Zinc Absorption From Biofortified Rice

Bioavailability of Zinc From Rice Biofortified With 70Zn and Rice Extrinsically Labeled With 70Zn in Young Adults: a Randomized, Single-blind Study

One of the newest strategies to combat micronutrient deficiencies is the biofortification of staple foods, where higher levels of minerals are obtained through breeding of staple crops. The aim of this study is to evaluate zinc absorption from a rice biofortified with zinc when compared with a control rice fortified with zinc just before consumption.
