function and immune inflammation in healthy adults.
function and immune inflammation in healthy adults.
28 healthy men and women (age 18-35 years old) will be recruited to participate in a 16-week
randomized crossover study. Upon enrollment, all subjects will enter a 4-week run-in egg-free
period where they will refrain from consuming any egg-based foods (Period 1). Subjects will
then enter the first intervention period, where they be randomly assigned to consume either 3
whole eggs/day or the equivalent amount of egg white-based egg substitute/day for 4 weeks
(Period 2). Afterwards, subjects will enter a 4-week washout period where egg-based foods are
restricted (Period 3), followed by a second intervention period, where they be assigned to
the alternative whole egg- or egg white-based treatment for 4 weeks (Period 4). Subjects will
come to the Department of Biology at Fairfield University every two weeks to check-in, and to
pick up their egg products during the intervention periods. Subjects will be asked to
maintain their normal diet and physical activity practices throughout all periods of the
study. Subjects will complete 5-day dietary records and physical activity logs at the end of
each study period.
