High dietary intake of prebiotic inulin-type fructans in the prehistoric Chihuahuan Desert.
Archaeological evidence from dry cave deposits in the northern Chihuahuan Desert reveal intensive utilisation of desert plants that store prebiotic inulin-type fructans as the primary carbohydrate. In this semi-arid region limited rainfall and poor soil conditions prevented the adoption of agriculture and thus provides a unique glimpse into a pure hunter-forager economy spanning over 10 000 yea...
متن کاملInulin-type fructans: functional food ingredients.
A food (ingredient) is regarded as functional if it is satisfactorily demonstrated to affect beneficially 1 or more target functions in the body beyond adequate nutritional effects. The term inulin-type fructans covers all beta(2<--1) linear fructans including native inulin (DP 2-60, DP(av) = 12), oligofructose (DP 2-8, DP(av) = 4), and inulin HP (DP 10-60, DP(av) = 25) as well as Synergy 1, a ...
متن کاملIntroducing inulin-type fructans.
Inulin is a generic term to cover all beta(2-->1) linear fructans. Chicory inulin is a linear beta(2-->1) fructan (degree of polymerisation (DP) 2 to 60; DPav=12), its partial enzymatic hydrolysis product is oligofructose (DP 2 to 8; DPav=4), and by applying specific separation technologies a long-chain inulin known as inulin HP (DP 10 to 60; DPav=25) can be produced. Finally, a specific produc...
متن کاملInulin-type fructans of longer degree of polymerization exert more pronounced in vitro prebiotic effects.
AIMS We assessed to what extent fructans of different degrees of polymerization (DP) differ in their prebiotic effectiveness towards in vitro microbial communities from the proximal and distal colon. METHODS AND RESULTS Two short chain fructans - oligofructose (DP 2-20) and inulin (DP 3-60) - were administered to the Simulator of the Human Intestinal Microbial Ecosystem (SHIME) at 2.5 g day(-...
متن کاملPrebiotic inulin-type fructans induce specific changes in the human gut microbiota
OBJECTIVE Contrary to the long-standing prerequisite of inducing selective (ie, bifidogenic) effects, recent findings suggest that prebiotic interventions lead to ecosystem-wide microbiota shifts. Yet, a comprehensive characterisation of this process is still lacking. Here, we apply 16S rDNA microbiota profiling and matching (gas chromatography mass spectrometry) metabolomics to assess the cons...
