User: how is white rice made?
Assistant: White rice is produced from brown rice.  Around the outside of the brown rice is a bran layer which is removed, and then a germ is removed.  What is left behind is a starchy composition.  During this process most of the vitamins and minerals are removed.  This is why brown rice is usually preferred as a healthier alternative to white rice.  White rice is has no nutritional value because the nutrition has been stripped from it during the production process of making white rice.
