A new review in The Lancet Planetary Health highlights how rising temperatures, extreme weather, and shrinking food quality are quietly reshaping the human gut microbiome. “Shifts in gut microbial composition might offer early warning signs of climate stress in human populations, helping guide targeted interventions. The clearest link between climate change and gut health comes through food. With Asia home to many of the world’s most climate-vulnerable populations, the gut microbiome offers a crucial—but overlooked—lens into how climate change is reshaping health from the inside out. —Source: Michigan State University ; Image: The Lancet Planetary Health/Asian Scientist MagazineThe study can be found at: Climate change effects on the human gut microbiome: complex mechanisms and global inequities
