Since the 1960s, the nutritional value of space food has greatly improved from pureed meat in tubes. Astronaut food today is designed to counteract the severe physical challenges of microgravity, such as bone and muscle loss. This specialized diet is crucial for health and provides energy and specific nutrients to protect the crew.

While space itself has no calories, the human body needs a precise energy intake to survive and function in microgravity. The average astronaut consumes between 2,500 and 3,500 calories daily, depending on their workload, to address the unique physiological challenges of space travel.
