Deficiencies of iron and zinc among the population dependent on plant foods necessitate strategies to maximize their bioavailability. In this context, specific combinations of promoters of iron and zinc bioaccessibility-namely, amchur (0.75g/10g), beta-carotene-rich vegetables (2.5 g/10 g) and Allium spices (1.5 g/10 g)-were evaluated for a possible additive/synergistic effect on the bioaccessibility of iron and zinc from food grains. The positive influence on the bioaccessibility of iron was additive in the case of combinations of amchur-carrot, amchur-garlic, onion-carrot, and onion-amaranth in a few specific grains. Positive influence on the bioaccessibility of iron was even synergistic for combinations of amchur-onion and amchur-garlic in a few grains. The influence of amchur-garlic and amchur-onion was additive while the combination of amchur-amaranth and amchur-garlic produced a synergistic-promoting influence on zinc bioaccessibility in a few instances. This observation would be useful in evolving dietary strategies to maximize the bioavailability of minerals from grains.
