n = 27. Values are means ± SDs unless otherwise indicated. No difference was found between the randomly assigned groups at the beginning of the study (2-sample independent t tests). AD, adequate dairy product intake; HD, high dairy product intake; OGTT, oral-glucose-tolerance test.
Prediabetes is characterized by altered fasting glucose and/or glucose intolerance (23).
