Most adults need around 1500 – 2500 calories per day to remain healthy. However, after an event like an earthquake, it’s likely your needs will increase as you will be doing things you wouldn’t normally have to – just keeping warm for instance uses lots of calories. It is important to have access to nutrition after an earthquake, but vital for those who are ill or young. Appreciating that it’s not always possible to have food set aside for disasters, you could perhaps make sure that the food you do have is high calorie, just in case.
Make sure that your supplies have a long shelf life, or require little or no cooking – tinned food is excellent as it is usually pre-cooked and only requires heating up (not essential). Foods such as pasta and rice keep for long periods and are high in carbohydrates which means they are loaded with energy.
It’s up to you to decide what’s important for you and your family, so make sure your food supply is appropriate.
