Food to "stay alive"

On Provident Living, it talks about longer term storage of food. It says:

"For longer-term needs, and where permitted, gradually build a supply of food that will last a long time and that you can use to stay alive, such as wheat, white rice, and beans."

The words "stay alive" intrigue me. Could it just be the foods recommended will help us stay alive and live healthier than any other foods? Will they help us stave off disease? To me the Lord has spoken twice -- "Nevertheless, wheat for man" in 1833 and today in his direction through our Prophet and those who serve with him. There's more to this than meets the eye. We don't want to hear -- we don't want to eat the basics because we don't know how -- we have too much of the world's "good" food and LIKE IT! Ahhhhh --- it might be time to make a choice --- follow the Lord (the arm of God) or follow the world (the arm of flesh).
