Press Release

13th February 2014


• App provides ‘at a glance’ colour coded nutrition information for over 80,000 products by scanning the barcode - remaining products to be ‘crowd sourced’ by users.

• Allows customers, for the first time, to switch to healthier products based on established nutrition criteria.

• Developed by leading health experts and supported by 13 organisations as a FREE and IMPARTIAL tool to improve the nation’s diet.

Launching today [13th February] FoodSwitch is the first ever smartphone app that enables UK consumers to make healthier and smarter food and drink choices. Putting consumers in control whilst out shopping, FoodSwitch will help customers make more informed decisions when purchasing their weekly shop, in turn reducing their risk of ill health through poor diets.

FoodSwitch allows users to scan the barcode of over 80,000 packaged food and drinks sold across major UK supermarkets using their smartphone camera to receive immediate, easy to understand ‘traffic light’ colour-coded nutritional information along with suggested similar, healthier products.  It is now easier than ever for consumers to reduce high levels of fat, salt and sugar in their families’ diet.

When the barcode of a food or drink product is scanned by a smartphone, FoodSwitch instantly searches the database and identifies healthier products by comparing the overall nutritional value of the product to existing Government criteria.  The overall nutritional rating takes into account a range of different factors important to general health including fats, sugars, salt, protein and fibre [Ref 1].

Many manufacturers have been hiding behind their labels for years, and with the new voluntary front of pack nutrition labelling scheme being rolled out this year, FoodSwitch gives customers the perfect opportunity to get to grips with what the labels mean, and to better understand what is in their food!  The app colour codes each product by the content of four important nutrients - total fat, saturated fat (saturates), sugars and salt:

● Red – (high) try to choose products with less red circles.
● Amber – (amber) this choice is OK, but going for choices labelled green is better.
● Green – (low) the more green circles, the healthier the choice.

FoodSwitch was developed by leading UK nutrition research experts; Consensus Action on Salt and Health (CASH), the Medical Research Council Human Nutrition Research, The British Heart Foundation Health Promotion Research Group, and the Nuffield Department of Population Health and Nuffield Department of Primary Care, University of Oxford, and led by The George Institute for Global Health (TGI).  FoodSwitch is further supported by nine UK organisations [Ref 2].

Bruce Neal, The George Institute for Global Health and inventor of FoodSwitch says:
FoodSwitch is all about putting power back into the hands of the community.  At the same time as recommending healthier alternatives to shoppers, the photographs of missing products sent in by users give us a complete picture of what’s in the food supply.  This is information that used to be the preserve of industry - we can now use it to hold big businesses directly accountable for what they are putting on the shelves.”

Example of FoodSwitch App:

Katharine Jenner, Nutritionist and Campaign Director of CASH and FoodSwitch UK says: 
FoodSwitch puts the shopper back in control. It is not about telling people to stop eating or avoid certain foods with red colours but rather highlighting differences in products. This new app will allow people to take responsibility for their individual and their family’s health, and improve their eating habits in an easy and fun way.

For products that are not listed in the database, shoppers are invited to ‘crowd source’ the information by using the app to take photos of missing products, which will then be validated and added to the database for future use. There is also a feedback function available [Ref 4]. Data is also protected with FoodSwitch - when you access and share information on FoodSwitch, the app will not collect any identifiable data about you.

Dr Peter Scarborough, The British Heart Foundation Health Promotion Research Group, Nuffield Department of Population Health, University of Oxford says:
With all the messages about health in the public eye, it is hard for consumers to know what is ‘healthy’.  The established nutrition criteria used in the app shows customers products that are healthier overall, not just whether they are higher in salt, fat or sugar.”  

Professor Susan Jebb, Nuffield Department of Primary Care Health Sciences, Oxford University, says:
A poor diet is responsible for tens of thousands of premature deaths every year in the UK. People will be able to use this smartphone technology to swap the foods in their regular shopping basket for healthier options to help themselves and their families to cut their risk of diabetes, heart disease and some cancers.

Dr Toni Steer, Public Health Nutritionist, Medical Research Council Human Nutrition Research says:  
FoodSwitch makes it quicker and easier to compare nutritional labels, which will hopefully support people in making healthier choices.

Ref 1 – About FoodSwitch
FoodSwitch provides nutritional information and suggested healthier alternatives based on an adapted version of existing nutritional profiling criteria (‘A’ and ‘B’ below). It has been modified by The George Institute for Global Health for use in the FoodSwitch App.
A) Colour coded labelling
The ratings for red, amber and green for each nutrient are based on the Department of Health Guide to Creating a Front of Pack (FoP) Nutrition Label for Pre-packed Products Sold Through Retail Outlets:
Traffic light labels are given per 100g/ml.  
Energy (calories and kilojoules) are not coloured.
B) Healthier choices
Products have been placed into similar categories for comparison by the FoodSwitch UK team. The nutrient profile of each product is defined by The Department of Health’s Nutrient Profiling Technical Guidance
