Background/aim: Total fat intake has an important impact on the low-density lipoprotein (LDL) peak particle diameter (LDL-PPD) and may interact with nutrient-sensitive single nucleotide polymorphisms (SNPs). The objective was to examine whether there is suggestive evidence of SNP × dietary fat intake interaction effects influencing the LDL-PPD in the Quebec Family Study (QFS) in order to generate hypotheses to be tested in larger studies.
Methods: SNPs from a genome-wide association study (GWAS) using Illumina Human610-Quad BeadChip, total fat intake derived from a 3-day weighted food record, and SNP × total fat intake interaction effects were examined on LDL-PPD in 541 QFS subjects.
Results: The GWAS analyses 29 identified independent SNP × total fat intake interaction effects on the LDL-PPD at p < 10(-5), including SNPs in the following genes: ABCG2, CPA3, FNBP1, KCNQ3, NBAS, NCALD, OPRL1, NKAIN2, SH3BGRL2, SOX5, and SUSD4.
Conclusions: This observational study suggests that multiple SNPs interact with dietary fat intake to influence variation in the LDL-PPD.

South Asia has high prevalence rates of type 2 diabetes (T2D). Until the 1990s, the prevalence of T2D within South Asia was low but much higher in the South Asian diaspora living abroad. Today, high prevalence rates of T2D are reported among those living in South Asia.

Background: Several studies have assessed the epidemiology of sarcopenia in Iran with conflicting results, but comprehensive information has remained limited. Therefore, we aimed to perform a systematic review and meta-analysis of the prevalence of sarcopenia and its associated factors among Iranian population.
Methods: We searched in Embase, PubMed, Scopus, and Google Scholar, as well as Persian databases including the Scientific Information Database and Magiran, from inception to 31 May 2024.

This cross-sequential study found that frequent intake of high-fat and high-protein foods was associated with higher odds of atopic dermatitis (AD). However, occasional intake across all three macronutrients significantly lowered AD odds, suggesting that moderation-not strict avoidance-may benefit AD management in allergic populations.

Background: The growth in obesity and rates of abdominal obesity in developing countries is due to the dietary transition, meaning a shift from traditional, fiber-rich diets to Westernized diets high in processed foods, sugars, and unhealthy fats. Environmental changes, such as improving the quality of dietary fat consumed, may be useful in preventing or mitigating the obesity or unhealthy obesity phenotype in individuals with a genetic predisposition, although this has not yet been confirmed. Therefore, in this study, we investigated how dietary fat quality indices with metabolically healthy obesity (MHO) or metabolically unhealthy obesity (MUO) based on the Karelis criterion interact with genetic susceptibility in Iranian female adults.

Background: Hippuric acid (HA), a host-microbe co-metabolite, normally derives from gut microbial catabolism of dietary polyphenols.
Objectives: We investigated the potential interplay between dietary polyphenols and gut microbiota on circulating HA levels, and examined the associations between serum concentrations of HA and cardiometabolic risk markers.
Methods: In a 1-year cohort of 754 community-dwelling adults, serum HA and its precursor [benzoic acid (BA)] and fecal microbiota were assayed using liquid chromatography-tandem mass spectrometry and 16S ribosomal RNA sequencing, respectively.
