Nutritional & health benefits: aids in iron absorbtion, as well as adrenaline and glucose metabolism, and improves bone strength
Like most trace elements essential to human nutrition, nickel is in a delicate dance with other trace nutrients and vitamins to
keep your system running smoothly.
If you develop a nickel allergy and you'll soon discover how prevalent the mineral is around the house as well as in the foods you eat. The most common adverse reaction to nickel sensitivity is a skin rash at the site of contact with jewelry that contains nickel. Others may develop dermatitis or eczema.
Asthma attacks have even been reported in those with an extreme sensitivity to the metal found in jewelry or after eating high-nickel foods, such as nuts and chocolate.
Since the body needs such small amounts, nickel deficiency is rare. Nickel overdoses are also very infrequent, although studies show that overexposure to the metal is most prevalent in people involved in nickel mining or processing. For example, large doses of nickel-containing dust absorbed through the nose or mouth may lead to very serious conditions such as bronchitis and even lung cancer.
