While white rice may not be extremely packed with nutrition, it is a very good things to have in storage. It will store for 20 years if packed and stored in airtight containers and in a cool dry place.
I like to have rice because it easily blends with other things adapting to their flavor. It can be extremely versatile for any meal and adapts well to both sweet and savory. It can also be one of the best things tolerated by a sick or upset stomach. This may be a blessing in the event you don’t hae access to all the resources you are used to.
Brown rice does not store for long periods of time. The germ in it goes rancid fast. If you have brown rice that has a rancid smell you can rinse it under hot water while rubbing it, and it may take away some of the oils so you can still use it, but it is best to use and rotate brown rice within a year.
