The NIOSH handbook lists sensitizing dermatitis, allergic asthma, pneumonitis, nasal cavities, and cancer as the consequences of nickel exposure. One has to wonder why, when the “US” government knows about nickel's dangers, that the FDA requires that our foods, pharmaceuticals, and beverages be processed in carcinogenic stainless steel.
Of course, it has been estimated that the FDA gets about $800,000,000 for each new drug application from the “PharMedceutical” industries to treat the “symptoms” of “dys”eases caused by metal toxicity and malnutrition. PharMedgeddon anyone?
