We are always conversing about our food or anything related to food in this blog. I was watching a documentary about manned space missions, when this thought about diet of astronauts popped in my mind. It is much researched and curated diet. I found it very interesting and thought of sharing it with petpuja dot com readers.
The diet of an astronaut depends on several factors, such as the duration and purpose of the space mission, the available resources and equipment, and the individual preferences and dietary restrictions of the crew members. In general, the diet of astronauts is carefully planned and designed to meet their nutritional needs while minimizing the risk of food-related problems such as spoilage, contamination, or digestive issues.
Some of the key features of the diet of astronauts include:
High Nutrient Density: Space food needs to be highly nutritious and provide adequate amounts of calories, protein, carbohydrates, vitamins, and minerals to support the physical and mental demands of space travel.
Long Shelf Life: Since space missions can last for several months or years, space food needs to have a long shelf life and be resistant to spoilage, bacteria, and radiation.
Variety: Astronauts require a diverse diet to maintain their appetite and mental health during extended space missions. The diet includes various types of food such as fresh fruits and vegetables, protein-rich foods, and snacks.
Easy to Prepare and Consume: In zero gravity, it can be challenging to prepare and consume food. Therefore, space food is designed to be easy to prepare and consume, often requiring minimal preparation or heating.
Hygiene: Hygiene is a critical factor in space food preparation, as food contamination could cause illness and jeopardize the mission. Astronauts are trained to follow strict hygiene protocols, such as washing their hands and disinfecting surfaces before handling food.
Some examples of space food include dehydrated or freeze-dried fruits, vegetables, and meats, canned or vacuum-sealed food, and food packaged in sealed containers or tubes. Additionally, astronauts may use supplements or fortified foods to meet their nutritional needs, such as vitamin D or calcium-enriched foods
The evolution of astronaut food in space has been significant since the early days of space exploration. In the early missions, astronauts were limited to eating bite-sized, freeze-dried foods that were packaged in aluminium tubes or vacuum-sealed pouches. These foods were often unappetizing and lacked variety, and astronauts frequently reported experiencing a loss of appetite.
Over time, advances in food technology and engineering have enabled significant improvements in the quality and variety of space food. Here are some key milestones in the evolution of astronaut food:
Mercury and Gemini Missions (1961-1966): Astronauts on the early Mercury and Gemini missions were provided with bite-sized, freeze-dried foods such as beef cubes, chicken and vegetables, as well as fruit and nut bars, and other snacks.
Apollo Missions (1969-1972): During the Apollo missions, astronauts were provided with an improved diet that included more varied and appetizing foods, such as shrimp cocktails, bacon squares, and chicken fajitas. They also had access to hot water and a portion of food warmer to heat their meals.
Skylab Missions (1973-1974): The Skylab missions introduced the first space-based kitchen and dining area, where astronauts could prepare and eat meals together. The menu included real bread, fresh fruit, and even coffee.
Space Shuttle Missions (1981-2011): The Space Shuttle era brought significant improvements in the quality and variety of space food, including more palatable meals, such as lasagna, spaghetti, and beef stroganoff. Astronauts also had access to a space-based refrigerator and microwave.
International Space Station (1998-present): The International Space Station (ISS) has a more sophisticated food system that provides astronauts with a wide variety of foods, including fresh fruits and vegetables grown in an onboard garden. The ISS also has a galley with an oven, microwave, and refrigerator.
Today, space food is carefully designed and prepared to meet the specific nutritional needs and taste preferences of individual astronauts, while also being lightweight, compact, and easy to store and transport. Space agencies continue to research and develop new food technologies and systems to improve the quality of astronaut food and support longer-duration space missions.

What is to be avoided in food in space?
In space, it is essential to avoid certain types of food to prevent health issues and ensure the success of the mission. Here are some examples of foods that are typically avoided in space:
Crumbly and Loose Foods: Crumbs and loose food particles can float around and get into sensitive equipment, causing damage or creating a fire hazard. Therefore, astronauts typically avoid foods that are crumbly or produce loose particles, such as bread, crackers, or cookies.
Foods with Strong Odours: In the closed environment of a spacecraft, strong odours can become overwhelming and interfere with the mission. Therefore, astronauts typically avoid foods with strong odours, such as garlic, onions, or spicy foods.
Carbonated Beverages: Carbonated beverages can produce gas bubbles in the stomach and cause bloating and discomfort. Therefore, astronauts typically avoid carbonated beverages in space.
High-Fat or High-Sugar Foods: High-fat or high-sugar foods can cause digestive problems and increase the risk of obesity and other health issues. Therefore, astronauts typically avoid foods that are high in fat or sugar, such as fast food, candy, or fried foods.
Fresh Produce with Short Shelf Life: Fresh produce such as fruits and vegetables have a short shelf life and can spoil quickly in space. Therefore, astronauts typically consume canned, dehydrated, or freeze-dried fruits and vegetables to ensure a longer shelf life and reduce the risk of spoilage.
Food with High Water Content: In the microgravity environment of space, liquids tend to form into spherical droplets that can float around and cause equipment damage. Therefore, astronauts typically avoid foods with high water content, such as watermelon or soup, or consume them in a thickened form.
So, it is lots of sacrifice of fresh and healthy food up above in the sky. food is fun only here on our earth.. our beautiful blue planet. Let us count our blessings and take care of mother nature and live a sustainable life.
Leaving you with lots of good thoughts!

This was totally new. I had never thought of this, in fact.
