The best tuna for Omega-3? Here’s what you can expect in a six ounce serving.

• Yellow-fin or Ahi Tuna 400 grams

• Bluefin 2,200 grams

• Skipjack 460 grams

You’ll notice than canned Light Tuna is missing from this list. It is simply not a significant source of Omega-3, with just 340 milligrams from a six-ounce serving.

There are three types of Bluefin Tuna; Northern, Southern and Pacific.
Bluefin is dangerously over fished. The catch has declined by more than 90% over the past forty years.

If you are buying grass fed-beef in search of higher Omega-3 levels, keep in mind that all grass-fed beef is not created equal.

Yes… there are typically higher levels of Omega-3 fats in grass-fed beef. And there are environmental benefits as well.

In the fall of 2007, the U.S. Department of Agriculture unveiled standards to help consumers make sure they’re actually getting meat from animals fed nothing but grass.

But the standards are watered down and not terribly helpful. What the regulators allow beef producers to label as “grass-fed” can actually include beef that has been fed antiobiotics and hormones.

“The public perception is that grass-fed animals are on pasture, that they are not confined and are not given hormones or antibiotics.” says Dr. Patricia Whisnant, a veterinarian and president of the American Grassfed Association.
