Recent blood work would only give you the insulin answer if you specifically had a fasting insulin test done (not to be confused with fasting glucose, which is a measure of the blood sugar level).
I take the Zone fish oil, Sea Health Plus and Polyphenols XT (active ingredient in this is delphinidins from the maqui berry, which is a South American blueberry) The anti-inflammatory Zone diet together with the polyphenols and Omega RX produces positive results that you can actually feel and measure with blood testing. The omega 3's Dr. Sears recommends to reduce the cellular inflammation are specifically those found in fish (EPA and DHA), but you would have to eat enormous amounts of fish daily to benefit. The other downside is you'd be ingesting high amounts fo ocean pollution, if you could even manage to eat pounds of fish daily.
