They are also nutrient dense and must still be balanced out with heart healthy protein foods such as nuts. Combining a starch with a higher protein food can slow the uptake of simple sugars and reduce the glycemic load. If you are a diabetic be very careful with portion size. Even low glycemic foods can inc glucose. ...Read more

Glucose starts out as a carbohydrate but is quickly stored as a fat. Rice and wheat are made up of more complex chains of carbohydrates with fewer simple sugars. The effect of these foods on raising blood sugar may not be as rapid as with simple sugar. Hope this helps:) ...Read more
Acid feedback loop: Gastrin is a hormone that responds to the amount of stomach acid produced--not enough acid causes gastrin levels to rise to stimulate acid production. Gastrin is suppressed when acid levels are adequate in normal patients. However, in those with hypersecretory states like zollinger-ellison syndrome, gastrin is continually produced in high concentration resulting in excess acid, diarrhea, ulcers. ...Read more
