Eating at home during treatment: a familiar kitchen, new rules
Coming home from hospital is a relief, but the home kitchen also needs new rules. This section gathers practical tips on shopping, cooking, storing and the family’s role.

01Short answer
02Simple explanation
Buy sealed food.
Cook fully.
Refrigerate within 2 hours.
Leftovers: 1–2 days.
03Scientific explanation
FDA/USDA: the four main rules for preventing food-borne infection are clean, separate, cook and chill.
ESPEN: enough energy and protein matter for preventing weight and muscle loss in people with cancer, and nutritional status should be assessed regularly.
NCI: practical eating tips exist for treatment side effects such as nausea, taste changes and mouth sores.
04What happens in the body?
Shopping
Pick chilled items last and get them home quickly; do not buy damaged packs or swollen tins.

The family’s role
Everyone who cooks should know the rules; a family member who is ill should stay out of the kitchen.

Dietitian
If you are losing weight, have no appetite or need a special diet, ask to see the hospital dietitian.
Food safety
Food-safety rules for neutropenia (see “Handwashing: the simplest protection” and “Eggs and dairy: safe choices”) apply at every stage.
05Nutrition: four steps
Assess, swap the risky, cook safely, eat regularly.
