I didn't know about it until I put on CGM and noticed the spikes. Then used google to figure it out. Which is also why I think it is useful to try putting CGM for couple of weeks just as a learning experience. Most people will never have CGM on and hence no way to really understand how different food they eat influences their blood glucose.
