Pages

Abstract

 Objectives: This study set out to determine the association between Dietary intakes at lunch and postprandial Peptide YY 3-36 (PYY3-36) 90-120 minutes after the consumption of lunch meal. Materials and Methods: In the present cross-sectional study, the subjects (n = 176) were asked to eat their lunch at work on the test day. The postprandial concentration of PYY3-36 was measured 1. 5 to 2 hours after the consumption of lunch meal. Results: The subjects within the age range of 25 to 39 and those with ages less than 25 (P = 0. 005) indicated the highest and the lowest levels of PYY3-36, respectively. Postprandial PYY3-36 had a direct significant association with fat content at lunch (P = 0. 049) and had an inverse association with cholesterol (P = 0. 001), docosahexaenoic acid (DHA) (P = 0. 040) and eicosapentaenoic acid (EPA) (P = 0. 022). Moreover, polyunsaturated fatty acids (PUFAs) and linoleic acid at lunch indicated a significant positive correlation with PYY3-36 (r = 0. 182, P = 0. 016 for both). Furthermore, a significant negative correlation was detected between energy intake at dinner and post-lunch PYY3-36 (r =-0. 216, P = 0. 004). Protein (OR [odds ratio] = 0. 390, 95% CI: 0. 160-0. 950) and fat intake (OR = 2. 697, 95%CI: 1. 103-6. 594) at lunch, energy intake at dinner (OR = 0. 298, 95% CI: 0. 127-0. 702), and energy spent to perform physical activities after lunch (OR = 0. 411, 95% CI: 0. 182-0. 929) significantly predicted the serum concentration of post-lunch PYY3-36. No significant association was found between PYY3-36 and Glycemic index and load. Conclusions: There was a significant association between Dietary intakes at lunch meal and post-lunch serum concentration of PYY3-36. Further large-scale cross-sectional researches and randomized controlled trials are needed to confirm the mentioned results.
