Yes, I know that we should have grass-fed, not grain-fed, beef.
But lets assume that we can't reasonable get any access to grass-fed beef. For example, here (in Argentina), 80% of the beef is grain-fed AND there is no labeling nor differentiation between grain-fed and grass-fed. So you never know if you're eating grain or grass-fed beef, but it's probably grain-fed. We use some shorthands and proxies to try to guess (how yellow is the fat; how expensive is it; etc) but they are not especially accurate and fundamentally, in Argentina, you really never know if it's grass or grain fed. So I would guess that the vast majority of meat I eat is, unfortunately, grain-fed, no matter how much I try.
So I'm wondering: how bad is this?
In other words, lets assume that all the beef available is grain-fed. With that assumption: is it worse to eat a lot of grain-fed beef -- or no beef at all? Should I then only eat limited quantities of (this grain-fed) beef and just have lots of other paleo-ish foods instead? Or...?
How do I survive as paleo in a world of only grain-fed beef! Please help! :)
CLARIFICATION: since many of you expressed surprise at my stats above, I want to clarify: I know the grass-fed rancher community here quite well, and this issue is publicized here all the time. Basically, 15 years ago, it was 90+% grass-fed; today it is about 20% grass-fed. The information in wikipedia is just outdated (I remember about 6 years ago, everyone was talking about how it is 50% grass-fed) -- over the last decade, Argentina has adopted many of the modern American methods, unfortunately. Note that the 20% who are resistant to it are quite strong and building up a "traditional argentine" beef culture, the good restaurants only serve grass-fed, and I'm helping start-up an initiative to label the grass-fed beef, etc...
