This seems to be related to the use of CGM by people without diabetes (eg the Zoe thing) where people without diabetes can become unduly concerned by perfectly normal glucose variation, and might drop some foods out of their menu because of a wobble they saw on a Libre.
These quotes seemed to outline the conclusion of the study?
Professor Javier Gonzalez from the Department for Health said, "CGMs are fantastic tools for people with diabetes because even if a measurement isn't perfectly accurate, it's still better than not having a measurement at all. However, for someone with good glucose control, they can be misleading based on their current performance.
"For healthy individuals, relying on CGMs could lead to unnecessary food restrictions or poor dietary choices. If you want to assess your blood sugar accurately, traditional methods are still the way to go. We want to better identify the sources of the error in CGMs so that we can improve their performance in the future and have active research on this topic."
According to Professor Javier Gonzalez from the University of Bath, the inaccuracy of CGMs can be attributed to several factors:
"CGMs may be inaccurate because they measure glucose in the fluid surrounding your cells, not directly in your blood. This can lead to discrepancies due to factors like time delays, blood flow, and how glucose moves between different parts of the body."
Helen Whitby, Company Nutritionist at Innocent Drinks, said, "Smoothies and whole fruits are packed full of natural goodness and provide steady energy without sharp blood sugar spikes. We're on a mission to make it easier to live well through the delicious goodness of fruit and veg and this research confirms that blending fruit doesn't affect its health benefits, contrary to some myths."
Interesting that Innocent Smoothies are referenced.I wonder if they may have been involved in the funding of the study.
