The BBC reports:
A smoothie advert which claimed the fruit drink could rid the body of toxins has been criticised by the industry watchdog.
Manufacturers Innocent said the antioxidants in one smoothie were the equivalent of the recommended five daily portions of fruit and vegetables.
However, the Advertising Standards Authority (ASA) decided it didn’t have the evidence to back that claim.
In newspaper adverts, it claimed: “we blended acai with equally incredible pomegranates and blueberries to produce a recipe that contains even more antioxidants than the average five a day.”
However, the ASA ruled that neither the detoxifying, nor the antioxidant claim stood up to close scrutiny.

“Water undoubtedly is the most important chemical substance in the world,” explained Elmar Fuchs and colleagues from the Graz University of Technology in Austria in a recent study. “The interaction of water with electric fields has been intensely explored over the last years. We report another unusual effect of liquid water exposed to a dc electric field: the floating water bridge.” When exposed to a high-voltage electric field, water in two beakers climbs out of the beakers and crosses empty space to meet, forming the water bridge. The liquid bridge, hovering in space, appears to the human eye to defy gravity.
Upon investigating the phenomenon, the scientists found that water was being transported from one beaker to another, usually from the anode beaker to the cathode beaker. The cylindrical water bridge, with a diameter of 1-3 mm, could remain intact when the beakers were pulled apart at a distance of up to 25 mm.
