Purpose: An increased risk of gastric cancer (GC) for pickled vegetables intake has been suggested, but a complete understanding of its pathogenic origin is still lacking, especially from a metabolic viewpoint. We investigated the plasma metabolites and metabolic pathway alteration of GC related to pickled vegetables intake.
Methods: We analyzed plasma samples collected from 365 gastric cancer patients and 347 healthy individuals, and divided them into three subgroups according to the intake of pickled vegetables. Plasma samples were detected by untargeted metabolomics.
Results: Nine metabolites were significantly altered in GC patients among pickled vegetables intake groups (FDR value<0.05). All of them were associated with the risk of gastric cancer adjusted for gender, age, smoking status, infection. Pathway analysis showed significant alteration in the folate biosynthesis pathway.
Conclusion: In short, we provide new insights from a metabolic perspective on the relationship between pickled vegetables intake and the occurrence of gastric cancer.

Background: Plant-based diets may protect against cognitive impairment; however, observational data have not been consistent.
Objective: This study aimed to evaluate the association between plant-based dietary patterns and cognitive function.
Methods: The study recruited 937 participants who were asked to complete food frequency questionnaires to assess the quality of their plant-based diets using the overall plant-based diet index (PDI), the healthful PDI (hPDI), and the unhealthful PDI (uPDI).

Bashang suancai is one of the most wellknown traditional fermented vegetables in North China. The study examined the variations in bacterial diversity, physicochemical properties, and volatile flavor compounds (VFCs) of Bashang suancai over a 7-day fermentation period, utilizing Illumina NovaSeq sequencing and headspace solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). The leading bacterial phyla were , , and , while the predominant bacterial species included , , , , and .

However, the deep utilization and development of carrots and their derived products are limited in numerous countries, with a particular deficiency in advanced deep-processing and transformation technologies. Consequently, the value of carrot products is diminished and resources are wasted.

The effects of brine acidification, glutamate addition, and starter culture on γ-aminobutyric acid (GABA) content of fermented cucumber were investigated. GABA is a nonprotein amino acid with antihypertensive, antianxiety, and immunomodulatory properties. It is produced during cucumber fermentation but is limited by the low intrinsic concentration of free glutamate.

Purpose: Vitamin D supplementation positively impacts anemia, but the relationship between a ferritin-related dietary pattern, iron parameters, and vitamin D in anemia is unclear.
Methods: This cross-sectional study analyzed data from the 2017-2019 National Nutrition and Health Survey, including 1423 pregnant women over 15 years old. Dietary intake was assessed using a semi-quantitative food frequency questionnaire and a 24-hour dietary recall.
