4.3 Describe dietary requirements associated with common health conditions

This guide will help you answer 4.3 Describe dietary requirements associated with common health conditions.

Food plays an important part in maintaining health and managing different health conditions. Certain conditions require specific diets to support wellbeing, reduce symptoms, and prevent further complications. In this guide, we will cover some of the dietary needs linked to some common health conditions. Understanding these needs will help you provide better care.

Diabetes

Diabetes affects how the body processes glucose (sugar). It is essential for individuals with diabetes to maintain stable blood sugar levels. Diet management plays a crucial role in achieving this.

Key dietary requirements include:

• Spreading meals throughout the day to avoid spikes or drops in blood sugar.
• Eating high-fibre foods, such as whole grains, fruits, and vegetables, to help with slower glucose absorption.
• Avoiding sugary foods and drinks, which can rapidly increase blood sugar.
• Including lean protein sources like chicken, eggs, and beans to provide energy without causing a sugar rise.
• Monitoring carbohydrate intake, as carbs directly affect blood sugar levels.
• Choosing healthy fats, such as those from nuts, seeds, and avocados, rather than saturated or trans fats.

People with diabetes should also avoid skipping meals, as this can lead to hypoglycaemia (low blood sugar), a dangerous condition.

Hypertension (High Blood Pressure)

Hypertension increases the risk of heart disease and strokes. Diets for people with high blood pressure aim to lower salt intake and boost heart health.

Important dietary recommendations include:

• Reducing salt (sodium) intake to under 6g a day (about a teaspoon). This is a key factor in managing blood pressure.
• Consuming plenty of fruits and vegetables for their potassium, which helps balance the effects of sodium.
• Including oily fish, such as salmon or mackerel, twice a week for omega-3 fatty acids, which support heart health.
• Limiting processed foods, like ready meals and crisps, as these often contain high levels of hidden salt.
• Choosing low-fat or fat-free dairy products.
• Avoiding excessive alcohol consumption, which can raise blood pressure levels.

Encouraging the person to cook with herbs and spices instead of salt can help reduce reliance on sodium without losing flavour.

Coeliac Disease

Coeliac disease is an autoimmune condition where the consumption of gluten damages the small intestine. Gluten is a protein found in wheat, barley, and rye.

For someone with coeliac disease, the dietary requirements are:

• Complete exclusion of gluten-containing foods, such as bread, pasta, biscuits, and cakes made from wheat, rye, or barley.
• Choosing gluten-free alternatives, which are widely available in supermarkets.
• Being careful about cross-contamination when preparing food at home.
• Checking food labels for hidden sources of gluten, such as in sauces or processed goods.
• Including naturally gluten-free foods such as rice, potatoes, meat, fish, and fresh fruits and vegetables.

A dietician may advise individuals to take vitamin and mineral supplements if deficiencies, such as low levels of iron or calcium, are detected.

Irritable Bowel Syndrome (IBS)

IBS affects the digestive system and can cause bloating, cramping, diarrhoea, or constipation. Dietary management focuses on easing symptoms.

Common dietary strategies involve:

• Identifying and avoiding trigger foods such as caffeine, spicy foods, or fatty foods.
• Introducing a low FODMAP diet. FODMAPs are short-chain carbohydrates that can worsen IBS symptoms for some people. Examples include certain fruits, beans, and dairy products.
• Eating smaller meals more frequently to reduce strain on the digestive system.
• Increasing fibre intake gradually, especially for IBS with constipation.
• Drinking plenty of fluids, particularly water, to support digestion.

Encouraging the person to keep a food diary can help them track symptom triggers and adapt their diet accordingly.

Heart Disease

Heart disease refers to conditions affecting the heart, such as coronary artery disease. A heart-healthy diet can reduce risks and manage existing conditions.

Dietary requirements for heart health include:

• Reducing saturated and trans fats, such as those in fried foods and animal fats, to lower cholesterol levels.
• Increasing soluble fibres, found in oats, beans, and lentils, which help reduce bad cholesterol (LDL).
• Prioritising lean proteins like chicken, fish, and legumes over red and processed meats.
• Consuming oily fish for heart-friendly omega-3 fatty acids.
• Limiting refined carbohydrates and sugary foods to avoid weight gain.
• Opting for unsaturated fats, found in olive oil, nuts, and seeds.

Avoiding smoking and managing stress go hand in hand with dietary choices in preventing further heart problems.

Kidney Disease

The kidneys filter waste and excess substances from the blood. When they are not working well, diet adjustments can slow further damage.

Key considerations include:

• Reducing protein intake to lower the workload on the kidneys. Protein sources like meat and eggs should be eaten in moderation.
• Monitoring salt intake to help control blood pressure, as high blood pressure can harm the kidneys further.
• Limiting potassium-rich foods in advanced kidney disease. Examples include bananas, oranges, and potatoes.
• Reducing phosphorus, found in dairy, beans, and processed foods, as high levels can lead to bone problems.
• Drinking sufficient water but balancing it with medical advice, especially if fluid retention is an issue.

A healthcare professional should always guide kidney patients on personalised advice for their condition’s stage.

Cancer

Cancer and its treatments can impact appetite and nutritional needs. Nutrition becomes vital in maintaining strength and supporting recovery.

Common dietary adjustments include:

• Eating small, frequent meals to combat reduced appetite.
• Consuming high-protein foods, such as chicken, eggs, and fish, to repair tissues and promote healing.
• Including foods rich in vitamins and minerals, such as leafy greens and brightly coloured vegetables, to boost immunity.
• Choosing high-calorie, nutrient-dense snacks like yoghurt if there is weight loss.
• Avoiding alcohol and processed foods, which can exacerbate symptoms or interact with treatments.
• Staying hydrated, particularly when nausea or vomiting occurs.

Caregivers should seek support from dieticians to meet the complex nutritional needs cancer care can require.

Lactose Intolerance

Lactose intolerance occurs when the body cannot properly digest lactose, a sugar found in milk and dairy products.

Adjustments for lactose intolerance include:

• Avoiding milk, cheese, and other dairy products containing lactose.
• Using lactose-free alternatives, such as almond, soya, or oat milk.
• Including calcium-rich, non-dairy sources like leafy greens, tofu, and fortified plant-based milk.
• Checking food labels for hidden lactose in products such as bread and ready meals.

If the person has trouble meeting their calcium and vitamin D needs, supplements may help prevent deficiencies.

Obesity

Obesity increases the risk of various health conditions, including diabetes, heart disease, and joint issues. A weight-loss-focused diet promotes gradual, sustainable changes.

Guidelines often recommend:

• Reducing calorie intake, especially from processed and high-sugar foods.
• Prioritising whole, nutrient-dense foods like vegetables, whole grains, and lean proteins.
• Avoiding sugary drinks and alcohol, which are high in calories.
• Practising portion control to avoid overeating.
• Eating mindfully to recognise hunger and fullness cues.

Exercise, alongside a balanced eating plan, aids weight-loss efforts and overall health.

Allergies

Food allergies trigger immune system reactions to specific proteins, which can cause mild to severe symptoms.

Key dietary adjustments include:

• Identifying and completely avoiding the allergen, such as nuts, shellfish, or dairy.
• Reading food labels carefully to check for allergens, which are highlighted under UK law.
• Being cautious about cross-contamination, especially when eating out.

For severe allergies, having an emergency plan, such as carrying an EpiPen (adrenaline injector), is vital.

Final Thoughts

Different health conditions require adjusted diets to support individuals’ wellbeing. By understanding these specific needs, care workers can provide better support and make meal times safer and more enjoyable. Guidance from dieticians and healthcare professionals is often necessary to set appropriate nutritional plans.
