How long should you store food and supplies for? There is really no right or wrong answer to this question. It is completely up to you.
To know how much you need for how long, you need to take into account the size of your family, as well as how much food and supplies they use on average each week.
HOW MUCH DOES A PERSON NEED TO EAT EVERY DAY?
On average, a man will need about twenty-five hundred calories per day. The average woman will need about two thousand. For children, the number varies by age.
Your average six to twelve year old needs a minimum of sixteen hundred calories a day. Meanwhile, a child that has reached puberty can need anywhere from twenty-five hundred to three thousand calories.
Drink half your body weight number in ounces every day. So, if you weigh one hundred pounds, you should be drinking fifty ounces of water every day.
