When you are choosing food for your 72 hour kit think FAST and EASY and LIGHT. What can you choose that doesn't require too much work? What can you choose that just needs to be opened and it is ready to eat? Try to choose foods that don't need to have water added to them. Remember that if you choose to pack canned foods in your 72 hour kits you will also need a can opener (for each kit). Remember to pack eating utensils to go along with that food.
When it comes to actually packing your food into your kits, zip lock bags can be very useful. Use a large freezer size to pack one day's worth of food and snacks into. If you want to take it a step further type or write out a daily menu to go into each bag. This could be very helpful in a real emergency for rationing out your food. It could also be very helpful if family members become separated in an emergency.
Finally, don't forget dessert. In case of an emergency any little treat will be greatly appreciated. Hard candies and lollipops have a very long shelf life and are small and lite to pack.
