Vegetarian astronauts

Apparently, zero gravity causes fluid to accumulate in the head. Among other things, this clogs the sinuses, impairing the sense of smell. NASA says "since crewmembers' sinuses fill with fluid as the body fluids reach equistatic pressure, the senses of taste and smell are reduced. Hence, astronauts on-orbit always prefer food to be more highly seasoned in order to taste acceptable."

Some high school students invented something called Stellar Strips for an innovation competition. They are like those breath freshener strips that melt in your mouth, except these are flavored with condiments. The idea is to put the strip in your mouth with the food--after all you can't really wield a salt shaker in outer space. For Better Taste in Space: Student Research Backed by NASA

Nutrax is right.

Also cf. Star Trek - the first series.

One of the reasons airline food is so meh is that at 35,000 feet, taste and smell are affected. So, it's no surprise that space travel would have similar problems.

I was told that alcohol has at least twice the effect at 35000 ft - but it never felt like it, despite my repeated attempts to prove this theory (fact?)

Those condiment strips sound really cool. I wonder if I can get some to take to my in-law's house when I have to eat dinner there. :)

I hope if this goes through they have someone on board who is good at raising plants along with the one who will cook. It's not usually something that anyone can do on a wing and a prayer, and I would think that the strange growing environment of nutritional water instead of soil might make it more challenging.
