Zero sugar, sugar free, no sugar added: what the words on the package mean
By zerosugar · November 8, 2026
Zero sugar and sugar free mean a serving has almost no sugar at all. No sugar added means no sugar was put in, but the food can still have its own natural sugar, and it may use sweeteners. The Nutrition Facts panel tells you which one you have.
Zero sugar and sugar free
These two mean the same thing. The FDA lets a package say it only when a serving has less sugar than a small limit it sets, so the label can round down to zero. The rest of the sweetness comes from sweeteners.
No sugar added
No sugar added means no sugar, and no ingredient that contains sugar, was put in. Sweeteners without sugar are still allowed. Tomato sauce, applesauce and dried fruit can still carry plenty of natural sugar. For foods like these, zerosugar picks a swap with no added sugar and fewer carbs than the original.
Reduced sugar and less sugar
Reduced sugar means less than the regular version, not none. It is worth checking the panel, because a reduced-sugar food can still have more sugar than a zero-sugar one.
What the front of the package does not tell you
None of these words say anything about carbs. A zero-sugar product can still have carbs from flour, starch or sweeteners. Read Total Carbohydrate on the panel, or see it on any zerosugar product page.

Questions
What is the difference between zero sugar and no sugar added?
Zero sugar and sugar free mean a serving has almost no sugar at all. No sugar added means no sugar was put in, but the food can still have its own natural sugar, and it may use sweeteners. The Nutrition Facts panel tells you which one you have.
Is sugar free the same as zero sugar?
Yes. Both are allowed only when a serving has less sugar than the FDA's small limit, so the label can say zero.
Can no-sugar-added food have sugar?
Yes. It can have natural sugar from fruit, milk or vegetables, and it can contain sweeteners. Check Total Sugars on the panel.
