While nutrition and health are important in space travel, the physics of eating in a zero gravity environment presents some unique challenges. Any food that requires chewing and swallowing, such as sandwich bread or regular fruits and vegetables, can float away or be difficult to swallow without the simulation of gravity.
In addition, the crumbs of food items like bread and crackers can float and interfere with sensitive equipment. Therefore, the types of food that astronauts can eat in space are limited.
Space limit the consumption of many refrigerator and freezer staples, such as eggs, most dairy products, and ice cream. The reduced gravity is also an issue for carbonated beverages, as the gas can form large, unmanageable bubbles.
Foods that are vacuum sealed,/dried, or pasteurized are better suited to space travel and are served to the astronauts aboard the International Space Station. Examples of these types of food items include dried, pre-cooked chicken, beef, fish and fruit, and freeze dried ice cream, peanut butter, and other condiments.
Astronauts also get their nutrition from supplements, such as protein and vitamin bars, fruit juices, and reconstituted foods.

What are you not allowed to eat in space?
In space, you are not allowed to eat regular food due to the lack of proper storage and protection from spills and contamination. Astronauts have to consume food that has been specially packaged for space consumption.
The space food comes in the form of bite-size cubes and packages, often containing dried fruits and nuts, rehydrated meats, mashed potatoes, tortillas, and other similar items. These items are carefully sealed and vacuum-sealed to prevent dehydration and microbial growth.
They are easy to consume in the zero gravity of space, with minimal waste. MREs (meals-ready-to-eat) are also eaten on long missions, although these often have to be dispatched from Earth and can be of lower quality.
In addition, it is important to note that many of the beverages that are available in space are different than those available on Earth. The most common beverage consumed in space is reconstituted fruit juices, such as orange and grapefruit juices, as well as water.
Carbonated drinks are prohibited due to the risk of contamination and foaming, which can be problematic in zero-gravity. Coffee, tea, and hot chocolate are also available in special packages, and most astronauts like to add a small packet of sugar if desired.
What is forbidden in space?
The laws of physics still apply in space, so it is forbidden to do many of the same activities that are forbidden here on Earth. In general, most activities that are illegal in Earth’s atmosphere are also illegal in space.
These include activities that may pose threats to people or property, such as weapon possession, firearm usage, launching explosives and missiles, or engaging in warfare. Most nations abide by an international agreement known as the Outer Space Treaty of 1967, which forbids nuclear weapons use, threats or tests of such weapons in space, and prohibits national claims of sovereignty on celestial bodies.
In addition to activities that are generally considered illegal, there are other activities that may be hindered or difficult to carry out in space. For instance, activities such as gambling, drinking alcohol, and smoking are highly discouraged or forbidden due to the potential risks associated with possessing and using the materials in an environment with no atmosphere or gravity.
It is also forbidden to travel in space without authorization from a government space agency, as the laws of many countries require citizens to obtain permission before launching commercial rockets or satellites.
Furthermore, certain activities may be taken for granted on Earth but are forbidden in space due to the extreme environment including walking/running, eating certain foods, drinking certain liquids, and even going to the bathroom.
Additionally, for the purposes of avoiding space debris, objects are not allowed to be released in space, thereby disallowing the disposal of waste.
Can you eat pizza in space?
Yes, you can eat pizza in space! Astronauts have enjoyed pizza during their time aboard the International Space Station for many years now. Pizza is actually a favorite of the astronauts because it’s a filling and delicious meal that is available in the prepackaged foods the astronauts are able to bring with them.
The astronauts just need to make sure to use a special biscuit cutter to cut the pizza into pieces small enough to be eaten in the zero gravity environment of the spacecraft. The crumbs don’t present a problem either since they can just be sucked up with a vacuum cleaner.
It may not be as enjoyable as pizza eaten on Earth, but it’s thought of as a treat among the astronauts!
Can astronauts drink alcohol in space?
No, astronauts are not allowed to consume alcohol in space. Although scientists have experimented on the effects of alcohol on zero gravity in the past, drinking alcohol on a mission is strictly prohibited by NASA due to safety reasons.
Alcohol consumption by astronauts can lead to dehydration, increased tolerance to the effects of alcohol, and a lack of coordination and inhibition due to the lowered gravity levels. Additionally, drinking alcohol can have a negative effect on astronaut health and performance, which can have serious implications during a mission.
Finally, due to the limited amount of space and the complexity of mission procedures, astronauts are often busy and unable to deal with the possible effects of drinking alcohol. For these reasons, alcohol consumption is not permitted in space missions.
Can food go rotten in space?
Yes, food can go rotten in space. Although for different reasons than on Earth. The main difference is the lack of microorganisms in space that are responsible for causing food to spoil on Earth. Microorganism growth relies on the presence of oxygen as well as humidity, both of which are largely absent in space.
In addition, rot cannot occur in the same way in space due to the vacuum. Without oxygen, the bacteria responsible for spoilage cannot function, and in space there is a lack of available water molecules, which is vital for the maturation of specific bacteria.
If the temperature and humidity levels are regulated, however, food can remain edible indefinitely in space.
In reality, space food rarely has the opportunity to spoil because it is consumed and finishes within a few days. In addition, food items taken into space must go through rigorous safety standards and must be pre-treated to reduce the risk of bacteria growth.
This is done through dehydration and vacuum packing, so food has a longer shelf life.
