No, glucose monitors aren't particularly helpful for people who don't have diabetes or pre-diabetes.
Pathologizing insulin spikes is yet another distraction from the reality of an untenable food environment.

My new piece is on the painfully slow process of scientific error-correction and how it harms real people all the time.
Also, why cinnamon probably isn't a useful treatment for diabetes.

The study itself has been cited, according to Google, 1,700 times.
