The Effects of Nutrients and Hormones on Gut Function and
Nutrient Absorption

My research focuses on the effects of glutamine, the products of nutrient fermentation (short-chain fatty acids), and growth factors (IGF-I and growth hormone) on gut maturation and adaptation. A specific interest is whether IGF-I, which stimulates gut growth and enhances digestive activity, results in enhanced nutrient absorption.

The final area of research concerns the effect of dietary complex carbohydrates on mineral balance. The purpose is to determine if the feeding of complex carbohydrates to infants and children affects the bioavailability of dietary minerals and/or enhances endogenous losses of such minerals.
