Low Sugar Claim: Why FDA Doesn't Allow It, and What Does

Low sugar claims: FDA hasn't defined low sugar, so it can't be used; sugar free, no added sugar and reduced sugar, their conditions, and a checker.

FDA has defined "sugar free", "no added sugar" and "reduced sugar", and it hasn't defined "low sugar". Nutrient claims can only be made the way the rules define them, so "low sugar", "low in sugar" and "lightly sweetened" as a level aren't available. Sugar free means less than 0.5 grams of sugars per reference amount, and a statement that the food isn't low calorie unless it is. No added sugar means nothing that adds sugar went in, including concentrated fruit juice. Reduced sugar means 25% less than the regular version, with the comparison printed. In the example below, a Michigan preserves maker works out what its lower-sugar cherry spread can say.

The short version

  • "Low sugar" isn't defined by FDA, so it can't be used as a claim.
  • Sugar free: under 0.5 g per reference amount, with the calorie statement.
  • No added sugar: no sugars added, and no fruit juice concentrate either.
  • Reduced sugar: 25% less than the regular version, with the comparison.
  • Any claim brings a Nutrition Facts panel.
  • A lower-sugar jam may not meet the standard for jam or preserves.
  • TaroStack keeps each recipe by weight, so the sugar in a batch is the recipe's. More below.

The claims

Claim The test What else the label needs
Low sugar Not defined Not allowed
Sugar free Under 0.5 g per reference amount and serving Not a reduced calorie food, not a low calorie food, or not for weight control, unless it is
No added sugar No sugars or sugar-containing ingredients added, including juice concentrate Not low or reduced calorie, unless it is, and a pointer to the Nutrition Facts
Reduced sugar 25% less than a reference food The reference food, the percentage and the grams of both

Fruit's own sugar counts toward sugars, so most fruit spreads can't be sugar free. Every condition of no added sugar, worked through, is in no added sugar label. How a jam's name depends on its sugar is in standard of identity food, and what a jar costs in how to price jam.

The rules

Rule Where
Only defined claims A nutrient content claim may be made only as the regulations define it (21 CFR 101.13(b))
Sugar free Under 0.5 g of sugars per reference amount and serving, with the calorie statement (21 CFR 101.60(c)(1))
No added sugar No sugars added, and no ingredient with added sugars such as jam, jelly or concentrated fruit juice (21 CFR 101.60(c)(2))
Reduced sugar At least 25% less per reference amount than a reference food, with the comparison (21 CFR 101.60(c)(5))

This is general information, not legal advice.

An example: three cherry products

Old Mission Preserves, the made-up preserves maker in Traverse City, Michigan, I use in these examples, wanted "low sugar" on a new cherry spread. Per tablespoon, the reference amount for jams:

Product Sugars per tbsp Against the preserves What it can say
Tart cherry preserves, the regular 10 g No sugar claim
Cherry fruit spread, less sugar 6 g 40% less Reduced sugar, with the comparison
Cherry spread, apple juice concentrate 7 g 30% less Reduced sugar; not no added sugar

"Low sugar" was off the table for both. The less-sugar spread says "Reduced sugar: 40% less sugar than our tart cherry preserves. 6 g vs 10 g per tablespoon." The spread sweetened with apple juice concentrate can't say no added sugar, because juice concentrate counts. Neither has enough sugar to meet the standard for preserves, so both are called fruit spread, in jam labeling requirements.

Download the sugar claim checker. One sheet: each product, its sugars per reference amount, the regular version's sugars, and whether any sugar or juice concentrate is added; the reduction and the claims it can carry fill in. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.

Where this stops working

The numbers are right for the recipe tested. Riper cherries carry more sugar, a batch made with the regular sugar by habit, or a new juice concentrate changes the sugars while the jar still says reduced sugar.

How TaroStack does it

TaroStack keeps each recipe by weight, so the sugar in a batch is the recipe's sugar.

Recipes by weight. Each spread is its own recipe, with its ingredients by weight.

Batches by lot. Each batch records which ingredient lots it used and how many jars it filled.

Recalls. If a batch was made from the wrong recipe, one report shows every customer who got it.

Which recipe a batch followed Remembered Each batch from its recipe
Sugar used in a batch Not recorded From the recipe and batch
Who got a wrong batch Invoices One recall report

Recipes, batches and recalls are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.

Questions people also ask

Can you say low sugar on a food label?

No: FDA hasn't defined low sugar, and nutrient claims can only be made as the rules define them.

What does reduced sugar mean?

At least 25% less sugar than the regular version, with the reference food, the percentage and the grams of both on the label.

Can fruit juice concentrate be in a no added sugar product?

No: concentrated fruit juice counts as an ingredient with added sugars.

What does sugar free mean?

Less than 0.5 g of sugars per reference amount and serving, with a statement that the food isn't low calorie unless it is.
