Metabolic Availability of Lysine From Rice

Application of the Indicator Amino Acid Oxidation Technique for the Determination of Metabolic Availability of Lysine From Cooked Rice Protein in Adult Men

The purpose of this study is to investigate the digestibility of the amino acid lysine in cooked rice in adult men using stable isotope technique.

The investigators objective is to determine the metabolic availability (MA) of lysine in cooked white rice protein using the indicator amino acid oxidation (IAAO) technique. Five men will receive graded levels (20, 40, and 60, and 70%) of the lysine requirement of 35 mg/kg/d as a crystalline AA mixture,and cooked rice protein (20, 40 and 60%), respectively.

Inclusion Criteria:

• Healthy Adult males (18 to 50years old)

Exclusion Criteria:

• A history of recent weight loss or illness
• Use of any medication at the time of entry into the study.
