High dietary intake of prebiotic inulin-type fructans in the prehistoric Chihuahuan Desert.

چکیده
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 years. Ancient cooking features, stable carbon isotope analysis of human skeletons, and well-preserved coprolites and macrobotanical remains reveal a plant-based diet that included a dietary intake of about 135 g prebiotic inulin-type fructans per d by the average adult male hunter-forager. These data reveal that man is well adapted to daily intakes of prebiotics well above those currently consumed in the modern diet.

Inulin-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 ...

Background and Objective: There is a high prevalence of chronic diseases such as type 2 diabetes in most populations. Therefore, interest in use of functional foods for the control of such diseases is of importance. The present study was designed to compare the effects of inulin and oligofructose-enriched inulin on glycemic indices and blood pressure in women with type 2 diabetes. Materials and...
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(-...
