A staple around the world, white rice is widely used in almost all cuisines. Uses for rice are diverse, from being a humble sidedish to being turned into noodles, to accompanying dishes like curries and stirfrys.
Rice is not overly nutrient-dense, but does have a decent collection of minerals like manganese, thiuamin and selenium. It's mostly eaten for its contribution to energy intake, but due to its high glycemic index has been linked to increase risks of diabetes, so it's recommended to use whole grains where possible.
