Sweet tooth: nature of nurture?

Does reduced exposure to sweetness induce a lower preference for sweet items, reduce sugar and energy intake and, perhaps, also body weight? Proving if this is true, or not, is the goal of the Sweet tooth project.

In this project which studies the effect of 6 months dietary sweetness exposure to sweetness preferences, food intake, glucose homeostasis and body weight this topic is addressed to find out whether or not the statement is correct.

The study focusses on the effects of a low, regular and high sweet ad libitum diet on changes in sweetness preferences as primary outcome measure. Secondary outcome measures include changes in sweetness perception, energy intake, glucose metabolism and body weight. In the 6-month nutrition intervention study with follow-up the subjects are provided with foods that comprise more than 50% of their energy requirements.

The scientific control of this study and its output is under the supervision of a steering committee consisting of fully independent renowned experts from some European universities and research institutions, a Dutch public health institution and a medical charity fund.
