Description
This study examined the effect of consuming pinto, black, and dark red kidney beans with white rice in comparison to a white rice only control meal on the glycemic response of adults with type 2 diabetes (T2D). These bean and rice combinations are part of many traditional diets. Seventeen subjects with T2D treated by diet and/or metformin were randomly assigned to 4 treatments: white rice (control), pinto beans/rice, black beans/rice, and dark red kidney beans/rice. All treatments were portioned by weight and matched for available carbohydrate content of ∼ 50 grams. Capillary whole blood samples were collected at baseline and at 30, 60, 90, 120, 150 and 180 minutes posttreatment and assessed for glucose concentration using the YSI Stat Plus Analyzer. Net change glucose responses were significantly lower for the pinto, black, and dark red kidney bean and rice meals than control at 90, 120 and 150 minutes posttreatment (P < 0.05). Incremental area under the curve (iAUC) values were also significantly reduced for the bean/rice meals containing pinto (P < 0.01) and black beans (P < 0.05) in contrast to the rice control. Results suggest that the combination of whole beans and rice may be beneficial to those with T2D to assist with blood glucose management.

Description
Background: The shortage of available dietetic internship (DI) positions for qualified applicants threatens the future of dietetics. Only about half of all applicants will obtain a slot. Additional internship positions are needed and can be offered only if more practitioners become preceptors. Objective: To examine the perceptions associated with the role of DI preceptor among nutrition and dietetic practitioners and identify barriers and motivators to becoming a DI preceptor in Arizona. Design: An online survey adapted from previous published instruments was administered between July and September 2011 to dietetic and nutrition professionals eligible to precept dietetic interns. Participants: RD, DTR, and school food service professionals on file with Arizona registries were invited to participate in the survey. A total of 675 subjects participated in the study. Statistical analyses performed: Chi-square analysis was used to assess differences between preceptors and non-preceptors for categorical variables. Independent t-tests were used to analyze differences between groups for continuous variables. Results: Respondents included 314 current or former preceptors and 361 non-preceptors with no significant differences in gender, age, or race between groups. Preceptors typically perceived the preceptor role more favorably than non-preceptors. Non-preceptors reported fewer benefits and more disadvantages to being a preceptor. Only 18% of non-preceptors knew how to become a mentor. Conclusions: Motivators for practitioners to become preceptors and continue in the role include personal benefits, dedication to the role and profession, and contributions to the workplace by interns. Barriers to mentoring interns include lack of compensation, increased workload, lack of support, lack of training, lack of resources, intern liability, and lack of knowledge of how to become a preceptor. Results of the study can be used to target barriers and emphasize benefits associated with the preceptor role to encourage participation in the preceptor process to make more internship positions available.
