Parboiling Reduces Arsenic and Preserves Nutrients in Rice
Arsenic is a naturally occurring element found in varying degrees in all soils and water, meaning that some foods, like rice, naturally contain low levels of arsenic depending on where and how it’s grown. Luckily, certain cooking and processing methods can dramatically decrease the level of arsenic rice. In this study, researchers found that parboiling your brown rice can remove up to 54% of unwanted heavy metals like arsenic from your rice (outperforming soaking or rinsing), and can also preserve important micronutrients such as zinc. You can achieve this at home by boiling your rice for 5 minutes and setting it aside for when you’re ready to cook it. You can also buy parboiled rice at the store.
