Chesrspres shares a nice visual of a bare minimum years supply of food for one person. This is the absolute bare bones. They say with this and if you had yeast stored you could have one loaf of bread and a third of a cup of beans for your entire days food. I like this picture because it really shows how little you need for a year to JUST survive. Anything after you have that stored is extra. Nice info for beginning preppers.
