Did you jazz that astronauts recede weight in outer space ? Well they do , and we ’ve know about it forquite a while , but we did n’t really sleep with why . One possible reply , however , is a bit surprising .
mouth toPopular Science , Dr Scott Smith from NASA ’s Nutritional Biochemistry Laboratory said it might be because the spaceman are n’t run through enough . And why is that ? Because the nutrient is floating inside them , pull in them feel fuller than they really are .
“ I opine it ’s that food does n’t settle the same way it does on Earth , so that the stretch of your stomach – which beam the sign to your mentality to say ‘ you ’re full , terminate eating ’ – I think that gets triggered quicker in weightlessness than it does on Earth , ” he said .
Eating enough while in blank is important for a whole number of reasons . Not least because being weightless causes you to lose osseous tissue and muscle masses – which astronauts seek to compensate for by exercising regularly , about two hours a day on average .
They exercise using thing like a treadwheel on the ISS and a weighting motorcar . Each part of their twenty-four hours is allocate to include time to exercise . But rust is important too , especially things like fish , which let in omega-3 fat pane that can help bone wellness . And if you do n’t sense athirst , well , you might not be eating enough .
Floating food can cause other rather gross problems too . If you pass off to burp in space , well , it might find its way back up your sphincter .
“ When you eruct , you ’re belch through that sphincter at the top of your venter , ” food scientist Vickie Kloeris from the ISS food - systems lab toldThe Atlantic . “ eruct in microgravity is probably not something you want to do a wad of . ”
astronaut now supervise everything they ’re eating on an iPad app call EveryWear , allowing their squad back on Earth to tell them if they ’re eat enough . The astronauts read the barcode on their food with the pad of paper ’s camera , lease them quickly record what they are eating .
Meals on the ISS have come a retentive manner since the early days of outer space exploration , with astronaut consume everything from tacos topizza . Understanding on the button how our bodies process food for thought in space is important , though , as we eye up missions to more aloof locations like the Moon and Mars .
And , well , it depend like our stomachs themselves are n’t that well - suited to a weightless surround . If you ever find yourself in space , just remember , that meal is floating around in your belly – and you might be hungry than you believe .
