The good news is that type 2 diabetes is largely preventable. About 9 cases in 10 could be avoided by taking several simple steps: keeping weight under control, exercising more, eating a healthy diet, and not smoking.
Critical thinking and research. Critical thinking is a core competency for evidence based general practice and an essential precursor to research. It is also essential for evaluating and understanding the implications of research for clinical practice.
No single method or type of research is best in all situations. Give enough information about the methods so that other researchers could reproduce or replicate the study. Evaluate alternative explanations for the findings. Submit to a process of review by other knowledgeable researchers (peer review).
