The earliest ''yan'' steamer dating from about 5000 BC was unearthed in the Banpo site. In the lower

Advantages

Most steam cookers also feature a juice catchment which allows all nutrients (otherwise lost as steam) to be consumed. When other cooking techniques are used (e.g., boiling), these nutrients are generally lost, as most are discarded after cooking. Due to their health aspect (cooking without any oil), food steamers are used extensively in health-oriented diets such as '' cuisine minceur'', some raw food diets, the Okinawa diet, a macrobiotic diet, or the CRON-diet. Food steamers release less heat to the kitchen environment, therefore helping keep the kitchen cool during hot summers. Broccoli in steamer
