BBC World Service - The Food Chain, What do astronauts eat?

Designing a diet to keep astronauts healthy

What are the nutritional challenges, and the highs and lows of food in space? As NASA looks at creating a lunar habitat, and even launching a mission to Mars, how can the right food be prepared and transported to keep astronauts both healthy, and happy?  Marie Keyworth speaks to veteran astronaut Nicole Stott, and NASA’s top nutrition expert Scott Smith, who leads the Nutritional Biochemistry Laboratory at NASA’s Johnson Space Center, in Houston, Texas. Marie finds out what it’s really like to eat in zero gravity, and how nutrition is being used to counteract the extreme health impacts of spaceflight on the human body. Studying astronaut diets in space might even help our understanding of nutrition here on earth.  

Presented by Marie Keyworth. 
Produced by Sarah Treanor.
