Measurement of Dietary Lipid Oxidation in Toddlers - a Method Study

The purpose of this research is to measure how toddlers burn fat after drinking milk that has some fat molecules that can be tracked based on how heavy they are. These molecules are not dangerous. By collecting several urine samples throughout a 24-hour window (about 7 urine samples or more) after drinking the fat molecules, we will be able to measure how fast your toddler is sending out (excreting) these samples in the urine. This will tell us how fast your toddler is using fat for energy. This will also help determine the best urine collection schedule for studies using this technology.
