Sustainable food production and food sufficiency both assume a mix of agricultural production that concentrates heavily on grains, fruits, and vegetables.
NewVistas Model

A NewVistas community will produce a sustainable mix of agricultural production that concentrates heavily on grains, fruits, and vegetables. The diet of a globally scalable community would have to reflect the same mix - although the community does not necessarily seek to produce all of its own food and does not attempt to regulate participants' eating habits.
