And in other mind-blowing news – Dophins can induce and turn off diabetes
A friend just forwarded this article about dolphins’ newly-discovered ability to “turn on” type 2 diabetes when food is scarce (to keep blood sugar available to their large brains) and to turn it off when there’s plenty to eat.
While this doesn’t help solve the autoimmune piece of type 1, it does suggest that diabetes in humans may have developed as an adaptation to a protein rich diet and/or extreme cold during the last ice age, with higher blood sugar preventing frostbite (a northern-dwelling wood frog has just this survival mechanism). Part of the ice age theory (summarized in a NY Times article) is that cold temperature is a trigger for those genetically pre-disposed (northern European descent).
That would hold true with Lukas, who developed a mysterious fever right after Seattle’s 2008 heat wave sent us fleeing to Sequim to cool off. He never really recovered and was diagnosed a couple months later. Annecdotally, I’ve heard quite a few stories of diagnosis (type 1 and type 2) beginning with a sharp temperature change and fever.
Perhaps another evolutionary “just so” story, but intriguing (and a vote for living in warm, sunny climes)!
