Over the past two decades, the prevalence of diabetes in the U.S. has nearly doubled. Half of U.S. adults 20 years or older have either diabetes (12%) or prediabetes (35%). One third of Koreans have diabetes (12.7%) or prediabetes (25%). The Diabetes Control & Complications Trial (DCCT) demonstrated that well-controlled blood glucose could prevent or delay microvascular complications in people with type 1 diabetes. There was also a reduction in all-cause mortality with well-controlled glucose levels. Randomized clinical trials have consistently demonstrated that type 2 diabetes can be prevented or delayed among people at high-risk of diabetes by lifestyle interventions; healthy diet, regular exercise, weight reduction. National and local community nutrition and lifestyle education programs for diabetes and prediabetes are provided in the U.S. However, participants have been reporting difficulty understanding and following the nutritional education guidelines. A simple, easy to follow program was developed and tested for faith community nurses in 2015 by the author for her Doctor of Nursing Practice project at the University of Illinois at Chicago. To be more effective and inclusive for non-medical people, this project was revised as a 6-week community nutrition and lifestyle program for people with diabetes, prediabetes, and obesity - “7 ways to reduce postmeal blood glucose spikes”. In this presentation, the testimonial results that occurred during the workshops will be reported. Three changes that reduced postmeal blood glucose will be presented: (a) how a 3-meals-and-3-snacks pattern changed people’s eating habits so they became sated with small frequent meals and lost weight; (b) how to estimate and control food portions easily by using simple hand measurement techniques; and (c) how much blood glucose levels dropped after a 15-minute postmeal walk.
