Summary

Walnuts are a nutrient dense food, but most health research is on English walnuts (EW). Black walnuts (BW) contain a different antioxidant and fatty acid profile, and more protein, compared to EW. The purpose of the study was to compare postprandial responses following the consumption of 3 breakfast meals containing either butter (control), BW, or EW.

Detailed description

This study was a randomized, double-blind control trial consisting of 3 study visits for 3 different treatments. The treatments were high-fat breakfast muffins containing either butter (control), black walnuts, or English walnuts. 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 walnut-containing meals would mitigate post-meal increases in glucose, insulin, triglycerides (TG), and lipid peroxidation while improving all measures of subjective appetite and TAC compared to the traditional meal without nuts.
