How has food changed over the last 50 years that austronauts eat?

Over the last 50 years, food for astronauts has evolved significantly, transitioning from primarily freeze-dried and canned meals to more diverse and nutritious options. Advances in packaging and preservation techniques have allowed for fresher and more varied foods, including fruits, whole grains, and even ready-to-eat meals that require minimal preparation. Additionally, there has been a focus on enhancing the taste and nutritional content to better support astronauts' health during long missions. Innovations like 3D food printing are also being explored to create meals that meet specific dietary needs and preferences in space.
