Abstract:
The 'gold standard' method for the measurement of total dietary fibre is that of the Association of Official Analytical Chemists (2000; method 985.29). This procedure has been modified to allow measurement of soluble and insoluble dietary fibre, and buffers employed have been improved. However, the recognition of the fact that non-digestible oligosaccharides and resistant starch also behave physiologically as dietaryfibre has necessitated a re-examination of the definition of dietary fibre, and in turn, a re-evaluation of the dietary fibre methods of the Association of Official Analytical Chemists. With this realisation, the American Association of Cereal Chemists appointed a scientific review committee and charged it with the task of reviewing and, if necessary, updating the definition of dietary fibre. It organised various workshops and acceptedcomments from interested parties worldwide through an interactive website. More recently, the (US) Food and Nutrition Board of the Institute of Health, National Academy of Sciences, under the oversight of the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes, assembled a panel to develop a proposed definition(s) of dietary fibre. Various elements of these definitions were in agreement, but not all. What was clear from both reviews is that there is an immediate need to re-evaluate the methods that are used for dietary fibre measurement and to make appropriate changes where required, and to find new methods to fill gaps. In this presentation, the 'state of the art' in measurement of total dietary fibre and dietary fibre components will be described and discussed, together with suggestions for future research.

Abstract:
Dietary fiber (DF) intake is associated with a number of benefits and these effects depend not only on intake as well as its composition. The DF includes polysaccharides such as cellulose, hemicellulose, pectins, gums, oligosaccharides and lignin, and can be divided into soluble and insoluble. The concept of DF was expanded to include resistant starch, inulin and fructo-oligosaccharides. The determination of DF costly and time depends on methods that have been modified for this new concept. The AOAC Official methods of determining all components present in a DF, without specific methods for each component. Studies show innovative techniques to ensure a shorter analysis time, less waste generation by the use of reagents and more convenience in the analysis.

Abstract:
Instead of looking at individual nutrients or foods, dietary pattern analysis has emerged as a promising approach to examine the relationship between diet and health outcomes. Despite dietary patterns being compositional (i.e. usually a higher intake of some foods implies that less of other foods are being consumed), compositional data analysis has not yet been applied in this setting. We describe three compositional data analysis approaches (compositional principal component analysis, balances and principal balances) that enable the extraction of dietary patterns by using control subjects from the Spanish multicase-control (MCC-Spain) study. In particular, principal balances overcome the limitations of purely data-driven or investigator-driven methods and present dietary patterns as trade-offs between eating more of some foods and less of others.

Abstract:
The increased use of dietary supplements in today's society has been attributed to the general public's greater awareness of what constitutes a healthy diet. The elemental content (Ca, Cd, Cr, Co, Cu, Fe, Mg, Mn, Mo, Ni, Pb and Zn) of seventy-four dietary supplements (tablets, capsules and powders) was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Different digestion methods (wet open vessel and microwave) were developed for the dissolution of dietary supplements, utilising both concentrated nitric acid and hydrogen peroxide. Both digestion procedures were found to give no significant statistical difference between the experimental results and certified values at a 99% confidence limit (Paired t-test) for all element values in two certified reference materials, namely NIES Rice Flour and IGGE Tea. For both certified reference materials, there was. The elemental content of the dietary supplements ranged from 0.1-200 mg/g for macro essential elements (Ca, Fe and Mg), 1-500 mug/g for trace essential elements (Cr, Co, Cu, Mn. Mo, Ni and Zn) and 0.4-10 mug/g for non-essential elements (Cd and Pb), all on a dry weight basis. Comparison of experimental results with commercial label values for dietary supplements showed: (1) calculated Ca and Mg concentrations were systematically lower than the label values; and (2) the experimental results for the other essential elements were in good agreement. The essential element contribution of base materials was investigated, though the results were inconclusive. Dietary supplements containing fat-soluble vitamins were analysed for retinol acetate, ergocalciferol (D2), cholecalciferol (D3), tocopherol (E), tocopherol acetate and phylloquinone (K1) using a modified simultaneous high performance liquid chromatography (HPLC) method. For each vitamin, a recovery of >90% was obtained with the use of a direct solvent extraction procedure. An in vitro study into the bioavailability of iron and zinc in yeast-based supplements was accomplished. This study provided results suggesting that iron supplements containing vitamin C were more bioavailable than yeast or tablet-based supplements that contained no vitamin C. Zinc bioavailability was observed to be greater in multi-component and yeast-based dietary supplements.

Abstract:
Introduction: Coenzyme Q10 (CoQ10) is a fat-soluble substance (ubiquinone) which has a bright orange color in appearance and is widely distributed (ubiquitous) in animals and many bacteria. CoQ10’s presence is most prevalent in mitochondria and it is involved in aerobic cellular respiration and aides in converting ingested nutrients into a readily accessible form of energy, specifically ATP (adenosine triphosphate). CoQ10 is supplied through our diets and can be found more in dark leafy green vegetables, fish and organ meats. CoQ10 supplementation should be beneficial due to its characteristic antioxidant scavenging of free radicals that our body produces while in the cellular respiration process for generating energy from nutrients. Although CoQ10 has great antioxidant benefit, a challenge remains for supplement manufacturers to deliver a sufficient does of this sparingly soluble molecule. Dietary supplements do not have the significant FDA oversight that exists for legend drugs, resulting in significant variability within and between brands. The main hypothesis of this project is that commercially available CoQ10 supplements don’t deliver a sufficient mass of CoQ10 when compared to the labelled quantity. Methods: To test this hypothesis, the group purchased and tested 14 commercially available CoQ10 supplements with each serving containing 100 mg of active, choosing a variety of drug delivery systems (DDS) and also included one in-house product, which contained 70 mg of active. The DDSs examined consisted of 7 soft shell gelatin (SSG) capsules (the most common type available), 3 hard shell gelatin (HSG) capsules, 3 tablets (tab), 1 powder, and 1 suspension. Each DDS was placed into a 500 mL volumetric flask (VF) into an aqueous of 0.1 N HCl acid and 0.1% Tween 80, using a standard FDA dissolution method. To facilitate drug release, the contents were removed from the HSG capsules; the SSG capsules were perforated; and the tabs were broken/crushed. After this, a magnetic stir bar was placed into each flask and all DDS samples were vigorously stirred for 30-45 minutes, including being inverted every 10 minutes to further facilitate dissolution of CoQ10 from each DDS. Filtered samples were obtained and the samples were analyzed by a reverse-phase High Performance Liquid Chromatography that was previously developed by this research group. Results and Conclusions: Only two of the 15 products evaluated had significant availability (mean > 50%) of CoQ10; one soft gelatin capsule (Product A, dissolved a mean of 68.57%), and the suspension (Product K, dissolved a mean of 56.71%). All of the other products averaged less than 4% dissolution of the labelled amount (range of values 0.19% to 3.64%). The in-house formulated HSG capsule (Product Q) released a mean amount equal to 8.11% of label (more than twice the percentage of the poorly performing commercial products). The consistency of the products was also variable, with product A having a range of 1.7 to 192 mg of CoQ10 released; Product K had a range of 35.8 to 76.1 mg of drug released. The group concluded that there are acceptable products available, but that most have significant performance issues.

Abstract:
It has been proposed that long-term consumption of diets rich in non-digestible carbohydrates (NDCs), such as cereals, fruit and vegetables might protect against several chronic diseases, however, it has been difficult to fully establish their impact on health in epidemiology studies. The wide range properties of the different NDCs may dilution their impact when they are combined in one category for statistical comparisons in correlations or multivariate analysis. Several mechanisms have been suggested to explain the protective effects of NDCs, including increased stool bulk, dilution of carcinogens in the colonic lumen, reduced transit time, lowering pH, and bacterial fermentation to short chain fatty acids (SCFA) in the colon. However, it is very difficult to measure SCFA in humans in vivo with any accuracy, so epidemiological studies on the impact of SCFA are not feasible. Most studies use dietary fibre (DF) or Non-Starch Polysaccharides (NSP) intake to estimate the levels, but not all fibres or NSP are equally fermentable. It has been proposed that long-term consumption of diets rich in non-digestible carbohydrates (NDCs), such as cereals, fruit and vegetables might protect against several chronic diseases, however, it has been difficult to fully establish their impact on health in epidemiology studies.

However, it is very difficult to measure SCFA in humans in vivo with any accuracy, so epidemiological studies on the impact of SCFA are not feasible. Most studies use dietary fibre (DF) or Non-Starch Polysaccharides (NSP) intake to estimate the levels, but not all fibres or NSP are equally fermentable. The first aim of this thesis was the development of the equations used to estimate the amount of FC that reaches the human colon and is fermented fully to SCFA by the colonic bacteria. Therefore, several studies were examined for evidence to determine the different percentages of each type of NDCs that should be included in the final model, based on how much NDCs entered the colon intact and also to what extent they were fermented to SCFA in vivo. Our model equations are FC-DF or NSP$ 1: 100 % Soluble + 10 % insoluble + 100 % NDOs¥ + 5 % TS** FC-DF or NSP 2: 100 % Soluble + 50 % insoluble + 100 % NDOs + 5 % TS FC-DF* or NSP 3: 100 % Soluble + 10 % insoluble + 100 % NDOs + 10 % TS FC-DF or NSP 4: 100 % Soluble + 50 % insoluble + 100 % NDOs + 10 % TS *DF: Dietary fibre; **TS: Total starch; $NSP: non-starch polysaccharide; ¥NDOs: non-digestible oligosaccharide The second study of this thesis aimed to examine all four predicted FC-DF and FC-NSP equations developed, to estimate FC from dietary records against urinary colonic NDCs fermentation biomarkers. The main finding of a cross-sectional comparison of habitual diet with urinary excretion of SCFA products, showed weak but significant correlation between the 24 h urinary excretion of SCFA and acetate with the estimated FC-DF 4 and FC-NSP 4 when considering all of the study participants (n = 122). Similar correlations were observed with the data for valid participants (n = 78). It was also observed that FC-DF and FC-NSP had positive correlations with 24 h urinary acetate and SCFA compared with DF and NSP alone. Hence, it could be hypothesised that using the developed index to estimate FC in the diet form dietary records, might predict SCFA production in the colon in vivo in humans. The next study in this thesis aimed to validate the FC equations developed using in vitro models of small intestinal digestion and human colon fermentation. The main findings in these in vitro studies were that there were several strong agreements between the amounts of SCFA produced after actual in vitro fermentation of single fibre and different mixtures of NDCs, and those predicted by the estimated FC from our developed equation FC-DF 4. These results which demonstrated a strong relationship between SCFA production in vitro from a range of fermentations of single fibres and mixtures of NDCs and that from the predicted FC equation, support the use of the FC equation for estimation of FC from dietary records. Therefore, we can conclude that the newly developed predicted equations have been deemed a valid and practical tool to assess SCFA productions for in vitro fermentation.

Abstract:
This thesis involves an investigation in three areas; first, a study of an enzymatic-gravimetric method for the analysis of dietary fibre; second, a survey of dietary fibre intake in an area of a developing country, and finally, some observations on the functional aspects of gel-forming dietary fibre in the rat. A simple and rapid enzymatic-gravimetric assay for both soluble and insoluble dietary fibre has been critically investigated. Reference samples were also analysed by a more comprehensive, enzymatic gas chromatographic method to allow testing of the relative accuracy of the enzymatic-gravimetric method. The enzymatic-gravimetric method was found to be highly reproducible but gave a slightly higher value for total dietary fibre than the more comprehensive method. This discrepancy is probably due to the presence of small quantities of resistant starch and protein residue which are recovered in the enzymatic-gravimetric method. In the enzymatic-gas chromatographic method, protein residue is not measured, and resistant starch is estimated, but not counted as dietary fibre. The enzymatic-gravimetric method was applied to the analysis of foods commonly consumed in the Padang region of West Sumatra in Indonesia, in order to estimate dietary fibre intake in the region. Daily intakes of usual foods were estimated by use of a 24-hour recall procedure aided by food photographs to assist in the estimation of portion size. Samples of approximately 60 of the most commonly consumed foods were collected and analysed for dietary fibre. These appear to be the first data which report values for dietary fibre in Indonesion foods and they represent a significant improvement upon the existing data on crude fibre content. Knowledge of the amounts of foods usually consumed and their dietary fibre content allowed an estimation of usual intakes of dietary fibre. Fibre intake was found to be lower than in the developing countries of Africa and was comparable to intakes measured in the U.K. This is the first study to show that in this part of South East Asia, a developing country area using polished rice as a staple food, dietary fibre intakes are as low as in Western countries. Low intakes of fibre are believed to be related to the prevalence of a range of diseases and, in this study, preliminary data on the rates of non-infective, chronic diseases were collected from the two main hospitals in West Sumatra. Chronic, non-infectious diseases such as inguinal hernia, appendicitis, haemorrhoids, diabetes mellitus, hypertension and malignant neoplasms of the rectum are relatively frequent in West Sumatra. While no firm conclusions can be drawn from these data, they do show the possibility of a relationship between low intakes of dietary fibre and the prevalence of these diseases, and suggest that further investigation is necessary. Some observations were made of the effect of gel-forming dietary fibre on stomach emptying and intestinal transit rate in the rat. Xanthan gum was added to iso-osmotic solutions to produce increased viscosity and phenol sulphonphthalein (phenol red) was used as a non-absorbable marker. Gavage feeding of solutions with a range of viscosities was used to study the effect of viscosity on the rate of stomach emptying and intestinal transit. Increased viscosity was observed to slow gastro-intestinal transit and this provides one mechanism by which dietary fibre of the gel-forming type ray improve glucose tolerance.

Abstract:
This thesis explores the use of carbon, nitrogen and sulphur stable isotope analysis of modern and archaeological human hair as an indicator of human diets. The thesis is focused around three distinct research projects, two on modern, living humans and one on an archaeological population. The first project focuses on dietary variation among different populations in modern Ethiopia that share the same resource base but follow different economic and subsistence patterns. This research shows that economic and cultural patterns can cause very distinct and significant differences in diet among populations with access to the same resources. The second project uses data from modern Nicaraguan villagers to explore variability in isotopic signatures among demographic groups within one population. The data reveal significant differences among demographic groups, but the absolute differences are quite small, indicating that it is necessary to have a large sample size to determine isotopic differences within a population. The third project is an archaeological case study presenting the first serial isotopic analysis of human hair from the Basketmaker II (BMII) midden at the site of Turkey Pen Ruins on Cedar Mesa, in south-eastern Utah. These data show potential seasonality of diet at the site, with variations in the amount of C₄ protein being contributed to the diet. Together these projects contribute to our understanding of how different scales of dietary variation can be interpreted and approached through isotopic analysis of human hair. The studies also show the applicability of both intra-individual and inter-individual isotopic analysis of human hair to our understanding of modern and ancient diets.

Abstract:
The diets of 75 two year old children, participating in the Virginia Beach WIC Program, were evaluated twice. They were analyzed using a 24 hour dietary recall (WIC 329), and again using a computer program (Nutritionist I) for RDA. Diets were examined for the nutrients calcium, protein, vitamin A, vitamin C, and iron found in the four food groups on the WIC 329. Each food group and corresponding nutrient was identified with varying degrees of success.The protein and calcium assessment were accurate. Under the conditions of this study, several recommendations can be made. The milk group heading could state that one cup of fluid milk provides 310 IU vitamin A. The vitamin A rich foods yield 6000 IU rather than 4000-5000 IU as indicated on the WIC 329. For vitamin C, only 3/4 serving is required to satisfy the RDA rather than the stated full serving. Iron values could be documented on the WIC 329 for the meat, vitamin A, vitamin C, and bread/cereal group. Iron fortified cereals, supplying at least 45% RDA, could be a separate subgroup to reflect the higher iron content. A truncated regression formula was developed to estimate nutritional status. A ceiling of 150% RDA was used to prevent skewing of nutrients. Use of the regression formula instead of the WIC 329 resulted in a 67% improvement of estimating nutritional status.

Morris, Michelle Anne. "Spatial analysis of dietary cost patterns and implications for health." Thesis, University of Leeds, 2013. http://etheses.whiterose.ac.uk/6894/.

Full text
Abstract:
Background: Chronic diseases such as obesity, cardiovascular disease, diabetes and cancer are a large burden on society, for which diet is the leading modifiable risk factor. ‘Diet’ can encompass a variety of aspects of food consumption. Dietary patterns arguably best reflect food as consumed. The determinants of diet are varied and include cost and availability of foods. The aim of this research is to investigate if dietary patterns and diet cost vary spatially and whether this influences health outcomes, specifically obesity and breast cancer. Methods: Using data from the UKWomen’s Cohort Study, data driven dietary patterns were previously determined. Cost of diet was assigned using a food cost database. Spatial measures for Government Office Region, North South, Urban/ Rural and the Output Area Classification were assigned matched to postcode of the women. Weight status is calculated from self reported height and weight. Time to event analysis investigated association between dietary pattern, diet cost and breast cancer incidence at each spatial scale. Results: There is some spatial variation in dietary patterns both between and within regions. A healthy in more expensive per day than a less healthy one: £6.63 compared to £3.29. The overweight/ obese pay more for their food. Urban and Northern areas have significantly higher BMI than Rural and Southern areas respectively. Those in areas Constrained by Circumstance have highest prevalence of overweight and obesity. There is some spatial variation in breast cancer incidence and variation by dietary pattern. In postmenopausal women, positive association exists between weight status and risk of breast cancer incidence. Methods used for estimating small area dietary patterns and health outcomes may be applicable for use in other developed populations. Conclusion: Understanding determinants of dietary patterns remains important for public health and making healthy diets accessible to all is important. However, while expensive dietary patterns reflect a healthier diet, they do not appear to be the mechanism for which obesity prevalence and breast cancer incidence occur. Geodemographic classifications, combined with other spatial measures could aid more effective targeting of public health nutrition policy.

Abstract:
Scientific evidence shows that dietary patterns are associated with the risk of IBD, particularly among unhealthy and Western dietary patterns. However, Western dietary patterns are not exclusive to Western countries, as Jordanians are steadily moving towards a Western lifestyle, which includes an increased consumption of processed foods. This study aims to investigate the association between dietary patterns and the risk factors for IBD cases among Jordanian adults. This case-control study was conducted between November 2018 and December 2019 in the largest three hospitals in Jordan. Three hundred and thirty-five Jordanian adults aged between 18–68 years were enrolled in this study: one hundred and eighty-five IBD patients who were recently diagnosed with IBD (n = 100 for ulcerative colitis (UC) and n = 85 for Crohn’s disease (CD)) and 150 IBD-free controls. Participants were matched based on age and marital status. In addition, dietary data was collected from all participants using a validated food frequency questionnaire. Factor analysis and principal component analysis were used to determine the dietary patterns. Odds ratios (OR) and their 95% confidence interval (CI) were calculated using a multinomial logistic regression model. Two dietary patterns were identified among the study participants: high-vegetable and high-protein dietary patterns. There was a significantly higher risk of IBD with high-protein intake at the third and fourth quartiles in the non-adjusted model as well as the other two adjusted models. In contrast, the high-vegetable dietary pattern shows a significantly protective effect on IBD in the third and fourth quartiles in all the models. Thus, a high-vegetable dietary pattern may be protective against the risk of IBD, while a high-protein dietary pattern is associated with an increased risk of IBD among a group of the Jordanian population.

Abstract:
Review question / Objective: To systematically evaluate the efficacy of the intestinal microbiome - bile acid pathway (BAS) in the treatment of T2DM. Condition being studied: Bile acids (BAs), an important component of bile, are also metabolites derived from cholesterol and promote intestinal absorption and transportation of dietary lipids . Studies have shown that bile acid receptor agonists can promote glP-1 secretion and improve glucose metabolism in preclinical mouse models of obesity and insulin resistance , which may become a new therapeutic target for Type 2 diabetes. However, no systematic review and meta-analysis has been found on the treatment of type 2 diabetes by intestinal microbiome - bile acid pathway. Therefore, we conducted a systematic review and meta-analysis to evaluate the safety and effectiveness of intestinal microbiome-bile acid pathway in the treatment of type 2 diabetes.

Molecular Analysis of Cellulosome Organization in Ruminococcus Albus and Fibrobacter Intestinalis for Optimization of Fiber Digestibility in Ruminants. United States Department of Agriculture, March 2004. http://dx.doi.org/10.32747/2004.7586475.bard.

Abstract:
Improving plant cell wall (fiber) degradation remains one of the highest priority research goals for all ruminant enterprises dependent on forages, hay, silage, or other fibrous byproducts as energy sources, because it governs the provision of energy-yielding nutrients to the host animal. Although the predominant species of microbes responsible for ruminal fiber degradation are culturable, the enzymology and genetics underpinning the process are poorly defined. In that context, there were two broad objectives for this proposal. The first objective was to identify the key cellulosomal components in Ruminococcus albus and to characterize their structural features as well as regulation of their expression, in response to polysaccharides and (or) P AA/PPA. The second objective was to evaluate the similarities in the structure and architecture of cellulosomal components between R. albus and other ruminal and non-ruminal cellulolytic bacteria. The cooperation among the investigators resulted in the identification of two glycoside hydrolases rate-limiting to cellulose degradation by Ruminococcus albus (Cel48A and CeI9B) and our demonstration that these enzymes possess a novel modular architecture specific to this bacterium (Devillard et al. 2004). We have now shown that the novel X-domains in Cel48A and Cel9B represent a new type of carbohydrate binding module, and the enzymes are not part of a ceiluiosome-like complex (CBM37, Xu et al. 2004). Both Cel48A and Cel9B are conditionally expressed in response to P AA/PPA, explaining why cellulose degradation in this bacterium is affected by the availability of these compounds, but additional studies have shown for the first time that neither PAA nor PPA influence xylan degradation by R. albus (Reveneau et al. 2003). Additionally, the R. albus genome sequencing project, led by the PI. Morrison, has supported our identification of many dockerin containing proteins. However, the identification of gene(s) encoding a scaffoldin has been more elusive, and recombinant proteins encoding candidate cohesin modules are now being used in Israel to verify the existence of dockerin-cohesin interactions and cellulosome production by R. albus. The Israeli partners have also conducted virtually all of the studies specific to the second Objective of the proposal. Comparative blotting studies have been conducted using specific antibodies prepare against purified recombinant cohesins and X-domains, derived from cellulosomal scaffoldins of R. flavefaciens 17, a Clostridium thermocellum mutant-preabsorbed antibody preparation, or against CbpC (fimbrial protein) of R. albus 8. The data also suggest that additional cellulolytic bacteria including Fibrobacter succinogenes S85, F. intestinalis DR7 and Butyrivibrio fibrisolvens Dl may also employ cellulosomal modules similar to those of R. flavefaciens 17. Collectively, our work during the grant period has shown that R. albus and other ruminal bacteria employ several novel mechanisms for their adhesion to plant surfaces, and produce both cellulosomal and non-cellulosomal forms of glycoside hydrolases underpinning plant fiber degradation. These improvements in our mechanistic understanding of bacterial adhesion and enzyme regulation now offers the potential to: i) optimize ruminal and hindgut conditions by dietary additives to maximize fiber degradation (e.g. by the addition of select enzymes or PAA/PPA); ii) identify plant-borne influences on adhesion and fiber-degradation, which might be overcome (or improved) by conventional breeding or transgenic plant technologies and; iii) engineer or select microbes with improved adhesion capabilities, cellulosome assembly and fiber degradation. The potential benefits associated with this research proposal are likely to be realized in the medium term (5-10 years).
