Data are mean ± SEM.
No statistically significant difference noted between conditions for kilocalories (p = 0.83), protein (p = 0.99), carbohydrate (p = 0.84), fat (p = 0.43), vitamin C (p = 0.91), vitamin E (p = 0.58), or vitamin A (p = 0.41).
Values are for the 24 hour period immediately preceding each test condition.
