NICKEL ALLERGY HOW SHOULD WE EAT

Nickel is a metal present almost everywhere: in the ground, in the air, in water. It is largely used for the production of stainless steel from which derive therefrom miscellaneous equipment, pans and doors etc. Nickel is present also in the colourants for glass objects, in hair dyes and cosmetics. Many foods contain nickel, and because some are particularly rich and also because it is transmitted from the containers in which they are stored.

The content of nickel in plants is four times higher than that of animal products and is strongly influenced by the concentrations of the metal in the soil, it varies from place to place with an increase of the concentration in spring and autumn.

Nickel is the most frequent cause of allergy to metals; It produces allergic dermatitis through contact. The hands are the areas most commonly affected for the systemic nickel dermatititis.

The allergy to Nickel manisfests itself in different ways:

  • Some people contract dermatitis even after brief contact with objects containing nickel, while others develop the allergy only after many years of contact.
  • Some people develop eczema, often many years after the primary sensitisation. May be due to the continuous contact with detergents, coins and other objects that contain nickel.

For those who are allergic to nickel it becomes complicated even to eat, hence lets take a look at the general recommendations:
