New insights into the relationship between sweet taste of sugar and satiety regulation

To date, very little is known about how sweetness perception contributes to satiety. This study, conducted by an Austrian-German team led by chemists Veronika Somoza and Barbara Lieder, provides new insights into the relationship between the sweet taste of sugar, energy intake and the regulatory process of hunger and satiety.
