ABSTRACT
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. We hypothesized that walnut-containing meals would mitigate post-meal increases in glucose, insulin, triglycerides, and lipid peroxidation while increasing TAC compared to the traditional meal without nuts. Furthermore, we hypothesized that the BW meal would exhibit greater TAC and subjective fullness while mitigating postprandial increases in lipid peroxidation better than the EW. This was a randomized, double-blind control crossover study in 30 healthy adults with three testing visits. At each visit, subjects consumed either the control, BW, or EW meal. Blood draws and visual analog scale appetite ratings were obtained at fasting, 30, 60, 120, and 180 min postprandially. The BW and EW meals resulted in greater suppression of appetite vs. control (Pâ¯<â¯.01 and Pâ¯=â¯.03, respectively), and the BW meal also increased fullness more than EW and control (Pâ¯<â¯.01 and Pâ¯<â¯.001, respectively). Finally, the BW meal also had a greater suppression of lipid peroxidation vs. control (Pâ¯=â¯.01). There were no other treatment differences in the other measures of appetite or for glycemia, triglycerides, or total antioxidant capacity. Substituting butter in a breakfast meal with BW or EW increased fullness; however, the BW meal was superior for suppressing overall appetite while also lowering postprandial lipid peroxidation.
