The bulking index (i.e. the increase in faecal fresh weight in gram per gram indigestible carbohydrate ingested) with oligofructose and inulin is similar to that produced with other easily fermented fibres such as pectins and gums. Most studies in man have been performed at a level of 15 g/d and more investigations on lower intakes are needed to appoint the least intake for an effect. Concerning short-chain fatty acids (SCFA) most studies have been using oligofructose and points at an increased butyric acid formation in the caecum of rats. In one study on rats with inulin high caecal proportions of propionic acid were obtained. As inulin has a higher molecular weight than oligofructose it might be speculated if this could be a reason to the different SCFA-profile formed. No effects on faecal concentrations of SCFA in humans have been revealed with inulin and oligofructose, which neither is expected as most of the SCFA formed during the fermentation already has been absorbed or utilized by the colonic mucosa.

Introduction: The intestinal microbiota has been the subject of research due to its association in physiological and pathological conditions. The production of short chain fatty acids obtained by fermentation of the intestinal microbiota has shown important effects on the gastrointestinal tract, adipose tissue, immune system and nervous system. Objective: This literature review aims to present different nutritional strategies with the potential to modulate the intestinal microbiota by increasing the production of short chain fatty acids. Methods: The research was considered a review work, through a bibliographic survey carried out from the collection of articles in English, published in the PubMed database, in the period from 2013 to 2020. The articles were selected from the descriptors: gut microbiota, soluble fiber, resistent starch, pectin, dietary fiber, short chain fatty acids (SCFA) with the combinations of the Boolean operators “and” and “or”. Studies considered as gray literature were excluded, as well as studies in which the titles were not related to the theme of the proposed research. Results: There are many benefits to consuming foods that may favor the increase of short chain fatty acids. This increase in the gastrointestinal tract is of fundamental importance for the maintenance of intestinal microbiota and prevention of diseases. Some nutritional strategies can be used in clinical therapy, such as increased consumption of fruits, vegetables and whole grains that are plant foods and important sources of fiber. The type of food must be observed, since each one can contain fibers of diverse types. Soluble fiber is the basis for the metabolization of short chain fatty acids and is found in various foods that can be inserted into the food plan, such as: bananas, apples, oats, barley, cooked and cooled potatoes, partially ground seeds, corn, morning cereal, agave, artichoke, asparagus, chicory root, garlic, onion, leeks and wheat. Conclusion: Scientific evidence of the relationship between nutrition, intestinal microbiota and short-chain fatty acid production demonstrates the importance of implementing simple nutritional strategies by health professionals, which can contribute to the modulation of the intestinal microbiota and the development of new perspectives in the development of therapies for prevention and treatment of diseases.

Abstract Objectives Okara is a fiber-rich food processing by-product. However, it is underutilized as food due to its rapid putrefaction and poor sensorial properties. Valorization via fermentation (biovalorization) can alleviate its undesirable qualities while augmenting its soluble fiber content. The increase in soluble fiber may improve postprandial glycemic and insulinemic responses, potentially via generation of short-chain fatty acids (SCFAs) from colonic bacteria fermentation. This study aimed to assess the effect of consuming okara and biovalorized okara-containing biscuits on postprandial glucose, insulin and SCFAs responses in older Singaporeans. Methods Fifteen healthy middle-aged and older Singaporeans participated in a randomized controlled crossover trial. Subjects underwent a 4-hour mixed meal tolerance test with 100 g ingestion of 3 types of biscuits – control (C, no okara), biovalorised okara (RO) and autoclaved okara (AOK). RO and AOK biscuits were produced by 20% substitution of wheat flour with okara powder that was fermented with Rhizopus oligosporus (7% w/w) or autoclaved. The 4-hour incremental area under the curve (iAUC) of glucose, insulin and SCFAs (acetate, propionate and butyrate) were assessed. β-cell function was evaluated based on glucose stimulated insulin secretion, using a ratio of 4-hour AUC of insulin to glucose. Estimated insulin sensitivity (ISI) and metabolic clearance rate (MCR) were assessed with Stumvoll Index. Results Although no difference in glucose response was noted, RO showed significantly lower insulin iAUC (RO: 8931 ± 1058 mU/L × min, mean ± SE; C: 10271 ± 866 mU/L × min, p = 0.021) and improved β-cell function (p = 0.028) compared to C. AOK yielded significantly greater ISI and MCR compared to C (pISI = 0.016, pMCR = 0.009) while RO showed no difference against AOK or C. Significantly higher acetate and total SCFAs iAUC were evident for both RO and AOK relative to C (C vs RO: pacetate = 0.012, ptotal SCFA = 0.001; C vs AOK: pacetate = 0.015, ptotal SCFA = 0.001). AOK also had significantly greater propionate and butyrate iAUC compared to C (C vs AOK: pacetate = 0.002, pbutyrate = 0.001). Conclusions Consumption of okara and biovalorized okara-containing biscuits offers the benefit of attenuating postprandial insulinemic response possibly via SCFAs modulation.

Mucosal membranes act as a network that provides a connection between the gut and vital organs, like the lungs or the brain, but presumably the entire body. Short-chain fatty acids are formed in the colon through the fermentation of soluble fiber, and researchers are interested in finding out more about their role as signaling compounds. More research is needed to decisively say that one diet is better for the microbiome over another.
