Scientists have come up with a "healthy" chocolate in which fat has been replaced with water.
The low-fat chocolate, which contains almost two thirds water, apparently tastes identical to regular bars, reports The Telegraph.
Besides chocolates, boffins are also developing a low-fat mayonnaise and porridge which prevents people from feeling hungry by staying in their stomach longer.
University of Birmingham scientists claimed that they could replace a normal chocolate bar's fat particles with calorie-free substances such as water, air or gels.
The team created the "water-chocolate" by then connecting water particles with cocoa butter crystals.
The bar, which contains about 60 per cent water, was found to have the same taste, smell and feel in a person's mouth.
"It is possible that small, stable, air bubbles designed to resemble oil droplets in terms of their size and physical properties could be used to produce a new generation of low fat foods," said Dr Philip Cox, who led the research.
