You must have read, heard a story or even watched a movie where people survived a catastrophe by simply storing food for emergency purposes. Well, that is not something imaginable. It is something real and something that can be done. When you store food, for example, 7-day emergency food supply that consists of dried food, packed food, and any other non-perishable food reserve, you can have something to eat for an entire week.
When you hear of the 7-day emergency food supply, the first thing that comes into your mind is the huge amount of food you will have to store. Well, it can be bulky but it is important because it is what you need. You can reduce the bulkiness by drying the food. For example, vegetables can be dried and used later. Cereals are also great and can be stored for long periods of time and used as food.
For those who are preparing for long trips or cruises, having adequate 7-day emergency food supply is essential. However, this depends on the number of people on board or you are traveling with. The bigger the number the more food you will need to store. You need to plan adequately and learn how to use the food minimally.
