The effect of macrobiotic Ma-Pi 2 diet on systemic inflammation in patients with type 2 diabetes: A post hoc analysis of the MADIAB trial Andreea Soare, Rossella Del Toro, Elena Roncella, Yeganeh Manon Khazrai, Silvia Angeletti, et al. BMJ Open Diabetes Research and Care, 2015 Introduction Current guidelines for the management of type 2 diabetes (T2D) emphasize diet as essential therapy. However, the effect of diet on systemic inflammation remains unclear. We investigated the effects of consuming a macrobiotic Ma-Pi 2 diet versus a standard recommended diet (control diet) on markers of inflammation in patients with T2D. Methods This was a post hoc analysis of the MADIAB trial, a 21-day randomized controlled trial conducted in 51 patients (25 males and 26 females) with T2D. Patients were randomized 1:1 to the Ma-Pi 2 macrobiotic diet or a control diet based on dietary guidelines for T2D. Biological antioxidant potential of plasma and circulating levels of high-sensitivity C reactive protein, interleukin-6, tumor necrosis factor-α, and insulin-like growth factor-1 were assessed. Results After 21 days on the Ma-Pi 2 or control diet, markers of inflammation were reduced in both groups. The antioxidant potential of plasma improved significantly in the Ma-Pi group. A significant reduction in insulin growth factor-1 was observed in the Ma-Pi group versus control group (p<0.001). Conclusions Findings of this post hoc analysis demonstrated that the Ma-Pi 2 diet is a safe dietary strategy to reduce levels of the markers of insulin resistance and inflammation, compared with baseline values, in the short term. Furthermore, the Ma-Pi 2 diet was superior to the control diet in reducing insulin growth factor-1 and may be beneficial for patients with T2D.

Multiple dietary supplements do not affect metabolic and cardiovascular health Andreea Soare, Edward P. Weiss, John O. Holloszy, Luigi Fontana Aging, 2014 Dietary supplements are widely used for health purposes. However, little is known about the metabolic and cardiovascular effects of combinations of popular over-the-counter supplements, each of which has been shown to have anti-oxidant, anti-inflammatory and pro-longevity properties in cell culture or animal studies. This study was a 6-month randomized, single-blind controlled trial, in which 56 non-obese (BMI 21.0-29.9 kg/m2) men and women, aged 38 to 55 yr, were assigned to a dietary supplement (SUP) group or control (CON) group, with a 6-month follow-up. The SUP group took 10 dietary supplements each day (100 mg of resveratrol, a complex of 800 mg each of green, black, and white tea extract, 250 mg of pomegranate extract, 650 mg of quercetin, 500 mg of acetyl-l-carnitine, 600 mg of lipoic acid, 900 mg of curcumin, 1 g of sesamin, 1.7 g of cinnamon bark extract, and 1.0 g fish oil). Both the SUP and CON groups took a daily multivitamin/mineral supplement. The main outcome measures were arterial stiffness, endothelial function, biomarkers of inflammation and oxidative stress, and cardiometabolic risk factors. Twenty-four weeks of daily supplementation with 10 dietary supplements did not affect arterial stiffness or endothelial function in nonobese individuals. These compounds also did not alter body fat measured by DEXA, blood pressure, plasma lipids, glucose, insulin, IGF-1, and markers of inflammation and oxidative stress. In summary, supplementation with a combination of popular dietary supplements has no cardiovascular or metabolic effects in non-obese relatively healthy individuals.
Wrist circumference: An independent predictor of both insulin resistance and chronic kidney disease in an elderly population Adina Mitrea, Andreea Soare, Simona Georgiana Popa, Mirela Nicoleta Tudor, Maria Mota, et al. Romanian Journal of Diabetes Nutrition and Metabolic Diseases, 2013 Background and aim: It was recently reported that wrist circumference is associated with insulin resistance (IR) both in children and adults. We aimed to evaluate whether wrist circumference is a useful anthropometrical parameter for the evaluation of IR in an elderly population. Material and method: We performed a study on 40 subjects, 20 with type 2 diabetes (T2D) and 20 control subjects. IR was evaluated using the homeostasis model assessment of insulin resistance (HOMA-IR). We measured the following anthropometrical parameters: weight, height, waist circumference (WC), hip circumference, wrist circumference, waist to hip ratio (WHR), waist to height ratio (WHtR), body mass index (BMI) and body adiposity index (BAI). Results: We found statistically significant differences between the subjects with T2D and the control group for all the analyzed parameters. Statistically significant correlations between all the anthropometrical parameters and HOMA-IR were observed. However, only WC was an independent predictor of IR. Wrist circumference was the only parameter negatively correlated with the estimated glomerular filtration rate (eGFR). Furthermore, this measurement was an independent predictor of chronic kidney disease (CKD) in the studied subjects. Conclusion: Wrist circumference can be used in the general practice as a surrogate marker of IR in the elderly, being both easily determined and a cost-free method
