Science Daily — If you eat the right grains for breakfast, such as whole-grain barley or rye, the regulation of your blood sugar is facilitated after breakfast, lunch, and dinner. It was previously not known that certain whole-grain products have this effect all day.
This is due to a combination of low GI (glycemic index) and certain type of indigestible carbohydrates that occur in certain grain products. The findings are presented in a dissertation from the Faculty of Engineering at Lund University. The dissertation shows that even people who have had a breakfast low in GI find it easier to concentrate for the rest of the morning.
Great variations in levels of blood sugar are being associated more and more with the risk of old-age diabetes, obesity, and cardiovascular diseases. These findings can therefore provide valuable information for tailoring a new generation of whole-grain products with low GI that can counteract these so-called lifestyle diseases. They may also have a beneficial effect on short-term memory and mental acuity.
"It is known that a carbohydrate-rich breakfast with low GI can moderate increases in blood sugar after lunch. But my results show that low GI in combination with the right amount of so-called indigestible carbohydrates, that is, dietary fiber and resistant starch, can keep the blood-sugar level low for up to ten hours, which means until after dinner," says Anne Nilsson, a doctoral student at the Unit for Applied Nutrition and Food Chemistry and author of the dissertation.
