Dietary fibers are non-digestible polysaccharides functionally known as microbiota-accessible carbohydrates MACspresent in inadequate amounts in the Western diet. MACs are a main source of energy for gut bacteria so https://porque.cybercasal9b.info/articles6498-jenaw.php abundance and variety of MACs can modulate gut Dietary fibre is also known as composition and function. This, in turn, impacts host immunity and health. In preclinical studies, MAC-deprived diet and disruption of gut homeostasis aggravate the development of inflammatory diseases, such as allergies, infections, and autoimmune diseases. The present review provides a synopsis on the impact of a low-MAC diet on gut homeostasis or, more specifically, on gut microbiota, gut epithelium, and immune cells. In recent decades, the prevalence click to see more non-communicable diseases, such as allergies, autoimmune, and inflammatory diseases has increased drastically in Western lifestyle countries. Although largely unexplained, these increases are likely to have a strong environmental component 45. Dramatic lifestyle changes followed the industrial revolution, among which a nutritional transition from a traditional diet to the Western diet 6. This diet consists of heavily processed foods, rich in fat, sugar, protein, and a variety of additives, while remaining low in micronutrients and dietary fiber 7. While most nutrients are Dietary fibre is also known as in the duodenum during the digestion process, dietary fiber remains intact until it reaches the colon, which is inhabited by trillions of Dietary fibre is also known as known as the gut microbiota 89. Dietary fibers are complex carbohydrates of plant origin, broken down by specialized enzymes produced by gut bacteria but indigestible by the host They have recently been redefined as microbiota-accessible carbohydrates MACs and Dietary fibre is also known as the major energy source for colonic bacteria

Whole-grain and cereal fibre intakes were Dietary fibre is also known as with lower body mass index and total cholesterol, LDL cholesterol. For years, our research group has studied the hypocholesterolemic effect of algae, 18,52 whose dry matter residue is very rich in fibre. Sodium alginate, funoran, porphyran, and carrageenan interacted with dietary cholesterol to facilitate its excretion, while dietary agar was almost inactive.
Different effects on blood cholesterol levels were observed more recently after inclusion of Nori, Wakame, and Sea Spaghetti in restructured meats. Dietary fibre is also known as concerning the effects of dietary fibres on blood pressure are scarcer than those available on their effects on cholesterol levels, and little is known regarding the mechanisms involved at the present time.
It has been suggested that diet and in turn fibre by modifying concentrations of LDL and HDL affects arterial endothelia and smooth muscle modifying the arterial contraction tone.
This enzyme, in turn, contributes to the formation of angiotensin II, a powerful vasoconstrictor that induces formation of the hormones noradrenaline, aldosterone, and vasopressin also known as antidiuretic hormone, ADH.
Dietary fibres are usually associated with antioxidant source e. Moreover, the hypotensive effects of dietary fibres may be associated with the retention of minerals such as K and Mg in their matrix, 18 as some minerals have been related to blood pressure.
Our group also has reviewed the hypotensive properties of seaweeds. Those that clearly affect blood pressure include fucoidans, alginates and funorane, while glucoronoxyloramnan and porphyran displayed no significant effects at all. For the present review, the authors selected two meta-analyses, each of which considered several trials dealing with the effect of different types and amounts of Dietary fibre is also known as on blood pressure. Summary data are presented in table IV.
Streppel et al. Original articles published during 37 years were included in this meta-analysis table IV. Data were abstracted on fibre dose, fibre type, blood pressure changes, study design features, and study Dietary fibre is also known as characteristics. A random-effects model was used for meta-analysis.
The results of this meta-analysis indicate that an average dose of This metaanalysis concluded with the following recommendation sic "Increasing the intake of fibre in Western populations, where intake is far below recommended levels, may contribute to the prevention of hypertension".
Whelton et al. Using a standardized protocol, information was abstracted on study design, sample size, participant characteristics, duration of follow-up and change in mean blood pressure. The data from each study were pooled using a random effects model to provide an overall estimate of dietary fibre intake on blood pressure. On the average dietary fibre intake was associated with a significant 1. Significant decreases in both systolic Dietary fibre is also known as diastolic blood pressures were observed in patients with hypertension systolic blood pressure An intervention period of at least 8 weeks may be necessary to achieve the maximum reduction in blood pressure.
Maki et al. The authors followed a visit web page, double-blind, controlled clinical trial design. Blood pressure responses were not significantly different between groups. As previously commented, CVD is an inflammatory condition in which oxidative modifications of lipoproteins play a central role.
Dietary fibres could exert a protective effect by quenching or deleting free radicals, interchanging ions, counteracting the negative action of free radicals with antioxidant compounds associated with click at this page polysaccharide matrix. Anderson et al. Foods that are rich in dietary fibre, including fruits, vegetables, legumes and whole grain Dietary fibre is also known as, also tend to be a rich source of vitamins, minerals, phytochemicals, antioxidants and other micronutrients.
Population-based cohort studies 97,98 suggest that small increases in vitamin E intake are associated with significant reductions in CVD. According to Anderson et al. No significant effects were found on those biomarkers. Most effect of fibre can be ascribed to associate compounds such as polyphenols.
Thus, Lecumberri et al. After intragastric administration of the polyphenol-rich extract a fast and Dietary fibre is also known as amount of polyphenols was detected in blood. The absorption of polyphenols confers a significant, although transitory, increase of the serum antioxidant capacity minutes post-gavage.
Gómez-Juaristi et al. Our group has studied the effect of alga consumption on the arylesterase activity of growing rats.
These Dietary fibre is also known as increased the activity of AE click at this page young rats fed a diet with no supplementary cholesterol. AE activity also increased when the enzyme was standardized with relation to the HDL mass. Food consumption, furthermore, provides pleasurable feelings of satisfaction and wellbeing through the senses e. In addition, diet can positively affect Dietary fibre is also known as or various physiological functions and reduce disease risk.
The Scientific Concepts of Functional Foods in Europe: Consensus Dietary fibre is also known asgenerated by the European Commission on Functional Food Science Dietary fibre is also known as Europe FUFOSEsuggested sic that claims of "enhanced function" and "reduced risk of disease" may only be made when they are supported by scientific data including appropriate, validated markers of exposure, target function or an Dietary fibre is also known as endpoint.
Dietary fibre is also known as functional foods have been obtained by including different types of fibre to various food matrices e. As meat consumption has been epidemiologically related to major degenerative disorders, such as CHD, our group has worked to obtain functional meat products.
Values of total and reduced reduced glutathione, glutathione reductase activity, plasma cholesterol, and total antioxidant capacity differed between rats consuming Nori and those given Dietary fibre is also known as. However, in rats given the restructured pork diet enriched in cholesterol and Sea Spaghetti, SOD expression was similar to that of rats fed the control diet.
Hypolipemic drugs are extensively used to lower and maintain acceptable blood lipid levels. Statins are a class of commonly used, effective hypolipemic drugs. The synergism dietwith statins that increases the efficacy of these drugs may make it possible to Dietary fibre is also known as the dosage, thus avoiding potential adverse effects.
Moreyra et al. Published data indicate that the Mediterranean diet protects against numerous disorders. Consumption of carbohydrates with a low glycemic index in the framework of dietary fibre ensures a diet with a low glycemic load. Consumption of fructose, as an this web page sugar should be avoided.
Thus, a diet of 2, kcal may contain about 25 g of fibre, while that of 2, kcal about 30 g. According to the last World Health Organization workshop on carbohydrates and human nutrition, intact fruits, vegetables, whole grains, nuts and pulses are the best dietary fibre sources, because are rich in cardioprotective components. Due to the positive effects of dietary fibres on the major CVD risk factors known to date, new studies have to be designed to further our understanding of the benefits of dietary fibres in western, Mediterranean, or hypocaloric diets on emerging CVD risk factors, such as Lp apostprandial lipemia, thrombogenesis, blood coagulation factors, inflammation and antioxidant markers.
Moreover, further research is needed on the possible plural interactions between dietary fibre, other dietary compounds and colon microbiota, as fibre compounds are known to interact with dietary macro and micronutrients.
In addition, as there exists hypo and hyporresponders to diet and drug treatment, 21, more information regarding the fibregene interaction is needed in order to personalize and individualize dietotherapy and pharmacotherapy.
Scientific Opinion on Dietary Reference Values for carbohydrates and dietary fibre
Alimentando el conocimiento". Comunidad Europea. Ficha informativa sobre enfermedades Dietary fibre is also known as enfermedades cardiovasculares. American Heart Association. The absolute dietary requirement for glycaemic carbohydrates is not precisely known but will depend on the amount of fat and protein ingested.
Dietary fibre is also known as high frequency of intake of sugar-containing foods can increase the risk of dental caries, Dietary fibre is also known as are insufficient data to set an upper limit for added sugar intake.
Although there is some experimental evidence that a reduction of the dietary glycaemic index and glycaemic load may have favourable effects on some metabolic risk factors such as serum lipids, the evidence for a role in weight maintenance and prevention of diet-related diseases is inconclusive.
Impact of Low Dietary MACs on GUT Epithelium The gut epithelium is a dynamic barrier ensuring the physical separation between the host please click for source the gut microbiota while also enabling their communication Dendritic Cells Short-chain fatty acids elicit numerous effects on the function and hematopoiesis of dendritic cells.
T Cells Short-chain fatty acids have a broad impact on T cell function by directly promoting the differentiation of naïve T cells into Treg 234344Th1, and Th17 45 and indirectly inhibiting Th2 differentiation B Cells Microbiota-accessible carbohydrates appear to be pivotal regulators of Dietary fibre is also known as response both locally in the gut and systemically as mice fed on an MAC-deficient diet have defective homeostatic and pathogen-specific antibody responses Conclusion Food processing has significantly decreased the amount of MAC content in the Western diet, when compared to the contents of the ancestral hominin diet 7.

Facultad de Farmacia. Universidad Complutense. Cardiovascular disease CVD is the leading cause of mortality and morbidity in developed countries. CVD is an inflammatory disease associated with risk factors that include hypercholesterolemia and hypertension.
Furthermore, the evolution of this disease depends on the amount of modified lipoproteins e. Diet is considered the cornerstone for CVD treatment, as it can lower not only atherogenic lipoprotein levels and degree of oxidation, but also blood pressure, thrombogenesis and concentrations of some relevant factors e.
Among different diets, the Mediterranean diet stands out due to their benefits on several health benefits, in particular with regard to CVD. Rich in vegetable foods, this diet contributes both quantitatively and qualitatively to essential fibre compounds cellulose, hemicellulose, gums, mucilages, pectins, oligosaccharides, lignins, etc.
The present paper analyzes the effects of fibre consumption on a cholesterol and lipoprotein levels; b systolic and diastolic blood pressures; and c antioxidant availability and profile.
Some studies and meta-analysis are revised, as the possible mechanisms by which fibre may decrease plasma total cholesterol and LDL-cholesterol and blood Dietary fibre is also known as and to act as antioxidant, as well. The paper also includes data concerning the possible interaction between fibre and some hypolipemic drugs, which may make it possible to attain similar hypolipemic effects with lower dosages, with the consequent decrease in possible side effects.
The review concludes with a summary of nutritional objectives related to the consumption of carbohydrates and fibre supplements. Key words: Fibre. Blood pressure. Es considerada una enfermedad inflamatoria asociada a la presencia de algunos factores de riesgo como hipercolesterolemia e hipertensión.

Cardiovascular disease CVD remains the leading cause of death and disability in developer countries 1 and was predicted by the WHO to Dietary fibre is also known as the major cause of mortality in developing countries by Atherosclerosis, a process characterized by endothelial dysfunction, 3 is associated with several risk factors such article source hypertension, 4 smoking, 5 and hypercholesterolemia.
In its initial phase cholesterol and free radical deposition in macrophages and Dietary fibre is also known as cells in the arterial vessel take place.
This process is related to elevated presence of low-density lipoproteins LDL3,7 Lp a8 and lipoprotein remnants [e. Arterial blood pressure is a key factor in the development of CVD. In turn, among other effects, insulinemia activates the sympathetic Dietary fibre is also known as system and promotes Na retention and smooth muscle cell proliferation Crema de auyama. Controlling the modifiable risk factors can help prevent CVD.
Both the lipoprotein profile and blood pressure, which clearly affect endothelial function and arterial health, can be improved through dietotherapy. Table I summarized central dietary that must be considered in the prophylaxis and treatment of CVD. One of the most article source cited definitions is sic "Dietary fibre is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine with complete or partial fermentation in the large intestine.
Dietary fibre includes polysaccharides, oligosaccharides, lignin and associated plant substances". The distinct composition of the different fibre types explains the plurality of functions ascribes to this Dietary fibre is also known as component, including their water retention capacity, absorption properties bile salt, glucose, and fat absorption binding capacitytendency to form gels, viscosity, fermentability, and ability to modify gut microbiota composition, 17,18,19 these dietary components can affect metabolism and modify certain Dietary fibre is also known as risk factors, improving the prognosis of CVD and reducing the probability of cardiovascular events table II.
In addition, dietary fibres present potential functions that were unknown until recently. The science of nutrigenomics deals with the effects of diet, including those link fibres on the genoma. Moreover, it can be hypothesized that many compounds produced by human microbiota such as enzymes, interleukins and shortchain fatty acids could affect the cellular transcription, translation, and wikihow de peso para bajar Como hacer events of the microbiota and those of neighboring colonocytes Dietary fibre is also known as.
Ample epidemiological evidence exists from follow- up studies performed in large prospective cohorts that examine the hypothesis that higher intake of dietary fibre is inversely related to the risk of CVD and myocardial infarction MI. One study of obliged reference is that of Liu et al. Women were subsequently followed for an average of six years for incidence of nonfatal MI, stroke, percutaneous transluminal coronary angioplasty, coronary artery bypass graft or death due to CVD Dietary fibre is also known as by medical records or death certificates.
A significant inverse association was observed between dietary fibre intake and CVD risk. Comparing the highest quintile of fibre intake median: In this publication 22 it also has shown a comparison of the results between dietary fibre intake and CVD risk in 10 known epidemiological studies.
Interestingly, a stronger association was found on CVD protection for cereal fibre than for vegetable or fruit fibres consumptions fig. Although CVD is a multifactorial disease in which several factors are involved, this review, nonetheless, deals specifically in the effect of dietary fibres in Dietary fibre is also known as review dietary fibre on three CVD-key parameters from which adequate scientific literature is available: a cholesterol metabolism; c blood pressure; and c antioxidant properties.
The effects of dietary fibre intake on cholesterol metabolism have been studied extensively, although the molecular mechanisms involved are not completely known. Time ago, Keys et al.
Martinez de Prado et al. Neutral steroid excretions were higher in pectin fed rabbits.
Babio et al. The authors concluded sic that clinical studies consistently show that the intake of viscous dietary fibre decreases the LDL-cholesterol levels. This, in turn, assures production of more Dietary fibre is also known as acids while decreasing the cholesterol available for inclusion in lipoproteins e. The least fermentable of these compounds include lignin and cellulose, while pectin, gums, resistant starch, mucilage and some oligosaccharides are highly fermentable.
Anaerobic fermentation produces CO 2CH 4H 2and short chain fatty acids butyric, propionic and acetic acids. Dietary fibre is also known as

Propionic acid is thought to have hypocholesterolemic properties in rats and pigs, 40 but this was not substantiated by further studies. Zhang et al. Thus, the mechanism relating fibre fermentability with the decrease in blood cholesterol concentrations in human can not be supported any longer. Nillson et al. Each of the study participants consumed all test meals in random order on link evenings.
At a standardized breakfast following the evening test meals, the postprandial glucose response incremental area under the curve, 0- min was inversely related to plasma butyrate and acetate concentrations. According to the authors, results support the view that cereal products rich in indigestible carbohydrates may Dietary fibre is also known as glucose tolerance through a mechanism involving their colonic fermentation and generation of SCFA, in which butyric acid may play a role.
This mechanism may partially explain the protective effect Dietary fibre is also known as whole grains against type 2 diabetes and CVD. As mentioned above, insulin resistance is associated with atherogenic phenotype B LDL 10,11 fig. Brown et al. In 25 studies involving 1, individuals, an average Dietary fibre is also known as intake of 5 g of oat fibre oat bran led to a net decrease in plasma cholesterol of about 0.
These authors also reported that an average consumption of 9. Furthermore, in 7 studies involving individuals an average daily intake of 4. These authors45 indicated that the effects on plasma lipids of soluble fibre from oat, psyllium, or pectin were not significantly different and triglycerides and HDL cholesterol were not significantly influenced by soluble fibre. In another meta-analysis of 8 controlled trials, Anderson et al. More recently, AbuMweis Dietary fibre is also known as al.
Eleven eligible randomized clinical trials published from to were selected from nine databases.
