Bump for answer! I've been cooking my liver, but I wonder if I've been depriving myself of anything. Does cooked liver provide the same anti-exhaustion properties as raw? I know my reps are up since eating more liver, but is it worth eating raw to further enhance my endurance? Granted, I'm getting liver from pastured, grass-fed cows, so I'm not terribly worried about disease. Plus, if you freeze it for a few weeks, doesn't that kill most parasites? And then you can thaw and eat it raw more safely?
