I've been using Cronometer for many years and love it! As a dietitian working with people in different age groups it would be great to be able to use UK DRVs rather than the US ones. Yes there are some similarities with some nutrients but I don't feel i'ts best practice for me to be using recommendations for a different population. I could customise but it's difficult doing this for each age group (I would have to do this 9 times for children!).
