingredient lists. You don’t need to memorize them all. A reliable shortcut: anything ending in “-ose” (sucrose, dextrose, maltose) is a sugar. Honey, agave, cane juice, rice syrup, and fruit juice concentrate all count as added sugars despite sounding more natural.
What About Sugar Substitutes?
Replacing sugar with zero-calorie sweeteners might seem like an easy workaround, but the evidence is less encouraging than you’d expect. A WHO review found that non-sugar sweeteners, including stevia, aspartame, sucralose, and others, do not provide any long-term benefit in reducing body fat in adults or children. More concerning, the review identified a possible link between long-term use and increased risk of type 2 diabetes and cardiovascular disease, though the WHO noted that these findings could be partly influenced by the existing health profiles of the people studied.
The one exception in the WHO guidance: people who already have diabetes may still find sugar substitutes useful for managing blood sugar. For everyone else, the recommendation leans toward reducing sweetness overall rather than swapping one sweetener for another.
Practical Ways to Stay Within the Limit
Cutting back doesn’t require eliminating sugar completely. A few targeted swaps make the biggest difference. Choosing plain yogurt over flavored versions can save 10 to 15 grams of added sugar in a single serving. Drinking water, sparkling water, or unsweetened tea instead of sweetened beverages eliminates what is often the largest single source in most diets. Buying canned fruit in juice rather than syrup, choosing unsweetened nut butters, and making your own salad dressing with oil and vinegar are small changes that compound across the day.
Breakfast tends to be the meal where sugar sneaks in most aggressively. Swapping sweetened cereal or instant oatmeal for plain oats topped with fresh fruit gives you natural sweetness with fiber that slows sugar absorption. Over a few weeks, your palate adjusts, and foods that once tasted normal start to taste noticeably sweeter.
