Healthy Consumption Research Articles

Food spending in the United States during the first year of the COVID-19 pandemic.

The COVID-19 pandemic brought about a significant increase in the unemployment rate and a decline in consumer income. At the same time, the public health responses to the pandemic, such as lockdowns and business closures, disrupted the food supply chain. These pandemic-driven changes could lead to a shift in food spending behaviors and potentially exacerbate the food insecurity situation. Leveraging the nationally representative dataset from the 2017–2020 consumer expenditure surveys, we employ a two-part model to assess the changes in weekly household spending on total food, food-at-home (FAH), and food-away-from-home (FAFH) between the pre-pandemic and pandemic period in the United States. Our finding shows a predicted marginal decline in FAFH expenditure by 33.7% but an increase in FAH spending by 6.9% during the pandemic. The increase in FAH spending could not fully offset the decrease in FAFH spending, leading to a decline in total food spending by 12.6%. The results could provide a basis for future studies on food insecurity, nutrient intake, and healthy consumption during the pandemic.

Optimization of ginger (Zingiber officinale) and cinnamon (Cinnamomum verum) on total phenolics, antioxidant activity and loaf volume of bread

As human awareness increases with healthy consumption patterns, food products can be developed into functional foods, one of which is white bread with the addition of ginger and cinnamon. Ginger and cinnamon have phenolic compounds that act as an antioxidant, but the addition in white bread affect the physicochemical and rheological properties of the dough and the loaf volume of white bread. This study aimed to determine the optimum concentration of ginger and cinnamon to produce white bread with the highest total phenol, antioxidant activity, and loaf volume. The research was established with the Response Surface Methodology method using Central Composite Design withtwo factors: concentration of ginger and cinnamon. Minimum and maximum concentrations used for ginger and cinnamon were 1-3% (flour-based) and 2-4% (flour-based), respectively. The optimum result obtained from the program was ginger and cinnamon, at concentration approximately 2.68% and 4% (flour-based), with total phenolic content of 47.90 mgGAE/100g, antioxidant activity of 32.30%, and loaf volume of 154.29%. Optimum white bread had lower loaf volume than controlled white bread.

Research on the Purchase Intention and Influencing Factors of Brand ecological Agricultural Products

Branding ecological agricultural products can not only meet consumers' demand for high-quality agricultural products, but also an effective way to promote agricultural and rural economic development and achieve sustainable utilization of resources. First, analyze the development and consumption status of brand ecological agricultural products. Secondly, through the analysis of the product cognition, product quality, brand building and consumer purchase intention of the brand ecological agricultural products. Then it is found that: consumer income level, education level, price of brand ecological agricultural products and consumer awareness are important influencing factors of consumers' purchase intention, and the growth environment, cultural background and packaging of agricultural products themselves also have different degrees of influence; Nearly half of consumers maintain a trusting attitude towards all links of the whole industrial chain of branded ecological agricultural products; consumers' purchase intention and decision-making behavior of branded ecological agricultural products are influenced by their family's healthy consumption purpose, purchase channels and information sources. Finally, it is suggested to strengthen the cultivation of brand ecological agricultural products; formulate personalized marketing strategies; carry out various publicity activities to improve consumer awareness; strengthen market supervision; strictly control product quality; reduce production costs to meet public needs.

Development of a blue maize pinole: Optimization of functional ingredients by a D‐optimal mixture design approach

The effect of temperature and toasting time of blue maize was evaluated to develop and optimize a pinole mixture. For toasting, total anthocyanins (TA), polyphenols (TP), antioxidant activity (AA), color, viscosity, and microscopic analysis of starch were determined. With the best conditions, a pinole formulation was developed by adding amaranth, chickpea, chia, and oat through a D-optimal mixture design. High temperature and toasting time decreased the TA, TP, lightness, and viscosity; and increased the AA, color (a*, b*), and starch damage. Toasting at 200°C for 4.5 min was adequate, with TA, color (a*), and viscosity retention of 55.68%, 86.83%, and 81.11%, respectively. All four ingredients had significant effects and the special cubic model described the nutritional, physicochemical, functional, and rheological properties. Optimum pinole mixture (1.0% amaranth, 4.97% chickpea, 7.80% chia, and 4.63%) based on reaching the maximum contents of protein, fiber, AA, and TP, had better properties than a local blue maize pinole. Novelty impact statement This study informs about the importance of establishing the temperature and time conditions for toasting blue maize in order to obtain a base of toasted maize for the formulation of pinole with minimal losses of bioactive compounds and color, but with adequate physical and rheological properties. In addition, contributes to the development of a blue maize pinole with ingredients that improve its color, nutritional, rheological, and functional properties; representing an alternative of healthy consumption.

Preliminary Impacts of a Produce Prescription Program in South Georgia

ObjectivesIdentify short-term changes in food security, dietary patterns, and biometrics following a six-week nutrition education and produce prescription intervention in South Georgia.MethodsThe Open Hand Atlanta Cooking Matters Produce Prescription Program adopts a holistic approach to a nutrition intervention by combining cooking classes, nutrition education, and weekly boxes of local produce over a six-month period. Baseline and six-week program data collected in South Georgia during 2021 were used to examine changes in food security and dietary patterns among program graduates (n = 62).ResultsUsing paired t-tests for numerical outcomes and McNemar's tests for categorical food security, we examined participants’ reported changes in dietary outcomes. After six weeks of nutrition education and receiving local produce boxes, program participants reported increased consumption of dark greens, non-fried vegetables, and beans, alongside reduced consumption of fried foods and meals away from home. However, these changes were not statistically significant among our sample. Similarly, program participants reported non-statistically significant improvements in food security. Composite scores of healthy consumption, healthy purchasing, and resource management all improved from baseline to six-week follow-up with statistically significant improvements in healthy purchasing behaviors.ConclusionsAmong our sample, six weeks of nutrition education and produce receipt resulted in statistically significant changes in healthy purchasing behaviors and improvements across a suite of other dietary variables. Further longitudinal follow-up will examine longer-term changes associated with the produce prescription program.Funding SourcesOpen Hand Atlanta.

Effects of different combinations of probiotics on rheology, microstructure, and moisture distribution of soy materials-based yogurt.

The effects of different probiotics on the texture, rheological properties, microstructure, and water distribution of yogurt fermented with soy powder, soy isolate protein powder, soy umbilical powder, and soy whey as the main raw materials were studied. The soy materials-based yogurt fermented by Danisco mixed probiotic reached the end of fermentation after 4 h, which significantly shortened the fermentation time compared with other probiotic combinations. The fermentation with Danisco mixed probiotic and Kefir mixed probiotic respectively resulted in good texture and a denser and more homogeneous microstructure, which was consistent with the sensory evaluation results. Both fermentations had a high water holding capacity of 90.92% and 78.30%, respectively, in agreement with the results of moisture distribution tests. However, the elastic and viscous behaviors were weaker at certain shear frequency. This study achieved a high value-added utilization of soy whey and the development of a new soy materials-based yogurt that met the consumption needs of people with lactose intolerance and high cholesterol. PRACTICAL APPLICATION: In this study, high value-added utilization of soy whey was realized, which solved the problems of resource waste and environmental pollution. Meanwhile, the research and development of soy materials-based yogurt provided another nutritional and healthy consumption demand for lactose intolerant people.

0095 Sleep Enhancement Technology in 2021: An Updated Survey of Apps

Abstract Introduction Commercially available smartphone apps that claim to improve sleep quantity and/or quality represent an ever-evolving and fast-growing market. Although a large body of work has validated the performance of sleep tracking technologies, there is little information regarding potential sleep enhancement technologies. Our study systematically surveyed currently available commercial sleep enhancement smartphone apps to provide details to inform both providers and patients alike, in addition to the healthy consumer market. Methods We systematically searched the Google Play Store (Android) on 30 JUN 2021 and the App Store (Apple) on 30 JUN 2021 and 26 JUL 2021 in the US using the keyword “sleep.” The Android search was conducted via the Google Play Store website. The Apple search was conducted via third-party websites linked to the App Store due to restrictions on searching the App Store online. This survey was conducted using Google Chrome web browsers and is inclusive of all smartphone applications found. Results We identified 550 apps: 59.5% on Android (N=327) and 40.5% on Apple (N=223). Ninety-four percent of apps offered a free version. The majority of sleep apps were intended for use during wake (72.7% exclusively during wake; 25.1% during both wake and sleep), with only 2.2% intended to be used during sleep alone. Most apps purport to enhance rather than measure sleep (87.8% versus 0.5%). The vast majority of apps claim to enhance sleep via reductions in sleep latency (92.9%). Reduced sleep latency is primarily achieved using auditory stimuli (74.5%). Conclusion Most current sleep apps are designed to be used while awake, prior to sleep, and focus on the enhancement of sleep, rather than measurement, by targeting sleep latency. Given the evidence that supports sleep latency as an important target for sleep promoting interventions and the multitude of available sleep enhancement apps across both Android and Apple platforms, sleep apps could be considered a possible strategy for patients and consumers to improve their sleep, although validation of these apps is required.

Consumer demand for healthy beverages in the hospitality industry: Examining willingness to pay a premium, and barriers to purchase.

This study empirically examines consumer demand for healthy beverages within the hospitality industry. The research investigates sociodemographic and motivational factors that influence consumers' 'willingness to pay a premium' (WTPP) price for healthy beverages using survey data from 1021 consumers in Australia and New Zealand (NZ). Water and juice are rated as representing 'healthy' beverages sold by hospitality businesses. Under 2% of respondents consider sugar free drinks as being healthy. Consumers rate a 'healthy' beverage as having low/no sugar, natural/no additives, or containing vitamins and minerals. Less than 1% of respondents identify 'probiotics' or 'organic' as a healthy beverage. Censored Poisson finds consumers who frequently eat out or are younger have higher WTPP. Healthy eating goals increase WTPP, whereas food economizing goals decreases WTPP. Food hedonism goals reduces consumers' WTPP, and gender differences moderates this relationship. The findings present new insights on consumer behavior and healthy consumption in hospitality.

Contribution of Age and Risky Food Consumptions Towards Heart Disease in Jambi Province

The prevalence of heart disease in Jambi Province has increased. This study aimed to determine the factors associated with heart disease in Jambi Province. This cross-sectional study used secondary data from the 2018 Basic Health Research (Riskesdas). Data regarding age, gender, type of occupation, domicile, smoking status, physical activity, consumption patterns, and Body Mass Index (BMI) from 15483 were analyzed. The relationship between independent variables and heart disease was analyzed bivariately using the Chi Square Test (X2) followed by multivariate analysis using the Multiple Logistics Regression Test. The results showed that the proportion of heart disease in Jambi Province was 0.96%. Factors related to the incidence of heart disease were age (AOR=4.075; 95%CI=2.735-6.073), consumption of sweet foods (AOR=0.367; 95%CI=0.162-0.831), and consumption of processed foods with preservatives (AOR=2.211). ; 95%CI = 1,290-3.789). The dominant factor associated with heart disease in Jambi Province was age (AOR=4,075; 95%CI=2,735-6.073). It is recommended for the community to be able to maintain a healthy consumption pattern to reduce the risk of heart disease.

Determinants and moderators of organic food purchase intention

Researchers have been investigating consumers' purchase intention towards organic food. In this context, this research aimed to propose, test, and validate a theoretical model that considers ecological awareness, healthy consumption, consumer attitude, and little product knowledge as determinants of the intention to purchase organic food. Furthermore, we aimed to analyze the moderating effect of age, frequency of consumption, family size, and individual income on the relationship between consumer attitude and purchase intention. For this purpose, we implemented a survey from a non-probabilistic convenience sample with 532 Brazilian consumers with access to organic food consumption. For data analysis, structural equation modeling was used to test the proposed theoretical model, allowing a better understanding of the purchase intention of organic food from the consumers' perspective. The results showed that ecological awareness, healthy consumption, consumer attitude, and little product knowledge are determinants of organic food purchase intention and that such determinants could explain 78.8% of the variance of organic food purchase intention. It is also noteworthy that individual income and frequency of consumption have a positive moderating effect on the relationship between consumer attitude and the purchase intention of organic food.

Analisis Potensi Pencemaran Air Tanah Di Sekitar TPA Kebon Kongok Dengan Uji MPN Bakteri Coliform.

Water is an essential material in life, water is needed by living things, especially as drinking water. There are many factors that hinder or trigger the availability of clean water to decrease. One of these factors is human activities that can cause problems for the availability of clean water supply for healthy consumption of the community. One of these factors is the existence of a Final Disposal Site (TPA). The final disposal site (TPA) in West Lombok is the Kebon Kongok TPA. This research is a descriptive analytic study. This research was conducted at the Health Testing and Calibration Laboratory Center (BLKPK) of West Nusa Tenggara Province. Well water samples are taken directly at the location, then taken to the laboratory for examination in order to obtain primary data. Sample measurement was carried out using the MPN (Most Probable Number) method which was carried out at the West Nusa Tenggara BLKPK laboratory. Variety II: 5 x 10 ml, 5 x 1 ml, 5 x 0.1 ml. Variety 2 is used for specimens that have not been processed or are thought to have a high germ count. There were 12 samples of well water tested and all of them were positive for coliform bacteria. The number of Coliform bacteria found in the test samples varied. The highest number of bacteria was found in sample 1, which contained Coliform 5400/100 ml of water. This happens because the distance of sample 1 well is only 10 meters from the leachate or leachate waste collection point. All samples of well water tested were already at the threshold of clean water so they were not fit for consumption.

Food Preferences in Undergraduate Nursing Students and Its Relationship with Food Addiction and Physical Activity.

The transition to college is a decisive stage for the acquisition of eating habits that continue into adulthood. The aim of this study is to assess the consumption of healthy elements of the Mediterranean diet in a group of university students and to evaluate whether the consumption pattern was related to sex, Body Mass Index (BMI), food addiction or the amount of physical activity performed. A total of 515 nursing students participated. The Mediterranean diet adherence questionnaire (PREDIMED), the food addiction scale (YFAS 2.0) and the International Physical Activity Questionnaire (IPAQ) were completed. For data analysis, multivariate analysis was performed with multiple linear regression and adjusted for sex, age, and BMI. The results showed that females consumed various types of meats (white/red, processed) in a healthier proportion (p < 0.05). Students that consumed more than one per day (unhealthy) of red/processed meats (mean difference (MD) = −0.49; 95% CI: −0.83; −0.15), soft drinks (MD = −0.82; 95% CI: 82–1.36; −0.27) and pastries (MD = −0.63; 95% CI: −0.97; −0.30) displayed higher food addiction scores. In addition, students who skipped breakfast also scored higher on food addiction (MD = 0.75; 95% CI: 0.31–1.19). Higher values of physical activity were observed in those who presented a healthy consumption of vegetables (MD = 140.86; 95% CI: 72.71–209.02), fruit (MD = 145.78; 95% CI: 69.35–222.21), legumes (MD = 136.46; 95% CI: 60.43–212.50) and nuts (MD = 74.36; 95% CI: 14.23–134.49). Students who consumed more red or processed meats, more pastries and more soft drinks had higher values of food addiction, while those who consumed more vegetables, fruits, legumes, and nuts had more minutes of physical activity per week. These findings invite us to insist on expanding knowledge regarding the health benefits of consuming a Mediterranean-type diet as a whole. The healthy consumption of fish, fruit and legumes should also be emphasized, especially among university students.

Tingkat Pengetahuan Masyarakat tentang Perilaku Hidup Bersih dan Sehat di Desa Rumengkor Kabupaten Minahasa

Background:&#x0D; Clean and Healthy Lifestyle (PHBS) is very important for health, life, and development. Worldwide an estimated 2.4 billion people still lack basic sanitation. PHBS is a concern for the government because it becomes a benchmark for increasing health coverage in the SDGs program in 2015-2030. PHBS and SDGs are one of the prevention efforts that can have a short-term impact on improving health, including the family, the general public, and schools. The knowledge and awareness of the community, especially the people who live in the village are still relatively low to get used to having a clean and healthy life. The purpose of this study was to determine the level of public knowledge about PHBS in Rumengkor Village, Minahasa Regency.&#x0D; Method:&#x0D; Descriptive quantitative to describe the level of community knowledge about PHBS. The sample was the people of Rumengkor Village, Minahasa Regency, who are respondents from 78 people, which are determined using purposive sampling. Data were obtained by interview and using demographic characteristics questionnaire and PHBS questionnaire.&#x0D; Results:&#x0D; In general, the level of public knowledge about PHBS for clean water facilities, the availability of healthy latrines, waste disposal, fruit and vegetable consumption is good, but the level of knowledge about smoking habits is still very low.&#x0D; Conclusion:&#x0D; The results of this study illustrate the level of community knowledge about PHBS in Rumengkor Village is quite good. It's just that PHBS related to smoking habits are still relatively lacking. This happens because most of the respondents and family members are active or passive smokers. Recommendations for health workers are expected to be more active in providing health education in easily accessible language so that people can understand and make good use of the information received.

The interaction of social influence and message framing on children’s food choice

PurposeObesity leads to increased mortality and morbidity among children, as well as when they turn adults. Melding marketing theories in social influence and message framing, this study aims to examine how compliance versus conformance social influence, each framed either prescriptively or proscriptively, may guide children’s choice of healthy versus unhealthy food.Design/methodology/approachThis study conducted two experiments in a Pakistani junior school. Experiment 1 exposed children to either a prescriptive or a proscriptive compliance influence. Experiment 2 involved a 2 (prescriptive vs proscriptive compliance influence) × 2 (supportive vs conflicting conformance-influence) between-subjects design. Participants in both studies answered an online survey after being exposed to the social-influence messages.FindingsExperiment 1 showed proscriptive was stronger than prescriptive compliance influence in nudging children to pick fruits (healthy) over candies (unhealthy). However, frequency of fruits dropped as susceptibility to compliance strengthened. Experiment 2 found that a proscriptive compliance influence reinforced by a supportive conformance-influence led to most children picking fruits. However, a conflicting conformance influence was able to sway some children away from fruits to candies. This signalled the importance of harmful peer influence, particularly with children who were more likely to conform.Research limitations/implicationsChildhood is a critical stage for inculcating good eating habits. Besides formal education about food and health, social influence within classrooms can be effective in shaping children’s food choice. While compliance and conformance influence can co-exist, one influence can reinforce or negate the other depending on message framing.Practical implicationsIn developing countries like Pakistan, institutional support to tackle childhood obesity may be weak. Teachers can take on official, yet informal, responsibility to encourage healthy eating. Governments can incentivise schools to organise informal activities to develop children’s understanding of healthy consumption. Schools should prevent children from bringing unhealthy food to school, so that harmful peer behaviours are not observable, and even impose high tax on unhealthy products or subsidise healthy products sold in schools.Originality/valueThis study adopts a marketing lens and draws on social influence and message framing theory to shed light on children’s food choice behaviour within a classroom environment. The context was an underexplored developing country, Pakistan, where childhood obesity is a public health concern.

Metals in Ten Commercial Demersal Fish from the East China Sea: Contribution to Aquatic Products Nutrition and Toxic Risk Assessment.

Metal accumulation in the marine environment can increase the metal content of fish living in it. For this reason, it is essential to evaluate the nutrition from fish consumption and assess metal toxicity risk. Ten species of demersal fish, which are part of the daily diet of coastal residents, were sampled using trammel net in the East China Sea. Levels of themicroelements, the constant elements, and the toxic elements of muscle tissue were analyzed. Spiny red gurnard had the highest concentrations of calcium, copper, and iron, whereas pufferfish and threadfin porgy were good sources of zinc and magnesium. The levels of lead, cadmium, and inorganic arsenic in all samples were below the limit values according to Chinese national standards. Although some concerns were raised about the concentration of mercury (Hg) in threadfin porgy, silver croaker, and fivespot flounder, molar ratios (selenium, Se:Hg) and the Se health benefit values (HBVSe) indicated that they were safe for human consumption. Additionally, the estimated weekly intake and % weekly contribution of 10 fish species with different elements were provided, giving a reference for the people's healthy consumption.

Networks under Deep Uncertainty

We construct a model to find the insecure countries in terms of food security using network analysis under the conditions of deep uncertainty. The conditions under deep uncertainty can be drought, flood, earthquakes, etc., which affect the supply and demand of food of the countries. Under such conditions which countries are more vulnerable has been studied. In order to study such situations, a model for healthy consumption of different products has been built, and a network is constructed to determine the vulnerable countries using the import and export data of basic food products (Rice, Wheat, Maize, Sorghum, Barley and Rye) for various countries. Different measures of network analysis have been applied and studied to discover the dependency of one country from other country or countries for food supply. The result of the study will definitely be helpful to the countries to resist such threats beforehand.

COVID-19 Lockdown Home Gardening in the Western Province of Sri Lanka

Sampling a set of households from three districts of the Western Province, this paper explored the landscape of lockdown home gardening which took place during the first wave of the COVID-19 pandemic in Sri Lanka. A structured questionnaire published online enabled collecting 939 household responses. A descriptive analysis performed using the IBM SPSS package highlights that the lockdown conditions have intensified the level of home gardening of the participants. The study validates the findings from recent studies that home gardening has no dividing line when it comes to the socio-economic character of households. Primary benefit of home gardening is of households’ being in seek of good and healthy consumption, vegetables and fruits have been the most preferred crop types to grow. Application of organic fertiliser have been preferred by the majority of the households. This study supports the notion that urban land scarcity is not a limiting factor for home gardening. The paper suggests that this home gardening trend reignited during the Covid-19 lockdown needs to be supported by three means: promoting healthy lifestyles, connecting government officials with local home gardeners and local plans being supportive and appreciative of home gardening.

Association between lifestyle and emotional aspects of food consumption during the COVID-19 pandemic

Background and aimsAdequate nutrition during infectious outbreaks require a personal management strategy, especially when there are emotional factors involved. To evaluate the association between lifestyle and emotional aspects of food consumption during the pandemic COVID-19. Methods and resultsCross-sectional study using online self-applied questionnaire with 15,372 active schoolteachers who worked in primary education (kindergarten, elementary and high school) from Minas Gerais, Brazil. Poisson Regression model with robust variance was used to determine the association between lifestyle and emotional aspects and food consumption. Greater adherence to the healthy consumption profile showed a statistically significant association with decreased weight (PR = 1.58; p = 0.000), decreased physical activity (PR = 1.27; p = 0.000), reduced income, (PR = 1.26; p = 0.000), reduced alcohol consumption (PR = 1.22; p = 0.000), and changes in mental health (PR = 1.19; p = 0.000). Unhealthy consumption profile was significantly correlated with weight gain (PR = 1.54; p = 0.000), consuming more alcohol, or started drinking during the pandemic (PR = 1.44; p = 0.000), increased physical activity (PR = 1.43; p = 0.000); increased cigarette consumption (PR = 1.17; p = 0.000), and being a younger adult (PR = 1.17; p = 0.000). ConclusionsThe COVID-19 pandemic influenced the food profiles of basic education teachers in the Minas Gerais state education system in a bidirectional manner, favoring the practice of consuming healthy or unhealthy foods.

Factors Influencing Brain Healthy Diets Among Older Midwestern African Americans

This study describes the feasibility and patient satisfaction for an integrated treatment to address multiple health outcomes in a sample of older adults living in a low-income independent residence facility and their own homes in the community. Specifically, 30 older adults were offered the opportunity to participate in a feasibility study of different components of Activate for Life treatment targeting balance and physical strength (Otago Exercise Program), breathing retraining (Gentle Yoga and Yogic Breathing), and mental health (Behavioral Activation for Depression). Three treatment combinations were compared in a randomized repeated measures design to determine if adding components to the existing Otago program were feasible and if this affected patient satisfaction. Arm1: the Otago strength and balance program alone (n = 10); Arm 2: Otago + Gentle Yoga and Yogic Breathing (n = 10); and Arm 3: Otago + Gentle Yoga and Yogic Breathing + Behavioral Activation (we named this combination ‘Activate for Life’ n = 10). Dependent measures included recruitment rate, session completion characteristics, and satisfaction with the program. Overall, study and treatment components proved feasible, and participants reported high satisfaction with all 3 Arms.

Is Dietary Iodine Intake Excessive According to the Theoretical Model of Healthy Dietary Intake Pattern in Pregnant Women and Schoolchildren: Water, Salt, or Food?

Introduction: Iodine deficiency during pregnancy can cause hypothyroidism and goiter; in schoolchildren, it can cause reduced intelligence quotient. In excess, iodine can cause thyroiditis, goiter, and Hashimoto's hypothyroidism. Currently, schoolchildren and pregnant women are classified as risk groups for excessive iodine intake and iodine deficiency, respectively. Thus, determining iodine from all sources of consumption is important for intervention planning.Objective: To construct a theoretical model for the iodine intake of schoolchildren and pregnant women of a city in the Zona da Mata Mineira region, considering a healthy diet, salt consumption and water intake.Methodology: The dietary iodine intake of pregnant women was analyzed based on a dietary iodine table compiled from an international database. A dietary plan was prepared following the Brazilian Food Guide. Iodine concentration of different salt brands sold in local establishments was checked, and drinking water samples from healthcare facilities were analyzed. A descriptive and exploratory statistical analysis was performed and the results were presented in absolute and relative frequencies, and measures of central tendency and dispersion.Results: According to the proposed diet, pregnant women and schoolchildren would have a daily intake of 71.6 μg and 71 μg, respectively. Thirteen salt brands were evaluated, 69.2% complied with the legislation and the mean iodine content was 29.88 mg. The mean concentration of iodine in water was 25 μg iodine/liter and 14 μg iodine/liter, respectively, in summer and autumn. Considering the intake of food, salt, and drinking water according to the proposed dietary plan, the daily intake for pregnant women would be 279.5 and 253.5 μg for schoolchildren.Conclusion: The daily iodine intake of schoolchildren and pregnant women according to this theoretical model was excessive, considering a healthy dietary pattern. This theoretical model can guide actions and public policies aimed at targeting all forms of iodine intake.
