28. Staple food crops from Brazilian Biofortification Program have high protein quality and hypoglycemic action in Wistar rats
Abstract Biofortified staple food crops have become an effective tool by which to address micronutrient deficiencies in many at-risk populations. The effect of these food crops on the micronutrient status has been evaluated, however there is no studies investigating their protein quality, neither by themselves or in a food combination. Thus, this study inves
