European study highlights impact of food labels
A pan-European study by the European Food Information Council (EUFIC) has provided further insights into the shopper relationship with food labels.
The study, which questioned 17,300 people from various European countries, both in supermarkets and at home, found that only 18% of Europeans regularly look for nutrition information on food packaging in-store.
Independent market research agencies carried out the field work in each country. Results showed, however, that the better established forms of nutrition information on labels such as the Guideline Daily Amount (GDA) scheme, was widely recognised and understood by shoppers.
“While there are several nutrition labelling schemes across Europe, our findings show that people recognise them and generally know how to use them to make informed nutrition choices,” commented Professor Klaus Grunert of the University of Aarhus, Denmark, who conducted the study for EUFIC. “Nutrition labelling should be seen as a key element in a rounded public health strategy.”
Real life in-store behaviour
Among those looking for nutrition information, the Nutrition Table is the most frequently mentioned source of nutrition information followed by the GDA labelling system (commonly referred to as the Daily Intake Guide here in Australia). In countries where food additives were identified as important information, the ingredients table was also cited.
Colour coded schemes such as traffic lights also met with high levels of awareness but were open to some misinterpretation as people tended to exaggerate the meaning of the colour-coded levels, with 73% of people believing that a ‘red’ light indicated they should avoid eating a product.
Sweden, which uses a keyhole logo to identify the healthier product in a food category, had the highest awareness of any labelling system at 95%. Subjective and actual understanding of the system was also the highest, yet usage was lower. Notably, 61% of shoppers said they would look for other information even if the keyhole logo was present.
Consumers were, fairly confident that they understood the labelling systems. And, across all countries, at least half could correctly solve a number of tasks involving interpretation of GDA and other nutrition information on labels.
A new finding was that people spend an average of 30 seconds selecting a product. By comparison to previous studies, this is substantially more time than previously observed. The UK was lowest at 25 seconds per product, with the highest average time clocked at 47 seconds.
Shoppers are most likely to look for nutrition information when buying yoghurts, breakfast cereals and ready meals. Convenience and health clearly played a role in purchasing decisions, while taste was the most important deciding factor across all categories in most countries.
Labelling of key nutrients
Calories was the information most frequently sought by shoppers in four out of the six markets. However, UK consumers looked for fat content before calories, whilst Swedish consumers looked equally for sugar and fat followed by calories. Fat was among the top three in all countries as was sugar, whereas salt was in the top 5 only for two countries. Other information sought included food additives, vitamins and fibre.
Calories and fat levels drove healthier choices, but salt and saturated fat levels were largely ignored. Younger consumers were better at finding the right answers, and people with more nutrition knowledge gave more correct answers.
Higher socio-economic status positively impacted upon looking for nutrition information and the level of nutrition knowledge.
Getting it right and getting it wrong – over & under estimations
When probed as to the fat, sugar or salt content of foods, the majority of respondents were able to answer correctly. When they got the answer wrong, respondents consistently over-exaggerated actual levels . Similarly, all countries over-estimated the calorie content of alcoholic drinks.
Across Europe, people tended to significantly underestimate the calories (energy) expended by everyday activities. While 46% or less answered correctly when asked how many calories the average adult needs per day. Women fared slightly better than men.
Broader nutrition messages are being understood but still confusion about fats
As well as probing the use and understanding of labelling, the surveys questioned peoples’ general levels of nutrition knowledge. More than 95% knew they should increase their fruit and vegetable consumption, over 73% answered correctly about eating more wholegrain, and over 65% about fibre.
Knowledge of consuming more Omega 3 fatty acids ranged from 47% to 88%. However, mono-unsaturated fats and polyunsaturated fats seem less understood, with under half of all respondents correctly thinking they should consume more. Over 60% state you should eat less or try to avoid trans fat (TFA), and 68% for saturated fat.
“I am surprised that the average European consumer spends 35 seconds selecting a food product. However, looking for nutrition information is not top of mind for most consumers,” Professor Klaus Grunert concluded in his discussion on the key findings of the study.
