As Kate Wood pointed out when I went to her workshop, it's just sugar and water. It's brilliant for cleansing, but not for the re-building you need.
Does Ms. Wood have a background in nutritional science? I have found that many raw leaders do not know much in this regard and have gone with their preference and research like any one of us here does. Everyone knows that fresh-off-the-tree fruits are amazingly rich in nutrients that also rebuild our bodies, and due to the greater digestive ability, I'm sure those nutrients are better assimilated.
But, I do recognize that a lot of sweet fruit does not do me well unless I exercise like crazy beforehand. I always think we should go with how we best feel (with inner knowing and our body's reactions, of course), so if more good fats are great for people (and I find citrus is so lovely in a diet with extra fats), then good!
