Rice, a staple food for a large portion of the world population, has been documented to have been cultivated, grown, and consumed for thousands of years. For those living around the Jinzu river in Toyama Prefecture in Japan in the early 1900s, rice and water consumption caused a pollution disease called “Itai-Itai disease”. Bone and join pains and kidney disease were ever increasing around this region of Japan, and it wasn’t until the 1950s that cadmium was suspected as the primary culprit.
