The sweet and the salad,then the sour and the bitter. One century ago Kikunae Ikeda, Professor of the Chemical in the Imperial University of Tokio, isolated the glutamic acid as amminoacid responsable of Umami, the sense of ‘tasty’.
A study of Washington University School of Medicine, which has involved 21 people , has recently discovered the presence of a proteic receptive group in the tongue, the CD36, which would transmit the sensation of ‘fat’. Hyperactivity or ipoactivity of such protein would determine, as well as, the greater or the smaller sense of satiety in front of high levelled lipidic foods: to find a way to increase the receptivity of CD36 could be an arrow to the fight of obesity.
