What “no added sugar” really means
In everyday language, “no added sugar” sounds as if nobody poured sugar into the recipe. Regulators look more closely. In the United States, 21 CFR 101.60(c)(2) sets conditions covering added sugars, some sugar-containing ingredients, processes that increase sugar content, the reference food and accompanying calorie information. Not adding table sugar is only part of the assessment.
In the European Union, the European Commission's nutrition-claims guidance states that a product using “with no added sugars” must not contain added mono- or disaccharides or other foods used for their sweetening properties. If sugars occur naturally, the label should also indicate that it contains naturally occurring sugars.
Neither definition says the drink must contain zero total sugar. Fruit and milk ingredients can contribute sugar before a manufacturer adds anything. For a consumer, the next question should be how many grams of sugar the finished drink contains.
What “sugar-free” means in the US and EU
“Sugar-free” is a claim about the finished product. In the United States, for ordinary foods and beverages, the federal rule generally requires less than 0.5 g of sugars per reference amount customarily consumed and per labeled serving. It also has ingredient and calorie-claim conditions. A low analytical number alone is not enough to approve every packaging statement.
For drinks marketed in the EU, the “sugars-free” threshold is no more than 0.5 g of sugars per 100 mL. That is a different measurement basis. Comparing a US per-serving number with an EU per-100 mL figure without adjusting the units can mislead the reader.
Sugar-free also does not automatically mean calorie-free. The US rule can require a notice that a product is not low or reduced in calories when those conditions are not met. The FDA's guidance to manufacturers explains this point. Calorie claims are a separate question from sugar claims.
Reading Total Sugars and Added Sugars on US packs
The US Nutrition Facts panel makes two quantities visible. “Total Sugars” includes both sugars naturally present in ingredients and any added sugars. The line beginning “Includes” states how many grams of Added Sugars are within that total. Do not add those two numbers together.
Imagine a hypothetical fruit drink showing 12 g Total Sugars and 0 g Added Sugars per labeled serving. That combination is possible because naturally occurring sugars may remain in the drink. It is not sugar-free under the US numerical standard. Whether “no added sugar” is permitted still depends on the other claim conditions.
A different fictional drink might show 16 g Total Sugars and 12 g Added Sugars. It has both added and non-added sugars. The remaining difference does not identify exactly which ingredient supplied it. The FDA's guide to Added Sugars explains how the two lines relate.
Reading sugar on EU beverage labels
For most EU prepacked foods, the nutrition declaration includes carbohydrates and sugars expressed per 100 g or 100 mL. A per-portion figure may be added. Unlike the standard US Nutrition Facts panel, the mandatory EU format does not have a separate “Added Sugars” line.
That makes the ingredient list and permitted nutrition claim especially useful. A drink can carry “with no added sugars” while showing measurable sugars in the nutrition declaration because the sugars were already present in its ingredients. These statements are not necessarily contradictory. The European Commission explains the presentation requirements in its nutrition-labeling guidance.
Why fruit juice concentrates need a closer look
Fruit juice contains sugars before processing. A recipe with no additional sucrose can therefore still have substantial sugar in the final juice drink. The sweet taste alone does not tell you whether sugar was added.
Concentrates raise another distinction. The FDA's industry Q&A describes circumstances in which certain juice concentrates are excluded from the Added Sugars declaration and others in which they contribute added sugars. The technical answer can depend on why and how a concentrate is used. “All concentrates count as added sugar” is too broad, but so is “concentrates never count.” Product teams need the formulation and destination-market rules to decide.
Does sugar-free mean no sweeteners?
No. Some drinks meet sugar-free conditions without added sweeteners. Others use permitted sweeteners to achieve a sweet taste while keeping sugar very low. A zero-sugar claim alone does not reveal which approach was used.
Read the ingredient list. The EU has additional labeling provisions for certain authorized sweeteners, including wording associated with the food's name. The European Commission's Sugars and Sweeteners overview, updated on 16 February 2026, also makes an important terminology distinction: “free sugars” as a research category is not the same as a “sugars-free” packaging claim. Similarly, sweetness is not a reliable measure of a drink's calorie count.
Four example labels, interpreted carefully
These are deliberately fictional teaching examples, not verified formulations or approved claims. The numbers use US-style grams per labeled serving. They show what an initial reading can establish, not whether a particular product is legally compliant.
The lesson is not that one formulation is universally better. It is that the same front-of-pack language can conceal important differences unless you inspect the complete label.
A five-step check before choosing a drink
- Read the exact claim. “No added sugar,” “zero sugar,” “unsweetened” and “low sugar” are not interchangeable.
- Find the sugar number. Check grams per serving on US packs and per 100 mL on EU packs. Normalize units when comparing.
- Look for Added Sugars where declared. Zero added does not mean zero total.
- Inspect ingredients. Check for sugars, sweetening ingredients, concentrates and non-sugar sweeteners. Their classification depends on context.
- Read calories and serving size. A single sugar claim does not describe the whole drink.
What beverage buyers and brands should verify
When developing a beverage for export, request a finished-product specification, the current ingredient formula, a verified nutrition panel and the exact proposed claim. Do not transfer wording from one flavor, bottle size or market to another without checking it. Confirm the destination country's rules before approving packaging artwork or web copy.
For marketing teams, consistency matters. If an approved label says “no added sugar,” a product description should not silently strengthen that to “sugar-free.” A manufacturer can discuss formulation options, but final claims must follow the actual finished beverage and the applicable regulations.
The bottom line
“No added sugar” describes ingredients and processing. “Sugar-free” describes a very low sugar level in the finished product under specific market rules. A beverage may satisfy the first description while containing enough naturally occurring sugar to fail the second. Read the claim, nutrition figures and ingredient list together. For commercial packaging, verify the recipe and current local requirements before treating either phrase as approved.
