As the produce on the fruit and vegetable shelves of supermarkets becomes less and less nutritious, what can we do to keep our bodies healthy? Why are these foods so poorly nutritious? Many products, especially those "out of season", come from hydroponics: the small plants are raised on blocks of synthetic fibers, such as glass or mineral wool, and placed on huge mobile tables and fed by drops. drip by chemicals according to their computer-determined needs. These plants can be strawberries, lettuce, tomatoes or cucumbers, among others. They are cheap to produce but contain no nutrients and have no taste unless they have a synthetic flavor added to them.
