Non-diabetics are using diabetes technology to track their blood sugar and improve their health - MarketWatchShe has found out all kinds of things, including that a banana, for example, is “one of the things that will spike my glucose the highest” — more than a cookie, she says. “It’s raised more questions than answers, honestly.” As glucose monitoring technology has improved in recent years, with new continuous glucose monitors (CGMs) making it easier and less invasive to track glucose levels comprehensively over the course of days or weeks, non-diabetics have also seen an opening. Because the devices require prescriptions in the U.S. and insurance coverage varies, it can be a troublesome and expensive endeavor. But Grant and others believe the effort is worth it. Glucose tracking can help people understand their health, they say, gaining insight into things like diet, exercise and energy levels. And research has begun to suggest that the information could also help people who are at risk of diabetes or heart disease.
