Article Abstract
Gut health is intricately linked to energy homeostasis, stress resistance, inflammation, and longevity. Methionine (Met) intake significantly influences gut health, with both supplementation and restriction showing distinct effects. While appropriate Met supplementation offers benefits, excessive intake can be harmful, whereas Met restriction appears to improve overall health of the body, especially the gut. This review synthesizes research on Met's role in gut health, highlighting its metabolism, interactions with the intestinal microbiota, and effects on oxidative stress, inflammation, and permeability in the intestine. The possible reason for Met intake influences the risk of metabolic diseases such as obesity, diabetes, cardiovascular disease, and cognitive impairment, thus influencing lifespan was explored, which is potentially via gut health. In addition, strategies for achieving precision nutrition of Met, including dietary adjustments, production of Met-specific foods, bioengineering plant strains, and methioninase supplementation, were proposed. These insights aim to deepen the understanding of Met's effects on gut health and guide interventions for improving health outcomes.

Background: Intestinal cells receive incoming signals from neighboring cells and microbial communities. Upstream signaling pathways transduce these signals to reach transcription factors (TFs) that regulate gene expression. In inflammatory bowel disease (IBD), most single nucleotide polymorphisms (SNPs) are in non-coding genomic regions containing TF binding sites.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Esophageal cancer (EC) is one of the most serious health issues around the world, ranking seventh among the most lethal types of cancer and eleventh among the most common types of cancer worldwide. Traditional therapies-such as surgery, chemotherapy, and radiation therapy-often yield limited success, especially in the advanced stages of EC, prompting the pursuit of novel and more effective treatment strategies. Immunotherapy has emerged as a promising option; nonetheless, its clinical success is hindered by variable patient responses.

Background: Dietary fiber supports metabolic health via microbial fermentation, producing short-chain fatty acids (SCFAs). However, metabolic responses to fiber vary between individuals, potentially due to differences in gut microbiota composition. The Prevotella-to-Bacteroides (P/B) ratio has emerged as a potential biomarker for fiber responsiveness.
