Living with Allergic Bronchopulmonary Aspergillosis (ABPA), bronchiectasis, and asthma means managing chronic lung inflammation, mucus production, and allergies. While no diet can cure these, the right food choices can help support the lungs, reduce flare-ups, and boost immunity.
It is worth noting that a good balanced diet is important. The foods suggested below are to be included in addition to a good diet, not instead of one.
✅ What to Include
1. Anti-inflammatory foods
- 🍇 Berries, cherries, grapes
- 🐟 Oily fish (salmon, sardines, mackerel – omega-3)
- 🫒 Olive oil, avocado, flaxseed
- 🍵 Green tea and turmeric (with black pepper for absorption – remember to mention that you are taking any food supplement to your doctor )
2. High-antioxidant foods
- 🥦 Broccoli, spinach, kale, sweet potatoes
- 🍅 Tomatoes (rich in lycopene for lung health)
- 🧄 Garlic and onions (natural anti-inflammatories)
3. Good hydration
- 💧 Plenty of water and herbal teas to loosen mucus
- 🍲 Soups and broths can help soothe airways
4. Foods rich in vitamin D, C and zinc
- 🥚 Eggs, fortified cereals, mushrooms (vitamin D)
- 🍊 Oranges, bell peppers, kiwi (vitamin C)
- 🥜 Nuts, seeds, legumes (zinc)
❌ Foods to Avoid or Limit
1. ‘Mucus-thickening’ foods
- 🧀 Excess dairy (cheese, cream, full-fat milk) may worsen the sensation of mucus for some
- 🍬 Processed sugar (cakes, sweets, fizzy drinks) triggers inflammation
2. Common allergens
- 🌾 Wheat/gluten or dairy can worsen symptoms if you’re intolerant
- 🥜 Nuts or soy – avoid if known allergens
3. Pro-inflammatory foods
- 🍟 Fried foods, processed meats (bacon, sausages)
- 🥤 Artificial additives and preservatives
4. Alcohol and caffeine (in excess)
- Can dehydrate and irritate airways
🚫 Watch Out For:
- Mouldy or fermented foods (blue cheese, kimchi, kombucha) can contain fungi and may trigger ABPA if spores are inhaled.
- Compost or mouldy food in the kitchen – avoid exposure due to risk of inhaling fungal spores.
🔁 Bonus Tips
- Eat small meals if large ones trigger breathlessness
- Keep a food-symptom diary to spot personal triggers
- Work with a dietitian if weight loss, fatigue, or food intolerance is an issue
🚫 Foods to Avoid or Limit While Taking Aspergillosis Medications
| ⚠️ Food or Drink | ❓ Why Avoid It |
|---|---|
| Grapefruit and grapefruit juice | Blocks liver enzymes (CYP3A4), increasing drug levels dangerously (especially itraconazole, voriconazole) |
| Seville oranges (marmalade) | Same enzyme-blocking effect as grapefruit |
| High-fat meals (with voriconazole) | May reduce absorption – best taken on an empty stomach |
| Very low-acid foods (with itraconazole capsules) | Needs stomach acid to absorb – avoid taking with antacids, PPIs (e.g. omeprazole), or alkaline meals |
| Alcohol | Increases the risk of liver toxicity, especially with long-term antifungal use |
| Liquorice root (in large amounts) | May raise blood pressure and interact with the metabolism of antifungals |
| St John’s Wort (herbal) | Dramatically reduces antifungal effectiveness by speeding up liver metabolism |
| Supplements with high calcium or magnesium | Can interfere with some oral suspensions or acid levels, depending on timing |
💊 Drug-Specific Tips
| Antifungal | Take With Food? | Notes |
|---|---|---|
| Itraconazole capsules | ✅ Yes – needs acid and fat for absorption | |
| Itraconazole solution | ❌ No – better on empty stomach | |
| Voriconazole | ❌ No – take 1 hour before or 1–2 hours after food | |
| Posaconazole tablets | ✅ Yes – improved absorption with food | |
| Isavuconazole | ✅ Can be taken with or without food |
