“…More recent studies published after the release of this meta‐analysis revealed comparable results. In 2016, Lee et al reported the effects of a brown rice‐based vegan diet on glycemic control in patients suffering from T2D and noted a statistically significant HbA1c reduction of −0.9% in participants with high compliance . In 2017, Ramal and colleagues paired a plant‐based diet low in fat and high in fiber with lifestyle support in the treatment of Latinos with T2D who live in medically underserved areas .…”

Atrial fibrillation is the most prevalent cardiac arrhythmia in the clinical setting affecting approximately 34 million individuals worldwide. The disease is associated with a significant burden of morbidity and mortality resulting from stroke, heart failure, and acute coronary syndrome. Atrial fibrillation is now a major public health problem with tremendous implications on the economy and the world's healthcare systems. Numerous risk factors and clinical conditions that are associated with the development and progression of atrial fibrillation have been identified in the past. Within the last decades, a shift in awareness toward modifiable conditions has been observed and risk factor management has gained significant momentum. In light of this, dietary approaches are of paramount importance. Whole‐food plant‐based diets emphasizing grains, legumes, vegetables, fruits and nuts and excluding most (or all) animal products have recently experienced a significantly increased interest. The purpose of this review is to present evidence suggestive of a plant‐based diet being a valuable tool in atrial fibrillation risk factor management. The effects of a plant‐based diet on both established and emerging risk factors, such as inflammation and subclinical atherosclerosis, are reviewed in this article. A special focus is put on cardiovascular and metabolic risk factors including hypertension, coronary artery disease, diabetes, and obesity.

“…7 When 50 g of WR, corresponding to one-third of the daily intake, is replaced by BR, the risk of developing type 2 diabetes is reduced by 16%. 8 However, it may be difficult for people to continue eating BR on a daily basis due to its taste and texture, even though BR could prevent or improve diabetes compared with WR.…”

Eating glutinous brown rice twice a day for 8 weeks improves glycemic control in Japanese patients with diabetes mellitus

et al. 2017

Objective:We recently reported that eating glutinous brown rice (GBR) for 1 day improved the whole-day glucose profile and postprandial plasma glucose level compared with eating white rice (WR) or standard brown rice. However, it was unknown whether eating GBR could maintain improvement of glycemic control for a longer period. Therefore, we evaluated the effect of GBR intake for 8 weeks on glycemic control in outpatients with diabetes mellitus.Methods:This was an open-label randomized crossover study in outpatients with type 2 diabetes. Among the 18 subjects registered in this study, 2 were excluded from analysis. After a 1-week observation period while eating WR twice a day, the patients were randomly assigned to two groups. One group ate GBR as a staple food twice a day for 8 weeks and then switched to WR for the next 8 weeks, while the other group ate WR first and then switched to GBR. A mixed meal tolerance test was performed at baseline and after 8 and 16 weeks of dietary intervention to evaluate plasma glucose and serum C-peptide.Results:None of the subjects failed to complete the study because of disliking the taste of GBR. Hemoglobin A1c (7.5–7.2%, P=0.014) and glycoalbumin (20.4–19.4%, P=0.029) both decreased significantly when the patients were eating GBR. Additionally, the 30-min postprandial plasma glucose level (194–172 mg dl−1, P=0.031) and the incremental area under the concentration vs time curve of serum C-peptide (31.3–22.1 ng min ml−1, P=0.023) during the mixed meal tolerance test were also decreased significantly by intake of GBR. In contrast, there were no changes of glycemic control during the WR period.Conclusions:We confirmed that GBR was well tolerated for 8 weeks and improved glycemic control in patients with type 2 diabetes.

“…Additionally, the follow‐up to the 2006 RCT by Barnard et al, which tested an energy‐controlled diet compared to an ad libitum vegan diet and initially found within‐group but not between‐group advantages for both diets, found a substantial decline in benefits occurring between 22 and 74 weeks; however, when the data were analysed before medication changes, a significant between‐group reduction in HbA1c was observed in the vegan group . In a review by Rinaldi et al whose conclusions favoured plant‐based diets, six trials did not consistently show improvements in glycaemic control, weight loss or CVD risk factors . The ADA also cited a commentary based on a non‐systematic review, a cross‐sectional study, and an assessment of diets in Barnard et al 2006.…”

“…We identified nine studies not included in the ADA review, three of which were published after the 2018 standards (Table S4). Three RCTs found reductions in HbA1c from baseline, and two found the test diet superior compared to the control diet . In these studies, the plant‐based diets were compared to an energy‐restricted diet, the recommended Korean Diabetes Association diet, and the participants' usual diet.…”

Aims The global rate of type 2 diabetes (T2D) continues to rise. Guidelines that influence the worldwide treatment of this disease are central to changing this trajectory. We sought in this review to evaluate the appropriateness of sources cited in the American Diabetes Association's (ADA) guidelines on eating patterns for T2D management, identify additional relevant sources, and evaluate the evidence. Materials and Methods We reviewed the evidence behind the ADA's recommendations on eating patterns in the 2018 and 2019 ADA Standards of Care and the 2014 ADA Nutrition Therapy Recommendations for Adults with Diabetes. Additionally, we conducted a comprehensive search to identify any additional studies not included in the cited evidence. To determine appropriateness of inclusion in the guidelines, the following criteria were applied: 1) it was a clinical trial or systematic review/meta‐analysis of clinical trials; 2) it involved persons with T2D; 3) one of the study arms followed one of the eating patterns currently recommended; 4) its reported outcomes included glycaemic control; 5) outcomes were reported separately for persons with T2D. Results We found a wide variation in the evidence for each eating pattern. Issues that have hampered the guideline process include: lack of a rigorous literature review, resulting in the omission of pertinent studies; an overreliance on prospective cohort studies; inconsistent standards for evidence; inclusion of studies not on persons with T2D; and bias. Conclusions The ADA Guidelines recommended eating patterns fall short of rigorous standards of scientific review according to state‐of‐the‐art systematic review and guideline creation practices.
