Shopper Research - Guideline Daily Amounts

GDA labels on the front of packs seemed to have connected with consumers in a meaningful and significant way.

In addition to the verbatims from consumers who took part in our tracking study which provide insight in their use, the study revealed that quantitatively, 76% of shoppers are aware of the term GDA and 83% now recognise the labels themselves.

87% think the labels are easy to understand, 63% have used them to check their food choices and even though they are now on over 20,000 products, 84% would like to see them on even more.

The four dips of research have shown steady and increasing use of the labels. In November 2006 49% had used them; by March 2007 this was 54%; by September of the same year 57%; and in April 2008, 63%.

There is evidence to suggest that those shoppers who use them are doing so to compare and contrast items: 84% use them to pick a product with a specific low nutrient score, 83% to compare similar products before purchase and 80% to check that certain products stay below a level that the shopper has set.

In short, GDA labels on the front of packs are working as planned.

While the purpose of the Millward Brown research was not to compare multiple traffic lights (MTL) labels and GDA labels side-by-side or investigate consumer usage of MTL labels in depth, it did highlight that whilst MTL labels seem simple to understand in principle, they are not so clearly understood in practice.

It did ask a limited number of questions about traffic light labels which revealed some interesting findings. Although 76% of shoppers say they can absorb information from the various MTL labels in the market quickly and 76% also say they are easy to understand, when tested, less than one consumer in 10 understood that a particular product was being colour coded per 100g, and not per portion.

This could cause considerable shopper confusion, with the consumer thinking, for example, that because a ready meal is amber for salt, it contains moderate levels of salt in each portion when, in fact, it could contain as much as 2.2g – more than 36% of the adult GDA.

About the Millward Brown consumer research

The studies[1] were commissioned to track awareness, understanding, usage and influence of GDA labelling in the UK. The research took place during four separate time periods or 'dips' in order to evaluate how awareness of, and attitudes towards the Guideline Daily Amount labelling system are changing over time.

The key objectives were to monitor:

  1. Whether awareness and understanding of GDA labelling has increased as a result of on-pack visuals, above-the-line advertising and recent advertorial activity
  2. Whether consumers increasingly use labels to help them with decision-making
  3. Help understand how consumers use the scheme in practice and what support they need to increase understanding and drive further use
