How to Read Nutrition Labels: A Beginner’s Guide to Making Informed Food Choices

Introduction

Walking through a supermarket can sometimes feel overwhelming.

Many food packages display claims such as “low fat,” “high protein,” “natural,” “whole grain” or “no added sugar.” While these labels can be useful, they don’t always tell the full story about a food’s nutritional value.

This is where the Nutrition Facts label and ingredient list become valuable tools.

Learning how to read nutrition labels can help you better understand what’s in the foods you buy. Rather than relying on marketing claims, nutrition labels provide factual information about serving sizes, calories, nutrients and ingredients.

It’s important to remember that nutrition labels are designed to inform—not to encourage perfection. You don’t need to analyse every product or avoid foods simply because they contain sugar, fat or sodium. Instead, nutrition labels help you compare similar products and make choices that align with your overall eating pattern.

At 1% Movement, we believe healthy eating should be practical and evidence-based. Understanding nutrition labels is a useful skill that can help you build healthier habits without making grocery shopping stressful.

In this article, you’ll learn how to read nutrition labels, what the different sections mean and how to use them when making everyday food choices.

What Is a Nutrition Label?

A nutrition label is a standardised panel found on packaged foods that provides information about the nutritional content of the product.

Although label formats vary slightly between countries, they typically include information such as:

  • Serving size 
  • Calories or energy 
  • Carbohydrates
  • Protein
  • Fat 
  • Fibre 
  • Sugars
  • Sodium
  • Vitamins and minerals (on some products) 

The label allows you to compare similar foods more easily and understand how a particular product fits into your overall diet.

Nutrition labels are intended to provide objective information, while the claims printed on the front of packaging are primarily used for marketing.

Start with the Serving Size

The first thing to check on any nutrition label is the serving size.

The serving size tells you the amount of food that all the nutritional information on the label is based on.

For example, a packet of crackers may list:

  • Serving size: 30 g 
  • Servings per package: 4 

If you eat the entire packet instead of one serving, you will consume approximately four times the amounts shown on the label.

This is why serving size is important—it helps you correctly interpret the rest of the nutrition information.

Remember that a serving size is not a recommendation for how much you should eat. It is simply a standard reference amount used to present nutritional information.

Understanding Calories (Energy)

Nutrition labels usually display the amount of energy provided by one serving.

Depending on your country, this may be shown as:

  • Calories (kcal) 
  • Kilojoules (kJ) 
  • Both 

Calories represent the amount of energy the food provides.

However, calories alone do not tell you whether a food is nutritious.

For example:

  • A handful of almonds contains more calories than many sugary snacks. 
  • However, almonds also provide healthy fats, fibre, protein and important minerals. 

Rather than focusing only on calories, consider the overall nutritional quality of the food.

Understanding the Macronutrients

Nutrition labels also show the amounts of the three macronutrients.

Carbohydrates

This section shows the total amount of carbohydrates in one serving.

Some labels also separate:

  • Dietary fibre 
  • Total sugars 
  • Added sugars (where required) 

Remember that carbohydrates include both naturally occurring carbohydrates found in foods such as fruit and milk, as well as carbohydrates from grains and added sugars.

Our article Carbohydrates Explained explores this topic in more detail.

Protein

The protein section shows how much protein one serving provides.

Protein contributes to muscle maintenance, tissue repair and many other important body functions.

Comparing protein content can be useful when choosing between similar products, particularly foods such as yoghurt, breakfast cereals or snack options.

You’ll learn more in our article Protein Explained.

Fat

Nutrition labels usually list:

  • Total fat 
  • Saturated fat 

Some labels may also include trans fat.

Rather than avoiding fat completely, remember that healthy fats are an important part of a balanced diet.

Our article Healthy Fats Explained explains the different types of dietary fat and their roles in supporting health.

Understanding Fibre, Sugars and Sodium

In addition to carbohydrates, protein and fat, nutrition labels often include information about fibre, sugars and sodium.

Understanding these sections can help you make more informed food choices.

Fibre

Fibre is an important part of a healthy diet.

Foods higher in fibre may help support:

  • Digestive health. 
  • Heart health. 
  • Feelings of fullness after meals. 

When comparing similar products, choosing the option with more fibre can often be beneficial.

To learn more, read our article Fibre Explained.

Sugars

Many nutrition labels list:

  • Total sugars 
  • Added sugars (in some countries) 

It’s important to understand the difference.

Total sugars include both:

  • Naturally occurring sugars (such as those found in fruit and milk) 
  • Added sugars used during food manufacturing 

Foods containing naturally occurring sugars can still be highly nutritious.

Rather than avoiding all sugar, consider the overall nutritional quality of the food.

Sodium

Sodium is a mineral that helps regulate fluid balance and supports normal nerve and muscle function.

However, many packaged and highly processed foods contain relatively large amounts of sodium.

Comparing similar products may help you choose options with lower sodium while still enjoying a balanced diet.

Why the Ingredient List Matters

The nutrition label tells you how much of each nutrient a food contains.

The ingredient list tells you what the food is made from.

Ingredients are listed in descending order by weight.

This means the ingredient listed first is present in the greatest amount.

For example, if sugar appears near the beginning of the ingredient list, it indicates that sugar makes up a relatively large proportion of the product.

Looking at both the nutrition label and the ingredient list provides a more complete understanding of the food.

Don’t Judge Food by One Number

One of the biggest mistakes people make is focusing on a single number.

For example:

  • Choosing foods based only on calories. 
  • Avoiding foods because they contain fat. 
  • Buying products simply because they’re high in protein. 

Healthy eating is about considering the whole food, not one nutrient.

Ask yourself questions such as:

  • Does this food provide fibre? 
  • Does it contain protein? 
  • Is it made mostly from whole or minimally processed ingredients? 
  • How does it fit into my overall eating pattern? 

These questions are often more useful than focusing on one nutrition claim.

Common Nutrition Label Myths

Reading nutrition labels becomes easier once you understand a few common misconceptions.

Myth 1: Low-fat always means healthier.

Not necessarily.

Some low-fat products contain added sugar or extra ingredients to improve flavour.

Looking at the entire nutrition label gives a more complete picture.

Myth 2: More protein automatically means healthier.

No.

Protein is important, but healthy foods also provide carbohydrates, healthy fats, fibre, vitamins and minerals.

Nutrition is about overall balance rather than maximising one nutrient.

Myth 3: Foods with long ingredient lists are always unhealthy.

Not always.

Some nutritious foods naturally require multiple ingredients, particularly frozen meals, soups or fortified products.

Instead of counting ingredients, consider the types of ingredients listed and the overall nutritional quality of the food.

Myth 4: You need to memorise every nutrient.

No.

Most people don’t need to analyse every number on every label.

Understanding the basics—serving size, calories, protein, fibre, sugars, sodium and the ingredient list—is usually enough to make more informed decisions.

Frequently Asked Questions

Why should I read nutrition labels?

Nutrition labels help you understand what’s in packaged foods and make it easier to compare similar products.

They provide factual information rather than marketing claims.

What should I look at first?

Start with the serving size.

All of the nutrition information on the label is based on this amount.

Are calories the most important part of the label?

No.

Calories provide information about energy, but they don’t tell you the overall nutritional quality of a food.

It’s helpful to consider calories alongside fibre, protein, healthy fats and the ingredient list.

Should I avoid foods with sugar?

Not necessarily.

Many nutritious foods, such as fruit and milk, naturally contain sugar.

Instead of avoiding all sugar, focus on your overall eating pattern and choose foods with fewer added sugars more often.

Why is the ingredient list useful?

The ingredient list shows what a food is made from and the order of ingredients by weight.

Reading it alongside the nutrition label provides a better understanding of the product.
