The miracle berry from Africa... The berry makes sour things taste sweet Imagine an extract from a berry that would make sour things taste sweet and help you lose weight. Then imagine not being allowed to take it. The world is getting fatter. One billion people are overweight, and 300 million of those are clinically obese. The search is always on for replacements for those things that, eaten in excess, make us obese - fatty and sugary foods. There is no miracle pill that can replace either. Nearly four decades ago one man came close to providing a tablet that could reduce our love of sugar. In the 1960s, Robert Harvey, a biomedical postgraduate student, encountered the miracle berry, a fruit from west Africa which turns sour tastes to sweet.                                                          iPlayer "You can eat a berry and then bite into a lemon," says Harvey. "It becomes not only sweeter, but it will be the best lemon you've tasted in your life." More importantly, this "miracle" can be used to manufacture sweet tasting foods without sugar or sweeteners, which have always been plagued by an after-taste. http://news.bbc.co.uk/2/hi/7367548.stm http://www.localforage.com/local_forage/2007/04/natural_sweeten.html http://en.wikipedia.org/wiki/Synsepalum_dulcificum
