Insulin co-discovered by London's Frederick Banting 100 years ago today

Insulin was co-discovered as a powerful treatment for diabetes 100 years ago today by London resident and researcher Frederick Banting.
The treatment was discovered on Nov. 14, 1921 but the first dose of it was administered on Jan. 23, 1922 to a Toronto teen.
Prior to their findings, type-one diabetes — which is linked more to genetics than lifestyle decisions — would result in death. To this day, insulin is the most effective treatment for this kind of diabetes, saving the lives of millions of people.
Charles Best, from Pembroke, Maine, was also responsible for this breakthrough.
Dr. Stewart Harris, the Primary Care Diabetes Support Program's medical director at St. Joseph's Healthcare London, claimed that "insulin was conceived here in London, Ontario, and raised in Toronto" by Banting.
Banting won the Nobel Prize in Medicine in 1923 for this discovery. This was the first time that a Canadian was awarded the prize.
Insulin was distributed for public use that same year, and it's a discovery that Harris believes "all Canadians should be very proud and aware of."
"We'd have had a lot more deaths and we would not be recognized as a world leader," Harris told CBC News. "We still are today."
"I think it really leapfrogged Canada to the front of medical science and discovery," he said. "I look at insulin discovery as a foundational discovery for Canadian research and Canada on the world stage as a major leader in scientific discovery and especially diabetes."
Despite this miraculous innovation 100 years ago, Harris still described diabetes, particularly type-two which is associated with obesity, as an "epidemic."
According to the World Health Organization, there are approximately 422 million people with diabetes globally, and about 1.5 million deaths as a result of it.
"One of the biggest challenges is to ensure that we have access for all to these life-saving therapies," Harris said. "And that is one of the globally — and here in Canada — one of the biggest challenges we have. Insulin is not cheap to make."
He said that this could affect people like new immigrants and the "working poor person" under the age of 65.
"Even in my own clinic we run into this, to try and help people who don't have insurance coverage — whether it's government or through their jobs, to be able to afford insulin therapy. That's still a major barrier."
