Do things cook faster with the lid on or off?
Food generally cooks faster when covered since the lid prevents energy loss. Also, food produces steam while cooking, which will circulate inside the pot with the lid on, and contribute to the food cooking more quickly.
Does covering lid cook faster?
That steam is hot, and that heat goes out of your kitchen exhaust as waste. But when you put a lid on, the heat stays in the pot. It helps cook your food faster. Less time cooking results in less energy used.

Does heat destroy vitamin D?
Vitamin D is stable and unaffected by heat. Minerals act differently in water and oil, too. What it all boils down to is that those nutrients that are not destroyed by the heat of the water, the way vitamin C is, are retained in the water. It’s a good idea to save the water for use in gravies and soups.
Which vitamin is destroyed during heating?
Vitamin C is a water-soluble and temperature-sensitive vitamin, so is easily degraded during cooking, and elevated temperatures and long cooking times have been found to cause particularly severe losses of vitamin C [12].
