Space-driven ROS in cells: a hidden danger to astronaut health and food safety.

Astronaut nutrition faces supply, logistics, and cost challenges, making space farming a solution. While plants adapt to space microgravity may trigger oxidative stress. Research shows space-grown plants achieve Earth-like growth, but ROS accumulation remains a concern. This study examines ROS buildup in cells and its risks for astronauts, emphasizing effects on homeostasis, disease pathways, gut microbiome, and nutrition. This research provides new insights into oxidative stress in space missions.
