“…Other studies with RS have shown a change in SCFA and fecal pH. However, these studies administered doses ranging from 30 to 50 g/day [20][21][22] . A larger sample size and more specific fermentation metabolite analysis may be required to see a relationship between pH and SCFA concentration.…”

Background: Average dietary fiber intake in the United States is roughly half of the recommended amount. As new dietary fiber products are introduced to increase fiber intake, it is critical to evaluate the physiological effects of such fibers. Aims: This study examined the effect of 4 fibers derived from maize or tapioca on fecal chemistry, gastrointestinal (GI) symptoms and serum markers of chronic disease. Methods: Twenty healthy subjects completed the single-blind crossover study in which 12 g/day of fiber (pullulan, Promitor™ Resistant Starch, soluble fiber dextrin or Promitor Soluble Corn Fiber) or placebo (maltodextrin) were consumed for 14 days followed by a 21-day washout. GI symptom surveys were completed (days 3 and 14), stools were collected (days 11–14), diet was recorded (days 12–14) and fasting blood samples were obtained (day 15). Results: The 4 test fibers were well tolerated, with mild to moderate GI symptoms. Total short-chain fatty acid (SCFA) concentrations did not differ among the treatments. Fecal pH and individual SCFAs were affected by some treatments. Stool weight and serum markers of chronic disease did not change with these treatments. Conclusion: Increasing fiber intake by 12 g/day was well tolerated and may have a positive impact on colon health due to fermentation.

“…RS is well tolerated in humans, even in high doses (45-60 g/day) [15,20,22,23] . RS doses above 60 g/day produced greater flatulence, abdominal distension and abdominal cramping compared to control treatments in previous reports [13,24,25] .…”

“…Because each individual harbors a unique microbial community consisting of complex interactions between bacteria, pooling does pose a risk of creating interactions between bacteria that would not occur under physiological conditions. Nevertheless, pooling has been recommended [23] and utilized by a number of researchers (e.g., [19, 24 -26]) to create a general microbiota that is free of anomalous results that may arise from the microbiota from a single individual [27]. Within 2 h of collection, during which time they were kept on ice, feces were pooled and homogenized with anaerobic media (1:15 w/v) [28], and filtered through four layers of cheesecloth under continuous carbon dioxide flushing.…”

Previous research has revealed that waxy corn starch which has been entrapped in a matrix of electrostatically cross-linked alginate, shows a slow digestion rate such that much of the starch may reach the colon; thus making this a new type of resistant starch. The purpose of this research was to test the fermentative properties of starch-entrapped microspheres using a batch fecal fermentation method. Fermentation of starch-entrapped microspheres showed significantly lower rates of gas production compared to waxy corn starch, and showed significant increases in total SCFAs during the latter stages of fermentation (24-48 h), whereas waxy corn starch did not. Cooking the starch-entrapped microspheres increased the amount of SCFAs and the molar fraction of butyrate produced during fermentation. Bacterial fingerprinting revealed that uncooked starch-entrapped microspheres have a unique effect on the microbiota that is different from waxy corn starch alone, but cooking causes a shift toward a pattern more closely resembling that of the starch. Starch-entrapped microspheres may deliver slowly fermentable carbohydrate to the colon, with the ability to influence the microbiota. Further human studies are required to determine whether these characteristics occur in vivo.

“…26 HAS was fermented rapidly and completely during in vitro incubation with faecal slurry of both test groups, and fermentability of HAS was comparable with that of digestible starch. HAS digestibility would be affected by conditions of the experiment such as the subject of animal, starch dose and intake period.…”
