Nutrition & Feeding for ALS Patients

Amyotrophic Lateral Sclerosis (ALS) progressively weakens the muscles used for chewing, swallowing, and breathing. Maintaining adequate nutrition is one of the most important supportive measures because it helps preserve strength, slows weight loss, and can improve quality of life.

Why Nutrition Matters in ALS

• Energy demands increase as the body works harder to breathe.
• Weight loss is common and is linked with faster disease progression.
• Malnutrition can worsen fatigue, respiratory function, and overall survival.
• Proper nutrients support immune function and wound healing.

Key Nutrition Goals

1. Maintain or gently increase body weight (usually 0.5kg per month).
2. Provide calorie-dense, high-protein foods.
3. Ensure adequate vitamins and minerals, especially vitamin D, calcium, and Bcomplex.
4. Prevent aspiration by adapting food texture when needed.
5. Support hydration at least 1.52L of fluids per day, unless fluid restriction is medically indicated.

Assessing Nutritional Status

Regular evaluation by a multidisciplinary team (neurologist, dietitian, speechlanguage pathologist, and respiratory therapist) is essential.

• Weight & BMI track weekly; a drop of >5% signals a problem.
• Midupper arm circumference useful when weight measurement is difficult.
• Swallowing assessment performed by a speechlanguage pathologist.
• Blood work checks for anemia, vitamin deficiencies, electrolytes.

Dietary Strategies

1. CalorieDense Foods

Choose foods that deliver more calories per bite:

• Wholemilk dairy products, cheese, yogurt.
• Nut butters, seeds, avocado.
• Olive oil, coconut oil, butter add a tablespoon to soups or smoothies.
• Pureed meats, beans, lentils mixed with broth.
• Protein powders or mealreplacement shakes (e.g., whey, casein, soy).

2. Frequent Small Meals

Instead of three large meals, aim for 56 smaller meals and snacks spread throughout the day. This reduces fatigue and improves intake.

3. Texture Modification

When dysphagia appears, adapt the diet:

• Pureed (smooth) foods for severe swallowing difficulty.
• Moist, minced, or soft foods for mildmoderate dysphagia.
• Use thickening agents for liquids (follow label instructions).

4. Hydration

Offer fluids in the form of soups, smoothies, and flavored water. If oral intake falls below 1L/day, discuss enteral options.

When to Consider Enteral Feeding

Enteral feeding (via a tube) is recommended when:

• Weight loss exceeds 10% of baseline.
• Frequent choking or aspiration pneumonia occurs.
• Oral intake provides less than 60% of estimated energy needs.
• Swallowing study shows unsafe bolus passage.

The two common methods are:

1. Nasogastric (NG) tube shortterm, less invasive, but may be uncomfortable.
2. Percutaneous endoscopic gastrostomy (PEG) more suitable for longterm use; placement usually when forced vital capacity (FVC) >50%.

Studies show that timely PEG placement can stabilize weight and may prolong survival, especially when performed before severe respiratory decline.

Supplements & Special Considerations

• Vitamin D & Calcium 8001000IU vitamin D and 1200mg calcium daily (unless contraindicated).
• Omega3 fatty acids 12g fish oil can help with inflammation.
• Creatine evidence is mixed; discuss with the neurologist before starting.
• Monitor for constipation; increase fiber and fluid, or consider a mild osmotic laxative.
• If using a PEG, keep the site clean, change the feeding bag as instructed, and rotate formula types to avoid intolerance.

Practical Tips for Caregivers

• Offer food when the patient is most alert and rested.
• Use adaptive utensils (e.g., builtup handles, swivel spoons).
• Maintain a calm, distractionfree eating environment.
• Encourage selffeeding as long as it is safe; assist only when needed.
• Keep a food diary to track calories, protein, and fluid intake.
• Stay in touch with the dietitian for adjustments as disease progresses.
