First and foremost, I would like to say thank you to Dr. Bowers for sparking an interest in me by introducing me to the Fetal Origins of Adult Disease Hypothesis. Thank you, Dr. Hicks, for encouraging all of us graduate students to choose a thesis topic that we found interesting. Thank you, Dr. Wohlt, for your class discussions on nutrition and culture. I would also like to thank my family for their support throughout this process. I would like to give a special thank you to my husband, Andy, who encouraged me to keep going when I felt like giving up.
