What Is Added Sugar — and Why Does It Matter?
Not all sugar in food is created equal. Natural sugars occur in whole foods like fruit (fructose) and dairy (lactose). Added sugars, by contrast, are introduced during processing or preparation — think the sugar stirred into a flavored yogurt or the corn syrup in a store-bought granola bar.
This distinction matters because added sugars contribute calories without meaningful nutrients. Over time, diets high in added sugar have been associated in research with increased risk of weight gain, dental cavities, and conditions like type 2 diabetes — though individual health outcomes depend on many factors. You can learn more about how to spot these ingredients on packaging in our guide to reading a nutrition label.
Added Sugar
Sugars and syrups introduced to a food during processing or preparation, as distinct from naturally occurring sugars in whole foods like fruit or milk.
Natural Sugar
Sugar found inherently in whole, unprocessed foods such as lactose in dairy or fructose in fruit. These are not counted as added sugars on a nutrition label.
High-Fructose Corn Syrup (HFCS)
A common liquid sweetener derived from corn starch, widely used in sodas, condiments, and packaged baked goods as a cost-effective added sugar.
Grams of Added Sugars
The measurement used on the Nutrition Facts panel to indicate how much added sugar a food contains per serving. One teaspoon of sugar equals approximately 4 grams.
Free Sugars
A term used by the World Health Organization that includes added sugars plus sugars naturally present in honey, syrups, and unsweetened fruit juices — but not sugars inside intact whole fruit.
Sugar Alcohols
Reduced-calorie sweeteners such as xylitol, sorbitol, and erythritol. They are not classified as added sugars but may still affect blood sugar levels in some individuals.

Where Added Sugar Hides in Common Family Foods
Many foods marketed to families carry surprisingly high amounts of added sugar — even savory ones. Recognizing the most common sources is the first practical step toward making more informed choices.
| Added sugars line on Nutrition Facts | Required by the FDA since 2020 for most packaged foods (U.S. Food & Drug Administration) |
| Top source of added sugar in the US diet | Sugar-sweetened beverages (sodas, sports drinks, fruit drinks) (Dietary Guidelines for Americans) |
| Common hidden sources | Flavored yogurt, ketchup, salad dressing, instant oatmeal, bread |
| Number of names for added sugar on labels | More than 60 recognized terms (U.S. Food & Drug Administration) |
| Teaspoons per gram of sugar | ~4 grams = 1 teaspoon |
| Age group with strictest guideline | Children under 2: added sugars not recommended (American Academy of Pediatrics / American Heart Association) |
Added sugar goes by many names on ingredient labels. The FDA currently recognizes more than 60 terms that indicate added sugar, including high-fructose corn syrup, cane juice, maltose, dextrose, fruit juice concentrate, and agave nectar. When multiple sweetener names appear in a single ingredient list, their combined contribution can be substantial even if no single one appears near the top of the list.

17 tsp
Average daily added sugar intake for US adults
According to analysis of National Health and Nutrition Examination Survey (NHANES) data cited by the American Heart Association.
~50%
Of US children exceed recommended added sugar limits
Estimates from the Dietary Guidelines for Americans advisory committee reports suggest roughly half of children consume more added sugar than recommended.
39g
Added sugar in a typical 12-oz can of soda
A standard 12-ounce cola contains approximately 39 grams of added sugar, already exceeding the AHA's daily limit for most women.
General Guidelines on Daily Limits
Several major health organizations publish guidance on added sugar intake. While exact recommendations vary, here is a general reference:
- The American Heart Association (AHA) suggests limiting added sugar to no more than 25 grams (about 6 teaspoons) per day for most women and 36 grams (9 teaspoons) for most men.
- For children under 2, the AHA and the American Academy of Pediatrics (AAP) recommend avoiding added sugars entirely when possible.
- For children ages 2–18, the AHA recommends no more than 25 grams per day, with particular attention to sugar-sweetened beverages.
- The Dietary Guidelines for Americans suggest limiting added sugars to less than 10% of total daily calorie intake for those aged 2 and older.
These are population-level guidelines, not personal prescriptions. A registered dietitian can help translate them into realistic meal planning for your household. Our article on family nutrition through every life stage covers how dietary needs shift from toddlerhood through adulthood.
Always consult a qualified healthcare provider or registered dietitian before making significant changes to your family's diet, especially for children, pregnant individuals, or anyone managing a chronic health condition.
