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 about 6 to 9 teaspoons, a threshold most people blow past before lunch. Here’s what the numbers actually look like and how to stay within them.
The Daily Limits, by Organization
The American Heart Association sets the most specific targets: no more than 36 grams (9 teaspoons) of added sugar per day for men and 25 grams (6 teaspoons) for women. Those limits translate to roughly 150 and 100 calories from sugar, respectively.
The World Health Organization frames it differently, recommending that free sugars make up less than 10% of your total daily calories. On a standard 2,000-calorie diet, that works out to about 50 grams, or 12 teaspoons. But the WHO goes further with a conditional recommendation: keeping sugar below 5% of total calories (roughly 25 grams) for additional health benefits, particularly for your teeth.
The FDA uses 50 grams per day as its Daily Value on nutrition labels, based on that same 2,000-calorie diet. This is the number you’ll see when a label tells you a food contains “20% DV” of added sugars. It’s worth knowing that this is the most generous of the major benchmarks. If you’re aiming for better outcomes, the AHA’s tighter limits are the ones most dietitians point to.
Added Sugar vs. Natural Sugar
These limits apply to added sugars, not the sugar naturally present in whole fruit, plain milk, or vegetables. Your body processes both types of sugar the same way at the molecular level. The difference is packaging: a whole apple delivers its sugar alongside fiber, water, and micronutrients, which slows absorption and limits how much you eat in one sitting. A glass of apple juice or a granola bar strips away that built-in brake system.
You don’t need to count the sugar in a banana or a handful of blueberries toward your daily cap. The health risks linked to sugar come from the added kind, the sugars mixed into foods during processing or preparation.
What Happens When You Eat Too Much
Excess added sugar doesn’t just cause weight gain. It sets off a chain of metabolic problems that compound over time. High sugar intake overloads the liver, which converts dietary carbohydrates into fat. When that happens repeatedly, fat accumulates in the liver itself, a condition called fatty liver disease that raises your risk for type 2 diabetes.
Too much added sugar also raises blood pressure and triggers chronic inflammation, both of which damage blood vessels. Together, these effects (higher blood pressure, inflammation, weight gain, diabetes, and fatty liver disease) are all linked to increased risk of heart attack and stroke. Sugar also happens to be the single most common dietary risk factor for cavities, and keeping intake below 5% of total calories minimizes tooth decay risk across your entire lifespan.
How to Read a Nutrition Label
Current FDA labels list “Added Sugars” as a separate line underneath “Total Sugars.” The word “includes” before “Added Sugars” tells you that the added sugar figure is part of the total, not in addition to it. You’ll also see a percent Daily Value, which is based on the 50-gram FDA benchmark.
To convert grams to teaspoons, divide by four. A yogurt with 16 grams of added sugar contains 4 teaspoons. A can of soda with 39 grams has nearly 10 teaspoons, which by itself exceeds the AHA’s daily limit for women and reaches the limit for men. Getting comfortable with this quick math is one of the most useful habits you can build.
Single-ingredient sweeteners like honey, maple syrup, and table sugar also carry added sugar labeling now, with the percent Daily Value listed either on the main panel or in a footnote.
Where Hidden Sugar Adds Up
The obvious culprits (soda, candy, desserts) are easy to spot. The less obvious ones are what push most people over the line. Ketchup, jarred pasta sauce, barbecue sauce, and salad dressings all frequently contain added sugar despite tasting savory. Protein bars and flavored yogurts can carry surprisingly high amounts; look for options where the grams of protein exceed the grams of sugar.
Flavored milks and coffee creamers, especially chocolate, vanilla, or strawberry varieties, are sweetened beyond whatever natural sugar the dairy contains. Granola, instant oatmeal, and most breakfast cereals are sweetened with sugar, honey, or both. Even nut butters often include added sugars for flavor and texture. Canned fruit packed in syrup rather than juice is another quiet source. None of these foods are inherently bad, but they make it easy to hit 40 or 50 grams of added sugar before you’ve had anything you’d think of as a treat.
Practical Ways to Stay Under the Limit
Start by auditing a single day. Write down everything you eat, check the added sugar lines, and total it up. Most people are genuinely surprised. From there, the biggest wins usually come from swapping sugary drinks for water or unsweetened versions, choosing plain yogurt over flavored, and picking breakfast options with less than 6 grams of added sugar per serving.
You don’t need to eliminate sugar entirely. The goal is keeping added sugar in the range of 25 to 36 grams per day, which leaves plenty of room for the occasional cookie or splash of honey in your tea. The people who succeed long-term tend to focus on reducing the hidden, routine sugar (the pasta sauce, the granola, the afternoon coffee drink) rather than white-knuckling their way through a zero-sugar plan.
