Sir, Sue Davies is right in saying we need to capitalise on new EU rules on food labelling to get the very best for shoppers (The Saturday Essay, 16 July). While MEPs stopped short of making front-of-pack traffic-light food labels mandatory in Europe in a vote last month, they did vote for improvements in the nutritional content we'll see, and they recognised that companies and supermarkets already using traffic-light labels should be allowed to continue.

The Lords Science and Technology Committee also threw its weight behind the traffic-light scheme by calling directly on the UK government to take steps to implement it. The committee's report, which looked at how to help people make healthier choices, highlighted strong evidence that people find traffic light colours easiest to use to make quick decisions about how healthy the food is they're about to buy. The report asked the government to explain why current policy is not in line with available evidence.

The government should do everything it can to get front-of-pack traffic-light labels on to food packs, which could make a big difference when it comes to tackling our growing obesity epidemic.
