Water is indispensible to life and health, and scientists are finding more aspects of life and health that are water dependent. Today’s excerpt provides yet another reason to remain hydrated.

When the body is dehydrated, vasopressin levels rise, prompting the kidneys to hold onto water. At the same time, the hormone pushes the liver to produce blood sugar, which over time may strain the ability to produce or respond to insulin.

One of the largest studies to look at the consequences was published last year in Diabetes Care, a publication of the American Diabetes Association. French scientists tracked more than 3,000 healthy men and women ages 30 to 65 for nearly a decade. All had normal blood sugar levels at the start of the research.

After nine years, about 800 had developed Type 2 diabetes or high blood sugar. But those who consumed the most water, 17 to 34 ounces a day, had a risk roughly 30 percent lower than that of those who drank the least. The researchers controlled for the subjects’ intake of other liquids that could have affected the results, mainly sugary and alcoholic drinks, as well as exercise, weight and other factors affecting health. The researchers did not look at eating habits, something future studies may take into account.
