Five colours are best for nutrition labels: French advisory body

A five-colour nutrition label is more effective than three, says French advisory body - but industry has slammed it as simplistic while critics say it is more confusing than traffic-light labels.

The report by the HCSP (Haut conseil de la santé publique) said a five-coloured system had the three most important factors for any nutrition label – it was eye-catching, simple to understand and effectively translated numerical nutritional values into meaningful information.

“After reviewing the feasibility of different scores and proposed systems at national and international level and after testing the database on the nutritional composition of foods on the French market, the HCSP considers that only the five-colour system meets the criteria of relevance and feasibility for a synthetic nutritional information system.” 

It also said scientific studies had shown the five-colour system to have high ‘consumer acceptability’, although a key drawback was that it had not been tested in real-life conditions.

While the HCSP recommended using the nutritional threshold score developed by the UK’s Food Standard’s Agency, it "optimised"​ the calculation method in order to allow certain foods –  such as cheese which has a high-fat content – to escape being branded red. It suggested that, because of its high protein and calcium content, cheese could be classed as pink.

The report recommended that the nutrition label be accompanied by a public information campaign, and called for more research into public perception of the median orange colour as well as an evaluation of the label's impact on businesses and consumers.

Simplistic and stigmatising?

But French food industry association ANIA called the nutrition label simplistic saying it applied a "medicalised and theoretical"​ approach to diet.

“A balanced diet of an individual cannot be reduced to a coloured sticker on a product. These nutritional scoring systems unfairly stigmatise foods as they are based on theoretical calculations taking into account 100 g product without distinguishing actual consumption by consumers.”

It said industry had been working to improve the nutritional content of food in private-public partnerships, saying over thirty such collective and individual charters had been signed recently.

ANIA president Jean-Philippe Girard said: “The current debate on nutritional information is very important. We must avoid the pitfall of reducing it to five colours. ​Adding: "Real condition experiments are needed to build a suitable and efficient device.”

Meanwhile for industry watchdog FoodWatch, a five-colour system was inefficient because it was not simple enough. “A code that has five colours and five letters is not easy to interpret at a glance,” ​it said. 

Instead, FoodWatch called for a three-colour traffic light code such as the one used in the UK. “It draws on the universally understood traffic lights: green for a healthy product, orange when it is necessary to consume in moderation, and red for the products to avoid.”

Drawn up in June but made public this week, the HCSP report was commissioned by France’s Directorate general for health. A health bill is currently being examined by the French Parliament and includes an article calling for symbolic or graphic information to represent nutritional values.

Fantastic article, most people say that they want to get in shape, yet exercise and nutrition are often forgotten, yet this is the base not only for losing weight, getting fit but also for being health and more confident in ourselves. So in my opinion besides exercise the most important for getting fit and losing weight is to learn the basics of nutrition. While you learn about how it works get a meal program that works so you can see some results while you learn. This is how i started and it really made a big difference in all the areas of my life.

I highly recommend the following (not related to me in any way), which does not get lost in the details, and focus on the essential concepts and gives you practical advice and a good game plan to get you started:

Nutrition Labels

Posted by Tonderai,

I dont understand why you even need these labels. Consumers should know when they buy something whether its nutritional or not. I dont need some labels telling me that fruits and vegetables are nutrition. I mean, we already know that they're nutritional. Its just common knowledge. The problem these days isnt WHAT we eat. But HOW and WHEN we eat it. Personally, I use a Nutrition book ( to keep track of how i should be eating and its been working like a charm. Check it out if you want, but my point is, these labels are an unnecessary waste of money and time for the government to be implementing such things
