Most adults should limit added sugar to no more than 25 to 36 grams per day, depending on sex. That’s roughly 6 to 9 teaspoons. The average American adult consumes about 17 teaspoons daily, nearly double the upper end of that range.
Recommended Limits for Adults
The American Heart Association sets the most widely cited daily caps: no more than 36 grams (9 teaspoons, or about 150 calories) of added sugar per day for men, and no more than 25 grams (6 teaspoons, or about 100 calories) for women. The World Health Organization frames it differently, recommending that free sugars stay below 10% of your total daily calories, with an ideal target of under 5%. On a 2,000-calorie diet, 10% works out to about 50 grams, and 5% to about 25 grams.
The FDA uses that 50-gram figure as the Daily Value on nutrition labels. So when you see a percent Daily Value for added sugars on a product, it’s based on a 2,000-calorie diet with a 50-gram ceiling. That’s more lenient than the AHA recommendations, which is worth keeping in mind if you’re using label percentages to guide your choices.
Limits for Children
Children need stricter limits. The American Academy of Pediatrics recommends no added sugar at all for children under 2 years old. For kids ages 2 and up, the cap is 25 grams (about 6 teaspoons) per day, the same as the adult female limit. The Dietary Guidelines for Americans goes further, recommending that children younger than 11 have no added sugar, though this is a newer and more aggressive target that many families find difficult to meet.
How Much Americans Actually Consume
CDC data from 2017 to 2018 shows that American adults average 17 teaspoons of added sugar per day, roughly 68 grams. Men average 19 teaspoons and women average 15. Both figures far exceed every major guideline. The gap is smallest among non-Hispanic Asian adults, who average about 10 teaspoons daily, and widest among non-Hispanic Black adults, who average 19 teaspoons. Hispanic adults average 16 teaspoons, and non-Hispanic White adults average 17.
Much of this excess comes from sweetened drinks, flavored yogurts, cereals, sauces, and packaged snacks, foods where sugar is added during processing but isn’t always obvious from the product name alone.
Added Sugar vs. Natural Sugar
Your body breaks down added and natural sugars the same way at a molecular level. The difference is context. Sugar in whole fruit comes packaged with fiber, water, and other nutrients that slow absorption and limit how much you consume in a sitting. A medium apple has about 19 grams of sugar, but you’re unlikely to eat three apples back to back. A bottle of sweetened iced tea can deliver 40 or 50 grams in a few minutes with no fiber to slow things down.
This is why guidelines focus on added sugars rather than total sugars. The naturally occurring sugar in fruit, plain milk, and vegetables isn’t something most people need to worry about. It’s the sugar added during food processing, plus sweeteners like honey, maple syrup, and table sugar, that drives overconsumption.
What Excess Sugar Does to Your Body
Consistently exceeding sugar limits doesn’t just add empty calories. High intake of rapidly absorbed sugars, especially from sweetened beverages, raises blood sugar quickly and forces your body to produce large spikes of insulin. Over time, this pattern can lead to insulin resistance, where your cells stop responding efficiently to insulin’s signal to absorb glucose. Insulin resistance is a core driver of type 2 diabetes and metabolic syndrome.
Fructose, which makes up about half the sugar in both table sugar and high-fructose corn syrup, gets processed primarily in the liver. When you consume large amounts, the liver converts the excess into fat through a process that raises triglycerides, lowers protective HDL cholesterol, and promotes the accumulation of visceral fat (the deep abdominal fat surrounding your organs). This combination of high triglycerides, low HDL, and increased belly fat is a hallmark of metabolic syndrome and raises the risk of heart disease.
High-sugar diets also increase markers of chronic inflammation throughout the body, which independently raises the risk of type 2 diabetes and cardiovascular disease.
How to Read Sugar on a Nutrition Label
Current FDA labels list both “Total Sugars” and “Includes X g Added Sugars” directly beneath it. Total sugars covers everything, including the naturally occurring sugar in ingredients like milk or fruit. The added sugars line is the number that matters for tracking your intake against daily limits.
The label also shows a percent Daily Value for added sugars. A product with 5% DV or less per serving is considered low in added sugar. A product at 20% DV or more is high. Single-ingredient sweeteners like honey, maple syrup, and table sugar are required to list their added sugar content too, sometimes in a footnote rather than the main panel.
To convert grams to teaspoons, divide by four. A granola bar with 12 grams of added sugar contains 3 teaspoons. A can of soda with 39 grams contains nearly 10 teaspoons, which alone exceeds the daily limit for women and hits the limit for men.
Practical Ways to Stay Within the Limit
The single most effective change is cutting sweetened drinks. Soda, sweet tea, lemonade, energy drinks, and flavored coffee drinks are the largest source of added sugar in the American diet. Replacing even one daily sweetened beverage with water or unsweetened alternatives can eliminate 30 to 50 grams in a single step.
Beyond beverages, watch for sugar hiding in foods that don’t taste particularly sweet: pasta sauces, salad dressings, bread, flavored oatmeal, and condiments like ketchup and barbecue sauce. Comparing brands helps, because added sugar content can vary dramatically between two products on the same shelf. A flavored yogurt might contain 15 grams of added sugar while a competing brand uses 6 grams. Those differences compound across a full day of eating.
Cooking more meals from whole ingredients gives you natural control over sugar intake, since most added sugar enters the diet through processed and pre-packaged foods rather than through a sugar bowl on the kitchen counter.
