ALS Nutrition: What to Eat and Avoid to Support Muscle and Swallowing Function

When someone has amyotrophic lateral sclerosis, a progressive neurological disease that breaks down motor neurons, leading to muscle weakness and loss of movement. Also known as Lou Gehrig's disease, it slowly steals the ability to chew, swallow, and breathe—making nutrition one of the most critical, yet overlooked, parts of care. Unlike other conditions where weight loss is a side effect, in ALS, losing weight isn’t just about feeling weak—it’s linked to faster decline and shorter survival. What you eat directly affects how long you can stay independent, how often you get sick, and whether you can avoid feeding tubes.

Swallowing difficulties, a common and dangerous symptom in ALS caused by weakened throat muscles turn simple meals into risks. Thin liquids like water or coffee can slip into the lungs, causing pneumonia—the leading cause of death in ALS. Thickened drinks, pureed foods, and soft textures become necessary long before people realize it. Muscle wasting, the loss of lean body mass due to nerve damage and reduced activity means your body burns calories faster, even at rest. Without enough protein and calories, your body starts eating its own muscles to survive. That’s why high-calorie, high-protein meals aren’t a luxury—they’re a medical necessity.

Many people with ALS focus on avoiding sugar or cutting carbs, but those rules don’t apply here. You need dense nutrition: peanut butter, whole milk, cheese, eggs, ground meats, smoothies with protein powder, and olive oil drizzled on everything. Ice cream and milkshakes aren’t treats—they’re tools. If swallowing gets harder, a speech therapist can guide you on texture modifications. If eating takes too long or you tire out, a feeding tube isn’t giving up—it’s buying time to stay active and alert. The goal isn’t to eat perfectly. It’s to eat enough to keep your body from turning against itself.

What you avoid matters too. Crunchy, dry, or sticky foods like nuts, raw veggies, toast, and caramel can get stuck and cause choking. Alcohol and caffeine dry out your mouth, making swallowing harder. Large meals can overwhelm your system—smaller, more frequent meals work better. And don’t wait until you’re losing weight to act. Start adjusting your diet early, even if you feel fine. The body adapts slowly, but the decline doesn’t.

Below, you’ll find real, practical advice from people who’ve walked this path—how to make meals safer, how to track calories when appetite fades, what supplements actually help, and when to talk to a dietitian about tube feeding. These aren’t theories. They’re the strategies that keep people alive, comfortable, and in control longer.
