Lipopolysaccharides

Lipopolysaccharides (LPS) are a component of Gram-negative bacteria (e.g. bacteroides) that have been implicated in triggering low grade inflammation. Reducing Gram-negative bacteria (by increasing Gram-positive strains; i.e. bifidobacteria and lactobacilli) may therefore reduce inflammation. Fibre such as fructooligosaccharides (FOS) and galactooligosaccharides (GOS) increases Gram-positive strains of bacteria, especially bifidobacteria, and regular consumption may therefore be beneficial to the health.
