How to read food labels and why it’s a skill worth building

Learning to read ingredient lists and nutrition panels is one of the most practical, empowering skills you can develop. It allows you to move from reacting to marketing to making informed choices based on what’s actually in the product. It helps you to understand what you’re actually eating so you can make intentional decisions that align with your health goals.
Most packaged foods look similar from the front of the packet. The marketing language is polished, the claims are appealing, and it’s easy to assume two products are broadly comparable. Often, they’re not.
Why reading food labels is so important
When you understand a food label, you’re able to:
See how processed a product is
Identify added sugars, excess sodium, or unnecessary additives
Assess whether the product meaningfully contributes protein or fibre
Compare similar products objectively
Decide whether the ingredients align with your personal values or goals
You don't need to label foods as “good” or “bad”. But when you know what a product actually contains, you can then make an informed decision about whether it's right for you and your family.
Step 1: Start with the ingredient list
Ingredients are listed in descending order by weight. The first few ingredients make up the majority of the product. When reading the ingredient list, consider:
➡️ How many ingredients are there?
A shorter ingredient list often suggests less processing, though this isn’t a strict rule. The goal isn’t minimalism for its own sake, just to understand what's in there.
➡️ Do you recognise what they are?
If you can’t identify an ingredient, it doesn’t automatically make it harmful. But it’s reasonable to pause and ask what it is and what role it plays. Preservative? Emulsifier? Flavour enhancer? If you’re unsure, you can look it up or use an ingredient-checking app to understand what it does.
➡️ How many additive numbers are included?
In Australia, additives are often listed as numbers (for example, 621 or 471). Some are harmless stabilisers, others are flavour enhancers or preservatives. The key question isn’t whether any number is present, but how many, what they are and whether you’re comfortable with that level of processing. Again, this is about informed choice.
Step 2: Then look at the nutrition information panel
Once you’ve reviewed the ingredient list, move to the nutrition panel.
The most important rule here is: Compare products per 100g, not per serve.
Serving sizes are determined by the manufacturer and vary widely between brands. One cereal might list 30g as a serving, while another lists 45g. Comparing per serve can make products look artificially better or worse, simply because the serving size is different. Per 100g allows for more objective comparison. Here are the main things to assess:
⭐️ Protein
Does the product meaningfully contribute to your daily protein intake? For example, a yoghurt with 10g of protein per 100g is very different from one with 3g.
⭐️ Fibre
Fibre is often lacking in packaged foods. Products containing 3g or more per serve (and ideally much higher per 100g) contribute more meaningfully to gut and metabolic health.
⭐️ Sugars
Look at total sugars per 100g and consider the ingredient list. If sugar, syrup, honey, or fruit concentrate appears in the first few ingredients, the product is likely more sugar-dense. Remember, 5g of sugar is 1 teaspoon.
⭐️ Fat
Rather than fearing fat, look at the type of fat and the overall context of the product. Nuts and yoghurt will naturally contain fat; confectionery will combine fat and sugar in a very different way.
⭐️ Sodium
Many savoury packaged foods are high in sodium. Comparing per 100g helps you see which option is genuinely lower.
Pay attention to serving size
After comparing per 100g, look at what the manufacturer defines as one serve. Often, it’s smaller than what most people would realistically eat. For example, if a muesli bar lists 18g as a serving but the whole bar is 35g, that information can change your interpretation of a food and it's place in your diet.
This gets easier with practice
The first time you consciously read labels, it can feel slow and overwhelming. Shopping may take a bit longer than usual. That's ok. It gets easier and much faster over time.
If you make a habit of checking labels, you'll notice patterns emerge. You’ll begin to recognise brands that tend to use fewer additives or offer higher protein and fibre options. You’ll stop needing to check certain products because you already know how they compare.
If you’re just getting started, I recommend you choose five products you buy every week and read only those labels next time you go to the supermarket. Compare similar product options available and make a decision about which one is best for you and your family. Then, next time you shop, you can choose another 5 products and compare those labels.
Over a few weeks, you build label literacy without turning your grocery shop into a two-hour research session.
Information is empowerment
Reading food labels is all about building awareness of the foods you eat everyday. When you understand what you’re buying, you’re no longer relying on front-of-pack claims or clever marketing. You’re making intentional choices based on real information. That’s a skill that compounds over time, and it supports your health in a practical, sustainable way.
