As we celebrate ‘Nutrition and Hydration Week’ 2026, it is an opportunity to focus on two aspects of care that are often seen as distinct. Yet for older adults living in care homes, they are inseparable. Nutrition and hydration profoundly influence each other, hydration is not simply a comfort measure, it is a clinical and nutritional foundation. When nutrition declines, hydration becomes harder to maintain. Recognising this relationship and supporting residents with both aspects of care promotes good health and wellbeing and ensures care homes are delivering a person‑centred approach to care.
Hydration & Nutrition
A resident’s hydration status can significantly affect their ability to eat well. Even mild dehydration can impair alertness, mood, appetite and motivation to engage with food. Evidence shows that dehydration of 1–2% body mass can lead to confusion, lack of concentration and tiredness, all of which can directly influence mealtime engagement1,2.
The Malnutrition Task Force highlights that loss of appetite is common in older people, and hydration is a key modifiable factor underpinning appetite regulation and eating behaviour3,4. When a resident is “not eating well”, their hydration status should always be part of the clinical review.
Hydration can also affect the mechanics of eating, as an adequate fluid intake supports:
- Saliva production — essential for chewing and swallowing
- Bolus formation
- Gastric emptying
- Comfort during meals
Without sufficient hydration, residents may associate eating with discomfort, reflux, dry mouth or fatigue, all of which reduce food intake. Mouth dryness and constipation have both been linked to mealtime decline, both of which can be linked to poor hydration 5,6.
In terms of an adequate fluid intake, older adults are advised to drink 7:
-Women at least 1600ml/day
-Men at least 2000ml/day
All fluids count, water, tea, coffee, juice, squash, fizzy drinks, milk drinks7.
Many care home residents have increased needs, such as if they have a fever, diarrhoea, excessive sweating, high‑output stomas, or use of certain medications. Care plans must therefore adjust these targets and include clinical oversight.
Nutrition & Hydration
Nutritional intake can also significantly contribute to overall hydration. Fluid‑rich foods such as soups, yoghurts, ice-lollies, jelly, ice cream and fruits can help meet hydration needs, especially for residents who struggle to drink enough 2.
Malnutrition can also influence hydration. A loss of muscle mass reduces the body’s total water reserves, meaning that older adults with low muscle mass are more vulnerable to fluid depletion. Malnutrition risk assessment can also be dependent on hydration status as body weight, functional status and clinical observations can all be distorted by dehydration1.
It is therefore important for care home staff to consider nutritional and hydration status together and not in isolation. If a resident is at risk of malnutrition, fortified drinks such as milkshakes or milky tea/coffee can help to hydrate while also providing energy and protein 2,7.
Shared Barriers
Nutrition and hydration share many of the same barriers 2,5, 6,8-10. Recognising the joint impact and addressing nutrition and hydration together will improve the resident’s overall wellbeing.
| Shared Barrier | Impact on Hydration | Impact on Nutrition |
| Cognitive impairment (dementia) | Forgets to drink; unable to recognise thirst | Forgets meals; reduced hunger cues |
| Frailty & poor mobility | Unable to access drinks | Cannot access or engage in mealtimes |
| Poor dentition
|
Avoids some drinks | Avoids certain foods |
| Fear of incontinence | Deliberately restricts fluids | May skip meals to reduce toileting |
| Low mood/social withdrawal
|
Reduced drinking | Reduced eating |
| Pain or acute illness
|
Reduced thirst | Loss of appetite |
| Poor mealtime environment
|
Drinks less | Eats less |
| Swallowing difficulties
|
Unsafe or difficult drinking | Unsafe or difficult eating |
Practical Strategies to address Nutrition and Hydration
The Care Quality Commission (CQC) Regulations 9 and 14 instruct providers to integrate preferences, needs, risks and cultural considerations across hydration and nutrition planning 11. Some practical suggestions that can help with this include:
- Document food and drink preferences together, highlighting specific dietary requirements that can impact on drinks also (e.g. milk allergy and need to avoid milk-based drinks)
- Use foods that hydrate and nourish such as custard; yoghurts; milk shakes; milky drinks; smoothies; nourishing / fortified soups
- Creating enjoyable and social opportunities such as hydration cafés, mocktail clubs and “drink of the day” to encourage both drinking and social eating.
- Ensure residents with impaired mobility or co-ordination can access their meal and drink, if required adaptive equipment (handled mugs, cups with lids) can aid independence and intake.
- Mealtimes provide built‑in structure and familiarity, making them ideal for hydration support, offering drinks before, with and after meals. Drinking during mealtimes, can improve hydration and digestion and importantly make the meal much more enjoyable.
Dysphagia
For residents with swallowing difficulties, the hydration and nutrition relationship needs to be managed with care. Expert input is often required from healthcare professionals such as a Speech & Language Therapist and Dietitian.
Modified diets and thickened fluids should be prepared in line with standardised dysphagia guidance and testing methods (IDDSI, www.iddsi.org). As thickened drinks can be less appealing and take more effort to consume, residents with dysphagia can be at a higher risk of dehydration 2,12. Effective dysphagia management should consider:
- Ensure the correct consistency to keep residents safe
- Increase the frequency of offering fluids
- Monitor hydration and nutrition closely, using tools such as food and fluid charts
Recognising the link between nutrition and hydration can transform care home practice. It ensures these two essential aspects of care are prioritised together, providing an environment where residents health and wellbeing can thrive, and mealtimes can be enjoyed.
