EPA is a form of omega 3. It's found in animal products, and it's the form I'd like to have for it's anti-inflammatory properties.
The form of omega 3 found in plants is
ALA. The body can convert some ALA to EPA, but it's very inefficient - maybe 5% gets converted. That's why vegetarians are at a disadvantage here.
Then I read a study (or at least the abstract
) in which 10 post-menopausal women saw their plasma EPA rise 30% over baseline in 7 weeks. (Of course, if they were eating a SAD, baseline may have been pathetically low.
) I just thought it was an amazing increase in EPA from a plant source of omega 3.

I'm a big believer in grass fed beef. I do wish it were not so expensive. I got spoiled when I lived in TX and could get grass fed at a very reasonable price. Still, it's a priority for us.

I'm becoming more and more a big believer. I live in Kansas, and there are a few farmers in the area who raise grassfed beef. Unfortunately low-fat is still a selling point. Since I'm eating this meat for the higher omega 3 and for the CLA, I don't want low-fat.
My top choice for beef is a local farm whose fattiest ground beef is available for $5.88/pound. Unfortunately they aren't a steady supply. The store where I buy it may be out for long periods of time. (I really need to invest in a freezer, so I can stock up.) I also buy their liver and stew meat when it's available.
My alternate source is from a bigger operation out of Colorado, I think. It's lean:fat ratio is 85/15 or 80/20 (I can't remember) and costs $8/pound. As you say, very expensive.
If I can't find what I want in grassfed beef, I go for bison which is usually grassfed. I did accidently buy some grainfed bison recently. I didn't know there was such a thing, so I didn't read the label until I got home.
