I've been supplementing my canned sardine intake with some canned tuna - primarily for variety, but also on a lark to see if it also doesn't taste as bad as I had feared. Good news on that front, it's actually quite palatable!
However I'm confused - I've run across a number of cans that report having no fat per serving (all wild-caught, dolphin safe, BPA-free cans). 0 total fat, 0 saturated fat, 0 trans fat. How is this possible? Part of the reason I'm eating fish to begin with is to get a "more natural" source of fish oil (yes, not totally natural, but as convenient and portable as possible) - but if there's no fish oil in these cans, I almost feel like I'm wasting my time.
So are they doing something to this fish to somehow remove all the fat before/during the canning process?
Or does this fall under the "Well it's less than 1-2g so we can report it as 0g" kind of marketing malarkey?
