Susan MacMillan adds more arrows to the quiver of dietary diversification:
Let’s not forget another important if traditional weapon in our arsenal — animal agriculture, which provides poor households with modest quantities of milk and meat, which help human bodies make better use of the staples they consume, as well as help farmers not only make regular incomes but also make more efficient, sustainable and productive use of their croplands and farming systems. Indeed, the oldest staple of all may be not grains but diversification itself.
