Making A Meal Fit For An Astronaut
Life on the International Space Station throws some wrenches into how food and eating work. There’s very little gravity, after all. And there are big differences between nutritional needs on Earth and in space.
Astronauts must exercise two hours each day on the International Space Station to prevent bone and muscle loss, meaning daily caloric intake needs to be somewhere between 2,500 and 3,500 calories. Sodium must also be reduced, as an astronaut’s body sheds less of it in space. Astronauts also have an increased need for Vitamin D, as their skin isn’t able to create it from sunlight as people on Earth do.
So, how do all these limitations affect the food astronauts eat? Joining guest host Kathleen Davis to answer these gustatory questions is Xulei Wu, food systems manager for the International Space Station in Houston, Texas.
