A hundred years ago, zinc was abundant in many soils. Nowadays, most soils in the world are zinc deficient, except for soils predominantly from biodynamic farms. This means that, where once fruit and vegetables, and even grain-based foods such as breads and cereals, provided us with a small, steady top-up of zinc, the zinc levels in many of the foods we eat today are inadequate to avoid deficiency.
