Cadmium Toxicity MAFIADOC.COM

Cadmium toxicity is increasing in incidence today for several reasons. One of the primary reasons is a zinc deficiency in many commonly eaten foods. Zinc, which is protective against cadmium, is becoming increasingly deficient in the soil and consequently in foods. Food processing and eating of refined foods further reduces zinc intake.
