Measures of Dietary Fat and Energy Absorption in Healthy Adults.

ABSTRACT:

Objectives

Existing reference ranges for stool fat and energy absorption were developed using subjects in controlled environments on precise diets. This study measured energy and fat absorption in healthy, community-dwelling adults eating a moderate-to-high fat American diet via stool- and serum-based methods.

Methods

This was a secondary analysis of healthy subjects recruited as the comparison group in a chronic pancreatitis study. Subjects recorded dietary intake and collected stool over 3-day periods. Stool was analyzed for fat content using the coefficient of fat absorption and for energy content using bomb calorimetry. The malabsorption blood test (MBT) was used to measure dietary fat absorption.

Results

Nineteen subjects had mean daily stool measures of 143 g we
