Formulation of Carbohydrate-Electrolyte Beverages

David R. Lamb1

INTRODUCTION

The optimal formulation of carbohydrate-electrolyte beverages for the soldier in the field is an important consideration for the health and combat effectiveness of that soldier. This is especially true for soldiers who are exposed to thermal stress that leads to rapid dehydration and for those who are undergoing prolonged physical exertion that leads to both rapid dehydration and exhaustion. The combination of thermal stress and physical exertion makes beverage formulation even more critical. In this paper it is assumed that the role of the beverages in question is to replenish depleted body fluid stores for the purpose of minimizing dehydration and to supply carbohydrates for the purpose of forestalling exhaustion. Furthermore, the emphasis in this paper is on the role played by rates of gastric emptying and intestinal absorption associated with various beverage formulations in determining the efficacy of those formulations.
