00:00A hidden gut reaction may explain why vegetables are so healthy.
00:03Researchers at Karolinska Institutet made the discovery.
00:07Gut bacteria can combine nitrate and iron from food.
00:10Together, they create molecules called deionikes.
00:14These molecules can travel throughout the body.
00:16They were found in the liver and kidneys.
00:18Beets and leafy greens are rich in dietary nitrate.
00:21The molecules were absent in germ-free mice.
00:24That suggests gut bacteria are essential to their formation.
00:27In animal studies, higher DNIC levels improved health markers.
00:32Researchers saw lower blood pressure and better vascular function.
00:36Blood sugar control also improved.
00:38And less fat accumulated in the liver.
00:40The findings show how diet and gut microbes may work together.
00:44But human studies are still needed.
00:46Scientists now want to track these molecules in people.
00:49This could reveal a new way vegetables support long-term health.
