Why Nutrition Labels Matter
Every packaged food product carries a nutrition label, yet most of us glance at it without really knowing what to look for. Learning to read these labels gives you genuine insight into what you're putting in your body — without relying on front-of-package marketing claims like "natural," "light," or "wholesome."
Start With the Serving Size
This is the most overlooked part of the label and often the most important. All the nutritional information listed applies to one serving, not the entire package. If a bag of chips lists 150 calories per serving but contains three servings, eating the whole bag means consuming 450 calories.
Always check: How many servings are in this container? How much of this will I realistically eat?
Calories: Context Over Number
Calories matter, but they're not the whole story. A 200-calorie serving of almonds and a 200-calorie serving of a sugary snack cake have very different effects on satiety, blood sugar, and nutrition. Use calories as a reference point, not the sole deciding factor.
Macronutrients: What to Look For
Fats
- Unsaturated fats (monounsaturated, polyunsaturated): Generally beneficial — found in nuts, avocados, fish
- Saturated fats: Fine in moderation; most guidelines suggest keeping these limited
- Trans fats: Avoid these where possible — look for "partially hydrogenated oils" in the ingredients list as a flag
Carbohydrates
- Total carbs include sugars and fibre
- Dietary fibre: You want more of this — it supports digestion and helps you feel full
- Total sugars vs. added sugars: Added sugars are the ones to watch. Some sugar from whole foods like fruit or milk is fine; added sugars in processed foods are worth limiting
Protein
Protein supports muscle maintenance, satiety, and metabolic function. Check this number especially if you're active or managing your weight. Most adults benefit from prioritising protein at each meal.
The % Daily Value Column
The %DV column tells you what percentage of a daily reference intake one serving provides. Use this as a rough guide:
| %DV | What It Means |
|---|---|
| 5% or less | Low in this nutrient |
| 15–20% or more | High in this nutrient |
Aim for high %DV for fibre, vitamins, and minerals. Aim for low %DV for saturated fat, sodium, and added sugars.
Sodium: The Hidden Culprit
Sodium is one of the most common hidden ingredients in processed and packaged foods — even sweet ones. Many products marketed as healthy contain surprisingly high levels. A general guideline is to aim for foods with less than 600mg sodium per serving for main meals, and less than 200mg for snacks.
The Ingredients List
Ingredients are listed in order of quantity — from most to least. A quick scan tells you a lot:
- If sugar (or one of its many aliases: cane syrup, dextrose, fructose, maltose) appears in the first three ingredients, it's a high-sugar product
- A shorter ingredients list generally means less processing
- Ingredients you can't pronounce aren't automatically harmful, but an abundance of them is worth noting
Front-of-Package Claims: Be Sceptical
Terms like "reduced fat," "multigrain," "low calorie," and "natural" are marketing language, not nutritional judgements. A "low fat" biscuit may be high in sugar to compensate for flavour. Always turn the package over and read the actual label.
Putting It All Together
You don't need to scrutinise every label at every meal — that becomes obsessive and unsustainable. The goal is to build enough literacy that you can make quick, informed choices and spot products that don't deliver on their promises. Start by checking the serving size, added sugars, and ingredients list. That alone will dramatically improve your food decision-making.
