Familial resemblance in dietary intake among singletons, twins, and spouses: a meta-analysis of family-based observations.

Background: Familial dietary intake can be influenced by both genetic and environmental factors; the current study aimed to examine the role of these two factors on dietary intake by investigating the resemblance in energy, nutrient, and food group intake among spouses and siblings in twin and family-based studies.

Methods: The online literature databases, including PubMed, Scopus, Web of Science, and Cochrane Library were systematically searched up to September 2024. The pooled correlation coefficient (r) of studies was calculated using Fisher's z and standard error (SE) of z's of all studies and our final results were reported in six groups including non-twin siblings, monozygotic (MZ) twins, dizygotic (DZ) twins, all-twins, all siblings, and spouse.

Assessment of the anti-inflammatory and anti-glycemic properties of Royal Jelly and Tocotrienol-rich fraction in an experimental study: Does irisin mediate these effects?

Irisin, a novel adipomyokine, has been proposed to be a therapeutic agent against obesity-related metabolic disease. Royal Jelly (RJ) and tocotrienol-rich fraction (TRF) are suggested to promote obesity and its related problems through potential mutual mechanistic pathways. This investigation intended to evaluate the glycemic and inflammation-promoting effects of RJ, TRF, and their combinations to evaluate their synergic effects through irisin action in obese rats induced by a high-fat diet (HFD) that underwent a calorie restriction diet (CRD).

Trend analysis, gender-specific patterns, and age dynamics of childhood and adolescent obesity: insights from the Tehran lipid and glucose study.

Background: Childhood and adolescent obesity pose significant challenges to global health, with escalating prevalence and associated short- and long-term health consequences. This longitudinal study leveraged data from the Tehran Lipid and Glucose Study (TLGS) to investigate the trends of obesity among Tehranian children and adolescents over a 21-year period.

Methods: Utilizing data from TLGS phases I to VII (1999-2021), we included 3845 participants aged 3-18 years at the beginning of phase I.
