Juice Beneficial, Fruit Neutral?


Hi. I was just wondering why the O Diet guidelines suggest black cherry juice and pineapple juice as being beneficial, but suggest the black cherry and the pineapple fruit to be neutral. What is it about the juice that would make it more beneficial than the fruit itself? Aren't the juices a more concentrated source of sugar? Thanks so much for your time and thought.


They are also a more concentrated form of the phytonutrient (in the case of black cherry juice, the anthrocyanidins and other alkaline elements; in pineapple the proteolytic enzymes). It would take a considerably greater amount of the fruit to match the levels often found in the juice (and in the case of pineapple, perhaps a mouth sore or two.)

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.
