maltodextrin and Weight-Gain

Saccharomyces boulardii (SB) is a yeast that acts both as a probiotic and as a polyamine producer. Probiotics prevent the overgrowth of pathogens in the gut while polyamines enhance intestinal maturation. The aim of this randomized study was to investigate the ability of SB to modify the gut microbial ecology and its function.. A total of 87 healthy babies with gestational age 28-32 weeks were studied. They were randomly assigned to receive a preterm formula to which SB or maltodextrins was added for 30 days. Evaluations were made on the following: SB tolerance and weight gain, faecal flora analysis, intestinal D-xylose absorption and faecal lipid excretion.. SB was well tolerated by the infants. There was no difference in weight gain between the two groups. Median log of colony forming units per gram of faeces for Escherichia coli and enterococci was significantly lower in the SB group [E. coli: 2.67 (0.045) vs. 2.75 (0.058), P<0.001; enterococci: 2.14 (0.359) vs. 2.19 (0.138), P<0.05]. On the other hand, the number of bifidobacteria and staphylococci in the stools was significantly higher in the SB group [bifidobacteria: 2.65 (0.083) vs. 2.27 (0.075), P<0.001; staphylococci: 1.23 (0.869) vs. 0.6 (0.281), P<0.001]. D-Xylose and lipid absorption was not improved by SB [median blood D-xylose: 1.5 (0.4) mmol/l vs. 1.35 (0.3) mmol/l, P>0.1; median stool steatocrit: 64% (3.05%) vs. 65% (2.72%) P>0.5].. An SB-supplemented formula is well tolerated by preterm infants, it has a beneficial effect on stool flora bringing it closer to that of breast fed babies but it does not improve D-xylose or lipid gut absorption.

This study examined the effects of ingesting nutritional supplements designed to promote lean tissue accretion on body composition alterations during resistance training. Twenty-eight resistance-trained males blindly supplemented their diets with maltodextrin (M), Gainers Fuel 1000 (GF), or Phosphagain (P). No significant differences were observed in absolute or relative total body water among groups. Energy intake and body weight significantly increased in all groups combined throughout the study with no group or interaction differences observed. Dual energy x-ray absorptiometry-determined body mass significantly increased in each group throughout the study with significantly greater gains observed in the GF and P groups. Lean tissue mass (excluding bone) gain was significantly greater in the P group, while fat mass and percent body fat were significantly increased in the GF group. Results indicate that total body weight significantly increased in each group and that P supplementation resulted in significantly greater gains in lean tissue mass during resistance training.

A double-blind, randomized controlled study was used to compare the efficacy and safety of an oral rehydration solution either with minimally hydrolyzed maltodextrins or the standard recommended glucose. One hundred twenty pediatric patients with acute watery diarrhea (60 in each group) were studied, but only 116 patients were included in the final analysis. After rehydration, outcome variables did not differ significantly at p < 0.05. Mean duration of diarrhea was 52.5 +/- 32.2 h for the control group (median, 50.8 h) and 57.2 +/- hours for the study group (median, 45.3 hours). Comparisons of the mean stool output, weight gain, and ORS intake on the 24th h and from admission to discharge were not statistically significant. Differences in laboratory parameters consisting of mean serum sodium, potassium, total CO2, hematocrit, plasma total solids, urine specific gravity, and random blood sugar were likewise not significant. Differences in stool pH and reducing sugars were statistically significant; however, the observed values were still within normal range. All laboratory values improved upon rehydration. Replacement of glucose with maltodextrins did not offer added advantages in reducing the duration and severity of diarrhea.

Male children (N = 101) 6-35 months of age presenting with acute watery diarrhea for less than 48 h at home before hospitalization were admitted into a randomized, double-blind clinical trial. Fifty-one children were treated with standard oral rehydration solution (ORS) (World Health Organization [WHO] formulation containing citrate) and 50 were treated with an improved ORS formulation (containing, in addition to the standard formula, 20 g maltodextrin instead of glucose, and 4 g glycine and 4 g glycyl-glycine). None were given antibiotics. No i.v. infusions were given. Rotavirus was detected by enzyme-linked immunosorbent assay in stools of 43 children. Clinical characteristics of children in the two treatment groups were comparable. Improved ORS did not produce significant reduction in the volume of diarrhea stools. Children given improved ORS had greater weight gain than that observed in children treated with standard ORS, but the differences were not statistically significant except at the end of the first 24 h. Among children with rotavirus diarrhea, no significant differences were observed between the 23 children who received improved ORS and the 20 who received standard ORS.

One hundred and eight male adults (mean age 33 +/- 1.7 years) presenting with watery diarrhoea of less than 48 hours duration at home prior to hospitalization and with clinically evident (grade II, severe) dehydration were admitted into a randomized double-blind clinical trial; 54 were treated with standard oral rehydration solution (ORS)--WHO formulation containing citrate--and 54 with an improved ORS formulation which contained, in addition to the standard formula, maltodextrin 20 g (instead of glucose), glycine 4 g and glycyl-glycine 4 g. Patients with clinical cholera were given tetracycline 500 mg q.i.d. Vibrio cholerae was detected in 85 patients. The clinical characteristics of patients in the two groups were comparable. The improved ORS did not reduce the volume of diarrhoeic stools in cholera; indeed, patients with cholera who were treated with improved ORS had larger diarrhoea stool volumes. However, those cholera patients given improved ORS showed significantly greater weight gains during the first six-hour period, at the end of the second day, and at discharge. On the other hand, non-cholera patients treated with improved ORS had significantly smaller diarrhoeic stool volumes during the six to 24-hour significantly smaller diarrhoeic stool volumes during the six to 24-hour period (i.e. during the commencement of maintenance rehydration therapy).

We have reported large differences in adiposity (fat mass/body weight) gain between rats fed a low-fat, high-starch diet, leading to their classification into carbohydrate "sensitive" and "resistant" rats. In sensitive animals, fat accumulates in visceral adipose tissues, leading to the suggestion that this form of obesity could be responsible for rapid development of metabolic syndrome.. We investigated whether increased amylase secretion by the pancreas and accelerated starch degradation in the intestine could be responsible for this phenotype.. Thirty-two male Wistar rats (7-wk-old) were fed a purified low-fat (10%), high-carbohydrate diet for 6 wk, in which most of the carbohydrate (64% by energy) was provided as corn starch. Meal tolerance tests of the Starch diet were performed to measure glucose and insulin responses to meal ingestion. Indirect calorimetry combined with use of 13C-labelled dietary starch was used to assess meal-induced changes in whole body and starch-derived glucose oxidation. Real-time polymerase chain reaction was used to assess mRNA expression in pancreas, liver, white and brown adipose tissues, and intestine. Amylase activity was measured in the duodenum, jejunum, and ileum contents. ANOVA and regression analyses were used for statistical comparisons.. "Resistant" and "sensitive" rats were separated according to adiposity gain during the study (1.73% ± 0.20% compared with 4.35% ± 0.36%). Breath recovery of 13CO2 from 13C-labelled dietary starch was higher in "sensitive" rats, indicating a larger increase in whole body glucose oxidation and, conversely, a larger decrease in lipid oxidation. Amylase mRNA expression in pancreas, and amylase activity in jejunum, were also higher in sensitive rats.. Differences in digestion of starch can promote visceral fat accumulation in rats when fed a low-fat, high-starch diet. This mechanism may have important implications in human obesity.

Endurance athletes search for diet regimens that will improve performance and decrease gastrointestinal disturbances during training and events. Although the intestine can adapt to changes in the amount and composition of dietary inputs, the responses to the combination of endurance exercise and diet are poorly understood.. We evaluated small intestinal dimensions and mucosal architecture and calculated the capacities of the entire small intestine to digest maltose and maltodextrin and absorb glucose in response to two different diet types; a western human diet and the Daniel Fast, a vegan style diet, and with moderate intensity endurance training or a no-exercise sedentary lifestyle for a 13 week period (n = 7 per group). The influences of diet and exercise, alone and in combination, were analyzed by analysis of variation.. Rats fed the western diet gained more weight (P < 0.05) due to more fat mass (P < 0.05), with a similar response for the sedentary compared with the exercised rats in each diet group (P < 0.05). The Daniel Fast rats had longer and heavier intestines with deeper crypts with villi that were wider (P < 0.05), but not taller. Despite increased energetic demands, the exercised rats had shorter and lighter intestines with shorter villi (P < 0.05). Yet, the percentage of mucosa did not differ among groups. Total small intestinal activities for maltase and α-glucoamylase, and capacities for glucose absorption were similar regardless of diet or exercise.. These findings indicate the structural responses of the small intestine to a vegan style diet are modified by exercise, but without altering the capacities of the brush border membrane to digest and absorb carbohydrates.

Commercial pigs display an innate attraction for sweet taste compounds. However, the impact of long-term availability to supplementary carbohydrate solutions on their general feeding behavior has not been examined. In this work we assess the effect of 12-days exposure to 16% sucrose and 16% maltodextrin solutions on the feed intake and growth performance of piglets, and on their preference and appetence for sweet or protein solutions. The innate preference of piglets was assessed by an initial choice test between 2% sucrose and 2% animal plasma solutions for a period of three minutes. Piglets showed higher intake and preference for 2% sucrose than for 2% animal plasma. In Experiment 1, piglets were then free-offered a 16% sucrose solution as a supplement to the diet, showing a higher intake of it than water and a reduction in feed intake and weight gain. A similar situation occurred during the last days of free-exposure to a 16% maltodextrin solution in Experiment 2. The choice test between 2% sucrose and 2% animal plasma solution was repeated after the exposure to the concentrated solutions. In both experiments, a reduction in the initial preference for 2% sucrose was observed. Similarly, piglets that had previous access to the 16% sucrose and 16% maltodextrin solutions showed a decrease in the appetence for 2% sucrose in comparison with that for 2% animal plasma, as measured by a one-pan test at the end of the experiments. It is concluded that long-term exposure to concentrated sucrose and maltodextrin solutions reduces feed intake and growth in weanling piglets, and also reverses their innate preference and appetence for dilute sweet over protein solutions.

Resistant glucan (RG) and hydrogenated resistant glucan (HRG) are newly developed non-digestible carbohydrate materials that decrease lifestyle-related diseases. The bioavailability of RG and HRG was investigated by in vitro experiments using human and rat small intestinal enzymes and by in vivo experiments using rats in the present study. Oligosaccharides, which are minor components of RG and HRG, were hydrolysed slightly by small intestinal enzymes of humans and rats, and the hydrolysing activity was slightly higher in rats than in humans. The amount of glucose released from HRG was greater than that from RG. However, the high-molecular-weight carbohydrates of the main components were hardly hydrolysed. Furthermore, neither RG nor HRG inhibited disaccharidase activity. When rats were raised on a diet containing 5 % of RG, HRG, resistant maltodextrin or fructo-oligosaccharide (FOS) for 4 weeks, all rats developed loose stools and did not recover during the experiment, except for the FOS group. Body weight gain was normal in all groups and was not significantly different compared with the control group. Caecal tissue and content weights were significantly increased by feeding RG or HRG, although other organ and tissue weights were not significantly different among the groups. In conclusion, RG and HRG consist of small amounts of glucose and digestible and non-digestible oligosaccharides, and large amounts of glucose polymers, which were hardly hydrolysed by α-amylase and small intestinal enzymes. RG and HRG, which were developed newly as dietary fibre materials, had no harmful effects on the growth and development of rats.

The aim of the present study was to determine the potential long-term metabolic effects of early nutritional programming on carbohydrate utilisation in adult zebrafish (Danio rerio). High-carbohydrate diets were fed to fish during four ontogenetic stages: from the first-feeding stage to the end of the yolk-sac larval stage; from the first-feeding stage to 2 d after yolk-sac exhaustion; after yolk-sac exhaustion for 3 or 5 d. The carbohydrate stimuli significantly increased the body weight of the first-feeding groups in the short term. The expression of genes was differentially regulated by the early dietary intervention. The high-carbohydrate diets resulted in decreased plasma glucose levels in the adult fish. The mRNA levels and enzyme activities of glucokinase, pyruvate kinase, α-amylase and sodium-dependent glucose co-transporter 1 were up-regulated in the first-feeding groups. There was no significant change in the mRNA levels of glucose-6-phosphatase (G6Pase) in any experimental group, and the activity of G6Pase enzyme in the FF-5 (first feeding to 2 d after yolk-sac exhaustion) group was significantly different from that of the other groups. The expression of phosphoenolpyruvate carboxykinase gene in all the groups was significantly decreased. In the examined early programming range, growth performance was not affected. Taken together, data reported herein indicate that the period ranging from the polyculture to the external feeding stage is an important window for potential modification of the long-term physiological functions. In conclusion, the present study demonstrates that it is possible to permanently modify carbohydrate digestion, transport and metabolism of adult zebrafish through early nutritional programming.

In the context of the well-documented metabolic and behavioural effects of supplementing rats' diets with access to a sucrose solution, the aim of this study was to compare the impact of 10% sucrose with that of an isoenergetic (10.4%) solution of hydrolysed starch, maltodextrin. This polysaccharide is metabolised at least as rapidly as sucrose and is also very palatable to rats, but does not contain fructose. Each of three experiments contained three groups: one given a sucrose solution, one given a maltodextrin solution and a control group maintained on standard chow and water alone. In Experiment 1 the sucrose and maltodextrin groups were given their supplementary drinks for 2 h each day, while in Experiments 2 and 3 these groups had 24-h access to their supplements. Ad libitum access to maltodextrin produced at least as rapid weight gain as sucrose and in Experiment 2 retroperitoneal fat mass was greater in the two carbohydrate groups than in the control group. Moreover, in Experiment 3, impaired performance on a location recognition task was also found in both carbohydrate groups after only 17 days on the diets. These results indicate that the harmful effects of excess sucrose consumption can also be produced by another rapidly absorbed carbohydrate that does not contain fructose.

Omnivorous mammals are able to adaptively modulate rates of intestinal nutrient transport to match changes in diet. Because adaptive responses during suckling, when dietary composition is relatively constant, have not been adequately determined, we measured in vitro sugar and amino acid uptake [nmol/(mg tissue.min)] in suckling pigs fed milk replacers with either lactose (LAC) or a 60:40 mixture of maltodextrin and sucrose (MDS). The MDS-fed pigs initially grew slower, but had intestinal dimensions similar to those of LAC-fed siblings when normalized to body weight. Carrier-mediated uptake for three monosaccharides (glucose, galactose, fructose) did not differ between LAC- and MDS-fed pigs at 5, 10, 15 and 20 d of age. Interdiet differences in rates of leucine and proline uptake, despite identical types and concentration of protein in both milk replacers, are indicative of non-specific responses to diet during suckling. Uptake capacities (grams of monosaccharide absorbed per 24 h) never exceeded estimates of monosaccharide intake by more than fourfold and were less than aldohexose intake during early suckling. Our results indicate 1) age-related changes in rates of nutrient uptake are genetically programmed and little influenced by diet; 2) any responses to diet are nonspecific and likely involve a shift in the timing of the genetic program; and 3) at birth and throughout suckling, pigs are capable of absorbing limited quantities of alternative nutrients.
