The use of blended food administered into an enteral feeding tube is commonly referred to as following a ‘blended diet’. Alternative descriptions exist including liquidised tube-feeds, blenderised food, liquidised diet and pureed table food (1). This mode of enteral tube-feeding has been met with caution, as some professionals raised concern that blended diet could be unsafe in comparison to commercially prepared enteral formulas (2). Professional consensus indicates use of blended diet has increased in the UK. Despite the perceived increase in use, blended diet has been under-researched. It is unclear if the perceived increase in risk (nutritional deficiency, feeding tube blockage and infection) is occurring or with significant frequency compared to those using commercial enteral formula alone.

Furthermore, research has suggested blended diet can have physiological benefits such as improvement in symptoms of vomiting, reflux and abnormal bowel habit (3-7). Robust research is needed to investigate why blended diet can have beneficial effects for some tube-fed individuals. In addition to physical benefits, social and emotional benefits have been reported by the parents and carers of tube-fed children and young people (3-7). In surveys, UK dietitians have reported variation in their ability to support families who have chosen blended diet due to a lack of clear professional guidance (8,9). This position statement aims to support UK dietitians in clinical practice (in both paediatric and adult settings) to ensure tube-fed individuals receive effective, evidence-based, equitable and quality care.

Practice Toolkit: The Use of Blended Diet with Enteral Feeding Tubes is available for dietitians to download here.

The purpose of this statement is to:

  • Create a culture where tube-fed individuals and their families and/or carers feel able to openly and honestly discuss the feeding plan they follow or plan to follow with the dietitians involved in their care.
  • Create a culture where dietitians feel supported professionally, to raise the topic of blended diet with their patients and other healthcare professionals and offer blended diet as an option to tube-fed individuals where they deem it appropriate.


  • The dietitian is the expert in enteral tube-feeding and should lead multi-professional discussions in relation to blended diet, in the best interests of the individual under their care. Dietitians can suggest blended diet as an option where they believe there to be potential physiological, social or emotional benefits to the tube-fed individual and their family.
  • For the majority of tube-fed individuals, particularly those who are tube-fed, short term in hospital; the use of commercially prepared formula, designed specifically for enteral tube-feeding remains the first line choice.
  • It is acknowledged that commercial formulas, irrespective of type or brand, are not tolerated by a small group of long-term tube-fed individuals. The reasons for this are not understood; the use of blended diet may provide clinical benefit in this patient group.
  • The jejunum does not have the same food storage capacity or gastric acids, which protect against infection, in comparison to the stomach. Therefore, it is likely to be safer to administer blended diet into a gastrostomy rather than a jejunostomy.
  • A shared decision-making approach to care, alongside employer’s clinical governance procedure should be followed by the dietitian (10). The dietitian should ensure families receive individualised information they need to enable them to make an informed decision. Consideration should be given to patients with complex medical conditions and those who may be immunocompromised. Planning and preparing blended diet requires a significant commitment and families should have realistic expectations of the labour and financial cost involved. The shared decision should be justified and clearly documented in the individual’s records by the dietitian.
  • If a dietitian’s employer (trust or board) has a policy which specifically prohibits the use of blended diets, dietitians should adhere to it. This BDA policy statement cannot supersede an employer’s stated policy. However, dietitians should use this BDA policy statement and the evidence contained within it to encourage a change in any trust or board policy that prohibits the use of blended diets. 
  • For children >1-year-old and adults, blended diet can be used either as a sole source of nutrition or in combination with commercially prepared enteral formula.
  • Blended foods should not be introduced before weaning age (around 6 months). Small amounts of blended food may be introduced alongside breast milk and/or infant formula in line with current recommendations for oral complementary feeding (11). 
  • Steps should be taken to educate the family to ensure blended diet is used as safely as possible. This should include advice on food hygiene and storage, enteral feeding tube care and education on a healthy balanced diet. The level of education and dietetic input needed should be tailored to the individual needs of the family.
  • The dietitian should work with other professionals and agencies to facilitate the implementation of blended diet in all care settings attended by the tube-fed individual. For example, respite care, school or college. Ultimately, the decision to provide blended diet rests with the individual care provider.
  • Families should be made aware that the provision of blended diet in the inpatient setting is dependent on the individual trust’s policy and food preparation facilities. Blended diet is less likely to be permitted in the ICU/HDU setting. Patients who are fed blended diet in the community should have a plan in the case of admission.
  • Administration of blended diet is likely to be easier with some enteral tube-feeding devices in comparison to others. Further information regarding choice of enteral feeding tube is provided in the updated practice toolkit. However, individual manufacturers ‘information for use’ should be clarified when a decision is made to administer blended diet.
  • The increasing prevalence of blended diet should be considered when reviewing enteral feeding contracts as this may have an impact on the service level in place.
