Nickel toxicity

Nickel is a known carcinogen. When in the diet in toxic amounts it contributes to oxidative stress, just as mercury and cadmium do, by reducing glutathione thereby interfering with cell membrane integrity and increasing lipid peroxidation (1). The oxidative damage, like from free iron or copper, can cause DNA damage (2).
