Inflammation has gone from a condition you should worry about to a marketing buzzword used to sell everything from drugs to juice to cereal.
Well, at least they got it half right: You should worry about inflammation, and do what you can to bring your own levels down.
But forget the drugs, juice and cereal - because none of those things will ever beat the anti-inflammatory powers of plain old fish oil, and the latest research proves it again.
A new look at data on 702 patients who took part in one of 11 clinical trials finds that people who take fish oil supplements have lower blood levels of homocysteine, an inflammation marker linked to everything from heart risk to dementia to bone breaks, according to the study in Nutrition.
Other studies have also found that fish oil can put the hurtin' on homocysteine.
One published in 2009 found that omega-3 supplements reduced levels of the inflammation marker by 22 percent in diabetics - versus just one percent among those who took a placebo.
And that's really only the beginning of the benefits.
Studies have found that healthy omega-3 fatty acids can help protect your heart, eyes, and gums while raising levels of HDL ("good") cholesterol and lowering levels of deadly triglycerides.
Fish oil can also help boost the mood and beat depression - especially among seniors. (Read more here.)
The best sources of these omega-3s are fatty fish such as salmon, tuna, trout and herring - and the highest concentrations are often in the one part of the fish you're probably not eating: the liver.
Researchers looked at a dozen fish commonly eaten in Spain and found all had livers rich in the long-chain polyunsaturated fatty acids you need for good health.
And if you like anchovies, good news: The livers of these famously oily little fish had some of the highest omega-3 levels of all.
But why stick to the liver when you can eat anchovies whole?
OK, I know that's not for everyone - but if you don't like anchovies, fish livers or even fish itself, there's a simple solution: a high-quality fish oil supplement from a company you trust.
Some can leave a fishy aftertaste or, even worse, a case of the "fish burps," but don't give up - refrigerate your capsules instead.
And if that doesn't work, try a different brand until you find one that leaves you with all the benefits... but none of the burps.
