Consumers misled by gluten-free foods, study finds
(Prague, 11 May, 2017) Gluten-free products cannot be considered as sufficient substitutes for their gluten-containing counterparts, prompting scientists to call for the reformulation of gluten free items with healthier raw materials to ensure healthy childhood nutrition.
The outcomes of the study(1), presented today at the 50th Annual Congress of the European Society for Paediatric Gastroenterology Hepatology and Nutrition, show that gluten-free items have a significantly higher energy content and a different nutritional composition to their gluten-containing counterparts. Many of the gluten-containing products — especially breads, pastas, pizzas and flours — also contained up to three times more protein than their gluten free substitutes.
The imbalances highlighted in the study could impact children's growth and increase the risk of childhood obesity.
The study assessed 654 gluten-free products, which were compared with 655 gluten-containing products. Further key findings include:
- Gluten-free breads had significantly higher content of lipids and saturated fatty acids
- Gluten-free pasta had significantly lower content of sugar and protein
- Gluten-free biscuits had significantly lower content of protein and significantly higher content of lipids
A gluten-free diet is followed as a life-long therapy for patients with coeliac disease, including children, which now affects around 1% of the European population (2). As gluten-free products replace many staple foods in the diet, such as bread and pasta, the intake of these products therefore play a very important role for many consumers. A growing number of people are also turning towards these products as a wellbeing choice, even when they are not diagnosed with coeliac disease.
ESPGHAN expert and lead researcher, Dr Joaquim Calvo Lerma, explains "As more and more people are following a gluten-free diet to effectively manage coeliac disease, it is imperative that foods marketed as substitutes are reformulated to ensure that they truly do have similar nutritional values. This is especially important for children, as a well-balanced diet is essential to healthy growth and development."
Experts are warning that not only are gluten-free products different in their nutritional composition, but consumers may not be aware of these unhealthy variances due to poor nutritional labelling.
Dr Sandra Martínez -Barona, fellow lead researcher, states that the nutritional labelling on gluten-free products should be clearer. She comments "Where nutritional values of gluten-free products do vary significantly from their gluten-containing counterparts, such as having higher levels of saturated fat, labelling needs to clearly indicate this so that patients, parents and carers can make informed decisions. Consumers should also be provided with guidance to enhance their understanding of the nutritional compositions of products, in both gluten-free and gluten-containing products, to allow them to make more informed purchases and ensure a healthier diet is followed."
Daciana Sarbu MEP, Vice-Chair of the Committee on the Environment, Public Health and Food Safety, adds "EU law provides for mandatory nutritional labelling of pre-packed foods. However, food products that are not pre-packed, which could include gluten-free bread or pizzas, are not subject to the same labelling requirements. In this case, consumers could be less aware of important nutritional differences with potentially significant health impacts. I have always supported so-called 'traffic light' labelling to facilitate easy comparison between products for key nutrients including protein, fat and sugars."
