Metabolomic Profiles of Plasma Retinol-Associated Dyslipidemia in Men and Women.

Studies of both animals and humans show that a high intake of vitamin A is associated with a lower risk of dyslipidemia. However, an association of plasma retinol levels with dyslipidemia is unclear. Therefore, the aim of this study is to investigate an association between plasma retinol and dyslipidemia and to identify related metabolites and pathways in the general population.

Characterization of dietary patterns and assessment of their relationships with metabolomic profiles: A community-based study.

Background & Aims: Determining dietary patterns in China is challenging due to lack of external validation and objective measurements. We aimed to characterize dietary patterns in a community-based population and to validate these patterns using external validation cohort and metabolomic profiles.

Design: We studied 5145 participants, aged 18-80 years, from two districts of Hangzhou, China.

Multiplicity and complexity of food environment in China: full-scale field census of food outlets in a typical district.

Objectives: Community food environment is closely associated with residents' health status, and it has received substantial research attention in recent years. However, such studies are sparse in China. This study aims to reveal the characteristics of food environment in China.
