With reference to endogenous nickel contact dermatitis, the quantity of nickel resorbed is dependent on the individual capacity for absorption, the element species of nickel in the food matrix and the total nickel content in the food. As the content of nickel varies widely in individual foods, it is difficult to make any definite dietary recommendations. The wide fluctuation in the nickel content of vegetable food stuffs is due to variations in the composition of soil. This means the availability of nickel to plants is not constant. The fluctuating content of nickel in the soil also has a heavy influence. Nickel contamination can be considerable when food is prepared in the usual way. The danger of nickel contamination during industrial preparation of food has not yet been fully explored. In tests for endogenous nickel contact eczema, organic nickel should be used. Another way is to administer a diet containing only defined minute amounts of nickel.
关于内源性镍接触性皮炎，吸收的镍量取决于个体的吸收能力、食物基质中镍的元素种类以及食物中的总镍含量。由于不同食物中镍的含量差异很大，因此很难给出明确的饮食建议。植物性食物中镍含量的大幅波动是由于土壤成分的变化。这意味着植物可获取的镍并非恒定不变。土壤中镍含量的波动也有很大影响。按常规方式制备食物时，镍污染可能相当严重。食品工业制备过程中镍污染的风险尚未得到充分研究。在内源性镍接触性湿疹的检测中，应使用有机镍。另一种方法是给予仅含特定微量镍的饮食。
