Fruit sugar for global energy.

If various types of fresh ripe fruits (mangoes, peaches, dates, wolfberries, elderberries) were squeesed for fruit juice then by cold process the juice was stripped of most of its sugar using nano-filtration, centrifuge, condensing or whatever, then the resultant reside would be the basis of super nutritious food for everone and the discarded sugar could be used for powering bacterial fuel cells. The production scope would include particular nutrient concentrates depending on the choice of fruit species and the extraction processes could be refined to allow lowest antigenic value plus highest anabolic value for food anywhere.
