Following this question and other food-related questions, including on Quora, I failed to see mention of a meal without meat or fish. I suppose:



  • It is technically possible to have healthy vegetarian space food?

  • As any other human being, astronauts may have alimentary restrictions (whatever the reason).

Has there already been an astronaut who ate vegetarian for all their journey in space? Let's restrict this question to journeys longer than one day (otherwise, not eating would be valid).

          Yes, a simple Google query returns a few astronauts who were or are vegetarians:




          • Kalpana Chawla was a
            strict vegetarian and spent a total of 31 days in space.


          • TJ Creamer - 163
            days


          • Dr Janice Voss - 49 days.

          From the answer to my previous question that you linked:




          In the shuttle and post-shuttle era, with actual toilets available, astronauts have more options, and can pretty much ask for whatever they want for their pre-flight breakfast -- for example, lobster and baked potato -- but many stick to the steak-and-eggs tradition.




          In this modern age of manned space flight, having convenient and working toilets means that crew members can enjoy any dietary requirements they might have, limited only by the olfactory tolerances of the companion crew members and NASA guidelines.



          Foodstuff that might cause health issues (oysters, shellfish, etc.) or otherwise might affect the other crew members or equipment/mission might well be denied. However, that's a different question.

            @called2voyage: “extra items (products such as humus, tofu, quorn and fortified cereals, and fortified soy drinks) that are typically used by vegans and vegetarians were included” (emphasis mine). Of course you can make any diet work if you add supplements. I do think that a vegan diet is best from an ethical and environmental standpoint, but it’s hard to get enough protein and some micronutrients from plants only.

            "it’s hard to get enough protein ... from plants only." Not exactly. The larger problem is getting the right combination of amino acids for assimilation into human proteins. Amino acids are the thing, because all ingested proteins are broken down to their amino acid components by digestion before being reassembled into our proteins.

            @OscarLanzi: True, but the amount itself is also a problem. To reach 1.5g protein per kg body mass I’d have to eat half a kg of dried chickpeas or other legumes which would have ~1500kcal on their own. With food such as low fat curd cheese or eggs it’s much easier and they have a better amino acid profile. Sorry for starting this discussion.

          As astronaut is always to choose the food of his/her own choice . They have a tasting period of 15 days to eat and choose what foods he/she likes to eat in space and the food choice has to meet the standard for rocket travel though. Of course there will be moderation by nutrition experts to ensure the astronaut is getting the recommended diet value of car/calories and so on.



          Kalpana Chawla, a vegetarian stayed in space for close to 31 days. There are a few other people who stayed much longer than this.



          P.S.: Not every astronaut is going to be vegetarian but if they are going to Mars they should become vegans. The Mars living room test (underground test) for 1 year included only vegan foods.

            Welcome to Space! Can you support your answer with references? For example, where did you get the information that Kalpana Chawla was vegetarian? Do astronauts have as much choice over their diet as you claim? Why "should" astronauts going to Mars be vegetarians? You need to support these claims in your answer.

            It's incorrect to say that "As astronaut is always to choose the food of his/her own choice". There are strict limitations on what can be flown in spacecraft. They are allowed to pick their food choices from the list of allowable foods.

            @OscarLanzi: True, but the amount itself is also a problem. To reach 1.5g protein per kg body mass I’d have to eat half a kg of dried chickpeas or other legumes which would have ~1500kcal on their own. With food such as low fat curd cheese or eggs it’s much easier and they have a better amino acid profile. Sorry for starting this discussion.

          In addition to the vegetarian and even vegan astronauts mentioned elsewhere, there soon may be more. In at least one of many possible scenarios for food on long flights, NASA astronauts on the proposed Mars mission for 2030 will be on vegan diets. The need for sustainable food options and preservability of the food is driving this choice.

            "Healthy" is unsourced and doubtful - it's a challenge to supply all the nutrients through a vegan diet, and as humans are hypocarnivores, a healthy mixed diet is much easier than a healthy vegan one. The near-impossibility of an ecosystem more complex than a simple bacterial-plant cycle in confined space quarters is what's driving this choice.

            @called2voyage: “extra items (products such as humus, tofu, quorn and fortified cereals, and fortified soy drinks) that are typically used by vegans and vegetarians were included” (emphasis mine). Of course you can make any diet work if you add supplements. I do think that a vegan diet is best from an ethical and environmental standpoint, but it’s hard to get enough protein and some micronutrients from plants only.

            "it’s hard to get enough protein ... from plants only." Not exactly. The larger problem is getting the right combination of amino acids for assimilation into human proteins. Amino acids are the thing, because all ingested proteins are broken down to their amino acid components by digestion before being reassembled into our proteins.

          As astronaut is always to choose the food of his/her own choice . They have a tasting period of 15 days to eat and choose what foods he/she likes to eat in space and the food choice has to meet the standard for rocket travel though. Of course there will be moderation by nutrition experts to ensure the astronaut is getting the recommended diet value of car/calories and so on.



          Kalpana Chawla, a vegetarian stayed in space for close to 31 days. There are a few other people who stayed much longer than this.



          P.S.: Not every astronaut is going to be vegetarian but if they are going to Mars they should become vegans. The Mars living room test (underground test) for 1 year included only vegan foods.

            Welcome to Space! Can you support your answer with references? For example, where did you get the information that Kalpana Chawla was vegetarian? Do astronauts have as much choice over their diet as you claim? Why "should" astronauts going to Mars be vegetarians? You need to support these claims in your answer.

            It's incorrect to say that "As astronaut is always to choose the food of his/her own choice". There are strict limitations on what can be flown in spacecraft. They are allowed to pick their food choices from the list of allowable foods.
