Food-first comfort
Hydration first, then gentle food: homemade ORS or coconut water in small frequent sips to replace fluids if stools are loose; plain, bland foods like rice, curd, banana, khichdi and dal water; curd/yoghurt to settle the gut; safe water only (boiled/bottled when travelling) and freshly cooked, hot food; avoid raw salads, cut fruit from outside, iced drinks and heavy/oily/spicy food until settled.
What to nourish
ORS/coconut water, rice, curd, banana, khichdi, dal water, safe boiled water; bland and fresh.
Never
Care at home
Travel tummy is usually short-lived and the priority is replacing fluids with ORS while eating bland foods. Safe water and freshly cooked hot food prevent most of it; watch hydration and seek care for blood, high fever or a young baby.
