Deep dives
The Rise of Glucose Monitoring
There is a growing fascination with blood glucose tracking, largely fueled by influencers and wellness companies promoting personalized nutrition based on glucose levels. Devices like continuous glucose monitors (CGMs) claim to provide insights into individual responses to food, potentially helping people manage their weight and health more effectively. Specific dietary recommendations, such as the order in which foods are consumed, could lead to significant reductions in glucose spikes. However, experts caution that while there is promise in personalized nutrition, the science is still emerging, and the accuracy and usefulness of such data in healthy individuals remain questionable.
