‘Keep Me going...’™ has a Glycaemic Index (Gi) of 50. This has been calculated as eaten (but without adding milk; a with-milk value is likely to be significantly lower).
Gi was independently calculated by Hammersmith Hospital, London, over a two week period and using a team of volunteers.
A quick visit to one of the main grocery retailer websites - or a simple internet search - will reveal loads of information about what this means, including the Gi values of many common foods. (We’d love to say more, but recent EU rules restrict the amount of information we can provide on-pack).
