It'd be interesting to see if anyone could look at this from a more "business" point of view, basically investing money up front for a better quality diet for less cost over the long term. For instance, buying seeds and growing veg, herbs, etc. Even buying 2-3 chickens and keeping them in your garden for eggs and perhaps meat. It'd be interesting to see what kind of investment would be needed, what the running cost would be and how long before you got a 100% ROI back.
