SaralnamaAstronaut Shubhanshu Shukla posted a video on about eating in space. He said it's challenging and you can 'eat water'. Dr Anjana Kalia explained that astronauts face unique digestive issues in microgravity. Without gravity, gas mixes with food, causing 'wet burps'. Peristalsis, not gravity, moves food through the digestive system. Digestive enzymes and bile help break down food. The small intestine absorbs nutrients using villi and microvilli. These processes work in space if astronauts eat a balanced diet. Shukla's video shows how habits matter when eating in space to avoid making a mess. (Updated 12 Sep 2025, 18:02 IST; source: link)
