“…In the case of carbohydrates for example, the system would have to involve interoceptors specifically sensitive not only to glucose, but also to su crose. For these respond differently, as was shown in our previous studies (4,5), and corroborated by others (7,12,16).…”

The present study records a rise of amylase activity in rat pancreatic tissue after a long-term administration of high carbohydrate diets (14 % excess of glucose administered orally or subcutaneously as 30 % glucose solution) in comparison to a normal diet. It was concluded that the pancreas obtains information on intestinal food composition along the humoral pathway. Electron microscopic investigations revealed no impairment of the acinar cells of the pancreas, but only changes that may be considered as a structural expression of the various phases of activity of the acinar cells.

“…Ingestion of digestible carbohydrates, such as monosaccharides or starch, has been reported to affect α amylase activity in the pancreas in rats. 28,29) On the other hand, α amylase activity in the rat pancreas was not affected by the digestible carbohydrate contents, even when it was changed from 10 to 60% of the diets. 30) α Amylase content and synthesis reached at maximum when dietary carbohydrate was 60 to 70% of the total energy contents.…”

Carbohydrates in food are digested by hydrolytic enzymes in the lumen of the small intestine. α Amylase in the pancreatic juice and disaccharidases on the brush border membranes in the small intestine are the main enzymes for the digestion of dietary carbohydrates. The activity of hydrolytic enzymes on carbohydrates and their regulation by dietary components has already been reviewed in detail for the pancreas 1,2) and the small intestine. 3,4) Pancreatic α amylase first cleaves internal α 1,4 bonds in polysaccharides and produces maltose, maltotriose and maltotetraose in upper portion of the lumen in the small intestine. The second stage of carbohydrate digestion occurs on the surface of intestinal epithelial cells in microvillous membrane. Several glycosidases, or disaccharidases, hydrolyze di or oligosaccharides derived from ingested carbohydrates to smaller saccharides. The final products of carbohydrate digestion are monosaccharides, which are then absorbed into the epithelial cell lining inner surface of the intestine. Aging, fasting and feeding conditions influence the activities of pancreatic α amylase 1,2) and intestinal disaccharidases. 3,4) Characteristics of the ingested carbohydrates also have a significant effect on pancreatic α amylase 5,6) and intestinal disaccharidase activities. 7,8) Certain types of diet were reported to affect both pancreatic α amylase and intestinal disaccharidases at the same time. 9,10) Carbohydrates are the main energy source and are usu
