Recent studies have revealed that various food components affect the immune response. These components act on various immune cells, and their effects are mediated through the intestinal immune system and, in some cases, the intestinal microbiota. In this review, we describe the immunomodulating effects of various food components, including probiotics, prebiotics, polysaccharides, vitamins, minerals, fatty acids, peptides, amino acids and polyphenols. Some of these components enhance immune responses, leading to host defense against infection, whereas others inhibit immune responses, thus suppressing allergy and inflammation...

Irritable bowel syndrome (IBS) is a common, heterogeneous disorder characterized by abdominal pain associated with changes in bowel habits. The pathogenesis of IBS is multifactorial and may relate to alterations in the gut microbiota, changes in visceral sensation and motility, and genetic and environmental factors. Administration of systemic antibiotics may increase the risk of IBS by altering gastrointestinal homeostasis. Therapeutic interventions for IBS with diarrhea that are thought to target alterations in the gut microbiota include the nonsystemic antibiotic rifaximin, the medical food serum-derived bovine immunoglobulin, prebiotics, probiotics, and dietary modification...

Xylooligosaccharides (XOS) and arabinoxylooligosaccharides (AXOS) were produced from the insoluble arabinoxylan fraction of pretreated wheat bran by endoxylanases. The glycoside hydrolase (GH) family 10 xylanases GsXyn10A from Geobacillus stearothermophilus and RmXyn10A-CM from Rhodothermus marinus produced the AXOS A 3 X, A 2 XX and A 2 + 3 XX in addition to XOS. RmXyn10A-CM also produced XA 2 + 3 XX due to its non-conserved aglycone region accommodating additional arabinose substitutions in subsite +2. The GH11 enzymes, Pentopan from Thermomyces lanuginosus and NpXyn11A from Neocallimastix patriciarum had minor structural differences affecting hydrogen bonds in subsites -3 and +3, with similar hydrolysis profiles producing XA 3 XX as major AXOS and minor amounts of XA 2 XX but different ratios of X 3 /X 2 ...

Martin H Floch
With the advent of the scientific realization that the microbiota of the gastrointestinal tract was more than the cells that exist in the body, the full importance of prebiotics and probiotics has come forth. The importance has been stressed and is available in the new textbook entitled, "The Microbiota in Gastrointestinal Pathophysiology: Implication for Human Health, Prebiotics, Probiotics and Dysbiosis." There is enough evidence now published in the literature so that the scientific world now believes that prebiotics and probiotics are important in gastrointestinal disease...

Nutritional strategies have been explored as primary or adjunct therapies for inflammatory bowel disease (IBD). Exclusive enteral nutrition is effective for the induction of remission in Crohn disease and is recommended as a first-line therapy for children. Dietary strategies focus on adjusting the ratio of consumed nutrients that are proinflammatory or antiinflammatory. Treatments with dietary supplements focus on the antiinflammatory effects of the individual supplements (eg, curcumin, omega-3 fatty acids, vitamin D) or their positive effects on the intestinal microbiome (eg, prebiotics, probiotics)...

Diet has shaped microbiota profiles through human evolution. Traditional gut microbiomes are described to be driven by high levels of Prevotella. In the present, however, it is consistently described a lower microbial richness in urban industrialized populations compared with individuals living in rural settings, Bacteroides being predominant among urban-industrial gut microbiomes. Components of diet are highly influential in shaping the gut microbiota, being fiber, fat, proteins, polyphenols and micronutrients differentially metabolized by generalist and specialized microorganisms alone or through the phenomenon of cross-feeding...

Early nutrition may have long-lasting metabolic impacts in adulthood. Even though breast milk is the gold standard, most infants are at least partly formula-fed. Despite obvious improvements, infant formulas remain perfectible to reduce the gap between breastfed and formula-fed infants. Improvements such as reducing the protein content, modulating the lipid matrix and adding prebiotics, probiotics and synbiotics, are discussed regarding metabolic health. Numerous questions remain to be answered on how impacting the infant formula composition may modulate the host metabolism and exert long-term benefits...
