I'll look into Las Lilas, thanks.
There should be more sources. I'm sure there are. I'd also buy it in bulk, luckily I've got a freezer. I'm limited in my research abilities as I don't speak Spanish. Hopefully, somebody here will have a clue!
Red meat is healthy if it's grass-fed and antibiotic/hormone free and cooked correctly. Morally I can accept it if the cattle has been raised and killed in the most human way possible.

All links link to further studies, and scientific papers, except the last one.
I took some bio-chem classes on the topics nutrition and digestion so I've got some background. PLEASE do not start a discussion about this topic here, open another thread. Thanks. I posted this to show why I'm so passionate about finding the right meat sources.
