Sixteen healthy adults were recruited for participation in the study. Three interventions of four days each were conducted. For two days subjects were fed a polyphenol-free diet. On the third day fasting blood was collected and then the subject was given breakfast with either pecans providing 75% of energy or a control diet. The remaining 25% of energy came from a refined carbohydrate source. Pecans were either in the form of a smoothie or as whole pecans. Four blood samples were drawn throughout the morning followed by a polyphenol-free lunch. Two more blood samples were drawn in the afternoon followed by a polyphenol-free dinner. Urine was also collected throughout the day. On the fourth day fasting blood was drawn and the subjects were served a normal breakfast.
