Brief Summary:
This study will evaluate how much of the essential amino acid lysine school-aged children are using for protein synthesis when consuming different cereal grains. Six healthy children between 6-10y will be recruited. They will be given cooked white rice, corn, oats, black beans, and milk. Using a minimally invasive technique, the amount of lysine that is available from cereal grain products will be determined. With the results from this research project accurate diet recommendations will be developed for children consuming cereal-based diets.

Arm Intervention/treatment
Experimental: Lysine metabolic availability
Lysine metabolism from pure amino acids and cereal foods in children.
Dietary Supplement: L-Amino Acid
8 different lysine intakes (L-Amino Acid and food) will be tested for 8 hours each.




Primary Outcome Measures :
  1. 13 CO2 production [ Time Frame: 8 hours (1 study day) ]
    Breath samples will be collected during the study day, to measure the rate of oxidation of tracer phenylalanine in the expired breath.


Secondary Outcome Measures :
  1. Urinary lysine [ Time Frame: 8 hours, 2 samples at the beginning and end of the study day. ]
    Urine will be collected during the study day to measure urinary excretion of lysine.
