Did you know that “no added sugar” on a fruit drink does not mean “sugar-free”? These two phrases look like close relatives, but they answer different questions. When a child sees them on a carton, the important skill is not memorising which sounds healthiest—it is reading the claim, the nutrition panel and the serving size together.
No added sugar refers to whether sugars were added during processing, not whether the final drink contains naturally occurring sugars. A sugar-free claim concerns a very low amount of sugars in the final product under the applicable labelling criteria; Singapore’s Health Promotion Board describes a sugar-free Healthier Choice Symbol tagline as at most 0.5 g of sugars per 100 g or 100 ml. Unsweetened generally describes a product made without added sweeteners, but the precise claim should be checked in its market and product context. None of these phrases should replace reading the actual numbers.
The supermarket thought experiment
Imagine a parent and Primary 5 student choosing a drink to take on a picnic. Carton A says “no added sugar” and gives 10 g of total sugars per 100 ml on its nutrition panel. Bottle B carries a qualifying “sugar-free” claim and states 0.3 g of sugars per 100 ml. Bottle C says “unsweetened tea” and reports 0 g of total sugars per 100 ml. These are invented teaching labels, not real products, nutritional recommendations or evidence of a brand’s contents.
The labels do not contradict one another. Carton A can contain sugar naturally present in its ingredients, even if none was added. Bottle B contains a small stated amount. Bottle C indicates an unsweetened formulation; the nutrition panel provides the numerical check. The reading task is to identify which claim talks about manufacture and which talks about composition.
Work out what the label actually says
A typical label often gives amounts per 100 ml. If fictional Carton A contains 10 g of total sugars per 100 ml and the child drinks 250 ml, the arithmetic is 10 × 2.5 = 25 g of total sugars. For fictional Bottle B at 0.3 g per 100 ml, 250 ml contains 0.3 × 2.5 = 0.75 g. The difference is visible only when you combine vocabulary with volume and multiplication.
A frequent error is to read a large front-of-pack phrase and skip the unit. Another is to compare a 200 ml bottle directly with a 500 ml bottle using their per-container amounts instead of a common basis. Per 100 ml standardises the comparison; per serving may refer to a different quantity decided for the product. Ask what is being compared before declaring one number smaller.
Word families and distinctions that matter
- Add / added / addition: identify something introduced during manufacture. “No added sugar” is not a synonym for “zero sugar”.
- Natural / naturally occurring: present in the ingredients without being separately added. Natural does not automatically mean nutritionally unlimited.
- Sweet / sweeten / sweetener: distinguish the taste from the ingredients used to create that taste. A drink may taste sweet for different reasons.
- Concentration: an amount relative to a volume, as in “grams per 100 ml”. This is a Science and Mathematics idea as well as a reading skill.
- Serving: the amount represented by one stated portion; container: the whole pack; the two may not be equal.
- Claim: what the pack asserts; evidence: what the ingredient list and nutrition panel allow you to verify.
What Singapore’s Nutri-Grade adds to the picture
Singapore’s Nutri-Grade system evaluates beverages using sugar and saturated fat criteria. HealthHub explains that a drink may be graded less favourably even when it has relatively little sugar, if its saturated fat level is higher; a drink containing naturally occurring fruit sugars may also receive a C or D grade despite a “no added sugar” claim. Nutri-Grade C and D drinks are required to display the grade, while A and B labelling is optional in the circumstances described by HealthHub.
The lesson is about reading several measures together. A grade is not a new synonym for the sugar claim on the front of the bottle, and one label should not be used to infer everything about the product. Water is a straightforward default drink; people with specific dietary needs should follow appropriate qualified advice rather than drawing medical conclusions from this vocabulary exercise.
A five-minute family detective exercise
At home, collect photos of two or three genuine drink labels without assuming one must be better. Ask the student to identify each unit and highlight any phrase that starts with no, free, less or unsweetened. Then make three columns: exact words, numerical sugar per 100 ml, and one thing the label does not tell you. This last column teaches restraint.
- Question 1: Is “less sugar” the same as “sugar-free”? No. “Less” is a comparison; “free” is a claim about a very low final amount under relevant criteria.
- Question 2: What could a child reasonably say about 100% fruit juice marked “no added sugar”? “It may still contain sugars naturally present in the juice; I should check the nutrition panel.”
- Question 3: What extra information makes a fair comparison? The same unit, the volume consumed, the total sugars figure, and relevant other nutritional information.
- Question 4: Can you rewrite a vague sentence? Change “This carton has no sugar” to “The pack says no sugar was added, but the nutrition panel shows 10 g total sugars per 100 ml.”
From English comprehension to Science and adulthood
A PSLE-age learner practises spotting the scope of a phrase: “no added sugar” is not the same as “no sugar”. In secondary Science, students can connect concentration to units and sources of substances. In Mathematics, they scale per-100-ml quantities accurately. Adults use the same reading discipline when comparing product descriptions, interpreting advertisements and asking precise questions in shops.

Frequently asked questions
Does “no added sugar” necessarily mean low-calorie? No. HealthHub explicitly warns that a product with no added sugar may still contain naturally occurring sugars and does not necessarily contain fewer calories.
Does “sugar-free” automatically mean unsweetened? No. A product can meet a low-sugars threshold and still taste sweet because of sweetening substances. Product-specific ingredients and applicable labelling rules matter.
Should I use only the front of the pack? No. Read the nutrition information panel, amount per 100 ml, serving size and ingredient list together. For personalised dietary or medical decisions, seek qualified guidance.
The useful vocabulary habit is to ask: “What exactly does this word rule in—and what does it leave open?” A few seconds of precise reading can turn an attractive claim into an informed question.
