Research has found that chemicals found in coffee including phenolic compounds and lignans may improve glucose metabolism, therefore reducing the risk of type 2 diabetes. Coffee is also rich in magnesium which has been linked with lowering type 2 diabetes risk. Previous studies found that just increasing your coffee intake by 1 cup per day decreased your risk by 11%.
But it is important to remember that the type of coffee matters. Lattes and other sugary coffee drinks were not studied. The type of coffee used in the experiments included an 8 oz cup of black coffee with minimal amounts of milk and sugar. So stick to the fresh brewed coffee with moderate amounts of sugar and milk in order to reap the benefits.
