I don't look forward to making juice, it takes a little while and doesn't taste good enough to justify the time it takes to make it. It requires a big heavy machine to sit on my counter top, and worst of all perhaps the ingredients (fresh fruits and vegetables) are the most expensive part of my diet. Celery, cucumbers, carrots, cilantro etc. are very expensive, and hard to find local sources.
Yes, green juice is impossible without technology. Why not eat the greens instead? All that veggie sludge ... my chickens would like it ... but juicing wastes much of the produce, doesn't it? And produce
IS really expensive now. And you are right that liver is a way better choice for vitamins and minerals, and at $1.89 for grassfed beef liver, sliced and all, it is a much better bargain.
Liver is high in copper though, isn't it? Our well water has a lot of copper naturally, so I try to limit liver to once a week. We filter our water, but I have never tested it for copper after filtering. It's not harmful levels, just at the high end. But I am digressing off on a tangent.
I would try the middle road of some juice, some organs. I am saving so much money eating less plant matter than I used to. Animal foods have more protein, fat, calories, vitamins and minerals than most, if not all plants. It is a slow process for me to switch over, as I love fruits and veggies. But I have come to the realization that 1) plant foods are not necessary for health in daily doses for many people, and 2) in the natural world they are all only available on a seasonal basis outside the tropics, and thus, not available year round.
