Nutrient effects: post-absorptive interactions

摘要

After a meal, the metabolic fuel selection at the whole-body level depends on the plasma concentrations of nutrients such as glucose, non-esterified fatty acids (NEFA), amino acids, and on hormonal responses. Over the last 10 years, there has been great interest in studying the metabolic effects following the ingestion or the intravenous (i.v.) infusion of the three macronutrients, carbohydrate (CHO), fat, and protein (or amino acids for i v infusion). The aim of the present brief review is to summarize the main mechanisms which determine the post-absorptive interactions between the nutrients.
