[Ab] Resumo:The present study was aimed at enhancing phytase (Phy-Ck) production from Citrobacter koseri PM-7 using response surface methodology (RSM) and improving the bioaccessibility of minerals (Fe and Zn) and protein digestibility in high-phytate food using Phy-Ck. A five-variable and three-level central composite design of RSM using wheat bran (6.681%, w/v), inoculum level (2.5%, v/v), and triton X-100 (0.2%, v/v) resulted in up to 5.57-fold (1.047 U/ml) improvement in Phy-Ck yield from C. koseri PM-7 when compared with fermentation media I and II. The model was successfully validated in the design space by taking a random set of variable combinations. Treatment of high-phytate food with partially purified Phy-Ck showed improvement in mineral bioaccessibility maximally for defatted sesame flour (DSF) (Fe 45.5%; Zn 50.7%) followed by wheat flour (WF) (Fe 13.5%; Zn 14.4%), green gram flour (GGF) (Fe 0.7%; Zn 3.8%) and defatted groundnut flour (DGF) (Zn 5.6%). The in vitro protein digestibility (IVPD) of WF increased from 48.83 to 65.04%, GGF from 45.04 to 57.12%, and DSF from 47.34 to 55.7% after Phy-Ck treatment.

[Ti] Título:Short-chain fatty acids regulate systemic bone mass and protect from pathological bone loss.

[Ab] Resumo:Microbial metabolites are known to modulate immune responses of the host. The main metabolites derived from microbial fermentation of dietary fibers in the intestine, short-chain fatty acids (SCFA), affect local and systemic immune functions. Here we show that SCFA are regulators of osteoclast metabolism and bone mass in vivo. Treatment of mice with SCFA as well as feeding with a high-fiber diet significantly increases bone mass and prevents postmenopausal and inflammation-induced bone loss. The protective effects of SCFA on bone mass are associated with inhibition of osteoclast differentiation and bone resorption in vitro and in vivo, while bone formation is not affected. Mechanistically, propionate (C3) and butyrate (C4) induce metabolic reprogramming of osteoclasts resulting in enhanced glycolysis at the expense of oxidative phosphorylation, thereby downregulating essential osteoclast genes such as TRAF6 and NFATc1. In summary, these data identify SCFA as potent regulators of osteoclast metabolism and bone homeostasis.

[Ab] Resumo:Byproducts of food processing can be utilized for the production of high-value-added enzyme cocktails. In this study, we utilized integrated functional omics technology to analyze composition and functional characteristics of extracellular enzymes produced by Aspergillus niger grown on food processing byproducts. The results showed that oligosaccharides constituted by arabinose, xylose, and glucose in wheat bran were able to efficiently induce the production of extracellular enzymes of A. niger. Compared with other substrates, wheat bran was more effective at inducing the secretion of ß-glucosidases from GH1 and GH3 families, as well as >50% of proteases from A1-family aspartic proteases. Compared with proteins induced by single wheat bran or soybean dregs, the protein yield induced by their mixture was doubled, and the time required to reach peak enzyme activity was shortened by 25%. This study provided a technical platform for the complex formulation of various substrates and functional analysis of extracellular enzymes.

[Ab] Resumo:The aim of the study was to assess dietary intake in patients with erosive (ERD) and non-erosive reflux disease (NERD). One hundred and sixty seven patients (103 women and 64 men, mean age 47±13,6 years) were divided according to symptoms and endoscopic findings into three groups: 88 patients with NERD, 38 patients with ERD and 41 healthy controls. Symptoms were scored by validated GERDQ questionnaire, dietary intake was assessed by validated food questionnaire and 24-h pH/impedance monitoring was used for confirmation of pathological reflux. All groups were homogenous by age and sex, both NERD and ERD patients demonstrated higher BMI (28.1±6.5 vs 28.4±6.1 kg/m2) in compare to the patients from control group (24.3±2.8 kg/m2). Average daily calorie intake was higher in patients with NERD and ERD (2579±854 vs 2467±710 kcal/day) in compare to the control group (2093±696 kcal/day) due to increased consumption of fat (121±52 vs 112±52 g/day) and carbohydrates (244±88 vs 216±64 g/day) consequently. Consumption of dietary fiber was low in all groups in compare to recommended daily allowance, but even lower in NERD and ERD patients in compare to control (6.0±3.8 g/day vs 5.2±4.8 g/day vs 9.45±5.6 g/day). There was direct correlation between gastroesophageal reflux disease (GERD) and average energy consumption (R=0.23, p<0.05) and daily total fat consumption (R=0.21, p<0.05), but inverse correlation with consumption of dietary fiber (R=-0.23, p<0.05). Consumption of alcohol was higher in NERD patients in compare with ERD patients and control group (1.2±4.9 vs 0.2±2.6 vs 0±0.87 g/day), but generally it was low. Total daily number of refluxes as well as number of acid refluxes were highly correlated with daily consumption of energy (R=0.35, p<0.05; R=0.35, p<0.05), fat (R=0.33, p<0.05; R=0.32, p<0.05) and protein (R=0.3, p<0.05; R=0.25, p<0.05), however inverse correlation was found between total number of refluxes and consumption of fibers (R=-0.22, p<0.05). There was no correlation between consumption of carbohydrates or alcohol and total number of refluxes or acid refluxes. In conclusion, GERD is associated with higher BMI, increased consumption of calories and fat and low consumption of dietary fiber. Total number of refluxes is related to consumption of fat and fibers. No association with consumption of carbohydrates or alcohol was found. These findings need to be taken in account for prescription of diet to GERD patients.

[Ab] Resumo:Irritable bowel syndrome (IBS) is highly prevalent functional gastrointestinal disorder associated with decrease in quality of life and a high social cost. Diet is one of several therapeutic options in IBS treatment; therefore the development and clinical evaluation of innovative functional food for IBS patients is useful. Dry jelly concentrate containing 3 g inulin, 10 mg curcumin and 1.8 mg of pyridoxine was developed and clinically evaluated. Fifty patients fulfilling the Rome III criteria for IBS-C were randomly assigned into two groups: one received standard diet plus two jelly drinks a day for 2 weeks and control group received standard diet. Response to therapy was recorded on a daily basis using Likert scale of abdominal pain, bloating and feeling of incomplete bowel emptying, frequency of bowel movement, Bristol stool scale, and quality of life assessed by IBSQoL questionnaire before and after the treatment. Intake of functional food product (jelly) containing inulin and curcumin is associated with a significant positive effect on the stool parameters (from 0.6±0.24 to 1.15±0.65 t/d in stool frequency, p=0.001, from 2.62±1.23 to 3.99±1.27, index Bristol scale, p=0.001), a reduce of the severity of abdominal pain (from 1.69±0.71 to 1.36±0.44 Likert scale points, p=0.001), bloating (from 2.03±0.89 to 1.55±0.81 points of Likert scale, p=0.02) and a sense of incomplete bowel emptying (from 2.25±0.98 to 1.68±0.92 points of Likert scale, p=0.001), as well as an increase in quality of life (from 64.5±13.5 to 81.2±9.1%, Ñ€=0.05). Patients in control group have improvement in abdominal pain (from 2.16±0.58 to 1.8±0.61 Likert scale points, p=0.05) and bloating (from 2.42±0.83 to 2.16±0.71 Likert scale points, p=0.05) only. During the treatment period no significant adverse events were found. These results indicate that jelly concentrate containing inulin, curcumin and pyridoxine improves abdominal pain score, Bristol scale index and quality of life in patients with IBS-C.

[Ab] Resumo:The content of lactobacilli and enterobacteria in the experiment in rats with varying levels of vitamins and dietary fiber was studied. The study was performed on 48 male weanling Wistar rats randomized into 8 groups, with the creation of vitamin deficiency (30 d.) and its further compensation (5 d.). Vitamin content in the semisynthetic diet in rats of the control group N 1 corresponded to 100% of a daily adequate intake. In the similar composition of the diet of the control group N 2 wheat bran was added in amount of 5% of the weight of the diet. In groups N 3­8 rats received a diet with the reduced amount of vitamin mixture by 5 times (20% of the adequate intake) and the total exclusion of tocopherol, thiamine and riboflavin from the mixture. The wheat bran (5% of diet mass) was added to the diets in Groups N 4, 6, 8. At the stage of compensation of deficiency rats were fed with the diets with increased content of vitamin mixture: Group 5­6 to 80% 7­8 to 200% (100 and 220% of the adequate intake, respectively), and the groups N 3­4 continued to receive deficient diet with or without wheat bran until the end of the experiment. After 35 days rats were anesthetized with ether, decapitated, necropsied and the cecum segments were selected for quantitative microbiological analysis of its contents. It has been shown that the addition of wheat bran to vitamin deficient diet lead to the reduction of the manifestation of physical sign of hypovitaminosis. It also eliminated the differences in the integrated index of growth and development of rats in comparison with the group without vitamin deficiency. It was found that the vitamin deficiency in the diet, regardless of the presence or absence of wheat bran, led to a significant reduction of the number of lactobacilli in the intestinal contents, but almost did not affect the number of normal and opportunistic pathogenic enterobacteria. The compensation of deficiency during 5 days lead to the increased number of lactobacilli, but the physiological levels and levels in control animals it reached only in rats received 220% of the vitamins with the addition of wheat bran. In the lactobacilli population in all rats received different doses of vitamins (including reduced to 20%), regardless of the presence of wheat bran, prevailing culturable representatives were 3 kinds of Lactobacillus spp. ­ acidophilus, fermentum, paracasei. These species showed stable presence in the intestine even in conditions of prolonged vitamin deficiency (35 days). L. acidophilus was the dominated lactoflora representative in all rats, its' content was average 91.7% of all culturable lactobacilli. With less constancy and in lower amounts were detected L. plantarum and representatives of coccal flora (Leuconostoc lactis, Lactococcus lactis).

[Ti] Título:High Levels of Avenanthramides in Oat-Based Diet Further Suppress High Fat Diet-Induced Atherosclerosis in Ldlr Mice.

[Ab] Resumo:Oats, in addition to cholesterol-lowering properties, contain unique antioxidants called avenanthramides (Avns), which inhibit both inflammatory cytokines and adhesion molecules in endothelial cells in culture. This study evaluated the effects of Avns of oats on atherosclerosis in Ldlr mice, one of the most commonly used atherosclerosis mouse models with their similar cholesterol distributions to humans. The Ldlr mice were fed a low fat, high fat, high fat containing regular oat brans with low levels of Avns (HFLA), or high fat containing regular oat brans with high levels of Avns (HFHA) diet. After 16 weeks of intervention, blood cholesterol and extent of aortic lesions were evaluated. We found that both oat-based diets reduced high fat diet-induced atheroma lesions in the aortic valve (p < 0.01). Furthermore, the effects of oat-based diets are more profound in HFHA mice than mice fed HFLA. Total plasma cholesterol levels were similarly reduced in both oat-supplemented mice. We concluded that oat bran diets reduce atheroma lesions and higher levels of Avns further reduce aortic lesions compared to regular oat bran. These preliminary in vivo data indicate that consumption of oats bran, with high Avns, has demonstrable beneficial effects on prevention of cardiovascular disease.

[Ab] Resumo:Dietary factors, such as antioxidant nutrients, contribute significantly to the maintenance of an appropriate balance between antioxidant defense and free radical production in the body. The objective of this study was to examine the relation between oxidative stress as assessed by plasma F -isoprostane (IsoP) concentration, glycemic load (GL), glycemic index (GI), intake of antioxidant nutrients, dietary fiber, and polyunsaturated fatty acids (PUFAs). This study was a cross-sectional secondary analysis of baseline data collected from a random sample of 269 postmenopausal women participating in the Minnesota Green Tea Trial. GL, GI, and dietary variables were calculated from the diet history questionnaire. Subjects filled out surveys about the use of anti-inflammatory drugs and physical activity. Plasma IsoP concentration was assessed by GC-mass spectrometry. IsoP concentrations were compared across quartiles of GL, GI, insoluble fiber, PUFAs, and antioxidant nutrients with the use of linear regression. Antioxidant supplement intake, including zinc, copper, vitamin C and vitamin E, was reported by >60% of the participants. Mean intake of PUFAs was 12.5 g. Mean plasma IsoP concentrations increased from 34 to 36.7 pg/mL in the lowest quartiles of GL and GI, respectively, to 45.2 and 41.6 pg/mL, respectively, in the highest quartiles ( -trend = 0.0014 for GL and -trend = 0.0379 for GI), whereas mean IsoP concentrations decreased from 41.8 pg/mL in the lowest quartile of PUFAs to 34.9 pg/mL in the highest quartile ( -trend = 0.0416). Similarly, mean IsoP concentrations decreased from 44.4 pg/mL in the lowest quartile of insoluble fiber to 36 pg/mL in the highest quartile ( -trend = 0.0243) after adjustment for potential confounders. We concluded that dietary PUFAs and insoluble fiber are inversely associated with oxidative stress whereas GL and GI are positively associated with oxidative stress in postmenopausal women. This trial was registered at clinicaltrials.gov as NCT00917735.

[Ab] Resumo:BACKGROUND: The peel of yellow passion fruit is as an agro-industrial waste of great environmental impact, representing more than 50% of the total weight of the fruit. For this reason, and also considering its importance as a source of functional components such as pectin, this organic waste is increasingly attracting the attention of researchers. The aim of this study was to investigate the physico-chemical composition and physical properties of this material, which may be of interest to the food industry. RESULTS: We obtained two samples of passion fruit peel flour applying different processes: flour without treatment (FWOT) and flour with treatment by maceration (FWT). It was found that the flour samples contain, respectively, 372.4 g kg and 246.7 kg of soluble fiber and, according to the FTIR analysis, this material corresponds to high and low methoxyl pectins, respectively. CONCLUSION: The flour obtained by maceration (FWT) offers greater benefits for industrial use, with 60% fewer tannins and greater thermal stability. In addition, this sample does not reabsorb moisture as easily, although FWOT also shows potential for use in dietary products. Considering the pseudoplastic properties of the flours, the application of both samples could be expanded to many industrial sectors. © 2017 Society of Chemical Industry.

[Ab] Resumo:The aim of this study was to validate the estimated habitual dietary intake from a newly developed web-based FFQ (WebFFQ), for use in an adult population in Norway. In total, ninety-two individuals were recruited. Total energy expenditure (TEE) measured by doubly labelled water was used as the reference method for energy intake (EI) in a subsample of twenty-nine women, and multiple 24-h recalls (24HR) were used as the reference method for the relative validation of macronutrients and food groups in the entire sample. Absolute differences, ratios, crude and deattenuated correlations, cross-classifications, Bland-Altman plot and plots between misreporting of EI (EI-TEE) and the relative misreporting of food groups (WebFFQ-24HR) were used to assess the validity. Results showed that EI on group level was not significantly different from TEE measured by doubly labelled water (0·7 MJ/d), but ranking abilities were poor (r -0·18). The relative validation showed an overestimation for the majority of the variables using absolute intakes, especially for the food groups 'vegetables' and 'fish and shellfish', but an improved agreement between the test and reference tool was observed for energy adjusted intakes. Deattenuated correlation coefficients were between 0·22 and 0·89, and low levels of grossly misclassified individuals (0-3 %) were observed for the majority of the energy adjusted variables for macronutrients and food groups. In conclusion, energy estimates from the WebFFQ should be used with caution, but the estimated absolute intakes on group level and ranking abilities seem acceptable for macronutrients and most food groups.
