Wild and cultivated fruits, leaves, nuts, seeds, spices and vegetables from southern Burkina Faso and Niamey, Niger, were analysed for their copper, iron, magnesium, manganese and zinc concentrations and compared to imported, exotic reference foods found within the study area. The species analysed covered a broad spectrum of local diet; 33 were wild and 16 were cultivated. The edible wild plants were often the highest in mineral concentrations. Five species analysed, exhibited consistently high mineral values, specifically, Adansonia digitata, Boerhavia diffusa, Cerathoteca sesamoides, Sclerocarya birrea and Xylopia sp. The latter was particularly high in zinc, an observation which suggests that there may be a solid rationale for local traditions which recommended its consumption during pregnancy and lactation. Respondents indicated that during times of drought, wild plants were not consumed in the volume they once were, due to changes of infrastructure and in famine relief programmes.
对布基纳法索南部和尼日尔尼亚美的野生和栽培水果、叶子、坚果、种子、香料及蔬菜进行了铜、铁、镁、锰和锌含量分析，并与研究区域内发现的进口外来参考食物进行了比较。所分析的物种涵盖了广泛的当地饮食种类；其中33种为野生植物，16种为栽培植物。可食用野生植物的矿物质含量往往最高。所分析的五个物种始终呈现出较高的矿物质含量，具体为猴面包树、胀果博落回、芝麻菜角胡麻、非洲李和木瓣树属植物。后者的锌含量特别高，这一观察结果表明，当地推荐在怀孕和哺乳期食用该植物的传统可能有充分的依据。受访者表示，在干旱时期，由于基础设施的变化和饥荒救济计划，野生植物的食用量不如从前。
