Carbohydrate ingestion, effect

Other studies indicate that sucrose does not cause hyperactivity. Carbohydrate ingestion increases levels of serotonin (5-hydroxytryptamine), a brain neurotransmitter that promotes relaxation and sleep. Dietary sucrose should theoretically have a calming effect and reduce activity, manifestations which have been observed in case studies (63). To date, clinical investigations have failed to show a significant connection between sucrose consumption and aggressive or dismptive behavior (66). 

In this paper we will discuss the anatomy of the fluid spaces in the body, the fluid shifts and losses during exercise and their effects on performance, and thirst and drinking during exercise with comments on carbohydrate ingestion.

Gastric acid secretion is inhibited in the presence of acid itself. A negative feedback occurs when the pH approaches 2.5 such that further secretion of gastrin is inhibited until the pH rises. Ingested carbohydrates and fat also inhibit acid secretion after they reach the intestines several hormonal mediators for this effect have been proposed. The secretion of pepsinogen appears to parallel the secretion of H+, while the patterns of secretion of mucus and bicarbonate have not been well characterized.
