| Glycemic responses (two hour tolerance test) of buckwheat bread containing buckwheat and oat flour and control bread containing oat flour only were measured in clinical studies according to FAO/WHO recommendations noticing the recent improvements in the methods; A standard evening meal (supper) was be provided for each test person for the nights before tests, and test persons got exact orders for the exercise on the test morning. Test persons (10) fasted 8-12 hours before each test. They ate a portion of bread or glucose containing 50 g available carbohydrates. The GI values of buckwheat bread and control bread will be shown in poster. The preliminary results of six test persons show that buckwheat bread has a slower but longer lasting glycemic... |

| Demand for organic foods is partially driven by consumers' perceptions that they are more nutritious. However, scientific opinion is divided on whether there are significant nutritional differences between organic and non-organic foods, and two recent reviews have concluded that there are no differences. In the present study, we carried out meta-analyses based on 343 peer-reviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods. Most importantly, the concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods, with those of phenolic acids, flavanones, stilbenes, flavones, flavonols... |

| Health effects of Northern berries have been studied intensively already for years. Different berries show different health effects. Beneficial effects have been found in weight management, glucose metabolism, liver and eye health, immune function, oxidative metabolism (cancer prevention) and lipid metabolism. However, results of different studies are unanimous due to differences in test materials (whole berries / different berry fractions) and methods (in vitro studies, cell studies, animal studies, clinical studies). Especially human studies are still rare. |
