Background: Cadmium is a dangerous and toxic metal in the environment and is found in the earth's shell. This element has a negative impact on different tissues. The aim of the present study was to review the amount of Cadmium in foods and its effect on human health and providing preventive strategies.

Materials and Methods: This review was done by a non-systematic search of the available databases (e.g. Google search engine).

Results: Findings reveal that Cadmium is found in earth shell and sea water, and exposure to it results in some diseases and sterility.

Conclusion: Having a Cadmium-free regimen can prevent the disease or its progression. Fruits and vegetables grown in cultivating lands near the Zinc mines and contaminated with Cadmium, may cause diseases like cancer. Moreover, the fish bred in contaminated sea also can be poisonous for human.
