Grow your own, add tons of minerals to your life.
Marlie and I have this kind of nice system you might want to imitate in one form or another.
She decided to do the wheat grass thing and pulled out this old hand grinder she'd bought at a yard sale. We started to use it and it's great: quiet, and you can run the stuff through a couple of times and you can do apples and carrots and if you want and understand how super charged with nutrition they are, various edible weeds like mallow and pigweed and dock and lamb's quarters and purslane. ( Except purslane is so yummy, that if you have it, you'll want to throw it right in your salad or your mouth).
Then we discovered in our reading up on raw foods that juicers that press like the hand ones and some very expensive mechanical ones, get the highest percentage of good stuff out of the whatever you add, and they product a juice that oxidizes far slower than either that of masticating juicer ( like Champion), which in turn, is better than the centrifugal juicers.
So, it's quiet.
We get more goodies.
The juice oxidizes (much, much) slower.
Okay, here's the cool part. Reading in Body Electronics (see link in sidebar of WakeUp Feldenkrais site), I re-discovered how important chelated minerals are, which is to say, minerals that aren't just the chemicals, but are bound in plant form.
A light bulb went off: PLANT THE WHEAT BERRIES ( we sprout our own), IN SOIL THAT'S GOOD LOTS OF MINERALS.
SO WE ADD GROUND UP OYSTER SHELLS AND ORGANIC KELP TO EACH TRAY OF SOIL
So, voila, we are getting gobs of chelated minerals without paying a big batch that you would to get them in a bottle.
Anyway, try this if you want. Hand juicers can be ordered via Wheat Grass Kits. Scroll down to look at four manual juicers.
