I heard that steamed vegetables are very healthy. Is it true?/You don't say.

Steaming is the earliest famous cooking method besides eating and drinking blood and barbecue. Modern nutrition science research has proved that steaming is also one of the best cooking methods. During the Xia and Shang Dynasties in China, there were cookware such as pottery retort and bronze retort, with a round tripod below and a steamer and a pot cover above, which were very close to the modern steamer.

Steaming, using water to generate steam, the cooking temperature is about100 ~10/0/degree, and food is cooked by the conduction of steam. In the autoclave or electric pressure cooker, the temperature of water vapor can reach 106 degrees, and food can be cooked easily. In plateau anoxic areas, people usually cook food in a pressure cooker, otherwise the water can be cooked to 85 degrees or even lower, and the food is not cooked at all.

Steaming can maintain the original flavor and even the shape of food to the greatest extent. It is also the main cooking method of famous dishes since ancient times, such as steamed mutton and deer tail at Manchu banquet, and many dishes that have been eaten to protect animals, such as grilled shark's fin and grilled fish lips. Ordinary steamed vegetables include steamed fish, steamed beef with flour and braised pork with plum vegetables, which are also well-known delicacies.
