While continuous glucose monitors (CGMs) may be of significant help to people living with diabetes, they may harm healthy adults by showing inaccurate results that can lead to unnecessary food restrictions, according to a study on Wednesday.

CGMs were originally designed to help diabetics manage their blood sugar. It helps by tracking glycaemic index (GI) -- a measure of how quickly a food can make your blood sugar. However, these devices are now increasingly being used by health-conscious adults to track how different foods affect their glucose levels.
