Scientists discover why high altitude protects against diabetes

SMRTR summary

Scientists have solved the mystery of why people living at high altitudes develop diabetes less frequently than those at sea level. Researchers discovered that in low-oxygen environments, red blood cells act like "sugar sponges," absorbing large amounts of glucose from the bloodstream to help deliver oxygen more efficiently to tissues, thereby lowering blood sugar levels and reducing diabetes risk.
