It has been postulated that the shape of the intake distribution can have a significant impact on estimates of inadequacy. The “nutritional intake functions for R” (“nutriR”) package has been developed to address this.</div></div><div><h3>Objectives</h3><div>This study aimed to assess the impact of assuming the “best-fit” shape of nutrient intake distributions (using nutriR) on prevalence estimates of inadequate nutrient intake, as compared with observed nutrient intake distributions with the EAR cut-point or PA method.</div></div><div><h3>Methods</h3><div>A cross-sectional dietary intake survey was conducted among 443 Ivorian school-aged children (6–12 y) by 24-h recall, with nonconsecutive repeats for 13% of the population. Six methods to estimate the prevalence of intake inadequacy for 11 nutrients were compared: methods 1–3 used single 24-h recall data to either apply the <em>1</em>) EAR cut-point method, <em>2</em>) the PA method, or <em>3</em>) the nutriR method; and methods 4–6 applied the same methods after correction for within-person variation using the Statistical Program to Assess Usual Dietary Exposure, which generates estimates of usual daily nutrient intake.</div></div><div><h3>Results</h3><div>Nutrient intake distributions were right skewed (skewness average 1.0, range: 0.4–2.0) and showed large variation (coefficient of variation average 40%, range: 20%–60%). The prevalence estimates of inadequate nutrient intake were similar across all methods, with a mean difference of ±5 percent point (range: 0–27 percent point). The smallest mean differences, 0.4 and 0.3 percent points, were observed with usual intake data between nutriR and EAR cut-point (method 6 compared with 4), and nutriR and PA (method 6 compared with 5), respectively. Larger differences (∼12 percent point) were observed when comparing single 24-h recall data (methods 1–3) with usual intake (methods 4–6).</div></div><div><h3>Conclusions</h3><div>Assuming nutrient intake distributions with the shape of “best-fit” to the observed intake distribution did not affect prevalence estimates of nutrient inadequacy in this population of Ivorian school children.</div><div>This study was registered at <span><span>clinicaltrials.gov</span><svg><path></path></svg></span> as NCT06175130.</div></div>","PeriodicalId":16620,"journal":{"name":"Journal of Nutrition","volume":"155 7","pages":"Pages 2449-2458"},"PeriodicalIF":3.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144142797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, we have reported that a high protein glycation level impairs protein digestion, thereby compromising lysine bioavailability. The lower postprandial lysine availability may restrict the anabolic properties of a high glycated protein.</div></div><div><h3>Objectives</h3><div>The objective of this study was to assess the impact of milk protein glycation on postprandial plasma amino acid availability and subsequent postprandial muscle protein synthesis rates during recovery from a single bout of resistance-type exercise.</div></div><div><h3>Methods</h3><div>Forty-five recreationally active, healthy young males participated in this double-blinded, randomized parallel study. After performing a single bout of whole-body resistance-type exercise, subjects ingested 20 g milk protein with either a low (4%; LOW-GLYC) or high (47%; HIGH-GLYC) glycation level or a noncaloric placebo (PLA). Continuous intravenous infusion of L-[<em>ring</em>-<sup>13</sup>C<sub>6</sub>]-phenylalanine was combined with the collection of blood and muscle tissue samples during a 6-h postprandial period to assess plasma amino acid concentrations and muscle protein synthesis rates.</div></div><div><h3>Results</h3><div>Protein ingestion increased plasma total and essential amino acid concentrations compared with placebo (time × treatment interaction: <em>P</em> &lt; 0.001), with no differences between the low and high glycated milk protein. Plasma lysine availability, assessed over the full 6 h postprandial period, was substantially lower following ingestion of the protein with the high versus low glycation level (−5 ± 7 compared with 10 ± 9 mmol · L<sup>-1</sup> · 360 min, respectively, <em>P</em> &lt; 0.001). Postprandial muscle protein synthesis rates did not differ between treatments (0.059 ± 0.016, 0.061 ± 0.012, and 0.061 ± 0.018 % · h<sup>-1</sup>, in LOW-GLYC, HIGH-GLYC and PLA, respectively, <em>P</em> = 0.939).</div></div><div><h3>Conclusions</h3><div>Ingestion of protein with a higher glycation level attenuates postprandial plasma lysine availability.
