Correlation between proportion of dietary zinc received from animal-source foods and risk of new zinc deficiency in response to elevated [CO2]
Data are derived from analysis of food balance sheets. Percentage of dietary zinc availability from animal-source foods was calculated by dividing amount of per-capita daily bioavailable zinc from animal-source foods by total per-capita daily bioavailable zinc estimates. The percentage increase in risk of zinc deficiency was calculated as described in the Methods section of this manuscript. Zinc content in animal-source foods is assumed to remain unchanged.
