    Thanks to Juhana, I've now been able to compare four sources:
    1. United States Department of Agriculture Food Composition Database
    release 17;
    2. a Special Interest Group on vitamin D that reported to the USDA in
    3. National Public Health Institute Nutrition Unit Fineli Food
    Composition Database release 4 (Finland); and
    4. Danish Institute for Food and Veterinary Research Food Composition

    The USDA obviously feels it has problems with vitamin D, and has
    deleted many of the vitamin D values of the SIG. It's true that
    factors of 3 differences between the various sources are common.
    However, it means that FINELI and DIFVR are each much more complete
    sources for D than the USDA is. So, I'll be sorting out the best
    agreed values for the foods I eat over the next while and use them
    until something better appears.

    Then it'll be on to iodine ...
