How much does one astronaut eat each day?

An astronaut typically consumes about 3,000 to 3,500 calories per day while in space, depending on their activity level. Their diet is carefully planned to include a balance of nutrients and is often packaged in vacuum-sealed containers or freeze-dried for convenience. Meals may include a variety of foods, such as fruits, nuts, and protein sources, to maintain their health and energy levels during missions.
