Food as Medicine: Dietary Approaches for 10 Common Ailments

While food cannot replace medical treatment, evidence-based dietary choices can alleviate symptoms and support recovery for many common conditions.

Headache / Migraine

• Helpful: Hydration, magnesium-rich foods (spinach, pumpkin seeds, almonds), riboflavin (eggs, dairy, lean meat), omega-3s (fatty fish), ginger. Consistent meals prevent hunger-triggered headaches.
• Avoid: Known triggers—aged cheese, cured meats (nitrates), alcohol (especially red wine), caffeine withdrawal, MSG, aspartame, dehydration.

Stomach Pain / Indigestion

• Helpful: Ginger (tea, chews), peppermint (oil/tea—avoid if GERD), chamomile tea, BRAT foods (banana, rice, applesauce, toast), small frequent meals.
• Avoid: Spicy, fried, fatty, acidic (citrus, tomato), caffeine, alcohol, carbonated drinks, large meals before bed.

Fatigue

• Helpful: Complex carbs (oats, quinoa, sweet potato), lean protein (eggs, poultry, legumes), iron-rich (spinach, lentils, beef—if deficient), B-vitamins (whole grains, nutritional yeast), hydration. Small frequent meals stabilize glucose.
• Avoid: Refined sugar (crash), excess caffeine (disrupts sleep), heavy meals, alcohol.

Constipation

• Helpful: Soluble + insoluble fiber (prunes, kiwi, chia, flax, oats, veggies), adequate fluid (2–3L), prune juice, kiwi (actinidin), regular exercise.
• Avoid: Low-fiber processed foods, excess dairy (some), unripe bananas, dehydration.

Diarrhea

• Helpful: BRAT, soluble fiber (oats, psyllium), probiotics (yogurt, kefir, supplements), electrolyte replacement (broth, ORS), cooked carrots, green banana.
• Avoid: High-fat, spicy, caffeine, alcohol, artificial sweeteners (sorbitol, mannitol), raw veggies, high-insoluble-fiber.

Nausea

• Helpful: Ginger (1–1.5g/day), peppermint (avoid GERD), small bland snacks (crackers, toast), cold foods (less aroma), lemon scent, vitamin B6 (25mg TID), acupressure (P6).
• Avoid: Greasy, spicy, strong odors, large meals, lying flat after eating.

Sore Throat

• Helpful: Warm liquids (tea + honey), honey (antimicrobial), ice pops, smoothies, yogurt, marshmallow root, slippery elm.
• Avoid: Crunchy, spicy, acidic (citrus, vinegar), very hot, alcohol.

Cough / Cold / Flu

• Helpful: Honey (1 tsp at bedtime > dextromethorphan for nocturnal cough), chicken soup (anti-inflammatory), garlic, ginger, turmeric, citrus (vitamin C), zinc lozenges (early), hydration.
• Avoid: Dairy (may thicken mucus for some), sugar, alcohol, dehydration.

Acne

• Helpful: Low-glycemic diet, omega-3s, zinc (pumpkin seeds, shellfish), antioxidants (berries, greens), probiotics.
• Avoid: High-glycemic carbs, skim milk (some), whey protein, excess saturated fat.

Insomnia

• Helpful: Tart cherry juice (melatonin), kiwi, walnuts/almonds (magnesium), chamomile, warm milk (tryptophan), complex carb + protein snack.
• Avoid: Caffeine after noon, alcohol (fragments sleep), large/spicy meals <3 hr before bed, excess fluids.

Important Caveats

• Individual responses vary; keep a food-symptom journal.
• These are adjunctive, not curative for serious conditions.
• Consult a clinician for persistent/worsening symptoms.
• Registered dietitians provide personalized medical nutrition therapy.
