Acute Consumption of Pecan-enriched Meal

Comparison of Metabolic and Antioxidant Responses to a Breakfast Meal With and Without Pecans

Pecans are a nutrient-dense food, but it is unknown whether substituting pecans for a portion of the butter in a traditional breakfast meal improves post-meal responses.

This study was a randomized, double-blind control trial consisting of 2 study visits for 2 different treatments. The treatments were high-fat breakfast muffins containing either butter (control) or pecans. The investigators recruited healthy, normal-weight adults between the ages of 15 and 45y. Study visits were completed in a random order with at least 72 hours between each visit. Anthropometrics, questionnaires, and fasting and postprandial blood samples were collected at each visit.

Hypothesis: The pecan-enriched meal will blunt the post-meal increase in glucose, insulin, triglycerides (TG), and lipid peroxidation while improving all measures of subjective appetite and TAC compared to the traditional meal without nuts.
