This study will employ a 2-arm, double-blind, randomized, crossover design. Each arm will consist of one test day and will differ in the type of oil incorporated in the test breakfast: test blend 3.2 or corn oil. Oil sequence will be randomized. Each test day will follow the same protocol and will be separated by at least two weeks for boys or 4 weeks for girls to ensure that testing occurs during the same phase of their menstrual cycle for each test day.
