It is filled with sugar, salt, and soy. I wouldn't make a habit of eating this and sitting in front of a computer all day. In a disaster it wouldn't matter. I've seen mixed reviews on the flavor. Most people were okay with it and said it was filling. Other people really loved it. If you don't have a fire source you can make it with cold water but it takes longer. Only real negative I can think of is you need water to make it. Sometimes water is scarce.
