Nutrition Tips During and right after a disaster, it will be vital that you maintain your strength. Eat at least one well-balanced meal each day. Take in enough calories to enable you to do any necessary work. Include vitamin, mineral and protein supplements in your stockpile to assure adequate nutrition. A normally active person needs to drink at least two quarts a day.
Hot environments can double that amount.
Children, nursing mothers, and ill people will need even more. You also will need water for food preparation and hygiene. Store a total of at least one gallon per person per day. You should store at least a two-week supply of water for each family member. While the methods of disinfecting and boiling will kill most microbes in water, distillation will remove microbes that resist these methods, heavy metals, salts, and most other chemicals.
