Brown rice or white rice? My answer is that they both have value in your food storage for different reasons.
Brown rice of course is the whole grain and therefore many times more nutritious than white rice. Brown rice needs to be used on a regular basis and rotated to prevent the grain from going rancid due to the amount of oil found in the grain. I have heard conflicting information when it comes to shelf life. The easy answer is to store what your family will eat in a year, and to continuously rotate your stock. If your family never eats rice it may be time to add it to your diet. It is a nice vairation and increases your menu possibilities drastically!
Let's talk about white rice.
I had a very dear friend and neighbor who passed away a few years ago. She was a sixteen year old girl in Switzerland when the Nazi's invaded. Her town became the new front line of the war. The German soldiers took all of the food out of the town and nothing came through the front line to provide nourishment for those living there. She told me the horror stories of those who were starving to death. She saw many people die, some right in front of her on the town sidewalks. She and her family escaped the town and country through the wilderness.
She explained to me that one of the devastating affects of starvation is severe diarrhea. Many people died because of dehydration caused by the affects of starvation. She explained that a little white rice would have saved the lives of so many. I have never forgotten the counsel of a woman who witnessed something that most don't even realize happened.
When I consider my nutritional supply I am not only preparing for my own family, I am also preparing for the needs of others.
Another consideration is that we store so many whole grains that it is a nice change in flavor and texture to have something that is not a whole grain. We need variety in our diets!
