This study aims to explore the association between 19 types of dietary fatty acids and gallstone disease using large-scale population data, assess the correlation between dietary fatty acids and serum fatty acids, and investigate the causal relationship between plasma lipids and gallstone disease from a genetic perspective.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We employed a cross-sectional study design, combined with logistic regression analysis to evaluate the association between dietary fatty acids and gallstone disease.

The correlation between dietary fatty acids and serum fatty acids was weak, but the intake of eicosatetraenoic acid (20:4) showed a positive correlation with serum levels of arachidonic acid (ARA). Mendelian randomization analysis revealed a protective relationship between plasma lipids containing ARA (20:4) and gallstone disease and identified two SNPs in the FADS1 gene(rs174533 and rs174537)associated with gallstone disease.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Our study identifies a significant association between ARA intake and reduced gallstone risk, underscoring its potential in gallstone prevention. The weak correlation between dietary and serum fatty acids suggests complex physiological regulation mechanisms. Mendelian randomization analysis establishes a protective causal link between specific plasma lipids containing ARA and gallstone disease, highlighting the genetic underpinnings of gallstone formation. This research provides a foundation for dietary interventions and underscores the importance of genetic factors in lipid metabolism for future gallstone research and clinical management.

Societal adaptation, however, has lagged, and likely explains some of the psychosocial comorbidities of neurodiversity, as individuals are forced to adapt their personality and how they display their emotions to fit societal norms. There remains a lack of awareness and understanding of neurodiversity amongst the healthcare professions.

Here, we use a case study, focusing on attention deficit hyperactivity disorder to explore the relationship between neurodiversity and work from the perspective of a neurodiverse health care professional.
