What Should I Eat After Food Poisoning?
Quick answer: Rest your gut for the first few hours, then rehydrate with clear fluids and gradually reintroduce bland, easy-to-digest foods. Avoid dairy, fatty foods, and spicy foods until fully recovered.
What to Eat
Clear fluids first (water, clear broth, diluted juice)
Rehydration is the priority — food poisoning causes rapid fluid and electrolyte loss.
Oral rehydration solution (ORS)
Contains balanced glucose and electrolytes — more effective than water alone for replacing losses.
Bland carbs — toast, plain crackers, white rice
Easy to digest and help absorb excess fluid in the gut; reduces urgency and discomfort.
Bananas
Soluble fibre firms stools; potassium replaces electrolytes lost in vomiting and diarrhoea.
Plain boiled potatoes
Low-fat, bland, easily digested and provide energy without stressing the gut.
Applesauce (unsweetened)
Pectin fibre helps slow diarrhoea; very gentle on an irritated digestive tract.
Plain chicken broth or miso soup
Replaces sodium lost through illness; easy to stomach when solid food still feels impossible.
Ginger tea
Reduces nausea; anti-inflammatory compounds calm gut irritation.
What to Avoid
Dairy products (milk, cheese, yogurt)
Temporary lactase deficiency common post-infection means lactose causes bloating and worsens diarrhoea.
Fatty and fried foods
Slow digestion and increase gut stress — triggers cramping and urgency.
Spicy foods
Irritate an already inflamed gut lining; worsen cramping.
Alcohol
Dehydrates and irritates the gut; delays recovery.
Caffeine
Stimulates gut motility — worsens diarrhoea.
High-fibre foods (raw vegetables, whole grains)
Good normally but too stimulating for a recovering gut — return to these once symptoms resolve.
Sugary foods and juices
High sugar draws water into the gut, potentially worsening diarrhoea.
Hydration
This is the critical priority. If vomiting prevents drinking, take small sips every 5–10 minutes. Oral rehydration solution (sachets from pharmacy) is ideal. Sports drinks are acceptable but dilute them 50:50 with water. Stay off alcohol and caffeine until fully recovered.
Tips
- •The first phase (0–4 hours): nothing by mouth if vomiting actively — just sip water in tiny amounts.
- •Phase 2 (4–12 hours): ORS, clear broth, ice chips, diluted juice.
- •Phase 3 (12–24 hours): BRAT diet (Bananas, Rice, Applesauce, Toast).
- •Phase 4 (24–72 hours): Gradually add plain cooked chicken, boiled potato, plain soup.
- •Seek medical help if: symptoms last more than 3 days, there's blood in stool/vomit, high fever (>38.5°C), or signs of severe dehydration (no urination for 8+ hours, dizziness on standing).
