The association of PUFAs with all-cause, cardiovascular, and ischemic heart disease (IHD) mortality in patients with CVD was prospectively evaluated using restricted cubic splines and Cox proportional risk models.</p></div><div><h3>Results</h3><p>Among the 35,096 participants, 3,786 fatalities occurred.

Drawing on evidence from two co-creation case studies conducted with small-scale informal fruit and vegetable vendors and poor consumers in Vietnam and Nigeria from January 2020 to December 2021, we explored the relevance of bottom–up community-engaged co-creation processes in intervening within LMICs’ food retail environments. Employing a mixed-methods approach that includes quantitative surveys, qualitative interviews, participatory workshops, and focus group discussions, we demonstrated that bottom–up co-creation processes involving marginalized socioeconomic groups can generate retail-level innovations that are tailored to informal retail contexts, whereas remaining aligned with established top–down theories and literature pertaining to food environments and healthy diets. We provided empirical evidence highlighting how both vendors and consumers respond positively to the co-created innovations. Expanding upon our results, we offered methodological insights applicable to interventions targeted at food environments in LMICs, and considerations for future research or development initiatives in this domain. Our findings revealed the capacity of vulnerable stakeholders to actively engage in public health initiatives and contribute to developing innovative solutions that are context-specific and conducive to the adoption of healthier dietary practices.

This has contributed to an increased emphasis on the declaration and management of conflicts of interest (CoI) in the reporting, evaluation, and application of research in nutrition science. However, common perceptions of CoI in nutrition, and procedures for declaring and managing these, often lack intellectual rigor and consistency. This commentary highlights 3 main issues related to CoI in nutrition, particularly the emphasis on industry-related CoI relative to other sources of conflict and bias. <em>1</em>) Considerations of CoI in nutrition are largely limited to financial or collaborative links to the food industry, disregarding other important sources of influence such as intellectual allegiances or nonindustry financial and professional incentives. <em>2</em>) Associations with industry incur <em>ad hominem</em>, often punitive stigmatization of individuals and their research, and inappropriate downgrading or exclusion of evidence. This disproportionately affects expertise in the food and agricultural sciences, in which commercial collaborations are widely encouraged. <em>3</em>) These practices and related approaches to managing CoI are applied without due consideration of the nature of the conflicts and activities involved, the qualifications of individuals, or the availability of other, objective methods and guidance for assessing research quality and risks of bias. Overall, recognition of the nature and range of CoI in nutrition and approaches to their identification and management lack consistency and balance.
