This is an odd question - I was wondering if the speed of action of the enzymes in the mouth breaking down food was related to a person's general metabolism.
My OH and I carried out an experiment by each of us melting a polo mint in our mouth (we weren't allowed to speed up the process by sucking the mint). My polo mint was only half dissolved when my OH's had completely dissolved.
My RMR has been tested and is 1166 Kcals/day so is <very> slow. I have a perfect TSH (slap bang in the middle of the reading) so I apparently don't have any problems with my thyroid.
The experiment with the mint seemed to confirm the slow metabolism.
Or is this complete nonsense and whimsy on my part?!
