摘要
The gastrointestinal immune system is crucial for overall health, safeguarding the human body against harmful substances and pathogens. One key player in this defense is dietary fiber pectin, which supports the gut's immune barrier and fosters beneficial gut bacteria. Pectin's composition, including degree of methylation (DM), RG-I, and neutral sugar content, influences its health benefits. This review assesses how pectin composition impacts the gastrointestinal immune barrier and what advantages specific chemistries of pectin has for metabolic, cardiovascular, and immune health. We delve into recent findings regarding pectin's interactions with the immune system, including receptors like TLRs and galectin 3. Pectin is shown to fortify mucosal and epithelial layers, but the specific effects are structure dependent. Additionally, we explore potential strategies for enhancing the gut immune barrier function. Understanding how distinct pectin chemistries affect the gastrointestinal immune system is vital for developing preventive and therapeutic solutions for conditions related to microbiota imbalances and immune issues. Ultimately, this review offers insights into strategies to boost the gut immune barrier's effectiveness, fostering better overall health by using specific pectins in the diet.
