To stay heart healthy it's important to know that what we eat is low in fat, salt and sugar. But in the daily dash around a crowded supermarket it's not always easy to see just what's in the foods we're buying.

Many food manufacturers and retailers persist in using Guideline Daily Amounts (GDAs) labelling on packs, which shows what percentage of the recommended daily amount of fat, salt and sugar the product contains. By comparison, traffic light labelling provides a clear guide to the level of fat, salt and sugar in products using a simple red, amber and green code.

The BHF is one of the leading organisations backing the call for all supermarkets and food companies to switch to traffic light colour coding. In 2007, we stepped up the campaign to make it easier for all of us to make healthy choices by lobbying UK and European governments to make traffic lights mandatory on all UK food packaging. We also distributed 100,000 wallet-sized ready reckoner cards, through our heart health magazine, to help shoppers convert GDA to traffic lights.
