Dr Hans-Peter Kubis, of the University of Bangor, said the dulling of tastebuds can lead to a vicious cycle as consumers of sugary drinks tend to more sweet and calorie-laden food to compensate.

　　He said: This has serious implications for public health. This research shows how little sweet food stuffs are required to actually change your taste perceptions, and how powerful sweet-tasting products are.

　　We are heading for a health disaster with rising obesity levels and the increasing incidence of type 2 diabetes. From our research it is clear to see how this situation may have created a cycle of sweet food and drink consumption. As taste satisfaction levels drop; the more sweet foods are consumed, contributing to these problems.
