Words on the front of a box are chosen by people who want you to buy the box. Words on the back are chosen by the government. Let's read both and see where they disagree.
Try this: the fridge audit
Open your fridge. Pull out three drinks with any kind of sugar claim on the front: "no added sugar," "no sugar added," "unsweetened," "reduced sugar," "lightly sweetened." Line them up.
Now flip each one and find two lines: Total Sugars and, indented underneath it, Includes Added Sugars. Write both numbers on a sticky note and put it on the front.
Now the front and the back are having a conversation. It is usually an interesting one.
What "no added sugar" actually means
This phrase is regulated. The FDA defines it, and the definition is narrow and specific.
"No added sugar" means: no sugar, and no ingredient that is basically sugar, was added during processing. No cane sugar, no corn syrup, no honey, no concentrated fruit juice used as a sweetener. The sugar that's in the product got there on its own, from the fruit or the milk it was made from.
That's it. That's the whole promise. Notice what the promise does not say. It does not say "low sugar." It does not say "less sugar than the other box." It does not say anything about how much sugar is inside. It only says nobody put extra in.
Where that goes wrong
Consider grape juice. Grapes are about 16% sugar by weight. Squeeze them and you get a liquid that is, quite naturally, loaded with sugar. Put six ounces in a box and you have about 20 grams of sugar. Nobody added a thing.
"No added sugar." True. Five teaspoons. Also true.
Apple juice, same story: around 24 grams in an 8-ounce glass, all from apples. Orange juice, about 21. These are real fruit, no additives, and they carry more sugar per ounce than a lot of sodas. The label is honest and the glass is still full.
So "no added sugar" tells you about the recipe. It tells you nothing about the dose.
The cousins: sugar-free, unsweetened, reduced
While we're reading, four phrases that look alike and aren't:
No added sugar / no sugar added. Nothing added during processing. Natural sugar can be anything.
Sugar-free. Less than half a gram of sugar per serving. This one actually means low. It also usually means artificial sweeteners are doing the sweetening, so check the ingredients.
Unsweetened. No sweeteners of any kind added, sugar or artificial. Same logic as "no added sugar," but it also rules out sucralose and friends.
Reduced sugar / less sugar. At least 25% less than the regular version of that same product. If the regular version had 28 grams, "reduced" can still be 21.
Four phrases. Only one of them, sugar-free, puts a ceiling on the number.
The concentrate trick
Here is a detail the front of the box would prefer you didn't know.
Fruit juice concentrate, when it's used to sweeten something that isn't 100% juice, counts as added sugar on the label. The FDA figured out years ago that "sweetened with fruit juice concentrate" was a way to put sugar in and keep "no added sugar" on the front. So now, if a "juice drink" or a flavored water gets its sweetness from apple or grape concentrate, that sugar shows up on the "Includes Added Sugars" line.
Which is good news. It means the back of the box is harder to fool than the front. Read the back.
What to actually look for
You want two numbers, and you want them both small:
- Total Sugars in single digits. This is the dose. This is the one that matters for a kid's teeth, appetite, and the 3pm crash.
- Includes Added Sugars: 0 g. This is the recipe. Fruit did the sweetening.
A drink that gets both right is rare in the juice aisle, because juice is concentrated fruit sugar by nature. The way to get both is to start with real fruit and stop before the sugar piles up, then put something back that the juicing took out.
That's how we made Wonderade. 3 grams of total sugar, 0 grams added, in a juice that still tastes like one. Alongside the sugar: 8 grams of protein and 4 grams of fiber, so it lands like a snack instead of a syrup. Both numbers small, and the back of the box agrees with the front.

The ten-second version
Flip the box. Two lines. Total Sugars, single digits. Added Sugars, zero. Everything else on the package is decoration.
FAQ
What does "no added sugar" mean on juice? Under the FDA definition, no sugar or sugar-containing ingredient (cane sugar, syrup, honey, concentrated juice as a sweetener) was added during processing. It says nothing about how much natural sugar the juice contains, which for 100% fruit juice is often 20 grams or more per serving.
Is "no sugar added" the same as sugar-free? No. "Sugar-free" means less than 0.5 g of sugar per serving. "No sugar added" only means nothing was added; a no-sugar-added grape juice can still have 20 g per box.
Does fruit juice concentrate count as added sugar? When concentrate is used to sweeten a product that isn't 100% juice, yes, the FDA counts it as added sugar and it appears on the "Includes Added Sugars" line.
Is 100% juice with no added sugar healthy for kids? It has no added sugar and brings vitamin C, but it's still concentrated fruit sugar without fiber. The American Academy of Pediatrics limits it by age: none under 1, up to 4 oz for ages 1 to 3, 4 to 6 oz for ages 4 to 6, up to 8 oz for ages 7 and up.
Which juice boxes have the least sugar? Look for single-digit Total Sugars and 0 g Added Sugars on the back panel. Wonderade is 3 g total, 0 g added, with 8 g protein and 4 g fiber per box.
