Is the glucose monitoring craze really so healthy?

At £300 a go, the Zoe is a reassuringly expensive accessory. It has a recognisable logo and even had a 200,000-strong waiting list at one point. That wouldn’t be so unusual if Zoe was a must-have handbag or jewellery, but it is  a continuous glucose monitor that you stick to your arm.

Continuous glucose monitors have been available to diabetics for a few years, but now non-diabetics without any particular reason to worry about their pancreas are also getting in on the act. Like the fear of gluten a few years ago, glucose levels have gone from something only those with a diagnosed medical condition ever think about to a widespread obsession. There are many people who now worry that unless they eat a pear with peanut butter, or drink a cup of vinegar before their lunch, they might end up with elevated glucose levels which could have a range of damaging effects.
