Nickel is a ubiquitous trace element and the commonest cause of metal allergy among the people. Nickel allergy is a chronic, recurring problem; females are affected more commonly than males. Nickel allergy may develop at any age. Once developed, it tends to persist life-long. Nickel is present in most of the dietary items and food is considered to be a major source of nickel exposure for the general population. Nickel in the diet of a nickel-sensitive person can provoke dermatitis. Careful selection of food with relatively low nickel concentration can bring a reduction in the total dietary intake of nickel per day. This can influence the outcome of the disease and can benefit the nickel sensitive patient.
镍是一种普遍存在的微量元素,也是人群中金属过敏最常见的原因。镍过敏是一个慢性、复发性问题;女性比男性更易受影响。镍过敏可在任何年龄发生。一旦发生,往往会终生持续。大多数食物中都含有镍,食物被认为是普通人群接触镍的主要来源。镍敏感者饮食中的镍会引发皮炎。谨慎选择镍含量相对较低的食物可减少每日饮食中镍的总摄入量。这会影响疾病的转归,并对镍敏感患者有益。
