Space food is a type of food product created and processed for consumption by astronauts during missions to outer space. The food has specific requirements to provide a balanced diet and adequate nutrition for individuals working in space while being easy and safe to store, prepare and consume in the machinery-filled weightless environments of crewed spacecraft. Most space food is freeze-dried to ensure long shelf life.
Designing balanced and high-quality foods for astronauts is one of the top-priority objectives in the countries having space programs. An interdisciplinary approach engaging food industry experts, as well as healthcare workers, physiologists, and chemists, needs to be used to develop efficient and safe rations for space missions. In the outer space, the human body is exposed to significant stress factors and loads that one would normally never experience on Earth. This leads to physiological changes in all body systems and, therefore, astronauts' requirements for macro- and micronutrients differ from those people would normally be used to. Due to the recent research, substantial advances have been made in the field of providing balanced and diet ology-verified nutrition to spacecraft crews. an astronaut eating a “grandma-style pie” taken from the Earth for a holiday meal should be unaware that this pie contains high doses of antioxidants, vitamins, and minerals.

Nutrition has many important functions in space travel, from providing enough nutrients and meeting the metabolic needs of a healthy body to enhancing an individual’s emotional well-being. Nutrition also plays a key role in offsetting many negative effects of space travel, such as radiation exposure, immune deficiency, oxidative stress, and bone and muscle loss.
Space Nutritionists and Food Scientists carefully select these natural foods for astronauts during their journeys and stays in space. These specially chosen foods provide the astronauts with the necessary nourishment to thrive in the challenging space environment. Remarkably, these experts assert that with the right foods, there is no need for doctors or medicines to stay free from illnesses. The wisdom of these space experts offers valuable insights that may revolutionize how we approach nutrition and well-being, emphasizing the profound impact that proper nourishment can have on our overall health. This discovery has given rise to a revolutionary concept known as Space Nutrition. Space Nutrition foods are specially formulated by Space Nutritionists, incorporating the wisdom of this theory and food science. These innovative foods aim to support health and well-being in the unique conditions of space and beyond. To transform this concept into reality and benefit humanity, a group of highly qualified NASA Space food scientists, armed with vast knowledge and experience, joined forces to create an organization. Their mission: to design and formulate foods using space food nutrition science, not just for astronauts but for people worldwide. The vision of these space food scientists is to make these groundbreaking foods accessible to everyone on Earth. By doing so, they aim to empower people to tackle their health challenges from the core, leading to disease-free, long, and healthy lives without the need for constant visits to doctors or reliance on medication. The availability of these space foods is gradually expanding across different countries. By raising awareness about the benefits of space foods and making them easily accessible, a positive change can be brought into people's lives. To spread the knowledge about space foods, the space food scientists are initiating a movement through various educational institutes and centers. Their goal is to educate people about the tremendous potential of space foods and their positive impact on health. Countries like America, China, Japan, Dubai, India, and Bangladesh can also benefit from the establishment of space food centers. The space food scientists are welcoming individuals from different countries who are interested in learning about and engaging in business with space food nutrition. Those interested can contact the group of space food scientists to develop a Space Food Center at their own location, with full guidance and product support.
Space missions can have a significant impact on astronauts' health, including changes in bone density, muscle loss, hormonal imbalances, and immune system functioning. Developing advanced space food ensures that astronauts receive adequate nutrition to support their physical health and well-being during space travel. Proper nutrition is essential for optimal cognitive function, concentration, and performance. Space missions can be mentally and emotionally demanding (Grover et al., 2022). Advances in space food can provide options for individuals with specific dietary needs, such as vegetarian, vegan, or gluten-free diets. Ensuring the safety and longevity of space food is crucial for successful missions. Advanced packaging and preservation techniques can extend the shelf life of food, maintain its nutritional integrity, and minimize the risk of contamination or spoilage.
Space food plays a crucial role in the success of space missions by providing astronauts with the necessary nutrition to support their health, well-being, and performance in the challenging conditions of space. One important aspect to consider is the biochemical changes that occur in the human body during space missions. Microgravity and other factors in the space environment can lead to alterations in bone density, muscle activity, hormonal balance, digestion and absorption, iron metabolism, ophthalmological issues, immune response, and oxidative stress. Space food must be designed to counteract these effects and provide the necessary nutrients to support the astronauts' physiological functions. Different types of space foods have been developed to meet the specific needs of astronauts. The continuous improvement and innovation in space food technology are essential to address the challenges faced in providing nutritionally balanced meals in the unique environment of space.
