Germinated brown rice (GBR) has been suggested as an alternative approach to mitigate highly prevalent diseases providing nutrients and biologically active compounds. In this study, the content of γ-oryzanol, γ-aminobutyric acid (GABA), total phenolic compounds (TPC) and antioxidant activity of soaked (for 24 h at 28 °C) and GBR (for 48 and 96 h at 28 °C and 34 °C) were determined and the effect of sun-drying as an economically affordable process was assessed. Germination improved the content of GABA, TPC and antioxidant activity in a time-dependent manner. Sun-drying increased γ-oryzanol, TPC and antioxidant activity, whereas GABA content fluctuated depending on the previous germination conditions. This study indicates that sun-drying is an effective sustainable process promoting the accumulation of bioactive compounds in GBR. Sun-dried GBR can be consumed as ready-to-eat food after rehydration or included in bakery products to fight non-communicable diseases. ; This work has received financial support from the project AGL2013-43247R from Ministerio de Economia y Competitividad (Spain) and European Union through FEDER Programme.

The effects of diet supplementation with ?-tocopherol acetate (VE) and selenium yeast (SeL) on the water holding capacity (WHC), cooking weight loss (CL), drip loss (DL), pH, colour and selenium concentration of the breast of chickens fed diets based on corn or brown rice were studied. From 21 days of age, a total of 200 birds were housed in 38 floor pens (experimental unit) in a randomised 23 factorial arrangement. The levels of supplementation were VE (0 and 200 mg/kg), organic selenium (0 and 0.3 ppm) and two diets (100% corn and 100% brown rice) in a total of eight treatments: T1) corn + 0 SeL + 0 VE (control); T2) corn + 200 mg/kg VE + 0 SeL; T3) corn + 0 VE + 0.3 ppm SeL; T4) corn + 200 mg/kg VE + 0.3 ppm SeL; T5) brown rice + 0 VE +0 SeL; T6) brown rice + 200 mg/kg VE + 0 SeL; T7) brown rice + 0 VE + 0.3 ppm SeL; T8) brown rice + 200 mg/kg VE + 0.3 ppm SeL. The concentration of selenium in the breast increased with VE supplementation in the diet (P < 0.001). However, a positive interaction between VE and SeL on selenium concentration in the meat was found (P = 0.06). A better WHC with the inclusion of SeL and VE was found only in the rice-based diets. The replacement of corn by brown rice decreased (P < 0.05) the yellowness of the meat. CL and DL were not significantly affected by the treatments. Broilers fed with SeL supplemented diets showed a higher pH in the breast than diets without supplementation. In conclusion, the interaction between VE and SeL increased selenium in meat but improved WHC only in rice-based diets. The replacement of corn by brown rice decreased the yellowness of chicken breast meat.

India has the second largest number of people with diabetes in the world following China. Evidence indicates that consumption of whole grains can reduce risk of type 2 diabetes. This manuscript describes the study design and methods of a trial in progress evaluating the effects of substituting whole grain brown rice for polished (refined) white rice on biomarkers of diabetes risk (glucose metabolism, dyslipidemia, inflammation). This is a randomized controlled clinical trial with a crossover design conducted in Chennai, India among overweight but otherwise healthy volunteers aged 25–65y with a body mass index ≥23kg/m2 and habitual rice consumption ≥200grams/day. The feasibility and cultural appropriateness of this type of intervention in the local environment will also be examined. If the intervention is efficacious, the findings can be incorporated into national-level policies which could include the provision of brown rice as an option or replacement for white rice in government institutions and food programs. This relatively simple dietary intervention has the potential to substantially diminish the burden of diabetes in Asia and elsewhere.
