Zero Added Sugar, Low Carb & High Fibre: What Do Food Labels Really Mean?
Not everything that looks healthy on the front of a packet tells the complete nutritional story. Learn how to decode common food-label claims and make smarter everyday choices.
Imagine standing in a supermarket, holding three different snack packs.
One says Zero Added Sugar. Another says Low Carb. The third proudly announces High Fibre.
All three sound healthy. But which one should you actually choose?
It is tempting to assume that any product with these words on its packaging must be good for you.
However, the truth is more interesting.
A zero-added-sugar food can still contain naturally occurring sugar.
A high-fibre snack can still contain significant calories.
And a low-carb product is not necessarily free from carbohydrates.
The secret to smarter shopping: Understand what food-label claims actually mean, what they don't tell you, and how to read the complete nutrition panel.
The 3 Claims You See Everywhere
These are some of the most common claims seen on protein bars, breakfast cereals, biscuits, snack foods and nutrition products.
Zero Added Sugar
Indicates that sugars have not been added under the applicable labelling conditions.
It does not automatically mean zero total sugar.
Low Carb
Describes the product's carbohydrate positioning. Check the actual amount and the serving size.
Low carb is not carbohydrate-free.
High Fibre
Indicates a substantial dietary fibre content under applicable nutrient-claim criteria.
Fibre is only one part of the nutrition profile.
Are You Buying the Claim or Understanding the Food?
The front of the packet catches your attention. The nutrition facts and ingredients help you make the decision.
1. What Does "Zero Added Sugar" Really Mean?
Zero added sugar, also referred to as no added sugar, means sugars have not been added during manufacture, subject to the relevant conditions for making that claim.
However, a food can still contain sugars naturally present in its ingredients.
For example, milk naturally contains lactose, a form of sugar.
Fruits naturally contain sugars too.
Therefore, a product may have some total sugar even when no additional sugar has been used.
Total Sugar vs Added Sugar
Refers to the total quantity of sugars present in the food, including naturally occurring and added sugars.
Refers to sugars added to the product during manufacturing, according to the applicable labelling definition.
Zero Added Sugar vs Sugar-Free
These are not interchangeable claims.
Under FSSAI's general nutrient-content-claim criteria, a product making a sugar-free claim must contain no more than 0.5 g sugars per 100 g or 100 ml.
A zero-added-sugar product may still contain naturally occurring sugars.
Shopping tip: Always check both total sugars and added sugars before selecting a packaged food based on its sugar claim.
2. What Does "Low Carb" Actually Mean?
Carbohydrates are an important source of energy in our daily diet.
Foods such as roti, rice, poha, idli, dosa, dal, fruit, milk and vegetables can all contribute carbohydrates.
Carbohydrates are not automatically bad.
The type, quantity and overall balance of your diet matter.
When a product says "low carb", don't automatically assume it has no carbohydrates.
Check the actual carbohydrate quantity and how the manufacturer is using the claim.
Total Carbs vs Net Carbs
Another term you may notice is net carbohydrates.
Some manufacturers calculate net carbs by subtracting dietary fibre from total carbohydrates.
Example Calculation
18 g Total Carbohydrates − 7 g Dietary Fibre = 11 g Net Carbs
This is an illustrative example, not the nutrition profile of a GreatVibes product.
The calculation and terminology used for net carbs may vary between manufacturers.
Always check how the brand defines its calculation.
Shopping tip: Compare the carbohydrate content per serving and per 100 g. Do not rely only on a front-pack low-carb claim.
3. What Does "High Fibre" Mean?
Dietary fibre is found in many plant foods.
Good sources include fruits, vegetables, whole grains, pulses, nuts and seeds.
Fibre supports normal digestive function. Fibre-rich foods may also contribute to fullness.
When Can a Product Claim to Be High in Fibre?
Under FSSAI's general criteria, a solid food can qualify as high or rich in fibre when it provides at least:
6 g Fibre
Per 100 g of solid food.
3 g Fibre
Per 100 kcal of food.
The regulations also specify criteria for liquids and may have additional product-category requirements.
High fibre is a meaningful nutritional characteristic, but it does not automatically mean the product is low in calories, carbohydrates or fat.
Simple rule: Fibre is useful, but evaluate the complete food rather than judging it by one nutrient.
Why One Food Label Claim Is Not Enough
Imagine comparing two packaged snacks.
One highlights zero added sugar. The other highlights high fibre.
Which one offers better everyday nutrition?
Let's compare two fictional examples.
| Nutrition Detail | Snack A | Snack B |
|---|---|---|
| Main Claim | Zero Added Sugar | High Fibre |
| Calories per pack | 240 kcal | 180 kcal |
| Protein | 4 g | 12 g |
| Fibre | 1 g | 8 g |
| Added Sugar | 0 g | 3 g |
Note: These are fictional products and illustrative nutrition values, not real brand comparisons.
Snack A has no added sugar, but relatively little protein and fibre.
Snack B has some added sugar, but provides more protein and fibre with fewer calories.
Which is the better choice depends on your needs, portion size and overall diet.
Key takeaway: A single food-label claim is not enough to determine the overall nutritional quality of a product.
The 30-Second Food Label Reading Method
The next time you pick up a protein bar, cereal, biscuit or packaged snack, check these five things.
Check Serving Size
Are the nutrition values listed per 25 g, 50 g, 100 g or per complete pack?
Look at Calories
Check the energy provided by the portion you actually intend to eat.
Check Sugar Values
Compare total sugars and added sugars. These are not the same thing.
Check Protein, Carbs and Fibre
Consider whether the nutritional profile matches the purpose of your snack.
Read Ingredients and Allergens
Identify protein sources, nuts, seeds, sweeteners and ingredients you need to avoid.
The Smart Shopper Rule
Read the front for the claim. Turn the pack around for the complete facts.
Understanding a Real Nutrition Label: GreatVibes Nuts & Seeds Protein Bar
Let's apply the same label-reading method to a real product.
GreatVibes Nuts & Seeds Protein Bar combines nuts, seeds, soy-based protein ingredients and dietary fibre.
The GreatVibes product information provides the following values for a serving of two 25 g bars (50 g total).
The brand also lists 6.5 g net carbohydrates per two-bar serving according to its stated calculation.
Here is the important label-reading lesson: These quantities apply to two bars, not one.
If you eat one 25 g bar, you should use its corresponding nutrition values rather than assuming you consumed the entire two-bar serving.
Don't Forget the Ingredients
The product ingredients include nuts and seeds, soy-based protein ingredients and a no-added-sugar dark compound containing maltitol.
Maltitol is a sugar alcohol used for sweetness. Certain sugar alcohols may cause digestive discomfort or a laxative effect in some people, particularly with larger intakes.
This is why the ingredient list and any relevant warning statements are also worth reading.
The product information identifies nut, soy and milk-related allergen considerations. Always check the latest physical pack if you have allergies.
The goal isn't to choose a snack because of one attractive claim. It is to make an informed choice using the complete label.

5 Common Food Label Mistakes to Avoid
1. Confusing Zero Added Sugar with Sugar-Free
Naturally occurring sugars may still contribute to the total sugar content.
2. Assuming High Fibre Means Unlimited Portions
Fibre is useful, but the quantity you consume and the total calories still matter.
3. Assuming Low Carb Means No Carbs
Check the numerical carbohydrate content, serving size and the manufacturer's definition.
4. Ignoring Serving Size
Nutrition information for one serving may not represent the quantity in the complete pack.
5. Never Reading the Ingredients
Ingredients and allergen warnings can provide important information beyond the front claim.
Does Zero Added Sugar Automatically Mean Diabetes-Friendly?
Not necessarily.
Food products with zero added sugar can still contain carbohydrates and calories.
Both the total amount of carbohydrate and the portion consumed can matter for blood glucose management.
If you have diabetes, evaluate the complete food composition and follow individual dietary advice from your healthcare professional.
Remember: No single label claim establishes that a food is suitable for every person or medical condition.
Quick Quiz: How Well Can You Read a Food Label?
Test yourself with these three simple questions. Tap each question to reveal the answer.
1. Can a zero-added-sugar product still contain sugars?
Yes. Naturally occurring sugars may still be present in the ingredients.
2. A snack contains 100 calories per serving and has three servings. How many calories are in the pack?
300 calories. Always multiply the per-serving values by the quantity consumed.
3. Does a high-fibre claim tell you the protein quantity?
No. Fibre and protein are separate nutrients. Check their values independently.
Your Smart Food Shopping Checklist
The next time you visit a supermarket or browse snacks online, use this simple checklist.
- Check the serving size.
- Look at calories per serving.
- Compare total sugars and added sugars.
- Check total carbohydrates.
- Look at protein and dietary fibre.
- Read the ingredient list carefully.
- Check allergens and other warning statements.
- Compare similar products using consistent serving sizes or per-100-g values.
Final Thoughts: Don't Just Read the Big Words. Read the Small Numbers.
Zero Added Sugar, Low Carb and High Fibre can all communicate useful information.
But none of these claims tells you everything about the food.
The smarter approach is to look beyond attractive packaging and understand what each serving actually provides.
Consider calories, protein, fibre, carbohydrates, sugars, ingredients and serving size together.
Whether you're buying breakfast cereals, everyday snacks, protein bars or protein supplements, these habits can help you make more informed choices.
A Better Food Choice Starts with a Better Understanding of the Label.
Read the headline. Then read the numbers.
