Quinoa is a grain that can be used as an alternative to rice or cous-cous, and is cooked in a similar way. It has a low glycemic index, meaning that it releases its energy slowly and prevents the blood sugar spike associated with starchy foods such as rice. You can use quinoa in salads, with curries and you can even used flaked or puffed quinoa as a breakfast cereal! It's a versatile super-grain.
