• Resumen

  • This study aimed to investigate the acute effect of 100 grams of germinated brown rice (GBR) intake on plasma glucose and insulin, serum levels of peptide YY (PYY) and neuropeptide Y (NPY), as well as appetite perception in healthy subjects compared to white rice (WR). Compared to WR (p < .05, all), serum NPY was lower at 60 minutes and 120 minutes after GBR ingestion and further decreased after 120 minutes (p < .05) compared to the baseline levels. Neither GBR nor WR had any effect on PYY, glucose, or insulin levels. Decreased hunger and increased fullness after ingestion were reported in both instances but did not differ between the rice types. In conclusion, we revealed novel evidence that GBR decreased serum NPY levels, while both GBR and WR decreased hunger and increased the perception of fullness. These results suggest that GBR might slow down the subjects’ appetites through the NPY effect.
