The Ingredients List: Reading the Fine Print

Ages 10–14 25 min read Intermediate

The ingredients list is the most honest part of any food package. By law, it must list every ingredient in descending order by weight. The first ingredient is what the product is mostly made of. If sugar is first — you're eating sugar with flavourings.

Rules of the Ingredients List

1. Order = Weight

Ingredients are listed from most to least by weight. If "sugar" appears in the first three ingredients, sugar is a major component of the product. If "chicken" is the first ingredient in chicken nuggets, you're off to a good start. If "wheat flour" is first, you're eating mostly batter.

2. Numbers Are Additives

Numbers in brackets (e.g., "colour (102)", "preservative (220)") are food additives approved by FSANZ. There are over 300 approved food additives in Australia. Most are safe; some are controversial.

Common ones to know:

  • E621 / MSG: Flavour enhancer. Safe for most people despite its bad reputation.
  • E211 / Sodium Benzoate: Preservative. Can react with vitamin C to form benzene (a carcinogen) in some conditions.
  • E102 / Tartrazine: Yellow colour. Linked to hyperactivity in some children.
  • E951 / Aspartame: Artificial sweetener. Extensively studied; considered safe by FSANZ and WHO at normal consumption levels.

3. The Compound Ingredient Trick

If a product contains "chocolate (45%)", the chocolate's own ingredients are listed in brackets. This can make it hard to tell total sugar content because sugar appears in multiple compound ingredients.

4. Allergen Bolding

Australian law requires major allergens to be declared in bold or CAPITALS: milk, eggs, peanuts, tree nuts, fish, shellfish, soy, wheat (gluten), lupin, sesame.

The Short List Rule

A simple guide to healthier choices: the shorter the ingredients list, the less processed the product. An apple has one ingredient. A muesli bar might have 30. Neither is inherently bad, but the shorter list usually means less processed.

Tonight's Question

"Pick the most processed product in our pantry. Read the ingredients list out loud. How many ingredients does it have? Can you identify them all?"

Ingredient Detective

  1. Pick 5 products from your pantry.
  2. Count the ingredients in each.
  3. Highlight any ingredients you can't pronounce or don't recognise.
  4. Look them up: what are they? Why are they there?
  5. For each product, ask: could we make a simpler version at home?
  6. Try it: make a simple version of one product (e.g., homemade muesli vs bought muesli bars).

What We Simplified

  • Long ingredient lists aren't automatically bad. A complex spice blend has many ingredients but can be perfectly healthy.
  • Most food additives are safe. The approval process is rigorous. Fear of "chemicals" is often unwarranted — water is a chemical too.
  • "Natural" doesn't mean additive-free. Many additives (like citric acid, lecithin) are derived from natural sources.
