Plate ground First episode

Rice grows underwater. While growing it absorbs some toxic metals such as mercury cadmium and mostly arsenic. In whole rice, a large amount of arsenic was found. Most of the rice's arsenic is located in the outer shell, there for it is safer to choose white rice over whole rice in order to avoid consuming a large amount of this metal. However, in white rice, a lot of vital nutrients are missing, such as fibers, vitamins and minerals. 

One should be critical about considering rice as a food, since the common dietary recommendation is of consuming whole grains.

If whole rice is one of your food sources, make sure you soak it in water, drain it, then cook it in water and drain the water, in order to reduce the amount of toxic metals as much as possible.

If you are choosing white rice, the described cooking technique still applies, and you must add the missing nutrients from other food sources.

My personal recommendation is of eating White Japanese rice : from Japan. There is no need to soak and wash this rice.
