RESUMO

This study evaluates the nutritional quality and level of processing of food and beverage products advertised on television channels most watched by children, in Italy. Data were collected over 20 non-consecutive days from the five top channels in Italy. A total of 209 food items were analysed using the Nutri-Score and the NOVA classification. Additionally, compliance with nutritional criteria established by the World Health Organisation (WHO) and the EU-PLEDGE was assessed. Results indicate a high proportion of energy-dense and low nutritional quality foods, with 68% falling into less favourable Nutri-Score categories (C, D, and E), and 61% classified as ultra-processed by NOVA classification. When applying WHO and PLEDGE criteria, 71% and 56% of products, respectively, did not meet nutritional standards. This study underscores the low prevalence of nutritionally adequate products in food advertisements targeting children on Italian television, despite differences found based on methodological variations.

RESUMO

Wnt signaling pathway is an evolutionarily conserved pathway that control embryonic development, adult tissue homeostasis, and pathological processes of organisms throughout life. However, dysregulation of the Wnt signaling is associated with the occurrence of chronic diseases. In comparison with the application of chemical drugs as traditional treatment for chronic diseases, dietary agents have unique advantages, such as less side effects, multiple targets, convenience in accessibility and higher acceptability in long-term intervention. In this review, we summarized current progress in manipulating the Wnt signaling using food components and its benefits in managing chronic diseases. The underlying mechanisms of bioactive food components in the management of the disease progression via the Wnt signaling was illustrated. Then, the review focused on the function of dietary pattern (which might act via combination of foods with multiple nutrients or food ingredients) on targeting Wnt signaling at multiple level. The potential caveats and challenges in developing new strategy via modulating Wnt-associated diseases with food-based agents and appropriate dietary pattern are also discussed in detail. This review shed light on the understanding of the regulatory effect of food bioactive components on chronic diseases management through the Wnt signaling, which can be expanded to other specific signaling pathway associated with disease.

RESUMO

BACKGROUND: Gut microbiome colonization during early life is significant for immunological and physiological development. Maternal microbiome is associated with proper development of infants. The aim of this study was to determine the gut microbiome profiles among Thai healthy pregnant women and its associated factors. METHODS: A multicenter, open trial prospective study was performed at three hospitals in Northern, Central, and Northeastern regions of Thailand. Thai healthy pregnant women attending antenatal clinics were recruited. Fecal samples of subjects at the third trimester of pregnancy were collected with sterilized techniques. The gut microbiome profiles and bacterial diversity were assessed using 16Ss RNA gene sequencing. Demographic data, dietary intake, and anthropometric data were recorded and analyzed. RESULTS: There were 86 healthy pregnant women. The dominant of gut microbiome profiles were Bacteroidetes and Firmicutes. Pregnant women in the Central region had significantly higher of Ruminococcaceae and Lachnospiraceae than those in other regions (p < 0.001). Pregnant women in the Northern region significantly consumed more glutinous rice than those in other regions (p < 0.001). Glutinous rice intake was positively correlated with Bacteroidetes (rho = 0.405, p = 0.01) and negatively correlated with Firmicutes (rho = - 0.440, p = 0.001). Alpha diversity was not correlated with pre-pregnancy body mass index (BMI) or gestational weight gain. CONCLUSIONS: The gut microbiome profiles mainly found in Thai healthy pregnant women were Bacteroidetes and Firmicutes. The gut microbiome profiles in pregnant women found in this study possibly depended on dietary patterns. Glutinous rice with high amylopectin is probably related to abundance of Bacteroidetes.

RESUMO

BACKGROUND: Proper regulation of feeding is important for an organism's well-being and survival and involves a motivational component directing the search for food. Dissecting the molecular and neural mechanisms of motivated feeding behavior requires assays that allow quantification of both motivation and food intake. Measurements of motivated behavior usually involve assessing physical effort or overcoming an aversive stimulus. Food intake in Drosophila can be determined in a number of ways, including by measuring the time a fly's proboscis interacts with a food source associated with an electrical current in the fly liquid-food interaction counter (FLIC). Here, we show that electrical current flowing through flies during this interaction is aversive, and we describe a modified assay to measure motivation in Drosophila. RESULTS: Food intake is reduced during the interaction with FLIC when the electrical current is turned on, which provides a confounding variable in studies of motivated behavior. Based on the FLIC, we engineer a novel assay, the fly liquid-food electroshock assay (FLEA), which allows for current adjustments for each feeding well. Using the FLEA, we show that both external incentives and internal motivational state can serve as drivers for flies to overcome higher current (electric shock) to obtain superior food. Unlike similar assays in which bitterness is the aversive stimulus for the fly to overcome, we show that current perception is not discounted as flies become more food-deprived. Finally, we use genetically manipulated flies to show that neuropeptide F, an orthologue of mammalian NPY previously implicated in regulation of feeding motivation, is required for sensory processing of electrical current. CONCLUSION: The FLEA is therefore a novel assay to accurately measure incentive motivation in Drosophila. Using the FLEA, we also show that neuropeptide F is required for proper perception or processing of an electroshock, a novel function for this neuropeptide involved in the processing of external and internal stimuli.

RESUMO

BACKGROUND: Adolescent intake of animal products has been proposed to contribute to prostate cancer (PCa) development because of its potentially carcinogenic constituents and influence on hormone levels during adolescence. METHODS: We used data from 159,482 participants in the NIH-AARP Diet and Health Study to investigate associations for recalled adolescent intake of red meat (unprocessed beef and processed red meat), poultry, egg, canned tuna, animal fat and animal protein at ages 12-13 years with subsequent PCa risk and mortality over 14 years of follow-up. Cox proportional hazard regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of total (n = 17,349), advanced (n = 2,297) and fatal (n = 804) PCa. RESULTS: Suggestive inverse trends were observed for adolescent unprocessed beef intake with risks of total, advanced and fatal PCa (multivariable-adjusted P-trends = 0.01, 0.02 and 0.04, respectively). No consistent patterns of association were observed for other animal products by PCa outcome. CONCLUSION: We found evidence to suggest that adolescent unprocessed beef intake, or possibly a correlate of beef intake, such as early-life socioeconomic status, may be associated with reduced risk and mortality from PCa. Additional studies with further early-life exposure information are warranted to better understand this association.

RESUMO

BACKGROUND: Simple proxy indicators are needed to assess and monitor micronutrient intake adequacy of vulnerable populations. Standard dichotomous indicators exist for nonpregnant women of reproductive age and 6-23-mo-old children in low-income countries, but not for 24-59-mo-old children or pregnant or breastfeeding women. OBJECTIVES: This study aimed to evaluate the performance of 2 standard food group scores (FGSs) and related dichotomous indicators to predict micronutrient adequacy of the diet of rural Burkinabe 24-59-mo-old children and women of reproductive age by physiological status. METHODS: A 24-h recall survey was conducted at dry season among 1066 pairs of children and caregivers. Micronutrient adequacy was evaluated by the mean probability of adequacy (MPA) of intake over 11 micronutrients. Proxy indicators were FGS-10 [10 food groups based on the FAO/FHI360 minimum dietary diversity for women (MDD-W) guidelines] and related MDD-W (FGS-10 ≥5); and FGS-7 [7 groups based on the WHO infant and young child (IYC) feeding MDD guidelines] and related MDD-IYC (FGS-7 ≥4). RESULTS: FGS-10 and FGS-7 were similar across children and women (∼3 groups). FGS-10 performed better than FGS-7 to predict MPA in children (Spearman rank correlation = 0.59 compared with 0.50) and women of all 3 physiological statuses (Spearman rank correlation = 0.53-0.55 compared with 0.42-0.52). MDD-W and MDD-IYC performed well in predicting MPA >0.75 in children and MPA >0.6 in nonpregnant nonbreastfeeding (NPNB) women, but a 4-group cutoff for FGS-10 allowed a better balance between sensitivity, specificity, and proportion of correct classification. MPA levels for pregnant and breastfeeding women were too low to assess best cutoff points. CONCLUSIONS: MDD-IYC or an adapted MDD-W (FGS-10 ≥4 instead of FGS-10 ≥5) can be extended to 24-59-mo-old children and NPNB women in similar-diet settings. The inadequacy of micronutrient intakes in pregnant and breastfeeding women warrants urgent action. Micronutrient adequacy predictors should be validated in populations where a higher proportion of these women do meet dietary requirements.

RESUMO

BACKGROUND: The global diet quality score (GDQS) is a simple, standardized metric appropriate for population-based measurement of diet quality globally. OBJECTIVES: We aimed to operationalize data collection by modifying the quantity of consumption cutoffs originally developed for the GDQS food groups and to statistically evaluate the performance of the operationalized GDQS relative to the original GDQS against nutrient adequacy and noncommunicable disease (NCD)-related outcomes. METHODS: The GDQS application uses a 24-h open-recall to collect a full list of all foods consumed during the previous day or night, and automatically classifies them into corresponding GDQS food group. Respondents use a set of 10 cubes in a range of predetermined sizes to determine if the quantity consumed per GDQS food group was below, or equal to or above food group-specific cutoffs established in grams. Because there is only a total of 10 cubes but as many as 54 cutoffs for the GDQS food groups, the operationalized cutoffs differ slightly from the original GDQS cutoffs. RESULTS: A secondary analysis using 5 cross-sectional datasets comparing the GDQS with the original and operationalized cutoffs showed that the operationalized GDQS remained strongly correlated with nutrient adequacy and was equally sensitive to anthropometric and other clinical measures of NCD risk. In a secondary analysis of a longitudinal cohort study of Mexican teachers, there were no differences between the 2 modalities with the beta coefficients per 1 SD change in the original and operationalized GDQS scores being nearly identical for weight gain (-0.37 and -0.36, respectively, P < 0.001 for linear trend for both models) and of the same clinical order of magnitude for waist circumference (-0.52 and -0.44, respectively, P < 0.001 for linear trend for both models). CONCLUSION: The operationalized GDQS cutoffs did not change the performance of the GDQS and therefore are recommended for use to collect GDQS data in the future.

RESUMO

BACKGROUND: The present study aimed to assess micronutrient intake among Greek adults and to identify the main food sources that contribute to it. METHODS: Food consumption data from 2389 participants in the Hellenic National Nutrition and Health Survey (HNNHS), collected with 24-h recalls, was used to calculate micronutrient intakes. Usual nutrient intake was estimated according to the National Cancer Institute method. Nutrient adequacy was estimated using the estimated average requirement (EAR) cut-point method, when available, or adequate intake otherwise. The probability approach was used to determine iron intake adequacy in females of reproductive age. Food group contribution for each nutrient assessed was derived to identify their main food sources. RESULTS: Almost all individuals had vitamin D intake below EAR, whereas vitamins A, E, K and C, as well as potassium intake, were also insufficient in a considerable percentage of the population (>70% in most age groups). Calcium intake was substantially below the EAR for females aged >50 years and males >70 years; the same for magnesium in males >70 years. Furthermore, 50% of females, including those of reproductive age, had intake of folate below EAR. More than 50% of the population (to 79%) exceeded the upper tolerable limit for sodium (2300 mg day-1 ). Food contribution analysis revealed that most vitamins were derived from low-quality foods (i.e. fast-food). CONCLUSIONS: A significant proportion of adults residing in Greece have low nutrient intake and poor food selections. These results provide guidance to public health policy makers for developing strategies to improve the dietary quality in Greece.

RESUMO

BACKGROUND: Accurate estimation of food portion sizes remains an important challenge in dietary data collection. The present study aimed to develop a food atlas with adequate visual reference to improve the accuracy of dietary surveys in China. METHODS: A food atlas for dietary surveys in China was developed using three visual reference systems, namely, regularly placed food portions, the two-dimensional background coordinates and common objects known in daily life. The atlas was validated by estimating a meal before and after using the food atlas, and differences in weight estimation were compared using a paired t-test. In total, 50 college students participated in the study. RESULTS: After determination of food varieties; design of the food display; purchase, processing, cooking and weighing of food; photographing food; post-image processing and data processing, a total of 799 pictures of 303 types of food and two types of tableware were produced. The mean value of food weight estimated with the atlas was closer to the actual weight, and the variation range of these values was smaller and more stable than that estimated without the atlas. The differences estimated before and after using the atlas for all foods were significant (P < 0.05). Comparing the differences in weight before using the atlas, the error ranges of food samples were reduced. CONCLUSIONS: A food atlas has been developed for a retrospective dietary survey in China, which can be used to enable a better understanding of nutritional adequacy in the Chinese population.

RESUMO

Importance: The childhood obesity rate has been steadily rising among US youths during the past 2 decades. Increasing evidence links consumption of ultraprocessed foods to excessive calorie consumption and weight gain, but trends in the consumption of ultraprocessed foods among US youths have not been well characterized. Objective: To characterize trends in the consumption of ultraprocessed foods among US youths. Design, Setting, and Participants: Serial cross-sectional analysis using 24-hour dietary recall data from a nationally representative sample of US youths aged 2-19 years (n = 33 795) from 10 cycles of the National Health and Nutrition Examination Survey (NHANES) from 1999-2000 to 2017-2018. Exposures: Secular time. Main Outcomes and Measures: Percentage of total energy consumed from ultraprocessed foods as defined by NOVA, an established food classification system that categorizes food according to the degree of food processing. Results: Dietary intake from youths were analyzed (weighted mean age, 10.7 years; 49.1% were girls). From 1999 to 2018, the estimated percentage of total energy from consumption of ultraprocessed foods increased from 61.4% to 67.0% (difference, 5.6% [95% CI, 3.5% to 7.7%]; P < .001 for trend), whereas the percentage of total energy from consumption of unprocessed or minimally processed foods decreased from 28.8% to 23.5% (difference, -5.3% [95% CI, -7.5% to -3.2%]; P < .001 for trend). Among the subgroups of ultraprocessed foods, the estimated percentage of energy from consumption of ready-to-heat and -eat mixed dishes increased from 2.2% to 11.2% (difference, 8.9% [95% CI, 7.7% to 10.2%]) and from consumption of sweet snacks and sweets increased from 10.7% to 12.9% (difference, 2.3% [95% CI, 1.0% to 3.6%]), but the estimated percentage of energy decreased for sugar-sweetened beverages from 10.8% to 5.3% (difference, -5.5% [95% CI, -6.5% to -4.5%]) and for processed fats and oils, condiments, and sauces from 7.1% to 4.0% (difference, -3.1% [95% CI, -3.7% to -2.6%]) (all P < .05 for trend). There was a significantly larger increase in the estimated percentage of energy from consumption of ultraprocessed foods among non-Hispanic Black youths (from 62.2% to 72.5%; difference, 10.3% [95% CI, 6.8% to 13.8%]) and Mexican American youths (from 55.8% to 63.5%; difference, 7.6% [95% CI, 4.4% to 10.9%]) than the increase among non-Hispanic White youths (from 63.4% to 68.6%; difference, 5.2% [95% CI, 2.1% to 8.3%]) (P = .04 for trends). Conclusions and Relevance: Based on the NHANES cycles from 1999 to 2018, the estimated proportion of energy intake from consumption of ultraprocessed foods has increased among youths in the US and has consistently comprised the majority of their total energy intake.

RESUMO

BACKGROUND: Minimum Dietary Diversity (MDD) is a widely used indicator of adequate dietary micronutrient density for children 6-23 mo old. MDD food-group data remain underutilized, despite their potential for further informing nutrition programs and policies. OBJECTIVES: We aimed to describe the diets of children meeting MDD and not meeting MDD in India using food group data, nationally and subnationally. METHODS: Food group data for children 6-23 mo old (n = 73,036) from the 2015-16 National Family Health Survey in India were analyzed. Per WHO standards, children consuming ≥5 of the following food groups in the past day or night met MDD: breast milk; grains, roots, or tubers; legumes or nuts; dairy; flesh foods; eggs; vitamin A-rich fruits and vegetables; and other fruits and vegetables. Children not meeting MDD consumed <5 food groups. We analyzed the number and types of foods consumed by children meeting MDD and not meeting MDD at the national and subnational geographic levels. RESULTS: Nationally, children not meeting MDD most often consumed breast milk (84.5%), grains, roots, and tubers (62.0%), and/or dairy (42.9%). Children meeting MDD most often consumed grains, roots, and tubers (97.6%), vitamin A-rich fruits and vegetables (93.8%), breast milk (84.1%), dairy (82.1%), other fruits and vegetables (79.5%), and/or eggs (56.5%). For children not meeting MDD, district-level dairy consumption varied the most (6.4%-79.9%), whereas flesh foods consumption varied the least (0.0%-43.8%). For children meeting MDD, district-level egg consumption varied the most (0.0%-100.0%), whereas grains, roots, and tubers consumption varied the least (66.8%-100.0%). CONCLUSIONS: Children not meeting MDD had low fruit, vegetable, and protein-rich food consumption. Many children meeting MDD also had low protein-rich food consumption. Examining the number and types of foods consumed highlights priorities for children experiencing the greatest dietary deprivation, providing valuable complementary information to MDD.

RESUMO

BACKGROUND: Although dietary intakes and dietary intake patterns (DPs) have been associated with single metabolites, it is unclear whether DPs are also reflected in specific metabolite patterns (MPs). Moreover, the influence of groups of gut bacteria on the relationship between DPs and MPs is underexplored. OBJECTIVES: We aimed to investigate the association of DPs and serum MPs and also the modifying effect of the gut bacteria compositional patterns (BCPs). METHODS: This is a cross-sectional investigation among 225 individuals (median age: 63 y; 53% women) from the European Prospective Investigation into Cancer and Nutrition study. Dietary intakes were assessed by three 24-h dietary recalls, gut bacteria composition was quantified by 16S rRNA gene sequencing, and the serum metabolome was profiled by an untargeted approach. We identified DPs and BCPs by the treelet transform analysis. We modeled associations between DPs and 8 previously published MPs and the modifying effect of BCPs by fitting generalized linear models using DataSHIELD R. RESULTS: We identified 5 DPs and 7 BCPs. The "bread, margarine, and processed meat" and "fruiting vegetables and vegetable oils" DPs were positively associated with the "amino acids" (ß = 0.35; 95% CI: 0.02, 0.69; P = 0.03) and "fatty acids" MPs (ß = 0.45; 95% CI: 0.16, 0.74; P = 0.01), respectively. The "tea and miscellaneous" was inversely associated with the "amino acids" (ß = -0.28; 95% CI: -0.52, -0.05; P = 0.02) and "amino acid derivatives" MPs (ß = -0.21; 95% CI: -0.39, -0.02; P = 0.03). One BCP negatively modified the association between the "bread, margarine, and processed meat" DP and the "amino acids" MP (P-interaction = 0.01). CONCLUSIONS: In older German adults, DPs are reflected in MPs, and the gut bacteria attenuate 1 DP-MP association. These MPs should be explored as biomarkers of these jointly consumed foods while taking into account a potentially modifying role of the gut bacteria.

RESUMO

BACKGROUND: Adolescence offers a window of opportunity to prevent adult obesity and noncommunicable disease risk factors. With the rising prevalence of adolescent obesity over the last 20 y, identifying any changes in dietary risk factors is crucial. OBJECTIVES: We aimed to assess the dietary intake of major nutrients and their food sources in Costa Rican adolescents from 1996 to 2017. METHODS: Means from 3-d food records from adolescents (ages 13-18 y) living in San José (the province with the highest concentration of adolescents in Costa Rica) were obtained in 1996 (n = 276), 2006 (n = 133), and 2017 (n = 818). Differences in consumption of major nutrients and selected food groups by sex and survey period were tested using age- and area-adjusted ANOVAs. RESULTS: In 2017, adolescents consumed significantly (P < 0.05) less saturated and trans fats [saturated: -3.2% of total energy (TE); trans: -1.4% TE], vegetables (-24 g/d), beans (-42 g/d), and white rice (22 g/d) than in 1996. The 2017 adolescents also reported significantly higher consumption of unsaturated fatty acids (MUFAs: up from 8.2% to 15.3% TE; PUFAs: up from 5.5% to 9.5% TE; P < 0.05), sugary drinks (+134 g/d), pastries/desserts (+55 g/d), other refined starchy foods (+36 g/d), and snacks/fast foods (+26 g/d) than their 1996 counterparts. In 1996 and 2006, the main source of calories was white rice, whereas in 2017, it was sugary drinks (12% TE and 15% TE, respectively; P < 0.05). The intake ratio of beans to white rice was significantly higher in 1996 (1:1.6) than in 2017 (1:3.5). CONCLUSIONS: The changes in the intake of major nutrients and food sources of Costa Rican adolescents present new public health challenges for cardiometabolic risk prevention. Costa Rica should prioritize the design of comprehensive strategies that target added sugar intake while simultaneously increasing access to and promotion of healthful items.

RESUMO

BACKGROUND: Although mostly food-based, the majority of dietary guidelines also recommend limiting the consumption of foods high in SFAs. Yet, the association between the consumption of SFAs from different food sources and overall diet quality remains uncertain. OBJECTIVES: The objective of this study was to examine the associations between SFAs from various food sources and the 2015 Healthy Eating Index (HEI-2015) as a proxy of overall diet quality. METHODS: The study sample included 11,106 respondents between 19 and 70 y of age from the 2015 Canadian Community Health Survey. Dietary intakes as well as the HEI-2015 were calculated using data from a single 24-h recall. An HEI-2015 from which the SFA subscores were subtracted was also calculated. Low nutritive value foods were defined using Health Canada's 4-Tier system. Associations were investigated using multivariable linear regressions with restricted cubic splines. RESULTS: Major sources of SFAs in this population were low nutritive value foods [4.4% of total energy intake (%E)], dairy (2.7%E), and meat products (1.9%E). The associations between SFA consumption (total and from different food sources) and the HEI-2015 were generally inverse and nonlinear (P for the nonlinearity test <0.03 for all). Total SFA intake showed no association with the SFA-subtracted HEI-2015 (P = 0.29). SFAs from dairy tended to be associated with an increase in the SFA-subtracted HEI-2015 (P < 0.001). Removing the SFA subscore from the HEI-2015 did not materially modify its association with SFAs from meat. SFAs from low nutritive value foods remained significantly and inversely associated with the SFA-subtracted HEI-2015 (P < 0.001). CONCLUSIONS: These cross-sectional data in Canadian adults suggest that intake of SFAs from low nutritive value foods, but not total SFA intake, is captured by an index of healthy eating that does not account for SFA intake.

RESUMO

Objectives. To identify the effect of a Breakfast in the Classroom (BIC) initiative on the foods and drinks students consume in the morning.Methods. Sixteen public schools in Philadelphia, Pennsylvania, that provide universal breakfast participated in a group randomized trial to examine the effects of BIC with complementary nutrition promotion between 2013 and 2016. Control schools (n = 8) offered breakfast in the cafeteria before school. Baseline data were collected from 1362 students in grades 4 to 6. Endpoint data were collected after 2.5 years. Students self-reported the foods and drinks they consumed in the morning.Results. At endpoint, there was no effect of the intervention on breakfast skipping. Nearly 30% of intervention students consumed breakfast foods or drinks from multiple locations, as compared with 21% of control students. A greater proportion of intervention students than control students consumed 100% juice, and a smaller proportion consumed sugar-sweetened beverages and foods high in saturated fat and added sugar.Conclusions. A BIC initiative led to improvements in the types of foods and drinks students consumed in the morning. However, the program did not reduce breakfast skipping and increased the number of locations where students ate.

RESUMO

Most U.S. adults consume too much sodium and not enough potassium (1,2). For apparently healthy U.S. adults aged ≥19 years, guidelines recommend reducing sodium intake that exceeds 2,300 mg/day and consuming at least 3,400 mg/day of potassium for males and at least 2,600 mg/day for females* (1). Reducing population-level sodium intake can reduce blood pressure and prevent cardiovascular diseases, the leading causes of death in the United States (1,3). Adequate potassium intake might offset the hypertensive effects of excessive sodium intake (1). Data from the 2015-2016 What We Eat in America (WWEIA) dietary interview component of the National Health and Nutrition Examination Survey (NHANES)† were analyzed to identify top food categories contributing to sodium and potassium intake for U.S. residents aged ≥1 year. During 2015-2016, 40% of sodium consumed came from the top 10 food categories, which included prepared foods with sodium added (e.g., deli meat sandwiches and pizza). Approximately 43% of potassium consumed was from 10 food categories, which included foods naturally low in sodium (e.g., unflavored milk, fruit, vegetables) and prepared foods. These results can inform efforts to encourage consumption of foods naturally low in sodium, which might have the dual benefit of reducing sodium intake and increasing potassium intake, contributing to cardiovascular disease prevention.

RESUMO

Processed and ultra-processed foods (UPF) consumption has been associated with development of noncommunicable chronic diseases (NCD). This systematic review aims to summarise and discuss evidence of the relationship between food consumption according to degree of food processing and cardiometabolic risk. Data search was conducted in databases as PubMed, Bireme and Science Direct until July 2018. Studies have shown a positive association of UPF consumption with excess body weight, hypertension, dyslipidemia and metabolic syndrome features. However, disparities found in the studies analysed regarding dietary assessment, confounding factors and differences in food classifications makes comparisons between studies difficult. In conclusion, current evidences indicate the need to monitor UPF intake in global population. However, more studies are necessary to interpret better these associations with similar methodologies used in the studies. As well as longitudinal analyses can help to improve comparisons between outcomes and establish cause-effect relationship between UPF intake and cardiometabolic risk.

RESUMO

In 2020, the older adult population ( ≥ 65 years old) reached 703 million worldwide and 3.6 million in Taiwan. By 2026, Taiwan will become a super-aged society with at least 20 percent of the population in this category and 180,000 new older adults joining this population annually. The consequences of oropharyngeal physiological degradation include dysphagia, malnutrition, and a negative impact on quality of life. The provision of texture-modified foods and thickened liquids assist users with chewing or swallowing disorders, making foods easier to ingest and improving diet safety. The classification of texture modified foods allows for consistent communication among health professionals, care providers, and industry partners to improve quality of care for users. This article reviews the four texture-modified food classification systems currently in use internationally. 1. International Standardization Committee for Dysphagia: 22 countries implemented this framework, which was developed by a wide range of professions, including nutrition & dietetics, medicine, speech pathology, occupational therapy, nursing, food science & technology. This framework provides internationally standardized terminology and definitions for texture-modified foods and thickened liquids for persons with dysphagia. 2. Japanese Universal Design Foods: This voluntary standard established by the food industry addresses the physical properties related to the texture of food. The four categories in this standard are distinguished based on the hardness and viscosity of food. The category-based terms and the universal design foods logo are displayed on foods to facilitate consumer selection. 3. The smile care food-The Japanese Ministry of Agriculture, Forestry and Fisheries reclassified nursing care food into the following three categories: (i) Food for people without eating problems but with nutrition supplement needs; (ii) Food for people with problems with swallowing functions; and (iii) Food for people with problems with chewing functions. 4. Eatender, Taiwan senior friendly food. This standard designates four texture specifications: Easy to chew, gum mashable, tongue mashable, no chewing needed. This standard is used to grade the texture of packaged foods that use agricultural food ingredients sourced in Taiwan.

RESUMO

Matam is one of the poorest and most food-insecure regions of Senegal. In the past years, repeated environmental shocks such as drought have limited the access to food and it is unclear whether food insecurity is more a function of food availability (FA) and accessibility at the community level (CL) or more related to FA at the household level (HL). To better understand the FA and food security (FS) situation in this region, in 2018, a cross-sectional study was conducted in 103 households living in four villages. Through focus group discussions and direct observations, data on food available at HL and CL were collected as well as on food affordability and household FS. Overall, between 49 and 64 different foods, mostly from plant source, were identified. Around 75% of households had 0 to 3 foods and 7%, 7 to 10; 64% of all households were severely food insecure. FA at HL and its socioeconomic status were positively associated with household FS whereas FA at the CL was negatively associated. Although food assistance may be required to respond to shocks in the area, investments could be made to improve households` socioeconomic level to enhance their access to food.

RESUMO

Daily food processing has the potential to alter the allergenicity of foods due to modification of the physico-chemical properties of proteins. The degree of such modifications depends on factors such as processing conditions, type of food considered, allergenic content, etc. The impact of daily food processing like boiling, roasting, frying or baking on food allergenicity have been extensively studied. The influence of other thermal treatments such as microwave heating or pressure cooking on allergenicity has also been analyzed. Non-thermal treatment such as peeling impacts on the allergenic content of certain foods such as fruits. In this review, we give an updated overview of the effects of daily processing treatments on the allergenicity of a wide variety of foods. The different variables that contribute to the modification of food allergenicity due to processing are also reviewed and discussed.
