What is the Health Star Rating?

The Health Star Rating (HSR) is a voluntary front-of-pack nutrition labelling system for packaged food and drinks. It's designed to help you make healthier choices as you shop. The star ratings range from ½ to 5 stars and rate the nutritional profile of the product — the more stars, the healthier the product choice. Although the system is voluntary, a lot of products have started displaying Health Star Ratings since it was launched in 2014.
