Background: Golden Rice (GR) has been genetically engineered to be rich in β-carotene for use as a source of vitamin A.Objective: The objective was to compare the vitamin A value of β-carotene in GR and in spinach with that of pure β-carotene in oil when consumed by children.Design: Children (n = 68...
