Nutrition and Huntington’s disease: supporting health and quality of life

In this article we look at key nutrition considerations for people living with Huntington’s disease, practical dietary strategies across the disease stages and why early dietetic support is essential for maintaining health, function and quality of life. 

Huntington’s disease is an inherited condition caused by a genetic mutation, leading to gradual degeneration of nerve cells in the brain. Symptoms typically begin in adulthood and progress over time, affecting physical movement, thinking and emotional regulation. 

From a nutrition perspective, Huntington’s disease can impact intake in several ways: 

• Involuntary movements (chorea) increasing energy expenditure.
• Fatigue making eating and meal preparation difficult.
• Cognitive changes affecting planning, memory and decision-making.
• Behavioural changes influencing appetite and food preferences.
• Swallowing difficulties increasing the risk of choking and aspiration. 

These challenges mean that even individuals who appear to be eating regularly may struggle to meet their nutritional needs. 

One of the most well-recognised nutrition issues in Huntington’s disease is unintentional weight loss. Research indicates that people with HD often have higher energy requirements than the general population, even in the early stages of the disease. 

Contributing factors include: 

• Constant involuntary movements.
• Altered metabolism.
• Reduced efficiency of food intake. 

If increased energy needs are not met, individuals may experience rapid weight loss, muscle wasting, reduced immunity and increased fatigue. Maintaining weight is therefore a key priority throughout all stages of Huntington’s disease. 

Regular monitoring of body weight and nutritional intake allows early identification of concerns and timely intervention. 

To support weight maintenance, many people with Huntington’s disease benefit from a high-energy, high-protein diet. This does not mean large portion sizes, but rather fortifying meals and snacks to make the most of each mouthful. 

Helpful strategies include: 

• Using full-cream dairy products.
• Adding healthy fats such as olive oil, avocado, nut butters and seeds.
• Including protein-rich foods for each meal and snack (e.g., meat, fish, eggs, dairy, legumes and tofu).
• Fortifying meals (e.g., adding peanut butter to porridge or adding milk powder and olive oil to soups). 

Small, frequent meals and snacks are often more manageable than three large meals per day, particularly when fatigue or reduced appetite is present. 

As Huntington’s disease progresses, many individuals develop dysphagia or difficulty swallowing. This increases the risk of choking, coughing during meals and aspiration pneumonia. 

Signs of swallowing difficulty may include: 

• Coughing or throat clearing when eating or drinking.
• Taking longer to finish meals.
• Avoiding certain textures.
• Frequent chest infections. 

A speech pathologist can assess swallowing safety and recommend appropriate food and fluid textures. A dietitian then works alongside them to ensure that texture-modified diets remain nutritionally adequate and enjoyable. 

Texture modification may include: 

• Soft or minced foods.
• Moist meals with added sauces.
• Thickened fluids, if required. 

Changes in mood, cognition and behaviour are common in Huntington’s disease and can significantly affect eating patterns. Some individuals may forget to eat, lose interest in food or develop rigid food preferences. 

Supportive strategies may include: 

• Establishing consistent meal and snack routines.
• Offering familiar and preferred foods.
• Reducing distractions during meals.
• Providing gentle prompts or supervision when needed. 

Education and support for carers and support workers is often essential to ensure nutrition goals are met safely and consistently. 

Fatigue and declining physical function can make shopping, cooking and eating increasingly difficult over time. Without adequate support, this may lead to skipped meals or reliance on low-nutrient foods. 

Practical supports may include: 

• Simple, high-energy meals requiring minimal preparation.
• Pre-prepared meals or meal delivery services.
• Assistance from carers or support workers.
• Adaptive equipment recommended by an occupational therapist. 

Nutrition strategies should be realistic, sustainable and aligned with the individual’s abilities and preferences. 

Maintaining adequate hydration is essential but often challenging for people with Huntington’s disease. Reduced thirst awareness, swallowing difficulties, and fatigue can all contribute to low fluid intake. 

Poor hydration can worsen: 

• Constipation.
• Fatigue.
• Confusion and irritability. 

To assist in meeting fluid requirements, dietitians may recommend: 

• High-fluid foods such as soups, yoghurt, custards and jelly.
• Flavoured fluids in addition to plain water such as tea, coffee or home-brewed iced-tea.
• TabTimer reminder cups,  this helpful tool sounds intermittently to remind you to sip fluids.
• Naturally thicker fluids such as smoothies or milkshakes. Adaptive cups and bottles. 

An Accredited Practising Dietitian is a key member of the multidisciplinary team supporting people with Huntington’s disease. Nutrition care should be individualised, proactive and reviewed regularly, as needs change over time. 

Dietetic support may include: 

• Comprehensive nutrition assessment.
• Weight and intake monitoring.
• Individualised meal and snack plans.
• Recommendations for supplements where needed.
• Education for carers and support workers.
• Collaboration with speech pathologists and medical teams. 

Early referral to a dietitian is strongly recommended,  before significant weight loss or swallowing difficulties occur. 

You may benefit from dietetic input if you or someone you support with Huntington’s disease is experiencing: 

• Unintentional weight loss.
• Difficulty chewing or swallowing.
• Reduced appetite or limited food variety.
• Fatigue impacting food intake.
• Ongoing bowel or hydration concerns.
• Altered laboratory or blood test results.  

Nutrition intervention is most effective when started early and adjusted as the condition progresses. 

If you or a loved one is living with Huntington’s disease, tailored nutrition support can play a vital role in maintaining strength, comfort and quality of life. Working with an experienced dietitian ensures nutrition strategies are safe, practical and responsive to changing needs. 

Nutrition care in Huntington’s disease is not just about food, it is about supporting dignity, independence and wellbeing at every stage of the condition.
