I've recently had lots of very helpful advice regarding a question I had about iron levels (BIG thanks to everyone who replied!), and, as a result, I'm logging my daily iron intake to try to get a clear picture of how much I take in through diet, without supplementing.
I came across this reference website, which I consider to be an excellent resource for information about about the components of many food stuffs. In the UK we do not have iron information on food labels, so I've found the information available here very useful and I thought I'd highlight it, in case it might help anyone else with the same level of inquisitiveness as me!
