If you've been reading my eTips for a while now, you know how important omega-3 fatty acids are.

Specifically, the omega-3s DHA and EPA are some of the most powerful anti-inflammatories that you can find in nature.

They can boost your heart health... improve diseases from diabetes to Parkinson's... and even guard your brain from Alzheimer's.

Now, you might think that the best -- or even the only -- way to get your DHA and EPA is by taking fish oil supplements.

But according to a new study, there's another kind of oil you should know about if you want to protect your brain.

And it's from a shellfish called krill!

Now, if you're not familiar with krill, they're shrimp-like crustaceans that tend to favor the cold waters off Antarctica. And though they're TINY in size, their oil is MIGHTY when it comes to your brain health.

In a study out of China, researchers induced Alzheimer's in mice and then supplemented their diets with krill oil.

By the end of the study, the mice performed better on learning and memory tests than they had before receiving the krill oil.

That means that the oil actually REVERSED some of their cognitive deficits!

When the researchers studied the mice's brains closely to determine why that might be, they found that the krill oil had reduced the accumulation of something called "amyloid" in the mice's hippocampi, the parts of our brains that play a

key role in both short- and long-term memory.

And since previous research has shown that amyloid "plaques" and "tangles" are a signature sign of Alzheimer's damage, anything that can chip away at them is a major boon!

Now, I recently shared with you that INFLAMMATION is what gets the ball rolling on amyloid deposits in your gray matter.

And we know that the DHA and EPA in krill oil can help snuff out those flames. In fact, there's some evidence that krill oil may be MORE effective at raising your levels of DHA and EPA than even fish oil!

That's because most of the omega-3s in krill oil are found in molecules called phospholipids, which may be easier for your body to absorb than triglycerides, where most of fish oil's omega-3s are stored.

So, if want to hold onto your precious memories, why not give krill oil a try?

Of course, you won't find any krill at your local seafood buffet. The biggest consumers of it are whales -- not people!

But krill oil supplements are readily available at health-food stores and online. Look for a brand that sources its krill straight from Antarctica.

I should note that krill oil also contains astaxanthin, the same powerful antioxidant that gives salmon and shrimp their pink color and has been proven to ease inflammation and oxidative stress.

And if you need yet another reason to ramp up your intake of astaxanthin, I've got some good news for you in tomorrow's eTips.
