Health Star Rating: how many stars will your product get?

In Australia and New Zealand, the front of pack carries stars: from half a star to five, in half-star steps. The system is voluntary, which does not make it optional: shoppers compare stars on shelf, and a range that displays nothing reads as a range with something to hide. The question is how many stars your product earns, and what it would take to gain one.

A voluntary system that may soon become mandatory

The Health Star Rating is an Australian and New Zealand government scheme. It is still voluntary, but the uptake target set by food ministers was missed. At their request, the FSANZ agency is now assessing whether to make it mandatory (Proposal P1067).

For an exporter the consequence is simple: the calculation becomes necessary when the market is being considered, not when the artwork goes to print.

From half a star to five

The scale has ten positions. It reads at a glance, which is exactly its commercial value — and exactly its danger: half a star less than the product next to it is visible on shelf.

The drink above earns one and a half stars. The same recipe is rated E by the European Nutri-Score: the two systems agree here, but they are not interchangeable and nothing guarantees they will agree on the next product.

What moves half a star

The Health Star Rating belongs to the summary-rating family: it balances what should be limited against what counts in the product’s favor.

• What counts against: energy, saturated fat, total sugars and sodium.
• What offsets: fruit, vegetable, nut and legume content, together with fiber and protein.

That offsetting is the practical difference from UK traffic lights, which allow none. Here, raising the fruit or legume content genuinely redeems a profile, which opens room to maneuver in reformulation — provided you know which lever pays best.

The category changes the scale

A trap for newcomers: there is no single scale. The calculation depends on the category the product belongs to — drinks are not rated like solid foods, and dairy products fall under distinct rules.

Putting a product in the wrong category does not produce a visible error. It produces a plausible, wrong rating, detected only when somebody redoes the calculation. The category therefore belongs on the product record, exactly like the nutritional composition.

Compute it during formulation, not after

Half a star often comes down to very little. The only way to know whether an adjustment tips it is to recalculate the rating on every trial, on the formula in progress, exactly as you would with cost or nutritional values.

It is also what lets you arbitrate between markets: a change that gains half a star in Australia may do nothing to the UK marking, and may or may not remove an octagon in Latin America. On a single record, those effects can be read together.

Your stars are decided upstream, in the recipe, not at artwork sign-off. If you want to know how many your references earn, let’s talk.
