Glucose tolerance, non-nutrient drink, and gastrointestinal hormones

Nonruminant Nutrition Symposium: nutrient and non-nutrient sensing and signaling in the gastrointestinal tract.

The immediate postweaning period represents a critical time point in the health and development of the young pig. Often a lag in growth is observed, which can be compounded by enteric pathogen challenges. The importance of adequately meeting the nutritional needs of the newly weaned pig has been the focus of numerous papers. Postweaning changes in diet often result in decreased intake and reduc...

Gastrointestinal Hormones: Introduction and Index

Serum lipid profiles, total tract nutrient digestibility, and gastrointestinal tolerance by dogs of α-cyclodextrin.

The objectives were to quantify gastrointestinal tolerance, total tract nutrient digestibility, and serum lipid profiles of dogs as affected by α-cyclodextrin (ACD) supplementation and to validate the accuracy of fat analyses techniques using novel ACD-fat complexes. The ACD was hydrolyzed and free sugars and hydrolyzed monosaccharides were quantified using high performance liquid chromatograph...

Gut hormones in gastrointestinal disease.

Considerable advances have been made in the understanding of the physiology of gut hormones. Thus, knowledge of the mechanisms of release and of the actions of many of the hormones is rapidly expanding. The known clinical importance of gut hormones is at present confined only to the excess production of gastrin, VIP, and pancreatic glucagon by endocrine tumours. The role of these three and the ...

Gastrointestinal function during exercise: comparison of water, sports drink, and sports drink with caffeine.

Caffeine is suspected to affect gastrointestinal function. We therefore investigated whether supplementation of a carbohydrate-electrolyte solution (CES) sports drink with 150 mg/l caffeine leads to alterations in gastrointestinal variables compared with a normal CES and water using a standardized rest-exercise-rest protocol. Ten well-trained subjects underwent a rest-cycling-rest protocol thre...
