I think this is something worth being aware of. Most people actually need very little food to live a healthy life. There are people, alive and well, who claim they eat one meal a week or a month and remain healthy. Since we have 3 basic survival needs: food, shelter, water. Minimizing our dependency on any is good knowledge to be aware of.
