Food First/Food Enrichment
Although there is limited research into this area, studies have shown that increasing the energy density of meals through food enrichment can increase an individual’s overall caloric intakes up to 30% (Odlunds et al 2003). Other studies have indicated that dietary counselling gave comparable increases in weight to oral nutritional supplement use (Baldwin and Weekes, 2012).
If a patient has a poor appetite, problems with eating, or has lost weight recently, it is important that the food and drinks taken contain as much energy and protein as possible.
Dietary advice could include:
Little & often: aim to have three small meals plus two to three nourishing snacks in between (eating every 2-3 hours) as trying larger meals may over-face the patient (see table 1 for snack ideas)
Choosing full fat and sugar products rather than ‘low fat/sugar’ as they contain more calories. e.g. Choose full cream milk instead of skimmed/semi skimmed milk and normal butter/spread rather than low fat spread.
Nourishing drinks can be a simple way of increasing calories intake. Options include malt drinks, milk based coffee, hot chocolate, fresh fruit juices, milkshakes, smoothies or enriched soups.
Food Enrichment: Involves using every day food items to enrich the diet with energy and protein such as using adding butter, cream, cheese, full fat milk, skimmed milk powder, oils, crème fraiche to foods to boost their energy and protein content (see Table 3). Please note that some foods only add energy to food while others also provide protein which is required for tissue growth and repair (see Table 4).
Consider a multivitamin & mineral supplement as those eating small amounts or a limited variety of foods may not have adequate micronutrient intake.

Oral Nutritional Supplements (ONS)
Oral Nutritional Supplements (ONS) are sterile liquids, semi-solids or powders, which provide macro and micro nutrients. They are widely used within the acute and community health settings for individuals who are unable to meet their nutritional requirements through oral diet alone. ONS use must be approved by the Advisory Committee on Borderline Substances (ACBS). Indications for use include:
- Short bowel syndrome
- Intractable malabsorption
- Pre-operative preparation of undernourished patients
- Inflammatory bowel disease
- Total gastrectomy
- Bowel fistulae
- Disease related malnutrition (chronic/acute)
ONS may be prescribed in the short term during acute illness, but also for individuals with long term chronic conditions. The role of ONS is to complement nutritional intake, and simultaneous information around improving oral intake should be provided.
Some ONS are available to buy over the counter in supermarkets or pharmacies (usually in powder form which are mixed with milk or water) but the majority of ONS are only available on prescription ideally following advice from a registered dietitian. ONS often contain macronutrients (protein and/or energy) and micronutrients (vitamins and minerals) at varying levels of concentrations. Therefore, not all ONS are nutritionally complete, meaning that they cannot be used as a sole source of nutrition. Individual dietetic assessment will take into account nutritional requirements and taste and texture preferences to ensure a tailored prescription is advised.
The following table shows the most common types of ONS available:
|Juice type||Volume ranges from 200-220ml with an energy density of 1.25-1.5kcal/ml. They are fat free|
|Milkshake type||Volume ranges from 125-220ml, energy density ranges from 1-2.4kcal/ml. Also available with added fibre.|
|High-energy powders||Volume ranges from ~125-350ml, ideally made up with full cream milk to give an energy density of 1.5-2.5kcal/ml.|
|Soup type||Volume ranges from 200-330ml. Some are ready mixed and others are a powder and can be made up with water or milk to give an energy density of 1–1.5kcal/ml.|
|Semi-solid/dysphagia ranges||Range of presentations from thickened liquids (stage 1 and 2) to smooth pudding styles (stage 3), with an energy density of ~1.4-2.5kcal/ml.|
|High protein||Range of presentations; jellies, shots, milkshake style containing 11-20g of protein in volumes ranging from 30–220ml.|
|Low volume high concentration (shots)||These are fat and protein based products that are taken in small quantities (shots), typically 30-40ml as a dose taken 3-4 times daily.|
What else should be considered?
- Further information regarding suitability of ONS should be checked with individual manufacturers for example, gluten or lactose free, halal or kosher.
- ONS should be used with caution in those with dysphagia to ensure the correct consistency is provided. Thickeners can be added to obtained the recommended consistency.
- A range of flavours should be offered to avoid taste fatigue.
- There is an emerging group of ONS which are designed for individuals over the age of 65 years who can be at risk of vitamin D deficiency.
- Other products may be useful in patients with specific medical conditions where fluid and electrolyte balance is important. Patients with short gut may not tolerate heyperosmolar ONS as they may increase stoma losses.
ONS should not be prescribed without being monitored to ensure that they remain appropriate and are being taken as prescribed. ONS may be stopped when:
- Dietary intake is meeting nutritional requirements.
- Weight has increased to target.
- BMI is within healthy range.
- The individual’s medical condition has changed, e.g. an individual with a swallowing difficulty recovers some/all of their functionality.
- The individual can no longer tolerate them due to taste fatigue.
Nutrition by Mouth
A number of strategies can be used to aid those with inadequate food intakes. These may include food enrichment, regular snacks and nourishing drinks. These strategies can be used alone or in combination with other methods such as oral nutritional supplements and enteral nutrition.
One of the most recent resources in this area is found at www.malnutritionpathway.co.uk. 'Managing Adult Malnutrition in the Community’ is a practical guide to help identify, treat and prevent malnutrition in community settings. Developed by a multi-professional team it is supported/endorsed by ten key professional organisations including BAPEN. The document is based on clinical experience and evidence alongside accepted best practice and includes a pathway to assist in the appropriate use of oral nutritional supplements. Patient materials, a poster for use in general practice, care plans and an app as well as specific information for dietitians, GPs, nurses, speech and language therapists, patients and carers are also available via the website.
Carers UK have teamed up with Nutricia to produce information for carers and to help provide better support for carers around nutritional problems and eating difficulties. Please click here for information on Eating well for carers, Improving nutritional intake for the person you care for, Signs of a problem and Dementia and nutrition.
