[PMID: 38584814 PMCID: PMC10995771 DOI: 10.4162/nrp.2024.18.2.294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 10/30/2023] [Accepted: 03/22/2024] [Indexed: 04/09/2024] Open
Abstract
BACKGROUND/OBJECTIVES Dietitians frequently use nutrition education tools to facilitate dietary counselling sessions. Nevertheless, these tools may require adaptation to keep pace with technological advancements. This study had a 2-fold purpose: first, to identify the types of nutrition education tools currently in use, identify their limitations, and explore dietitians' perspectives on the importance of these tools; second, to investigate the features that dietitians prefer in digital nutrition education tools. SUBJECTS/METHODS A semi-structured face-to-face interview was conducted among 15 dietitians from selected public hospitals, primary care clinics, and teaching hospitals in Malaysia. Inductive thematic analysis of the responses was conducted using NVivo version 12 software. RESULTS Most dietitians used physical education tools including the healthy plate model, pamphlets, food models, and flip charts. These tools were perceived as important as they facilitate the nutrition assessment process, deliver nutrition intervention, and are time efficient. However, dietitians described the current educational tools as impersonal, outdated, limited in availability due to financial constraints, unhandy, and difficult to visualise. Alternatively, they strongly favoured digital education tools that provided instant feedback, utilised an automated system, included a local food database, were user-friendly, developed by experts in the field, and seamlessly integrated into the healthcare system. CONCLUSION Presently, although dietitians have a preference for digital educational tools, they heavily rely on physical nutrition education tools due to their availability despite the perception that these tools are outdated, impersonal, and inconvenient. Transitioning to digital dietary education tools could potentially address these issues.

Abstract
Background Sugar-sweetened beverages are one of the most common sources of added sugar in the diet and have been associated with an increased risk of dental caries, obesity, major chronic diseases, and possibly cancer. Dental caries is a diet-related, highly prevalent, and preventable oral disease. The objective of this study was to assess the frequency of sugar-sweetened beverage consumption and its association with dental caries in adolescents in Erbil, Iraq. Methods This is a cross-sectional study that invited 11- to 16-year-old intermediate school students (n=380) in Erbil, Iraq. Data collection comprised a validated questionnaire and a clinical examination. In addition, dietary data were collected by using two non-consecutive 24-hour recalls. The mean of the daily consumption of sugar-sweetened beverages over a two-day period was calculated. Dental caries was diagnosed based on World Health Organization (WHO) criteria and was reported as a decayed, missing, and filled permanent tooth (DMFT). A multiple regression model was used to assess the influence of sugar-sweetened beverages on dental caries experience (DMFT). SPSS version 26 (Armonk, NY: IBM Corp) was used to analyze the data at the 5% significance level. Results Of the 380 students interviewed, one participant was excluded because of incomplete data. The participant's mean age and standard deviation (SD) were 13.3±1.2. A total of 54.1% of the students were female. The mean daily intake of sugar-sweetened beverages was 686.71±197.50 mL per day. Male students consumed more beverages than female students (p<0.001). The most frequently consumed sugar-sweetened beverages were sweetened tea and coffee, and the least frequently consumed beverages were milk and dairy products. The mean decayed, missing, and filled permanent tooth (DMFT) was 94.58±2.73. Results of multiple regression analysis showed that caries experience (DMFT) was associated with insufficient toothbrushing (p<0.001), plaque-affected sextants (p=0.001), and male sex (p=0.016). The model also showed a significant association between sugar-sweetened beverage consumption and dental caries experience (DMFT) (regression coefficient=0.008, CI: 0.006-0.009, p<0.001). Conclusions Adolescents in Erbil, Iraq, consumed sugar-sweetened beverages on a frequent basis, and male students consumed more sugary beverages than females. The higher frequency of these beverage consumptions was associated with a higher dental caries experience. Consequently, reducing sugar-sweetened beverage consumption could have a significant positive public health impact.

Abstract
Background: Food frequency questionnaire (FFQ) is the most frequently used dietary assessment method in estimating dietary intakes in epidemiological studies. Aim: This study aimed to assess the relative validity of a semiquantitative FFQ in evaluating dietary intake among pregnant women in the United Arab Emirates. Methods: Within the Mutaba'ah study, a subsample of 111 pregnant women completed a semiquantitative FFQ and a single 24-hour dietary recall (24-HDR) regarded as the reference method. Absolute and energy-adjusted nutrient and food intakes between the FFQ and 24-HDR were compared using the Wilcoxon signed ranks test, correlations, Bland-Altman analysis, cross-classification, and weighted kappa analysis. Results: There were no significant differences in reported absolute intakes between the FFQ and 24-HDR for carbohydrates, whole grains, white meat, beta-carotene, vitamin K, sodium, and selenium. Spearman's correlation coefficients between the FFQ and 24-HDR ranged from 0.09 (trans fatty acids) to 0.5 (potassium) for absolute intakes. Correlation decreased after energy adjustment. Bland-Altman analysis showed that the FFQ overestimated intakes compared with 24-HDR and that the limits of agreement were wide. The average percentage of pregnant women classified into the same or adjacent quartile of intake by both methods was 73%. Weighted kappa values ranged from -0.02 (white meat) to 0.33 (magnesium). Conclusion: Our findings showed that the semi-quantitative FFQ is a useful tool in ranking pregnant women from the Emirati population according to their dietary intake. However, the validity of some estimated intakes was poor; hence, certain intakes should be interpreted with caution.

Evaluation of Acceptability, Functionality, and Validity of a Passive Image-Based Dietary Intake Assessment Method in Adults and Children of Ghanaian and Kenyan Origin Living in London, UK. Nutrients 2023; 15:4075.

Abstract
BACKGROUND Accurate estimation of dietary intake is challenging. However, whilst some progress has been made in high-income countries, low- and middle-income countries (LMICs) remain behind, contributing to critical nutritional data gaps. This study aimed to validate an objective, passive image-based dietary intake assessment method against weighed food records in London, UK, for onward deployment to LMICs. METHODS Wearable camera devices were used to capture food intake on eating occasions in 18 adults and 17 children of Ghanaian and Kenyan origin living in London. Participants were provided pre-weighed meals of Ghanaian and Kenyan cuisine and camera devices to automatically capture images of the eating occasions. Food images were assessed for portion size, energy, nutrient intake, and the relative validity of the method compared to the weighed food records. RESULTS The Pearson and Intraclass correlation coefficients of estimates of intakes of food, energy, and 19 nutrients ranged from 0.60 to 0.95 and 0.67 to 0.90, respectively. Bland-Altman analysis showed good agreement between the image-based method and the weighed food record. Under-estimation of dietary intake by the image-based method ranged from 4 to 23%. CONCLUSIONS Passive food image capture and analysis provides an objective assessment of dietary intake comparable to weighed food records.

Abstract
Automatic food portion size estimation (FPSE) with minimal user burden is a challenging task. Most of the existing FPSE methods use fiducial markers and/or virtual models as dimensional references. An alternative approach is to estimate the dimensions of the eating containers prior to estimating the portion size. In this article, we propose a wearable sensor system (the automatic ingestion monitor integrated with a ranging sensor) and a related method for the estimation of dimensions of plates and bowls. The contributions of this study are: 1) the model eliminates the need for fiducial markers; 2) the camera system [automatic ingestion monitor version 2 (AIM-2)] is not restricted in terms of positioning relative to the food item; 3) our model accounts for radial lens distortion caused due to lens aberrations; 4) a ranging sensor directly gives the distance between the sensor and the eating surface; 5) the model is not restricted to circular plates; and 6) the proposed system implements a passive method that can be used for assessment of container dimensions with minimum user interaction. The error rates (mean ± std. dev) for dimension estimation were 2.01% ± 4.10% for plate widths/diameters, 2.75% ± 38.11% for bowl heights, and 4.58% ± 6.78% for bowl diameters.

Abstract
Access to good nutritional health is one of the principal objectives of current society. Several e-services offer dietary advice. However, multifactorial and more individualized nutritional recommendations should be developed to recommend healthy menus according to the specific user's needs. In this article, we present and validate a personalized nutrition system based on an application (APP) for smart devices with the capacity to offer an adaptable menu to the user. The APP was developed following a structured recommendation generation scheme, where the characteristics of the menus of 20 users were evaluated. Specific menus were generated for each user based on their preferences and nutritional requirements. These menus were evaluated by comparing their nutritional content versus the nutrient composition retrieved from dietary records. The generated menus showed great similarity to those obtained from the user dietary records. Furthermore, the generated menus showed less variability in micronutrient amounts and higher concentrations than the menus from the user records. The macronutrient deviations were also corrected in the generated menus, offering a better adaptation to the users. The presented system is a good tool for the generation of menus that are adapted to the user characteristics and a starting point to nutritional interventions.

Abstract
OBJECTIVE Undernutrition, stunted growth and obesity remain a concern in Algeria. Currently, limited data are available on nutrient intakes among children. Our study aimed to describe food and nutrient intakes and the role of milk formulas among Algerian children. DESIGN Dietary intakes were collected using a 4-d interview-based survey for children aged 0-24 months, living in urban areas in Algeria in 2019. SETTING Food consumptions were described. For children aged 6-24 months, nutrient intakes and adequacy were estimated. Modelling was used to estimate the nutritional impact of substituting cow's milk for age-appropriate infant formulas (IF). PARTICIPANTS Totally, 446 children aged 0-24 months. RESULTS Before 6 months, 91·6 % of infants were breastfed. Breastmilk was also the main milk consumed between 6 and 12 months, whereas cow's milk predominated after 12 months. In children aged 6-24 months, nutrient adequacy prevalence was above 75 % for the majority of nutrients. However, less than 30 % of the children had adequate intakes for total fats, Fe and vitamin D. Simulated substitution of cow's milk for IF led to improved adequacy for proteins, Fe, and vitamins D and E. CONCLUSIONS Our study showed that breast-feeding rates were high until 6 months, then declined with age. Consumed foods allowed Algerian children aged 6-24 months to meet most of their nutritional needs, but inadequate intakes were reported for some key nutrients. Our modelling suggested that milk formulas may help to improve nutrient adequacy among non-breastfed infants. Other dietary changes could also be further investigated to enable children to meet all nutritional recommendations.

Abstract
This study aimed to develop a digital photographic food atlas as a portion size estimation aid. Commonly consumed foods were identified from the 5512-day weighed dietary records of 644 Japanese adults. Portion sizes were determined based on the market research and distribution of food consumption in the dietary records. Each food item was classified into one of two photo types: a series of photographs showing gradually increasing portion sizes or guide photographs representing a range of portion sizes and food varieties in one photograph. Photographs of the food were taken at an angle of 42°, along with appropriate reference objects such as chopsticks. In total, 209 food and dish items were included in the food atlas. Series of photographs were taken for 105 items that are not usually served in predetermined amounts (e.g., rice and pasta), whereas guide photographs were taken for 104 items usually served in predetermined amounts (e.g., bananas and cookies). Moreover, photographs were taken for 12 kinds of household measurement items, such as cups and glasses. The food atlas could be a valuable tool for estimating the portion size in dietary surveys. Evaluating the validity of this food atlas for portion size estimation is warranted.

Abstract
We evaluated the accuracy of the estimated serving size using digital photographs in a newly developed food atlas. From 209 food items in the food atlas, we selected 14 items with various appearances for evaluation. At the study site, fifty-four participants aged 18-33 years were served fourteen foods in the amount they usually ate. After they left, each food item was weighed by a researcher. The following day, the participants estimated the quantity of each food they served based on food photographs using a web-based questionnaire. We compared the weights of the foods the participants served (true serving sizes) and those determined based on the photographs (estimated serving sizes). For ten of the fourteen food items, significant differences were observed between the estimated and true serving sizes, ranging from a 29⋅8 % underestimation (curry sauce) to a 34⋅0 % overestimation (margarine). On average, the relative difference was 8⋅8 %. Overall, 51⋅6 % of the participants were within ±25 % of the true serving size, 81⋅9 % were within ±50 % and 93⋅4 % were within ±75 %. Bland-Altman plots showed wide limits of agreement and increased variances with larger serving sizes for most food items. Overall, no association was found between estimation errors and participant characteristics. The food atlas has shown potential for assessment of portion size estimation. Further development, refinement and testing are needed to improve the usefulness of the digital food photographic atlas as a portion size estimation aid.

Abstract
Malnutrition is common among dialysis patients, but there is insufficient literature on the problem from resource-poor settings of the sub-Saharan region. We conducted a cross-sectional investigation of dietary intake and nutritional status of haemodialysis (HD) patients to inform the current status of this population group in the region. HD patients aged ≥18 years, with dialysis vintage of ≥3 months, at one nephrology unit in Tanzania were assessed for their habitual diet and nutrient intake. Anthropometric measures and biochemistry tests were also performed. The diet was predominantly starchy food based, accompanied by a limited selection of vegetables. Fruits and animal protein were also minimally consumed (1 portion/day each). Fruit consumption was higher in females than males (median (25th, 75th) = 2 (1, 2.3) versus 0.5 (0, 1.7) portions, p = 0.008). More than 70% of participants had suboptimal measures for protein and energy intake, dietary iron, serum albumin, muscle mass, and hand grip strength (HGS). Inadequacies in protein and energy intake and dialysis clearance (URR) increased with the increase in body weight/BMI and other specific components (MAMC and FMI). Consumption of red meats correlated significantly and positively with serum creatinine (r = 0.46, p = 0.01), potassium (r = 0.39, p = 0.03), and HGS (r = 0.43, p = 0.02) and was approaching significance for a correlation with serum iron (r = 0.32, p = 0.07). C-RP correlated negatively with albumin concentration (r = -0.32, p = 0.02), and participants with C-RP within acceptable ranges had significantly higher levels of haemoglobin (p = 0.03, effect size = -0.28). URR correlated negatively with haemoglobin concentration (r = -0.36, p = 0.02). Patients will benefit from improved nutritional services that deliver individually tailored and culturally practical dietary advice to enable them to make informed food choices whilst optimizing disease management.

Local Foods Can Increase Adequacy of Nutrients Other than Iron in Young Urban Egyptian Women: Results from Diet Modeling Analyses. J Nutr 2021; 151:1581-1590. [PMID: 33693946 PMCID: PMC8169812 DOI: 10.1093/jn/nxab021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 10/07/2020] [Accepted: 01/21/2021] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Nutrition transition and recent changes in lifestyle in Middle Eastern countries have resulted in the double burden of malnutrition. In Egypt, 88% of urban women are overweight or obese and 50% are iron deficient. Their energy, sugar, and sodium intakes are excessive, while intakes of iron, vitamin D, and folate are insufficient. OBJECTIVE This study aimed to formulate dietary advice based on locally consumed and affordable foods and determine the need for fortified products to meet the nutrient requirements of urban Egyptian women. METHODS Food intakes were assessed using a 4-d food diary collected from 130 urban Egyptian women aged 19-30 y. Food prices were collected from modern and traditional markets to calculate diet cost. Population-based linear and goal programming analyses (Optifood tool) were used to identify "limiting nutrients" and to assess whether locally consumed foods (i.e., consumed by >5% of women) could theoretically improve nutrient adequacy at an affordable cost (i.e., less than or equal to the mean diet cost), while meeting recommendations for SFAs, sugars, and sodium. The potential of hypothetical fortified foods for improving intakes of micronutrients was also assessed. RESULTS Iron was the most limiting nutrient. Daily consumption of fruits, vegetables, milk or yogurt, meat/fish/eggs, and tahini (sesame paste) were likely to improve nutrient adequacy for 11 out of 12 micronutrients modeled. Among fortified foods tested, iron-fortified rice, milk, water, bread, or yogurt increased the minimized iron content of the modeled diet from 40% to >60% of the iron recommendation. CONCLUSIONS A set of dietary advice based on locally consumed foods, if put into practice, can theoretically meet requirements for most nutrients, except for iron for which adequacy is harder to achieve without fortified products. The acceptability of the dietary changes modeled needs evaluation before promoting them to young Egyptian women.

Abstract
A photographic food atlas is a series of photographs showing different quantities of different foods. It serves as a portion size estimation aid (PSEA). In Malaysia, the existing food atlases, which display foods in exchanges and standard portion sizes, may not be representative of the actual sizes of the portions of food consumed by the local population. This paper aims to describe the development of a food atlas, namely the 'MY Food Album', and assess its usability as a PSEA. Thirty four participants (aged 31.6±20.9 y) served themselves, in a laboratory setting, what they considered to be typical, small, medium, and large portions of 23 amorphus food items. All food portions were weighed to obtain the mean and standard deviation of the range of food portion sizes to be displayed in the food atlas. Using standard camera and lighting settings, various local foods were photographed at an angle of 45º. A total of 393 food items were categorized into 14 food groups and presented as serial (n=101), guide (n=213) and range (n=79) photographs. The usability of MY Food Album was evaluated by six nutritionists and dietitians using an adapted questionnaire. The food atlas was perceived to be useful to aid in the quantification of food during dietary assessment. It was suggested that the function, dimension and application of fiducial markers be introduced in the food atlas to facilitate its use in size estimation. While MY Food Album was well-accepted as a PSEA, futher validation is required to evaluate the effectiveness of this newly developed food atlas in portion size estimation.

Abstract
AbstractObjective:To validate digitally displayed photographic portion-size estimation aids (PSEA) against a weighed meal record and compare findings with an atlas of printed photographic PSEA and actual prepared-food PSEA in a low-income country.Design:Participants served themselves water and five prepared foods, which were weighed separately before the meal and again after the meal to measure any leftovers. Participants returned the following day and completed a meal recall. They estimated the quantities of foods consumed three times using the different PSEA in a randomized order.Setting:Two urban and two rural communities in southern Malawi.Participants:Women (n 300) aged 18–45 years, equally divided by urban/rural residence and years of education (≤4 years and ≥5 years).Results:Responses for digital and printed PSEA were highly correlated (>91 % agreement for all foods, Cohen’s κw = 0·78–0·93). Overall, at the individual level, digital and actual-food PSEA had a similar level of agreement with the weighed meal record. At the group level, the proportion of participants who estimated within 20 % of the weighed grams of food consumed ranged by type of food from 30 to 45 % for digital PSEA and 40–56 % for actual-food PSEA. Digital PSEA consistently underestimated grams and nutrients across foods, whereas actual-food PSEA provided a mix of under- and overestimates that balanced each other to produce accurate mean energy and nutrient intake estimates. Results did not differ by urban and rural location or participant education level.Conclusions:Digital PSEA require further testing in low-income settings to improve accuracy of estimations.

Abstract
OBJECTIVE To investigate preferences for and ease-of-use perceptions of different aspects of printed and digitally displayed photographic portion-size estimation aids (PSEA) in a low-resource setting and to document accuracy of portion-size selections using PSEA with different visual characteristics. DESIGN A convergent mixed-methods design and stepwise approach were used to assess characteristics of interest in isolation. Participants served themselves food and water, which were weighed before and after consumption to measure leftovers and quantity consumed. Thirty minutes later, data collectors administered a meal recall using a PSEA and then a semi-structured interview. SETTING Blantyre and Chikwawa Districts in the southern region of Malawi. PARTICIPANTS Ninety-six women, aged 18-45 years. RESULTS Preferences and ease-of-use perceptions favoured photographs rather than drawings of shapes, three and five portion-size options rather than three with four virtual portion-size options, a 45° rather than a 90° photograph angle, and simultaneous rather than sequential presentation of portion-size options. Approximately half to three-quarters of participants found the portion-size options represented appropriate amounts of foods or water consumed. Photographs with three portion sizes resulted in more accurate portion-size selections (closest to measured consumption) than other format and number of portion-size option combinations. A 45° angle and simultaneous presentation were more accurate than a 90° angle and sequential presentation of images. CONCLUSIONS Results from testing PSEA visual characteristics separately can be used to generate optimal PSEA, which can improve participants' experiences during meal recalls.

Abstract
Assessment of portion sizes is an important factor for the accuracy of food consumption surveys. The objective of this study was to develop and validate a food atlas of commonly consumed foods in the Balkan region in order to improve the accuracy of portion size estimation for food consumption surveys. A list of 135 foods and their portion sizes was based on previously conducted food consumption surveys in this region. Food was cooked, measured and served in three or four portion sizes right before being photographed. A validation study was conducted through the visual perception method. Without receiving training on usage of the food picture book, participants were asked to evaluate two portion sizes of 20 selected foods by comparison with a photo series of each food. Portion sizes were evaluated by 18 nutrition professionals and 17 lay individuals who had no nutritional education. Mean differences and the standard deviations of the mean differences (SD) between the portions estimated by each participant and the served portion were calculated. The percentages of participants who selected the correct, adjacent or distant portion size also were calculated. The number of food items that were quantified within the predefined acceptable range (i.e., mean difference < ∣ 0·7 ∣ and SD < 1) was 16 (80%) among lay individuals and 17 (85%) among nutritional professionals. Among 16 photo series that were assessed as "acceptable," the percentage of all participants, who selected the correct picture, was between 44.3 and 82.9%, with an average of 60.2%. Only three foods were assessed correctly by <50% participants. The percentage of participants who selected the correct or adjacent serving size was above 98% for both lay and professional evaluators. This is the first food atlas containing representative foods and recipes commonly consumed in the Balkan region. However, further adjustments of the methodology should include larger number of food items to be tested, involvement of more participants and provision of training for the users of the food atlas. This food atlas could be used in food consumption surveys in the Balkan region after further testing and validation.

Abstract
Although, United Arab Emirates (UAE) has one of the highest prevalence of overweight, obesity and type 2 diabetes in the world, however, validated dietary assessment aids to estimate food intake of individuals and populations in the UAE are currently lacking. We conducted two observational studies to evaluate the accuracy of a photographic food atlas which was developed as a tool for food portion size estimation in the UAE. The UAE Food Atlas presents eight portion sizes for each food. Study 1 involved portion size estimations of 13 food items consumed during the previous day. Study 2 involved portion size estimations of nine food items immediately after consumption. Differences between the food portion sizes estimated from the photographs and the weighed food portions (estimation error), as well as the percentage differences relative to the weighed food portion for each tested food item were calculated. Four of the evaluated food items were underestimated (by -8.9% to -18.4%), while nine were overestimated (by 9.5% to 90.9%) in Study 1. Moreover, there were significant differences between estimated and eaten food portions for eight food items (P<0.05). In Study 2, one food item was underestimated (-8.1%) while eight were overestimated (range 2.52% to 82.1%). Furthermore, there were significant differences between estimated and eaten food portions (P<0.05) for six food items. The limits of agreement between the estimated and consumed food portion size were wide indicating a large variability in food portion estimation errors. These reported findings highlight the need for further developments of the UAE Food Atlas to improve the accuracy of food portion size intake estimations in dietary assessments. Additionally, recalling food portions from the previous day did not seem to increase food portion estimation errors in this study.

Abstract
Background Obtaining reliable food portion size estimations in dietary surveys found to be a difficult task. A food atlas is a set of photograph series depicting different amounts of a particular food, usually bound together in a single volume that can be used to describe portion sizes. By this paper we aim to explain the methods used in developing a photographic food atlas for Sri Lankan adults and to discuss its usage, advantages and limitations. Methods Foods that are commonly consumed in Sri Lanka were recognized by a local nutritional survey, market survey and interviewing nutrition experts. In obtaining food items, certain dishes were prepared according to a standard recipe book while other items were purchased from recognized restaurants and the local market. White color crockery or/with blue color board was used to present the food items and they were photographed by a professional photographer employing a camera setup recommended for food photography. Three types of photographs have been used to illustrate the food items; serial, range and guide. Mainly the serial photographs were taken using two cameras: one fixed at an angle of 5° to capture aerial views, and the other placed at an angle of 45° to represent the view of a person of average height, sitting at a table, looking at a plate on the table in front of him. The liquid portion series were photographed at an angle of 90° to get life-size images. The range and guide photographs were taken free hand so that all the items could be captured in the best way possible. Results A total of 125 foods that are commonly consumed by Sri Lankan adults were selected to be depicted in the atlas; serial photographs of increasing portion sizes (n = 88 foods); range photographs depicting a range of sizes/varieties of a particular food, (n = 11), and guide photographs which represent the brands/types of a certain food item/category available in the market (n = 26). Conclusion The food atlas will be a valuable resource for dietary surveys in Sri Lanka as well as in other South Asian countries where similar foods are consumed.
