Hefty metals are all in excess of the earth. The steak you take in will have iron and nuts will comprise zinc. Large metals are in soil, air, and drinking water. As plants developed they absorb heavy metals from the soil and water and when a human being or animal eats that plant they absorb the heavy metals also.

This is why the finest sources of iron are generally meats because some animal was taking in crops with iron its full life and has a larger focus in their meat then the vegetation.
