Twenty studies conducted around the world shows that coffee reduces the risk of developing type 2 diabetes by 50%. The researchers suspect the cause is chlorogenic acids in the coffee serve to slow absorption of sugar in digestion. Chlorogenic acid also stimulates the formation of GLP-1, a chemical that increases insulin (the hormone that regulates the absorption of sugar into the cells). Other substances in coffee that is trigonelin (pro-vitamin B3) is also thought to help slow the absorption of glucose.
