To be fair, the founder was much more into stuff like kale juice and beet juice than orange juice. Stuff that isn't particularly nutritious when eaten raw and unprocessed.

You think the nutritional content of kale or beets increases when you juice them? Source?

Yes, because you're crushing up the cells and releasing the stuff our puny human guts can digest. Raw kale is mostly undigestible by humans unless you're willing to sit and chew on every leaf for a few minutes like a cow.

Unfortunately I'm having trouble finding the sources on this. All of this breathless superfood wankery is really polluting the search results.

The effort to eat a bushel of kale dwarfs the effort to drink 1.5 juiced bushels of kale.

Perhaps, though steamed or fried it'd probably fit on a single plate... and then you'd get the fiber, too.

Supposedly cooking kale will destroy most of its nutritional value.
