Adolescents' use of online food delivery applications and perceptions of healthy food options and food safety: a cross-sectional study in the United Arab Emirates.

Introduction: This cross-sectional study aimed to assess Online food delivery applications (OFDA) usage trends among adolescent users in the United Arab Emirates (UAE), focusing on their perceptions of healthy food options and food safety (n = 532). Methods: Sociodemographic information, frequency of OFDA use, factors affecting food choices, and perceptions of healthy food and food safety were investigated. A total perception score was calculated for each participant. Results: Most participants used OFDAs weekly (65.4%), favoring fast food (85.7%). Factors like appearance and price drove food choices (65.0%), while taste and cost hindered healthy food orders (29.7 and 28.2%). Younger and frequent users had lower scores for perceiving healthy food, while seeking healthy options was associated with higher scores (p < 0.05). Females and those seeking healthy food showed higher food safety scores (p < 0.05). Discussion: The study suggests tailored interventions to promote healthier choices and improve food safety perceptions among adolescents using OFDAs in the UAE.

Pertinence of Salt-Related Knowledge and Reported Behaviour on Salt Intake in Adults: A Cross-Sectional Study.

The association between salt-related knowledge, attitude, behaviour (KAB) and actual salt consumption in Greek adults is uncertain. This study investigates the correlation between salt intake, gauged by 24-h urinary sodium excretion, with salt-related KAB. It further explores how socio-demographic factors influence these behaviors. Salt consumption was evaluated using a 24-h urinary sodium test, and compared to self-reported KAB data. Knowledge and behavior scores related to salt were computed. An overall cohort-adjusted model examined the relationship between daily salt consumption, knowledge and behavior scores, and certain covariates. Through the stratification by the cohort random effect, two models were established (Cohort I Adults; Cohort II Students) examining the same relationships of the overall cohort model. 463 Greek adults participated. The average salt intake was 9.54 g/day, nearly double the WHO recommendation. Significant differences in knowledge scores were noted based on sex, age, education, and BMI. A trend suggesting lower discretionary salt use with increased salt intake was observed (p = 0.06). However, comprehensive analysis revealed no direct correlation between salt intake and either knowledge (p = 0.562) or behavior scores (p = 0.210). The results emphasize the need for food product reforms by industry stakeholders and accelerated efforts towards reducing salt intake.

The impact of ultra-processed foods on obesity and cardiometabolic comorbidities in children and adolescents: a systematic review.

CONTEXT: Over the past few decades, traditional foods have been displaced by ultra-processed foods (UPFs), with the latter being associated with health problems. OBJECTIVE: This scoping systematic review aimed to identify the relationship between UPF intake and overweight/obesity as well as other cardiometabolic risk factors during childhood and adolescence. DATA SOURCES: The guidance for this protocol is the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P). A systematic search was undertaken on PubMed, Scopus, and Cochrane Library electronic databases based on prespecified inclusion and exclusion criteria up to 6 February 2022. DATA EXTRACTION: A total of 17 observational studies-9 cross-sectional, 7 cohort-longitudinal, and 1 study reporting both cross-sectional and longitudinal outcomes-among children and adolescents aged ≤18 years were eligible for inclusion in this review. Fourteen studies evaluated the consumption of UPFs in association with overweight/obesity and 9 studies examined the association of UPF consumption and cardiometabolic-related risk factors. DATA ANALYSIS: Most studies (14/17) showed that an increase in UPFs was associated with a higher prevalence of overweight/obesity and cardiometabolic comorbidities among children and adolescents, whereas 4 of 17 studies (3 cross-sectional and 1 cohort) found no association. Most cohort and cross-sectional studies showed good quality according to the National Institutes of Health and Newcastle-Ottawa quality assessment, respectively. CONCLUSION: The positive association found between UPFs and overweight/obesity and cardiometabolic comorbidities among children and adolescents raises concerns for future health. Further investigation is recommended to explore the role of specific types of UPFs on cardiometabolic conditions and to identify the amount of daily intake that increase risk in order to shape appropriate public health policies.

Changes of trans and saturated fatty acid content in savory baked goods from 2015 to 2021 and their effect on consumers' intake using substitution models: A study conducted in Greece.

BACKGROUND: In Greece, nearly a third of savory baked goods (SBGs) exceeded the limit of 2 g of nonruminant or industrial trans fatty acids (i-TFA) per 100 g fat in 2015. The impact of the Commission Regulation (European Union) 2019/649 on exposure to trans fatty acids (TFA), i-TFA, and saturated fatty acid (SFA) from SBGs has not been previously evaluated. OBJECTIVES: The study aimed to explore fatty acid reformulation of SBG products and assess differences in TFA, i-TFA, and SFA intakes using a sample of Greek SBG consumers from a nationally representative survey. METHODS: In 2021, 140 samples of SBGs were collected in the greater metropolitan area of Athens, and their fat profile and content were compared to those from 2015. Based on these measurements, food consumption substitution models were employed to examine TFA and SFA intake differences, and the percent contribution from SBG among consumers was calculated (N = 1008). Nutrient densities were calculated by adjusting all fat intakes by individual mean energy intake (percentage of daily total energy intake). RESULTS: The 2% i-TFA legislative limit/100 g of fat in measured SBGs was exceeded by 11.4% in 2021 compared to 31.1% in 2015 (19.7% increase in compliance). Median i-TFA and TFA intakes from SBGs were reduced from 0.05 (0.01, 0.12)% and 0.13 (0.03, 0.27)% in 2015 to 0.03 (0.01, 0.09) and 0.06 (0.03, 0.13)% in 2021, respectively. In terms of SFA, a mean increase/100 g was calculated, resulting in an increased intake in 2021 compared to 2015 [5.18% (2.78, 8.37) and 3.55 (1.99, 5.73), respectively]. CONCLUSIONS: Despite the reductions seen in i-TFA content of SBGs, food product reformulation efforts in Greece should focus not only on TFA content but also on SFA reduction to improve public health.

Assessing Health Care Providers' Knowledge and Practices of Nutrition during Pregnancy in Lebanon: A Cross-Sectional Study.

Background and objectives: Health care professionals (HCPs) are well-positioned to discuss healthy behaviors during pregnancy, but the published research of prenatal healthcare providers' knowledge about the significance of nutrition during pregnancy in Lebanon is scarce. The purpose of this study was to explore the knowledge, attitudes, and practices of Lebanese prenatal healthcare providers towards nutrition during pregnancy. Materials and Methods: A cross-sectional study using an online questionnaire was conducted. Health care providers were contacted by phone and email to participate in the online survey. A list of all clinics providing antenatal health services was obtained from the Order of Physicians and the Order of Midwives. A multistage random sample was selected. In the first stage, it was stratified per region (Beirut center or suburbs, and the southern region). In the second phase, it was stratified per clinic type (private, primary healthcare center, or hospital). Gynecologists and midwives who are members of the Order of Physicians and the Order of Midwives (n = 1333), were included. Results: Two-hundred and six responses (55% males) were obtained. Approximately 44% of the HCP were aged 50 and older, and 68.4% had more than 10 years of work experience. HCPs from Beirut represented 41.3% of the respondents. Eighty-eight percent of the HCPs were physicians, and 11% were midwives. The majority of the participants considered nutrition during pregnancy to be very important. Furthermore, half of these participants considered their position in delivering nutrition information as very significant. Most of the respondents reported that they provide nutrition advice to pregnant women, and they also received nutrition education during their profession. However, they perceived their nutrition knowledge as inadequate. Conclusion: Health care providers' attitude towards the importance of maternal nutrition and their confidence in talking about nutrition-related topics with pregnant women were positive despite the lack of knowledge in several areas related to nutrition during pregnancy. Therefore, there is a need for continuing nutrition education for health care providers and the implementation of nutrition education programs to achieve better health outcomes.

Association of fructose consumption with prevalence of functional gastrointestinal disorders manifestations: results from Hellenic National Nutrition and Health Survey (HNNHS).

The study aimed to assess the total prevalence of functional gastrointestinal disorders (FGID), and separately, irritable bowel syndrome (IBS) among adults and to determine their potential association with fructose consumption. Data from the Hellenic National Nutrition and Health Survey were included (3798 adults; 58·9 % females). Information regarding FGID symptomatology was assessed using self-reported physician diagnosis questionnaires the reliability of which were screened using the ROME III, in a sample of the population. Fructose intake was estimated from 24 h recalls, and the MedDiet score was used to assess adherence to the Mediterranean diet. The prevalence of FGID symptomatology was 20·2 %, while 8·2 % had IBS (representing 40·2 % of total FGID). The likelihood of FGID was 28 % higher (95 %CI: 1·03-1·6) and of IBS 49 % (95 %CI: 1·08-2·05) in individuals with higher fructose intake than with lower intake (3rd tertile compared with 1st). When area of residence was accounted for, individuals residing in the Greek islands had a significantly lower probability of FGID and IBS compared with those residing in Mainland and the main Metropolitan areas, with Islanders also achieving a higher MedDiet score and lower added sugar intake, comparatively to inhabitants of the main metropolitan areas. FGID and IBS symptomatology was most prominent among individuals with higher fructose consumption, and this was most conspicuous in areas with a lower Mediterranean diet adherence, suggesting that the dietary source of fructose rather than total fructose should be examined in relation to FGID.

Nitrite and nitrate intake from processed meat is associated with elevated diastolic blood pressure (DBP).

BACKGROUND AND AIMS: Processed meat consumption has been linked to high blood pressure (BP), a key risk factor for cardiovascular disease (CVD), but gaps remain with regards to the ingredients which contribute to this association. This study, therefore, aimed to examine the association between nitrite and nitrate intake from processed meat with diastolic (DBP) and systolic (SBP) blood pressure, while accounting for sodium intake. METHODS: Dietary nitrite and nitrate intake from processed meat, assessed as total nitrite equivalent, was estimated for 1774 adult, processed meat consumers (≥18 years, 55.1% females) who had enrolled in the Hellenic National Nutrition and Health Survey (HNNHS). To avoid selection and reverse causality bias, associations with measured DBP and SBP were considered instead of self-reported data of hypertension presence. Participants were divided by tertile of dietary nitrite intake and by level of dietary guideline adherence for sodium (<1500; 1500-2300; ≥2300). Multiple regression models were used to examine associations with SBP and DBP, including an interaction term of nitrite with dietary sodium intake, for potential synergy. RESULTS: Overall, DBP increased by 3.05 mmHg (95% CI: 0, 6.06), per tertile increase in nitrite intake and 4.41 mmHg (95% CI: 0.17, 8.64) per level increase in sodium intake, when the interaction effect between nitrite and total sodium intakes was accounted for. By considering the significant synergistic effect of the two factors, DBP finally increased by 0.94 mgHg overall and 2.24 mgHg for subjects in the third tertile compared to those in the first. Also, a rise in total sodium intake of approximately 800 mg, above 1500 mg, caused a 2.30 mgHg increase in DBP. No significant correlations were found with SBP. CONCLUSIONS: Higher nitrite and nitrate intake from processed meats contributed to the increase of DBP, but the interaction effect with total sodium intake levels should be accounted for to properly interpret the findings.

Short-Term Effects of Spirulina Consumption on Glycemic Responses and Blood Pressure in Healthy Young Adults: Results from Two Randomized Clinical Trials.

The effects of spirulina consumption added in foods were investigated in two crossover clinical trials (n = 13 different healthy adults). In Trial-1 adults consumed cookies with-and-without spirulina (3.12 g per 100 g final product; 2.5 g spirulina per 50 g available carbohydrates) according to glycemic index (GI) methodology. In Trial-2, adults consumed 4 g, 6 g, and 8 g spirulina as beverage diluted in 50 g D-glucose vs. 50 g plain D-glucose. Capillary blood glucose samples were collected at 0, 15, 30, 45, 60, 90, and 120 min and blood pressure (BP) was measured at beginning and end of each visit in both trials. Trial-1: both cookies with and without spirulina provided medium GI values (59 and 60, respectively, on glucose-scale), but no significant differences were found for BP. Trial-2: both 4 g and 8 g spirulina lowered postprandial glucose at 120 min (95% CI: -1.64 to -16.12 and -1.23 to -15.87, respectively). The results explained 29% of variation. Only 8 g spirulina decreased significantly 90-120 min area under the curve (AUC) for glucose and systolic BP (-4%). No differences were found for fasting glucose. Adding spirulina to cookies did not affect glucose responses and BP. Only 8 g provided significantly lower 90-120 min-AUC for glucose and BP compared to 4 g, 6 g-and-D-glucose, indicating advantages to glycemic control and hypertension.

Factors Associated with Breastfeeding Initiation and Duration in Greece: Data from the Hellenic National Nutrition and Health Survey.

Despite its well-documented benefits, breastfeeding rates and duration worldwide do not meet the recommended goals set by the World Health Organization. Data on infant feeding, socio-demographic, lifestyle and perinatal factors were used from 490 mothers (and 958 children), participants at the Hellenic National Nutrition and Health Survey between 2013−2015. Clustered multiple logistic regression and multilevel mixed-model regression analyses were performed to identify factors associated with breastfeeding initiation and duration, respectively. Maternal lower education [Odds Ratio (OR): 2.29, 95% Confidence intervals (95% CI): 1.30−4.04; p = 0.004], smoking during pregnancy (OR: 3.08, 95% CI: 1.64−5.77; p < 0.001), caesarean section (OR = 3.26, 95% CI: 1.83−5.83; p < 0.001), prematurity (OR = 2.74, 95% CI: 1.40−5.37; p = 0.003) and higher birth order (OR = 1.30, 95% CI: 1.04−1.62; p = 0.020) were associated with increased odds of not initiating breastfeeding. Living in rural areas [beta coefficient b = −27.93, p = 0.043], smoking during pregnancy (b = −64.47, p < 0.001), caesarean section (b = −28.76, p = 0.046) and prematurity (b = −46.67, p = 0.048) were significantly associated with shorter breastfeeding duration. Children born chronologically closer to the survey were more likely to breastfeed and for longer periods. Educational promotion and enhancement of breastfeeding awareness that account for maternal exposures are required. Prevention of prematurity and avoidance of unnecessary caesarean section is crucial, while additional breastfeeding support is needed when preterm birth occurs, or caesarean section cannot be avoided.

Risk Assessment of Nitrite and Nitrate Intake from Processed Meat Products: Results from the Hellenic National Nutrition and Health Survey (HNNHS).

Long-term exposure to a high nitrite and nitrate intake through processed meat is of concern, as it has been related to adverse health effects. Individual consumption data from 2152 participants (46.7% males) in the Hellenic National Nutrition and Health Survey (HNNHS) were linked with current Maximum Permitted Levels (MPLs) to calculate exposure to nitrite and nitrate from processed meat products (assessed as nitrite equivalent), evaluate potential risk and identify the major contributors. Processed meat intakes were determined by combining data from 24 h recalls and frequency of consumption reported in Food Propensity Questionnaires (FPQs). Median exposure was estimated to be within safe levels for all population groups. However, 6.6% (n = 143) of the consumers exceeded the Acceptable Daily Intake (ADI) of nitrite (0.07 mg/kg bw/day), of which 20.3% were children aged 0-9 years (N = 29) (15.3% of all children participants in the study, N = 190). In total, pork meat was the major contributor (41.5%), followed by turkey meat (32.7%) and sausages (23.8%), although contribution variations were found among age groups. The outcomes are of public health concern, especially exposure among children, and future research is warranted to evaluate possible associations with health effects, by using more refined occurrence data if available.

The Association of Sugar-Sweetened Beverages to Children's Weights Status Is Moderated by Frequency of Adding Sugars and Sleep Hours.

Adding extra sugars in milk and the moderating effect of sleep has yet to be investigated, setting the aim of this study. A total of 1361 school-aged children were included, aged 10−12 years old, by randomly sampling schools. Data were interview-obtained by trained personnel using a validated 17-item food frequency questionnaire, with specifics on type of milk and extra sugar additions. Analyses were stratified by average recommended hours of sleep. Predictive probability margins were obtained following necessary adjustments. Mean BMI was significantly lower, the level of SSB intake was higher, and the prevalence of adding sugars to milk four or more times per week was higher in children that slept ≥10 h. Most children (64%) consumed full fat milk, 21% had low fat, and 19.7% chocolate milk, with a significantly larger proportion of overweight or obese children consuming full fat or chocolate milk, also adding extra sugars four or more times per week (4.1% compared to 9.6%, and 12.2% compared to 39.5%, respectively). The predictive probability of being overweight or obese exponentially increased for children consuming >0.5 SSB/day while also adding sugars to their milk frequently, although this effect remained significant only for children sleeping <10 h/day. In conclusion, to accurately address the effect of SSBs on children's body weight, frequency of any type of sugar addition in milk should be accounted for, as well as average sleep hours that may further moderate the effect.

Dietary nitrate and nitrite and human health: a narrative review by intake source.

Nitrate and nitrite are plant nutrients that, although ubiquitous in plant foods, are highly controversial substances in human nutrition because they are also used as additives in processed foods and may be found as contaminants in drinking water. The aim for this narrative review is to provide a thorough insight into the current literature on the relationship between dietary nitrate and nitrite and the health risks and benefits by source of intake. The results highlight beneficial effects of nitrate and nitrite consumption from plant origin on cardiovascular disease and, to date, no positive correlation has been reported with cancer. On the contrary, high intake of these compounds from processed animal-based foods is related to an increased risk of gastro-intestinal cancer. Nitrate in drinking water also raises some concern, because it appears to be related to adverse health effects. The up-to-date debate on the role of nitrate and nitrite in human nutrition seems to be justified and more research is required to verify safe consumption.

The Impact of Nutritional and Lifestyle Changes on Body Weight, Body Composition and Cardiometabolic Risk Factors in Children and Adolescents during the Pandemic of COVID-19: A Systematic Review.

The coronavirus (COVID-19) pandemic and the measures taken by most countries to curb virus transmission, such as social distancing, distance learning, population, home confinement and disruption of all organized activities, has affected children and adolescents worldwide. The aim of this review was to assess the role of diet and lifestyle changes due to COVID-19 measures on body weight/composition and cardiometabolic risk factors in children and adolescents. An electronic search was conducted in PUBMED, COCHRANE, Google Scholar and SCOPUS databases up to 31 October 2021. 15 eligible studies were identified. According to the studies included in the analysis, COVID-19 measures seem to have had a negative impact on the diets and lifestyles of children and adolescents, with a consequent increase in body weight and central fat accumulation. On the other hand, the parental presence and control resulted in better glycaemic control in children with diabetes mellitus (DM) Type 1, but the effect of the pandemic in the glycaemic control of children with DM2 2 is controversial. Finally, diet and lifestyle changes had a differential impact on children's hypertension prevalence. These findings point to the need for public policy measures to prevent obesity and its complications, to and improve diet and lifestyle during the continuing and yet unresolved COVID-19 epidemic.
