TL;DR
Special types of water called "reduced water" can protect against cell damage that leads to type 1 diabetes by blocking harmful oxygen molecules.
Key Finding
Reduced water completely prevented reactive oxygen species generation from alloxan and increased glucose-stimulated insulin secretion by 2-4 fold in pancreatic beta cells grown in the laboratory.
Summary
This laboratory study tested whether reduced water (water treated to contain extra hydrogen) could protect pancreatic beta cells (the cells that make insulin) from damage caused by alloxan, a chemical that triggers type 1 diabetes in animals. Researchers found that reduced water prevented the harmful effects of alloxan by neutralizing reactive oxygen species (unstable molecules that damage cells), and it increased insulin production by 2-4 times compared to untreated cells.
Practical Takeaway
While this cell culture study suggests reduced water may protect insulin-producing cells from oxidative damage, it is very early-stage research conducted only in cells, not in animals or humans. Much more research would be needed to determine whether drinking hydrogen-rich water could actually help prevent or treat type 1 diabetes in people.
Abstract (excerpt)
Reactive oxygen species (ROS) cause irreversible damage to biological macromolecules, resulting in many diseases. Reduced water (RW) such as hydrogen-rich electrolyzed reduced water and natural reduced waters like Hita Tenryosui water in Japan and Nordenau water in Germany that are known to improve…
