Astronauts face a long list of health risks on long-duration spaceflights.

NASA is working to understand what role nutrition can play in helping astronauts stay healthy.

Nutrition can help astronauts manage spaceflight risks in the ISS but Mars missions can take years .

The authors present evidence that supplements can't be replicated by whole foods.

No food system exists to meet the nutrition, acceptability, safety, and resource challenges of long-duration spaceflight, researchers say.

Without a food system, astronauts will suffer and possibly face catastrophic failure, they say.

A space food system should be available on every human mission, the authors write.
