Summary

Scott M. Smith leads the Nutritional Biochemistry Laboratory at NASA Johnson Space Center. This group is charged with keeping crews healthy with respect to nutrition, including using nutrition to optimize astronaut health and safety. This work includes ground-based and spaceflight research to understand how nutrition can mitigate the risks of spaceflight.

Smith has ongoing research projects on the International Space Station. Smith has also led several ground-based research projects to better understand astronaut health in space, including studies of vitamin D in crews in Antarctica, studies of crews living on the bottom of the ocean, and studies of test subjects spending weeks to months in bed.

In this episode we discuss:

What can we apply from astronauts’ unique nutritional needs down here on earth?
How to combat extreme oxidative stress
Which biomarkers are the most important to monitor.
What space flight can teach us about bone & muscle health.

0:00.0	Welcome to the Dr. Gabriel Lyon Show, where I believe a healthy world is based on transparent
0:08.5	conversations.
0:14.4	I'm very excited to bring you this special episode of the Dr. Gabriel Lion Show, in which I
0:19.6	sit down with Dr. Scott Smith, who leads
0:22.8	the nutritional biochemistry lab at NASA Johnson Space Center. This group is charged with keeping
0:29.1	crews healthy with respect to nutrition, including nutrition to optimize astronaut health
0:34.3	and safety. This work includes ground-based and space flight research to
0:40.5	understand how nutrition can mitigate the risks of spaceflight. Smith has ongoing research
0:47.5	projects on the International Space Station, his past projects have been flown on the space station,
0:53.4	space shuttle, and the Russian space station.
0:58.5	Smith has also led several ground-based research projects to the bottom of the ocean, not to mention
1:06.6	studies of vitamin D in Cruz in Antarctica.
1:11.7	Smith is a member of the American Society for Nutrition, the American Physiological Society,
1:16.7	and a whole bunch more.
1:18.4	He is one amazing individual.
1:21.0	I found this episode really, really interesting.
1:23.6	We talked all about the biomarkers measured in an astronaut.
1:27.4	What are the biomarkers that we see that
1:29.3	vary from space to earth? Oxidative stress that the astronaut will face. What are the nutritional
1:37.6	strategies that one can use to mitigate this? What are the implications of vitamins and minerals, particularly vitamin D, as it
1:47.1	leads to immune function, both in space and on Earth? We talk all about the nutritional needs
1:55.3	of the astronaut, as well as the nutritional needs of the earthbound human.
