摘要
Micronutrient deficiencies remain unacceptably high in the diets of many impoverished communities in both developed and developing countries. However, despite declining consumption patterns, pulse crops such as lentils (Lens culinaris Medik.) can serve as important crops to fill the micronutrient gap. In the present study, three lentil cultivars grown over a 2-yr study period at two locations (Bison and Wall, SD) in the Northern Great Plains were evaluated to assess the crop's ability to meet the daily nutritional requirements of critical micronutrients: Fe, Mg, K, Se, and Zn. Results were found to vary significantly by location and by cultivar. The greatest differences were found for Se. Between cultivars, concentrations ranged from 115 to 210% of daily requirements per 100 g lentils at Bison and 295 to 381% at Wall. On the basis of average yields per hectare and nutrient concentrations, lentils were found on average to meet the yearly recommended intake requirements of 13 and 20 adult females for Fe, 9 and 13 adults for Mg, 7 and 11 adults for K, 49 and 125 adults for Se, and 14 and 26 adults for Zn between the two study sites, respectively.
