Hi Al,

I'm aware of the USDA data, but it doesn't really answer the

question of whether oil helps to release and/or retain calcium in

sardines better than spring water. The only two entries they have in

USDA are for different types of fish (Atlantic and Pacific) so no

meaningful comparison can be made.

However, I do appreciate you taking the time to look them up and

assist me. Thanks very much.

Katrina.

Katrina: I suggest you ask the manufacturer. Most of them have websites

now and welcome feedback and questions from the public. I've done this many

times with success - both e-mailing them or calling their customer service

line. Do a google search and see if you can find them. (Could just be a

labeling error - but if it concerns you, try to ask them).

Actually, I figured it out myself. I checked out many tins of

sardines for their calcium content and the ones that had the highest

levels were always in soybean oil. Substitution with any other kind

of oil/juice/water always lead to a decrease in calcium content. So

I've identified the pattern, and my guess is that the particular

soybean oil used also contains calcium. I like a good puzzle :-)
