Health Star Ratings – A Guide

You may have noticed a new star rating logo on some of your favourite grocery items in the supermarket? Wondering what it’s all about?

This is a voluntary front of pack health rating system that is funded by state and Federal Governments to highlight healthier food options to consumers, in an attempt to reduce overweight and obesity in Australia.

The idea behind the star rating is to highlight positive and at risk nutrients within a particular food.

How does it work?

Foods deemed to be healthy by the rating system will receive 5 stars as the highest rating, with 0.5 stars being the lowest rating. The following nutrients are considered when allocating points:


The average energy requirement for an adult is 8700kJ/day.

Saturated Fat

Products should haveor


Products should containor


Products should have or 100g

Additional positive nutrients such as fibre and protein are also be considered as well as the whole food content of ingredients such as fruits, nuts, legumes and vegetables.

Let’s look at the Nutrition Information Panel (NIP) of a cereal as an example of a 5 star rating.

Using the parameters listed above, we can see that per 100g this product meets the requirements for Saturated Fat (0.5g/100g), and has quite a substantial amount of fibre (29.5g/100g), making this cereal almost one third fibre, not bad. Although it has three times the sodium amount recommended above (360mg/100g) and sugar is greater than 5g/100g (16.7g/100g), the high fibre and low saturated fat still weigh heavily enough to give it 5 stars.

Is it basically, the more stars the better? Well, sort of. This system is successful at highlighting foods that contribute positive nutrients, that can be enjoyed as part of a balanced diet. As with any rating system however, the stars are not without limitation.

Let’s look at another example, now of a product with a 4 star rating, Coles Almond Milk.

Ingredients: Water, Ground Almonds (2.5%), Maltodextrin(Corn), Natural Vanilla Flavour, Mineral Salt(170), Vegetable Gums (418,415), Salt, Vegetable Emulsifier(322) (Sunflower). (Source:

Again, using the parameters, this product is low in Saturated Fat (0.1g/100mL), Sugar (0.3g/100mL) and Sodium 45mg/100mL). It also contributes Calcium (70mg/100mL). However if you look closer at the ingredient listing, you will see that water is the first ingredient, and that almonds only make up 2.5% of the product. So although almonds are a nutritious food, Almond Milk is little more than almond flavoured water, with some additives thrown in.

Reduced fat cow’s milk (5 stars) offers much more in the way of calcium (145mg/100mL) and protein (4g/100mL) compared to just 0.4g/100mL if you drink almond milk. Although there is only 1 star between these two “milk” products, there is a significant difference in what these products are offering in nutrition to your diet.

Lastly, some considerations:

  • This is a voluntary system, brands can chose to adopt the front of label packaging (FOPL) or not. Just because a brand does not display FOPL, does not necessarily mean it is an unhealthy or healthy product. This would require you to check out the NIP further.
  • Items that have a high number of stars may be nutritious, however this is not a green light to over-consume this item, it should still be enjoyed with other food groups.
