与小麦和大米相比，珍珠磨和高粱提供了廉价的能源，被世界许多地区的农村社区广泛消费。由于蔬菜和动物性食品的消费量较低，小米也是微量营养素的主要供应者，特别是对于低收入群体而言。研究小米在微量金属生物可利用含量方面的表现至关重要。使用断奶小鼠进行了研究，该小鼠为人体试验前微量金属生物利用度的初步测试提供了模型。四种等热量饮食仅在谷物类型上有所不同，即珍珠粟、高粱、小麦和大米，代表了印度国家营养监测局（NNMB）观察到的习惯饮食模式。将小鼠随机分为 4 组，每组 8 只，并单独饲养在无金属代谢笼中。第五组 8 只喂食均衡合成饮食的小鼠作为对照组。所有组均自由采食。小麦和珍珠粟组在 3 个周期（每个周期 5 天）中平均锌和铁的吸收量显着高于其他 2 个实验组（p
Pearl miller and sorghum offer a cheap source of energy compared to wheat and rice and are widely consumed by rural communities in many parts of the world. Due to the low consumption of vegetables and animal foods, millets also are the major suppliers of micronutrients especially for low-income groups. It is of prime importance to study how millets perform in terms of bioavailable contents of trace metals. Investigations were carried out using weanling mice which offer a model for the initial testing of bioavailability of trace metals before human trials. Four isocaloric diets differing only in the type of cereal, i.e pearl millet, sorghum, wheat and rice, were prepared representing habitual dietary patterns observed by National Nutrition Monitoring Bureau (NNMB) of India. Mice were allocated randomly to 4 groups of 8 mice each, and housed individually in metal free metabolic cages. A fifth group of 8 mice fed a balanced synthetic diet served as control. All the groups were fed ad libitum. The absorption of zinc and iron averaged for 3 periods of 5 days each was significantly higher for the wheat and pearl millet group than for the other 2 experimental groups (p
