Does ingestion of carbohydrate, protein, or fat increase cardiac output and superior mesenteric arterial flow compared to water in young, healthy persons?
Energy-containing meals, regardless of macronutrient composition, significantly increase cardiac output and splanchnic blood flow in healthy individuals.
Waaler et al. (1992) studied Healthy (n=5). Fluid meals containing carbohydrate, protein, or fat vs. Water only was evaluated on Changes in cardiac output and superior mesenteric arterial flow. Ingestion of 4 MJ meals containing carbohydrate, protein, or fat caused marked increases in cardiac output and superior mesenteric arterial flow compared to water.
