This international holiday has been celebrated since 1991. however, the 14th day of November was not chosen at random, as it commemorates the anniversary of the birth of the great Canadian scientist who discovered insulin in the 1920s - Frederick Grant Banting. World Diabetes Day was established by the International Diabetes Federation to raise awareness of the disease, which appears to be an epidemic of our times. The event promotes numerous forms of support for people affected by diabetes, ways of preventing the disease or reducing the negative effects in people who already suffer from this metabolic disorder.
