    Just lately I really fancy shellfish - shrimps (not available around here unfortunately), mussels, scallops etc. What exactly is the difference in nutrients between 'normal' fish and shellfish? Why don't I fancy, say, flatfish or oily types?
    Thank you!

    Why don't you fancy flatfish or oily type? Yeah right why don't you?!
    Maybe just have what you fancy verses what you should fancy?
    I am pretty sure shrimps scallops, mussles have nutrition for the heart...

    I went and bought a dab, a by-catch flatfish, as they did not have shellfish. It was very nice, but I still dream of the lovely shrimp we bought up in the Lake District a few days ago .....
    I was just curious why I suddenly fancied mussels and the like. They must have different nutrients from the shell-less fish.

    I guess your body knows something you don't know. It is usually the case , isn't it!

    You're right but I'm curious - and I can't get shrimps here in Somerset so if I knew what it is that attracts me in them, I can get something else with the same nutrients.

    Yes I always do that first, though I prefer DuckDuckGo (the search engine which does not track you). However I got nowhere on either that or Google. So I thought I'd pick your brains .....

    Duck duck go is where I go to find my answers too. When I first started with them, they didn't seem to track my activities, but I am suspicious that of late, even they are.
    A few adverts of things I have looked up have come through on browsing... I wonder if What you think

    Sorry from dragging you away from shrimps

    I haven't checked that - I try google sometimes after using duckduck so it would be complicated. I tend to trust they do what they say. There are maybe other ways how the computer can find out what you are interested in?

    There's a lot wrong with MFP - their unfailing belief that calories in = calories out, for example, or that fat is unhealthy. But if you can ignore those there's information in there.

    Thank you Crowan, I shall study this site. The website I always use for finding out about nutrients is http://nutritiondata.self.com but had not thought of doing that. I'd hoped to find some general simple info, rather than having to look up various single fish on there ... the nutritiondata has rather a lot of different ones!

    I don't know other search engines well, but Google seems to be getting harder and harder to use. I ask a question and it answers what it 'thinks' I should be asking. I asked, 'What are the fattiest cuts of meat?' I got a lot of sites listing the leanest cuts. I tracked down the information eventually, but it took some doing.

    A very quick comparison between shrimp and crab on the one hand, and fish (pollock, mackerel, cod, flatfish and salmon) showed the following.
    Shrimp has (much) more selenium, B12, iron, copper and zinc. Crab has lots of B12, selenium, copper and zinc. Most of the fish seems to have no advantages in anything, though mackerel and flatfish have lots of selenium too. The fish had slightly more protein.
    So the crustaceans win on minerals in general, and the vital vitamin B12.
    Though this was just a very quick look, mainly on http://nutritiondata.self.com.
