By the time a child is 4-8 years old, his sugar consumption skyrockets to an average of 21 teaspoons a day. The same study found 14-18 year old children intake the most sugar on a daily basis, averaging about 34.3 teaspoons.
In space, the body begins to adapt to the microgravity environment. NSBRIâs science and technology program is addressing ways to reduce or eliminate many of the changes to the body that impact an astronautâs ability to perform well in space and that might impact their health after returning to Earth.
But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and that extends that period of time.

Sergei Krikalev, over six flights, has spent 803 days in space. Space is a harsh environment for humans.
