Q&A: Growing a Whole Nutrition Landscape

The question for this episode is from Geoff:  I'd love to hear your thoughts about how homestead sites can create a "whole nutrition" landscape with permaculture.  What I mean, is that a "healthy balanced diet" typically includes sources for necessary nutrients, calories, minerals, proteins, carbohydrates/starches, etc. Growing the leafy greens, berries, fruit, vegetables is all very well and good -- but if we are seeking to create a 'whole nutrition' landscape, we need to re-evaluate how much area in the gardens are devoted to tubers/roots and protein sources like nuts (hazelnuts) or seeds (sunflower, serviceberry seeds) versus the more typical perennial greens.  Ie Maybe way larger portions of the landscape should be devoted to tubers and fast-growing nuts/seeds than is typically seen in Permaculture Designs, for instance for PDC courses?!
