The present invention relates to a method of assessing the propensity of a
plant, if consumed, to contribute to the onset and/or progression of
diabetes in a mammal and, more particularly, to a method of assessing the
propensity of a tuberous vegetable, if consumed, to contribute to the
onset and/or progression of diabetes in a mammal. The method of the
present invention is useful, inter alia, for identifying mammals at risk
of developing diabetes based on dietary intake. The present invention is
further directed to methods of assessing the risk status of an individual
for development of diabetes. The present invention still further provides
methods for the prophylactic and/or therapeutic treatment of diabetes.
