GDAs explained

There are 93 adopters (June 2010) of the GDA labelling scheme: five retailers, three foodservice organisations, two convenience store chains and 83 manufacturing companies. The adopters have introduced easily recognisable GDA icon labels, which feature prominently on the front of pack of over 20,000 product lines. This amounts to a massive 50% of all UK retail food and drink packs.

The GDA information for protein for an adult woman (45g) and man (55g) and children (24g) (aged 5-10 years) - for more information view GDAs for different nutrients.

Percentages are included because they quickly and easily clarify the nutritional content of each food product in the context of a person's whole diet.

This allows you to make informed comparisons between products so you can select the ones that best suit your needs.

Further details on GDAs for children are available on the Institute of Grocery Distribution (IGD) website. The youngest age band that the IGD set GDAs values for was 4-6 year olds - for more information view: IGD Best Practice Guidance on the Presentation of Guideline Daily Amounts.

For details of the nutrient requirements of babies/toddlers, the British Nutrition Foundation website is a very useful source of information.

Nutrition labelling is voluntary, unless a nutrition claim is made, so it is fine to have Big 4 (eg, energy, protein, carbohydrate and fat) in the nutrition table. However we recommend that the full GDA label (all 5 icons) is represented on the label, and not just two GDA icons. FDF has produced a style guide to ensure labelling consistency across the products and brands.

If you have a small pack, FDF and CIAA (the European Confederation of the Food and drink industries) recommendation is to simply add the Energy GDA icon (calories). This is what you would see on the chocolate or cereal bars for example.

Having two icons would give the impression that you are “cherry picking” the nutrients that are more convenient for you rather than making as much information available to consumers as possible.

If you want to know the contents of the drink for the purposes of the back of pack nutrition table, you will need to get it analysed by a food technologist like Leatherhead Food International or Campden BRI.

You will need to calculate the nutritional value of your drink per 100ml and per portion/pack depending how big your bottles are. You can then use our style guide for GDAs as a guideline to develop on your pack a visually consistent GDA front-of-pack scheme.

Women's GDA of 90g total sugars does include natural sugars from foods such as fruit, vegetables, dairy products and cereals, and also includes sugars added to processed foods and drinks.

GDA labels show the level of calories, sugars, fat, saturates (saturated fat) and salt contained in a suggested portion of food and, more importantly, tell you what percentage of your Guideline Daily Amount for calories, sugars, fat, saturates (saturated fat) and salt, each portion comprises.

This enables you to build a picture of what you are eating in the context of your whole diet and make a better informed choice about what you are eating.

Food and drink manufacturers across Europe who apply GDA labelling to their products do so voluntarily. The Food and Drink Federation backs the GDA scheme and as such has developed an industry style guide for its members. In this style guide you will find information relating to the size of the GDA icon for certain packaging sizes.

On a separate note, The Food Information Proposal is a piece of regulation currently being negotiated in Europe which will govern food labelling. On 16 June 2010 MEPs voted in plenary in the European Parliament on the Food Information Proposal.

MEPs supported GDAs on a mandatory basis and energy front of pack; FDF members have long supported GDA labelling as the best way to help consumers make informed choices about the food they buy.

This is only the first step in a lengthy process to agree the Regulation. The Council is also negotiating the dossier, and the European Parliament is due to have a second reading in Spring 2011. The Food information proposal contains guidelines on labelling legibility and font size. More information about the Food information proposal.

GDA labelling is based on per portion information whilst Traffic Light labelling is applied per 100g. Combining the two approaches across all categories provides some confusing results.

For example a 10g portion of a spread containing 0.2g of salt would have a red label for salt, whilst a ready meal containing 2.2g of salt would have an amber label. Another example is ketchup, which would be labelled red for sugar (based on 100g), but a normal 20g serving would only contain 5% of the GDA and lets face it, who eats 100g of ketchup in one go?

Consumers pay more attention to red than green. Food Standards Agency (FSA) research showed that if a product had more than two red labels, consumers would reject it as too unhealthy. While this may be the desired result, it would also mean consumers may reject many products that include a significant amount of essential nutrients such as cheese, yoghurt or nuts. If GDAs are colour coded, consumers are more likely to make a snap judgement based on the colour of the GDA rather than the actual GDA percentage.

Similarly, it may be difficult for a consumer to interpret the overall nutritional 'worth' of a product that displays, for example, two red lights and two green lights, even if this sits alongside GDA values.

Within the FSA scheme colour bands are wide, so a product would have an amber colour for salt, if it contained anything between 0.3g and 1.5g per 100g. A product with 5% of the GDA for salt, would therefore be coded the same as something with 25% of the GDA for salt, so shoppers may not spot the healthier option.

Traffic Light colour codes are recommended by the FSA for certain composite foods and they publicly acknowledge that they are not intended for use across all categories.

The food industry have demonstrated that GDA labels are effective in their current form and adding a further level of complexity by overlaying colours may not serve to simplify them at all. We believe that the key to making consumers more food literate lies in encouraging them to look at what's inside the food they are buying and think about it in the context of their whole diet.

The GDA for carbohydrates for a 5-10 years old child is 220g. Please see this table in this section of our website. The GDAs for the purpose of labelling are for women.

There is currently a revision of the labelling legislation taking place in Brussels and it will include GDA values.

GDA stands for Guideline Daily Amount and is the recommended amount of specific nutrients an adult should consume each day.

GDAs and nutrition information have been available on the back of packs for many years.

Therefore, introducing a shorthand version of this information on the front of packs was a logical step for industry in seeking to make labelling clearer and more accessible for people.

The use of GDAs on food labels provides an accurate means for people to tell if a product contains a higher or lower amount of a particular nutrient, compared to another product. This enables small but positive changes to their diet.

Being able to quickly identify the levels of nutrients in a product also makes it simple for you to focus on the nutrients of interest to you, e.g. calories, fat or sugars. Again you can then see more clearly how to make simple changes to improve your diet.

More information about Guideline Daily Amounts (GDAs) explained.

The GDAs for women, men and children can be found on the following page of our website: GDAs explained.

Please remember tha GDAs are maximum levels and not targets (apart from fibre); this means that you should try not to go above those levels.

On a food label you will often see Guideline Daily Amounts (GDAs) provided for energy and some nutrients like fat, saturated fat, sugars and salt. GDAs have been defined for men, women and children of different ages, but what you usually see are the values for an 'average' adult.

Recommended Daily Allowances (RDAs) are different to GDAs, and only relate to vitamins and minerals. You will only see RDAs on food labels when the amounts of vitamins and minerals present are stated, in which case it is a legal requirement to also state the %RDA. These values are defined in food labelling legislation.

How they are defined varies depending on the vitamin or mineral but will include consideration of the scientific evidence regarding prevention of disease, health benefits and safety levels of high intakes.
