What types of special foods do astronauts need in space?

Astronauts require specially designed foods that are lightweight, compact, and have a long shelf life to withstand the conditions of space travel. These foods are often packaged in vacuum-sealed containers or pouches to prevent spoilage and to minimize waste. Additionally, they need to provide balanced nutrition, including adequate calories, vitamins, and minerals, to support the physical demands of living and working in a microgravity environment. Some foods are also fortified with extra nutrients to counteract the effects of space on bone and muscle health.
