Which one is healthier: fresh cod or salted cod?

As well as fresh cod, you can also buy dried and salted cod, which is a great way to preserve it with hardly any loss of nutrients. Both versions of this highly versatile fish are equally healthy, provided you desalt and rehydrate it properly. Otherwise, you run the risk of exceeding the World Health Organisation’s recommended sodium limits, something you should be especially aware of if you have high blood pressure or fluid retention problems.
