RESUMO

OBJECTIVE: To assess the Na content and price of bread available in bakeries in the city of Maputo in 2018 and describe trends since 2012. DESIGN: Cross-sectional evaluation of bread sold in twenty bakeries in the city of Maputo. Three loaves of white and three loaves of brown bread were collected from each bakery when available, and Na contents were quantified by flame photometry. To assess trends, samples of white bread collected in 2012 and analysed using the same methodology were compared with samples of white bread collected in 2018 from the same bakeries. SETTING: City of Maputo, capital of Mozambique. RESULTS: In 2018, the mean (range) Na content in mg/100 g of white and brown breads were 419·1 (325·4-538·8) and 389·8 (248·0-609·0), respectively. Non-compliance with Na targets in bread according to the South African regulation (<380 mg/100 g) was observed in 70 % of white and 43 % of brown bread samples. A total of twelve bakeries had samples evaluated in both 2012 and 2018; among these, the mean Na content in white bread decreased by just over 10 % - the mean difference (95 % CI) was 46·6 mg/100 g (1·7, 91·5); and there was a significant increase of 3·7-5·4 meticais in the mean price per 100 g of white bread. CONCLUSIONS: The Na content of bread available in bakeries in the city of Maputo decreased in recent years despite the absence of a specific regulation in Mozambique.

RESUMO

OBJECTIVE: To characterize the sociodemographic profile associated with the probabilities of consumption of nonessential energy-dense foods (ANBADE), taxed since 2014. MATERIALS AND METHODS: We used the National Health and Nutrition Survey (Ensanut) 2012. ANBADE group was identified and probit models were estimated for the probabilities of consumption (PC) and of belonging to the high quintile of consumption after adjusting for total energy intake (PAC), as a function of sociodemographic characteristics. RESULTS: School-aged children have a PAC 10.7 percentage points (pp) higher vs. preschool-aged. Belonging to households with the highest expenditures or education of the head of the household are associated with a PC 3.3 or 3.2 pp higher vs. households with lower expenditures or education of the head, respectively. Living in metropolitan areas is associated with a PAC 5.2 pp higher vs. rural areas. CONCLUSIONS: The study identified the sociodemographic conditions associated with the largest PC or PAC of ANBADE, which may be considered in the design and evaluation of food policy.


OBJETIVO: Caracterizar el perfil sociodemográfico que se asocia con las probabilidades de consumo de alimentos no básicos de alta densidad energética (ANBADE), gravados desde 2014. MATERIAL Y MÉTODOS: Se utilizó la Encuesta Nacional de Salud y Nutrición (Ensanut) 2012. Se identificó el grupo de ANBADE y se estimaron modelos probit sobre las probabilidades de consumo (PC) y de alto consumo después de ajustar por energía total (PAC), en función de características sociodemográficas. RESULTADOS: Los escolares tienen 10.7 puntos porcentuales (pp) más PAC frente a los preescolares. Pertenecer a hogares con el mayor gasto o escolaridad del jefe se asocia con una PC 3.3 y 3.2 pp mayor en comparación con los hogares de menor gasto o escolaridad del jefe, respectivamente. Vivir en localidades metropolitanas se asocia con una PAC 5.2 pp mayor frente a localidades rurales. CONCLUSIONES: El estudio identificó las condiciones sociodemográficas que se asocian con las mayores PC o PAC de ANBADE, que podrán considerarse en el diseño y evaluación de la política alimentaria.

RESUMO

BACKGROUND: Coeliac disease affects approximately 1% of the population and is increasingly diagnosed in the United Kingdom. A nationwide consultation in England has recommend that state-funded provisions for gluten-free (GF) food should be restricted to bread and mixes but not banned, yet financial strain has prompted regions of England to begin partially or fully ceasing access to these provisions. The impact of these policy changes on different stakeholders remains unclear. METHODS: Prescription data were collected for general practice services across England (n = 7176) to explore changes in National Health Service (NHS) expenditure on GF foods over time (2012-2017). The effects of sex, age, deprivation and rurality on GF product expenditure were estimated using a multi-level gamma regression model. Spending rate within NHS regions that had introduced a 'complete ban' or a 'complete ban with age-related exceptions' was compared to spending in the same time periods amongst NHS regions which continued to fund prescriptions for GF products. RESULTS: Annual expenditure on GF products in 2012 (before bans were introduced in any area) was £25.1 million. Higher levels of GF product expenditure were found in general practices in areas with lower levels of deprivation, higher levels of rurality and higher proportions of patients aged under 18 and over 75. Expenditure on GF food within localities that introduced a 'complete ban' or a 'complete ban with age-related exceptions' were reduced by approximately 80% within the 3 months following policy changes. If all regions had introduced a 'complete ban' policy in 2014, the NHS in England would have made an annual cost-saving of £21.1 million (equivalent to 0.24% of the total primary care medicines expenditure), assuming no negative sequelae. CONCLUSIONS: The introduction of more restrictive GF prescribing policies has been associated with 'quick wins' for NHS regions under extreme financial pressure. However, these initial savings will be largely negated if GF product policies revert to recently published national recommendations. Better evidence of the long-term impact of restricting GF prescribing on patient health, expenses and use of NHS services is needed to inform policy.

RESUMO

We investigated the price difference between gluten-free (GF) and gluten-containing (GC) foods available in rural Maritime stores. GF foods and comparable GC items were sampled through random visits to 21 grocery stores in nonurban areas of Nova Scotia, New Brunswick, and Prince Edward Island, Canada. Wilcoxon rank tests were conducted on price per 100 g of product, and on the price relative to iron content; 2226 GF foods (27.2% staple items, defined as breads, cereals, flours, and pastas) and 1625 GC foods were sampled, with an average ± SD of 66 ± 2.7 GF items per store in rural areas and 331 ± 12 in towns. The median price of GF items ($1.76/100 g) was more expensive than GC counterparts ($1.05/100 g) and iron density was approximately 50% less. GF staple foods were priced 5% higher in rural stores than in town stores. Although the variety of GF products available to consumers has improved, higher cost and lower nutrient density remain issues in nonurban Maritime regions. Dietitians working in nonurban areas should consider the relative high price, difficult access, and low iron density of key GF items, and work together with clients to find alternatives and enhance their food literacy.

RESUMO

Unhealthy food in advertising has been suggested as a mediator for the increase in diet-related illness. This study quantitatively investigates changes in food advertising between 1995 and 2014 in terms of food categories promoted, macronutrient content, and percentage of foods classified as heathy or unhealthy from a sample of 7,199 ads from three Swedish food magazines. With the exception of increased alcoholic beverage and decreased carbohydrate-rich-food promotion, no monotonic trends of increasingly unhealthy food advertisement are found. From these findings, it is argued that food magazine advertising is not a mediator of the adverse dietary trend.

RESUMO

Extending the shelf-life of bakery products has been an important requirement resulting from the mechanization of this industry and the need to increase the distance for the distribution of final products, caused by the increase in production and consumer demand. Technologies based on the interruption of the breadmaking process represent an alternative to overcome product staling and microbiological deterioration. The production of par-baked breads is one of these technologies. It consists of baking the bread in two stages, and due to the possibility of retarding the second stage, it can be said that the bread can always be offered fresh to the consumer. The technology inserts logistics as part of the production process and creates the "hot point" concept, these being the locations where the bread is finalized, such as in the consumers' homes or sales locations. In this work, a review of the papers published on this subject was carried out, and aspects related to both the formulation and the process were considered. This technology still faces a few challenges, such as solving bread quality problems that appear due to process modifications, and these will also be considered. The market for these breads has grown rapidly and the bakery industry searches innovations related to par-baked bread technology.

RESUMO

OBJECTIVE: To examine the associations between financial, physical and transport conditions that may restrict food access (which we define as food security indicators) and the purchase of fast foods and nutritious staples such as bread and milk. DESIGN: Multilevel logistic and multinomial regression analysis of cross-sectional survey data to assess associations between the three indicators of food insecurity and household food shopping adjusted for sociodemographic and socio-economic variables. SETTING: Random selection of households (n 3995) from fifty Census Collector Districts in Melbourne, Australia, in 2003. SUBJECTS: The main food shoppers in each household (n 2564). RESULTS: After adjustment for confounders, analysis showed that a greater likelihood of purchasing chain-brand fast food on a weekly basis compared with never was associated with running out of money to buy food (OR = 1·59; 95 % CI 1·08, 2·34) and reporting difficulties lifting groceries (OR = 1·77; 95 % CI 1·23, 2·54). Respondents without regular access to a car to do food shopping were less likely to purchase bread types considered more nutritious than white bread (OR = 0·75; 95 % CI 0·59, 0·95) and milk types considered more nutritious than full-cream milk (OR = 0·62; 95 % CI 0·47, 0·81). The food insecurity indicators were not associated with the purchasing of fruits, vegetables or non-chain fast food. CONCLUSIONS: Householders experiencing financial and physical barriers were more likely to frequently purchase chain fast foods while limited access to a car resulted in a lower likelihood that the nutritious options were purchased for two core food items (bread and milk). Policies and interventions that improve financial access to food and lessen the effect of physical limitations to carrying groceries may reduce the purchasing of fast foods. Further research is required on food sourcing and dietary quality among those with food access restrictions.

RESUMO

BACKGROUND: Tomato pomace (TP), obtained as a residue of tomato processing, was used to enrich rye bread (RB). The sensory profile of this functional bread (RB+TP) was characterised, and its fat absorption and lipid metabolism properties in high-fat-fed rats were studied. RESULTS: Intake of the HF diet containing RB, RB+TP, or TP alone increased faecal energy and fat excretion, but did not affect animal growth or visceral fat weight. Both RB and RB+TP diminished the negative impact of the HF diet, lowering the atherogenic index of plasma (AIP) and the total liver lipid contents by 31.6% and 24%, respectively. The experimental diets had no effect on liver S-adenosylhomocysteine (SAH) concentrations or on the S-adenosylmethionine (SAM) to SAH ratio, though the lowest SAM levels were observed in the HF+TP group. No significant differences were detected in blood homocysteine, triglycerides, glucose or insulin levels. CONCLUSIONS: Although RB+TP incorporated into a HF diet may lead to a decrease in AIP and total liver lipid content, this effect does not depend on the components of TP, but rather on the RB ingredients. However, pure TP, in the doses used in this study, may potentially play a role in the energy balance via faecal loss of lipids.

RESUMO

The purpose of this study was to investigate the visual and taste liking of three commercial gluten-free (GF) foods in a group of celiac children. Thirty celiac children, with diagnosis of celiac disease from more than 2 years, were recruited and 28 (21 females and 7 males, mean age 8.7 years) completed the study. Subjects performed individually six sensory tests, two for each product in different days separated by a week. In the test day, children had to evaluate the liking of the same type of product but of different four brands, before and after tasting them with a 5-point facial rating scale. Overall, the results showed that the majority of children appreciated more the appearance than the taste of all the GF products analysed. The present study provides the first and useful indications on the hedonic perceptions of celiac children about some commercial GF products.

RESUMO

The present study investigated the perceptions of individuals with celiac disease about gluten-free (GF) products, their consumer behavior and which product is the most desired. A survey was used to collect information. Descriptive analysis, χ² tests and Multiple Logistic Regressions were conducted. Ninety-one questionnaires were analyzed. Limited variety and availability, the high price of products and the social restrictions imposed by the diet were the factors that caused the most dissatisfaction and difficulty. A total of 71% of the participants confirmed having moderate to high difficulty finding GF products. The logistic regression identified a significant relationship between dissatisfaction, texture and variety (p < 0.05) and between variety and difficulty of finding GF products (p < 0.05). The sensory characteristics were the most important variables considered for actual purchases. Bread was the most desired product. The participants were dissatisfaction with GF products. The desire for bread with better sensory characteristics reinforces the challenge to develop higher quality baking products.

RESUMO

PURPOSE: There is concern about the nutritional quality of processed gluten-free (GF) products. The aim was to investigate the nutrient composition and cost of processed GF products compared with similar regular products. METHODS: Product size, price, caloric value, and macro- and micronutrient composition were compared between foods labeled "Gluten-free" and comparable regular products in 5 grocery stores in 3 Canadian cities. Data were calculated per 100 g of product. RESULTS: A total of 131 products were studied (71 GF, 60 regular). Overall, calories were comparable between GF and regular foods. However, fat content of GF breads was higher (mean 7.7 vs. 3.6 g, P = 0.003), whereas protein was lower (mean 5.0 vs. 8.0 g, P = 0.001). Mean carbohydrate content of GF pasta was higher (78 vs. 74 g, P = 0.001), whereas protein (7.5 vs. 13.3 g, P < 0.001), fibre (3.3 vs. 5.8 g, P = 0.048), iron (9% vs. 25%DV, P < 0.001), and folate content (5% vs. 95%DV, P < 0.001) were lower. Mean price of GF products was $1.99 versus $1.23 for regular products (P < 0.001). CONCLUSIONS: Some commonly consumed packaged GF foods are higher in fat and carbohydrates and lower in protein, iron, and folate compared with regular products. GF products are more expensive. Dietitians should counsel patients on the GF diet regarding its nutritional and financial impact.

RESUMO

The Australian government recently introduced mandatory folic acid fortification of bread to reduce the incidence of neural tube defects (NTDs). The economic evaluation of this policy contained a number of limitations. This study aimed to address the limitations and to reconsider the findings. Cost-effectiveness analysis was used to assess the cost and benefits of mandatory versus voluntary folic acid fortification. Outcomes measures were quality-adjusted life-years (QALYs), life-years gained (LYG), avoided NTD cases, and additional severe neuropathy cases. Costs considered included industry costs and regulatory costs to the government. It was estimated that mandatory fortification would prevent 31 NTDs, whereas an additional 14 cases of severe neuropathy would be incurred. Overall, 539 LYG and 503 QALYs would be gained per year of mandatory compared with voluntary fortification. Mandatory fortification was cost-effective at A$10,723 per LYG and at A$11,485 per QALY. Probabilistic sensitivity analysis showed that at A$60,000 and A$151,000 per QALY, the probability that mandatory fortification was the most cost-effective strategy was 79% and 85%, respectively. Threshold analysis of loss of consumer choice indicated that with a compensation value above A$1.21 [assuming a willingness to pay (WTP) threshold of A$60,000 per QALY] or A$3.19 (assuming a WTP threshold of A$151,000 per statistical life-year) per capita per year mandatory fortification would not be cost-effective. Mandatory fortification was found to be cost-effective; however, inclusion of the loss of consumer choice can change this result. Even with mandatory fortification, mean folate intake will remain below the recommended NTD preventive level.

RESUMO

AIM: Taken into consideration that the deficiency of calcium (Ca) in the diet is a common problem, the aim of this work was to study the chicken eggshell as Ca source at home. It was evaluated: (1) different mechanisms to process eggshells and find an easy way to determine the required amount of Ca at home and; (2) the flavor and the texture for eggshell fortified food. METHODS: Chemical and mechanical methods of eggshell processing were evaluated. Changes in flavor and texture were evaluated in volunteers coordinated by a professional chef. RESULTS: A single eggshell contains 2.07 ± 0.18 g of Ca; therefore half an eggshell could provide the amount of Ca needed by adult human beings per day. The best way to use chicken eggshell as Ca dietary supplement is powdered to add to bread, pizza or spaghetti as there were small changes in texture and no changes in flavor.

RESUMO

BACKGROUND: Grapes are one of the world's staple fruit crops, with about 80% of the yield being utilised for winemaking. Since grape by-products still contain large amounts of secondary metabolites, uses other than as fertilisers might be appropriate. In this study, white grape pomace (WGP) was incorporated in wheat flour at levels of 10, 20 and 30% (w/w) to investigate its influence on rheological, nutraceutical, physical and sensory properties. RESULTS: Farinograph characteristics of dough with different levels of WGP showed a decrease in water absorption from 56.4% (0% WGP) to 45.9% (30% WGP). Addition of WGP reduced hardness and caused a deterioration in brightness and yellowness of all enriched samples. The smallest addition of WGP (10%) caused an approximately 88% increase in total dietary fibre content as compared with the control. The content of phenolic compounds increased from 0.11 mg g⁻¹ with 0% WGP to 1.07 mg g⁻¹ with 30% WGP. The most stable phenols were as follows: γ-resorcylic acid < gallic acid < tyrosol < catechin < isovanilic acid. An assay of radical-scavenging activity showed that WGP addition greatly enhanced the antioxidant properties of biscuits. Acceptable biscuits were obtained when incorporating 10% WGP. CONCLUSION: WGP might be utilised for the novel formulation of biscuits as an alternative source of dietary fibre and phenols.

RESUMO

The effects of ingestion of flaxseed gum on blood glucose and cholesterol, particularly low-density lipoprotein cholesterol, in type 2 diabetes were evaluated. Flaxseed gum was incorporated in wheat flour chapattis. Sixty patients of type 2 diabetes were fed a daily diet for 3 months, along with six wheat flour chapattis containing flaxseed gum (5 g), as per the recommendations of the American Diabetic Association. The control group (60 individuals) consumed an identical diet but the chapattis were without gum. The blood biochemistry profiles monitored before starting the study and at monthly intervals showed fasting blood sugar in the experimental group decreased from 154 ± 8 mg/dl to 136 ± 7 mg/dl (P=0.03) while the total cholesterol reduced from 182 ± 11 mg/dl to 163 ± 9 mg/dl (P=0.03). Results showed a decrease in low-density lipoprotein cholesterol from 110 ± 8 mg/dl to 92 ± 9 mg/dl (P=0.02). The study demonstrated the efficacy of flax gum in the blood biochemistry profiles of type 2 diabetes.

RESUMO

The biscuit industry has evolved in the last decades with the inclusion of alternative cereals, pseudo-cereals and other ingredients in traditional recipes, which allows current consumers' needs to be met. The dough composition, thermal treatment applied during baking, low moisture, and high rate of consumption make biscuits important contributors to daily exposure to acrylamide in Western diets. Acrylamide was determined by LC-ESI-MS/MS in 80 commercial biscuits marketed in Spain. The mean acrylamide content was 343 µg kg-1 (from <20 to 2144 µg kg-1). Rye, teff and oat-based biscuits exhibited the highest content (2144, 1559 and 1424 µg kg-1, respectively). 70% of the samples were below the benchmark level established by the EU Regulation 2017/2158. Compared to our previous prospective study in 2007 on the Spanish market, acrylamide has experienced an important decline (45%) in wheat-based formulations, demonstrating the effectiveness of the mitigation strategies applied in the sector. However, when all samples were considered, a slight non-significant decrease (18%) was observed. This fact suggests that the reformulation of traditional recipes with innovative cereals and ingredients could increase the acrylamide content in biscuits despite the mitigation strategies applied. Therefore, forthcoming reviews of the regulation should consider establishing categories in biscuits according to the main cereal, as has already been established in breakfast cereals.

RESUMO

PURPOSE: The US Department of Agriculture's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) seeks to improve the health of participating women and children by providing nutrition education and a monthly package of supplemental foods including whole grain bread and cereal. While some studies confirm that participants consume more whole grains, others find no effect. In this study, we hypothesize that the positive association between WIC and whole grains is being reduced in size and consistency by several factors. DESIGN/SETTING/PARTICIPANTS: American households were surveyed about their food purchases. Overall response rate was 45.6%. A total of 4826 households completed the survey including 471 WIC households. MEASURES: The survey recorded households' purchases of refined and whole grains in bread and cereal over 1 week. ANALYSIS: T tests were used to compare the bread and cereal purchases of WIC and eligible, non-WIC households. Probit models were also estimated to assess a WIC household's likelihood to choose whole grain foods when using benefits versus other payment methods. RESULTS: On average, WIC households acquired more whole grains in bread than eligible, non-WIC households (1.33 vs 0.72 ounce equivalents per household member aged 1 year or older; P < .05). No difference is found for cereal ( P > .10). Moreover, when using payment methods other than WIC benefits, WIC participants are 19% less likely than other households to choose whole grain bread ( P < .05) and 20% less likely to choose a whole grain cold cereal ( P < .05), which suggests that WIC-provided foods may replace some whole grains participants would otherwise buy for themselves. CONCLUSION: WIC is positively associated with whole grains. However, the association is stronger for bread than cereal. Moreover, foods provided through the program may partially replace whole grains that WIC households would otherwise buy for themselves.

RESUMO

BACKGROUND: In 2009, mandatory folic acid fortification of bread-making flour was introduced in Australia to reduce the birth prevalence of preventable neural tube defects (NTDs) such as spina bifida. Before the introduction of the policy, modelling predicted a reduction of 14-49 NTDs each year. OBJECTIVE: Using real-world data, this study provides the first ex-post evaluation of the cost effectiveness of mandatory folic acid fortification of bread-making flour in Australia. METHODS: We developed a decision tree model to compare different fortification strategies and used registry data to quantify the change in NTD rates due to the policy. We adopted a societal perspective that included costs to industry and government as well as healthcare and broader societal costs. RESULTS: We found 32 fewer NTDs per year in the post-mandatory folic acid fortification period. Mandatory folic acid fortification improved health outcomes and was highly cost effective because of the low intervention cost. The policy demonstrated improved equity in outcomes, particularly in birth prevalence of NTDs in births from teenage and indigenous mothers. CONCLUSIONS: This study calculated the value of mandatory folic acid fortification using real-world registry data and demonstrated that the attained benefit was comparable to the modelled expected benefits. Mandatory folic acid fortification (in addition to policies including advice on supplementation and education) improved equity in certain populations and was effective and highly cost effective for the Australian population.

RESUMO

Microbial fuel cells (MFCs) are a promising clean energy source to directly convert waste chemicals to available electric power. However, the practical application of MFCs needs the increased power density, enhanced energy conversion efficiency and reduced electrode material cost. In this study, three-dimensional (3D) macroporous N, P and S co-doped carbon foams (NPS-CFs) were prepared by direct pyrolysis of the commercial bread and employed as free-standing anodes in MFCs. As-obtained NPS-CFs have a large specific surface area (295.07 m2 g-1), high N, P and S doping level, and excellent electrical conductivity. A maximum areal power density of 3134 mW m-2 and current density of 7.56 A m-2 are generated by the MFCs equipped with as-obtained NPS-CF anodes, which is 2.57- and 2.63-fold that of the plain carbon cloth anodes (areal power density of 1218 mW m-2 and current density of 2.87 A m-2), respectively. Such improvement is explored to mainly originate from two respects: the good biocompatibility of NPS-CFs favors the bacterial adhesion and enrichment of electroactive Geobacter species on the electrode surface, while the high conductivity and improved bacteria-electrode interaction efficiently promote the extracellular electron transfer (EET) between the bacteria and the anode. This study provides a low-cost and sustainable way to fabricate high power MFCs for practical applications.

RESUMO

Management of coeliac disease (CD) requires the removal of gluten from the diet. Evidence of the availability, cost, and nutritional adequacy of gluten-free (GF) bread and pasta products is limited. GF flours are exempt from UK legislation that requires micronutrient fortification of white wheat flour. This study surveyed the number and cost of bread and pasta products available and evaluated the back-of-pack nutritional information, the ingredient content, and the presence of fortification nutrients of GF bread and pasta, compared to standard gluten-containing equivalent products. Product information was collected from four supermarket websites. Standard products were significantly cheaper, with more products available than GF (p < 0.05). GF bread products were significantly higher in fat and fiber (p < 0.05). All GF products were lower in protein than standard products (p < 0.01). Only 5% of GF breads were fortified with all four mandatory fortification nutrients (calcium, iron, niacin, and thiamin), 28% of GF breads were fortified with calcium and iron only. This lack of fortification may increase the risk of micronutrient deficiency in coeliac sufferers. It is recommended that fortification legislation is extended to include all GF products, in addition to increased regulation of the nutritional content of GF foods.
