Front-of-pack claims like “fat-free” or “no added sugar” are marketing, not nutrition facts; the ingredients list and nutrition panel on the back tell the real story. Under FSSAI’s Labelling and Display Regulations 2020, ingredients must appear in descending order by weight, so if sugar or one of its many aliases sits in the first three, the product is sugar-heavy regardless of the front label.

Why Can Front-of-Pack Claims Be Misleading?
Words like “fat-free,” “all natural,” “no added sugar” or “sugar-free” on the front of a package are marketing copy, not a nutrition summary. They are legally regulated to some degree, but they are selected to make you feel good about the purchase, not to give you the full picture. The nutrition information panel and ingredients list on the back are where the actual composition of the product lives, and that is where label-reading should start.
How Are Ingredients Listed on Indian Food Labels?
Under FSSAI’s Food Safety and Standards (Labelling and Display) Regulations, 2020, ingredients must be listed in descending order of their composition by weight or volume at the time of manufacture. That means whatever appears first is present in the largest quantity. If sugar, or one of its many aliases, shows up in the first three ingredients, the product is functionally a sugar-forward food no matter what the front label claims. Compound ingredients that make up more than 5% of the product must also have their own components broken out.
What Must Every Indian Food Label Legally Include?
Beyond the ingredients list, FSSAI’s Labelling and Display Regulations, 2020 make several declarations mandatory on every packaged food sold in India, regardless of brand or category. Checking for these is a quick way to confirm you are looking at a compliant label in the first place.
| Mandatory element | What to look for |
|---|---|
| Veg/non-veg symbol | A green dot for vegetarian, a brown dot for non-vegetarian, displayed prominently near the product name |
| FSSAI licence number | A 14-digit number, usually printed near the FSSAI logo |
| Batch or lot number | Used for traceability if there is ever a recall or quality issue |
| Best before or use-by date | Month and year for products with a shelf life over 3 months; full day, month and year for shorter shelf life |
| Net quantity | The actual weight or volume in the pack, separate from any serving size claims |
What Do Common Front-of-Pack Claims Actually Require?
Nutrient content claims are not just marketing flourishes; FSSAI’s Food Safety and Standards (Advertising and Claims) Regulations, 2018 set specific thresholds a product must meet before printing them, under Schedule I. Knowing the actual definition behind a claim tells you what it does and does not promise.
| Claim | What it actually requires | What it does not tell you |
|---|---|---|
| “Fat-free” | No more than 0.5 g fat per 100 g (solids) or 100 ml (liquids) | Says nothing about sugar or total calories, which are often higher to compensate for taste |
| “Sugar-free” | No more than 0.5 g sugar per 100 g or 100 ml | Does not guarantee the product has no sweeteners or is low-calorie |
| “No added sugar” | No sugar or sugar-equivalent ingredient was added during manufacturing | Does not mean low in sugar; naturally occurring sugars (from fruit, milk) can still be present and must be declared |
| “High protein” / “source of protein” | Minimum protein content tied to a defined share of the Recommended Dietary Allowance under Schedule I | Does not speak to protein quality or whether other ingredients offset the benefit |
What Are the Different Names for Added Sugar?
Manufacturers often split sugar across several ingredient names so no single one dominates the list, even when the combined sugar content is high. Recognising these names is the single most useful label-reading skill for spotting hidden sugar.
| Common name on Indian labels | What it actually is |
|---|---|
| Maltose, dextrose, fructose | Simple sugars, nutritionally equivalent to table sugar |
| High-fructose corn syrup, glucose syrup | Processed sugar syrups, common in packaged sauces and drinks |
| Maltodextrin | A carbohydrate filler common in protein powders; not always labelled as “sugar” but digests quickly like one |
| Agave nectar, jaggery powder, cane juice crystals | Marketed as natural alternatives, but nutritionally still added sugar |
| Fruit juice concentrate | Often contributes more sugar per serving than the fruit it is derived from |
If you spot two or three of these names spread across one ingredient list, treat it as a single, larger sugar entry rather than several small ones, since that is functionally what it is.
How Much Added Sugar Is Too Much?
The World Health Organization’s 2015 sugars guideline recommends limiting free sugars, which includes all added sugar plus sugars naturally present in honey, syrups and fruit juice, to under 10% of total daily energy, with a further reduction to under 5% offering additional benefit. For a 2,000 kcal diet, 10% works out to about 50 g of free sugar a day, roughly 12 teaspoons, and 5% is about 25 g. Indian dietary guidelines from ICMR-NIN broadly track this WHO framework rather than setting a separate, higher national limit.
Why Does Serving Size Matter More Than Calories Per Pack?
A snack advertising “50 calories per serving” sounds modest until you check what one serving actually is; if the pack contains five servings and you realistically eat the whole thing in one sitting, the true intake is five times the number on the front. FSSAI’s labelling rules require declaring both the serving size and the number of servings per pack, along with nutrition values per 100 g or 100 ml, which is the number to compare across products rather than the per-serving figure alone. Comparing per-100g values is the most reliable way to judge two competing products fairly, since serving sizes are not standardised between brands.
What Does the Nutrition Information Panel Actually Tell You?
The nutrition panel lists energy, protein, total carbohydrate (with added sugar broken out separately under recent FSSAI amendments), total fat (with saturated fat and trans fat broken out), and sodium, generally per 100 g/ml and per serving. This is the section that lets you verify a front-of-pack claim: a product can legitimately say “no added sugar” while still being high in total carbohydrate or fat, so treat any single claim as one data point, not the full nutritional verdict.
A worked example makes this concrete. Suppose a 150 g pack of biscuits lists 480 kcal, 18 g fat, 62 g total carbohydrate and 22 g of it as sugar, per 100 g. The pack itself, being 150 g, actually contains 720 kcal, 27 g fat and 33 g sugar if eaten entirely, which is roughly 66% of the WHO 10% free-sugar ceiling for an average adult in a single sitting. None of that is visible from a front label promising “made with real fruit” or “no artificial colours.” The 100 g figures are what let you do this arithmetic for yourself, and it takes under a minute once you know which three numbers to multiply.
How Strong Is the Evidence Linking Added Sugar to Health Harm?
Not every commonly repeated claim about sugar carries the same strength of evidence. The table below separates what large human studies support from what is more preliminary or mechanism-based.
| Claim | Best available evidence | Tested in humans? | How settled |
|---|---|---|---|
| Higher added sugar intake raises cardiovascular mortality risk | Yang et al. 2014, JAMA Internal Medicine: large US cohort found CVD mortality risk rose as the share of calories from added sugar rose, with about 10% of US adults getting 25% or more of calories from added sugar, well above the WHO limit | Yes, large prospective cohort | Well established directionally; exact risk magnitude varies by study |
| Excess sugar raises triglycerides and drives insulin resistance | Consistently shown in controlled feeding studies and supports WHO’s 2015 guideline | Yes | Well established |
| Sugar causes tooth decay | Long-established dose-response relationship between free sugar intake and dental caries | Yes, extensive epidemiology | Well established |
| Sugar directly causes mood swings, anxiety or depression | Some observational links exist, but the mechanism is not well isolated from confounding diet and lifestyle factors | Mixed, mostly observational | Not well established as a direct causal claim |
What Should You Check First When Reading a Label?
A practical, repeatable order of checks turns label-reading from a chore into a 20-second habit.
| Step | What to look at | Why it matters |
|---|---|---|
| 1 | Ingredients list, first three items | Listed by descending weight; sugar or its aliases here means a sugar-forward product |
| 2 | Number of sugar aliases across the whole list | Split naming hides total sugar load |
| 3 | Serving size and servings per pack | Front-of-pack calorie or sugar claims are only valid per stated serving, not per pack |
| 4 | Values per 100g/100ml on the nutrition panel | The only consistent basis for comparing two different products |
| 5 | Added sugar and trans fat lines specifically | These carry the clearest links to diet-related disease risk |
The Bottom Line
Reading a food label well takes about 20 seconds once you know where to look: ingredients in descending order by weight, watch for sugar’s many aliases, check the serving size against what you would realistically eat, and compare per-100g nutrition values rather than trusting the front-of-pack claim alone. None of this requires special training, only knowing what FSSAI’s labelling rules already guarantee you access to.

Frequently Asked Questions
What are some hidden names for sugar on food labels?
Common aliases include maltose, dextrose, fructose, high-fructose corn syrup, glucose syrup, maltodextrin, agave nectar, jaggery powder, cane juice crystals and fruit juice concentrate. Manufacturers sometimes split sugar across two or three of these names so no single ingredient dominates the list, even when combined sugar content is high.
How much added sugar is safe to eat per day?
WHO's 2015 guideline recommends keeping free sugars under 10% of total daily energy, with additional benefit below 5%. For a 2,000 kcal diet, that is roughly 50 g (about 12 teaspoons) at the 10% mark and about 25 g at the 5% mark. Indian dietary guidance broadly follows this WHO framework.
Does 'no added sugar' mean a product is low in sugar?
No. Under FSSAI's Advertising and Claims Regulations 2018, 'no added sugar' only means no sugar or sugar-equivalent ingredient was added during manufacturing. The product can still contain naturally occurring sugars from ingredients like fruit or milk, and these must be declared on the nutrition panel.
Why should I check the nutrition panel per 100g instead of per serving?
Serving sizes are not standardised between brands, so a per-serving claim on one product cannot be fairly compared to another. Values per 100g or 100ml give a consistent basis for comparison and let you calculate the actual nutrition in the amount you plan to eat, rather than the amount the label assumes.
What must every packaged food label in India legally show?
FSSAI's Labelling and Display Regulations 2020 require the food name, full ingredients list, nutrition information, a veg (green dot) or non-veg (brown dot) symbol, the FSSAI logo and 14-digit licence number, net quantity, batch number, and a best-before or use-by date.
Is sugar-free the same as fat-free in terms of the rules?
Both are nutrient content claims with defined thresholds under FSSAI's Advertising and Claims Regulations 2018: fat-free requires no more than 0.5g fat per 100g or 100ml, and sugar-free requires no more than 0.5g sugar per 100g or 100ml. Neither claim says anything about the other nutrient or about total calories.
