A few extra trips to the water cooler could help prevent type 2 diabetes, says a preliminary French study. People who drank the most water (up to 1 L a day) had a 30-percent-lower risk of developing diabetes than their counterparts. Scientists found that when your body is dehydrated, a water-regulation hormone called vasopressin is released, which over time can lead to strained insulin response and production.
Drink 1 to 2 L of water a day to help combat diabetes (and feel fuller to boot!).
