Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Surgery is a stress on the body and recovering well after surgery is very important to patients and their doctors. It is therefore important to prepare patient's bodies for the stress of surgery, and one way to do this is to provide proper nutrition. In the past, patients were asked to prepare for surgery by fasting from midnight before surgery. Today, it is known that this practice is not beneficial to patient's recovery. In fact, it has been recognized that drinking a sugary beverage (e.g., juice) before surgery stimulates the production of insulin, which is a hormone that helps make the proteins needed for wound healing after surgery. This is currently practiced at the MUHC. It might also be beneficial, however, to drink a beverage that contains sugar and whey proteins (a protein isolated from milk) before surgery. In fact, whey proteins stimulate insulin and may also have the added benefit of improving muscular strength. In this study, investigators will measure the level of insulin produced after drinking a carbohydrate (i.e., sugar)-whey protein beverage to determine how it compares to the level of insulin produced after drinking the sugary beverage used at the MUHC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is hypothesized that the increase in plasma insulin following a mixed carbohydrate whey protein drink is significantly greater than that elicited by a carbohydrate drink.

Carbohydrate

Patients in this arm will drink a 425 mL 100% clear apple juice (carbohydrate 50 g, 700 mOsmol). 1.5 g of acetaminophen will be dissolved in the beverage for determination of gastric emptying.
