Helicobacter pylori (H. pylori) infection is commonly associated with poor hygiene and contaminated food or water. In Singapore, where eating out is a daily routine for many, it’s crucial to be aware of how certain foods may increase the risk of acquiring or aggravating an H. pylori infection.
High-Risk Foods to Watch For
The following foods can either carry the bacteria directly or worsen stomach inflammation in those already infected:
1. Raw or Undercooked Vegetables
- Examples: lettuce, cabbage, spinach, kangkong
- Risk: May be contaminated with faecal bacteria if not washed thoroughly.
2. Unwashed Fruits
- Examples: grapes, berries, apples (especially imported)
- Risk: Can carry microbes or residues from contaminated water.
3. Raw or Undercooked Meat & Poultry
- Risk: Improper handling or undercooking allows bacteria like H. pylori or others to survive.
4. Shellfish and Seafood (Especially Raw)
- Examples: oysters, clams, sashimi
- Risk: Often consumed raw and may be exposed to infected seawater.
5. Contaminated or Unboiled Water
- Bottled water or boiled tap water is safest, especially when travelling overseas.
6. Street Food and Buffet Items
- Risk: Often stored at improper temperatures or exposed to poor hygiene.
7. Excess Sugary and Processed Foods
- Risk: Can lower immune response and make the stomach environment more favourable for H. pylori colonisation.
Foods to Avoid During an H. pylori Infection
If you’re already infected, certain foods can make symptoms worse:
- Spicy dishes (chilli crab, mala hotpot)
- Fatty, oily food (deep-fried snacks, creamy sauces)
- Caffeine (coffee, strong teas)
- Carbonated drinks
- Acidic fruits (pineapple, citrus fruits)
- Alcohol
These items irritate the gastric lining and may delay healing or increase discomfort.
What to Eat Instead
Focus on foods that help reduce inflammation, support gut health, or even suppress H. pylori:
- Probiotics (e.g. yoghurt, kefir, miso, kimchi)
- Broccoli sprouts (contain sulforaphane with anti-H. pylori activity)
- Cranberries (can block bacterial adhesion to the stomach wall)
- Honey (natural antibacterial, especially manuka honey)
- Green tea (rich in anti-inflammatory polyphenols)
- High-fibre vegetables (carrots, sweet potatoes, pumpkin)
Incorporating these into your diet may help manage the infection alongside medical treatment.
Pro Tip: Always wash fruits and vegetables thoroughly, even those marked as “ready to eat.” When dining out, avoid raw garnishes or poorly cooked meats.
