Abstract
BACKGROUND & AIMS Restricted linear growth and abnormal weight status are commonly observed among children in low-income countries, possibly due to inadequate protein intake. Considering the role of protein intake and amino acid (AA) synthesis in growth and development, it has been suggested that there may be an association between AA intake and physical growth. We aimed to investigate the association between different types of AA intake and physical growth among children. METHODS A cross-sectional study including 780 six-year-old children referred to 10 health care centers for vaccination between October 2017 and March 2018 was conducted. Anthropometric data was collected using standard methods, and dietary intake was assessed using a validated food-frequency questionnaire (FFQ) in an interview by a trained technician. RESULTS Children in the highest tertile (3rd) of branched-chain amino acids (BCAA) intake had a higher weight-for-age z-score (WAZ) (P = 0.02) and body mass index-for-age z-score (BAZ) (P = 0.001) compared to those in the lowest tertile (1st). Interestingly, BAZ was significantly associated with the highest tertile of acidic AA intake (P = 0.04), while an inverse association was observed between the highest tertile of aromatic AA (phenylalanine and tyrosine) intake and BAZ (P = 0.01) . No significant associations were observed between the highest tertile of sulfuric, aliphatic, or neutral AA and BAZ, height-for-age z-score (HAZ) or WAZ. Further, underweight was associated with the 3rd tertile of aromatic, alcoholic, aliphatic or neutral AA and BCAA intake. Aliphatic and neutral AA intake was also increased the risk of overweight. Finally, stunted growth patterns were associated with the highest tertile of acidic, alcoholic. CONCLUSION Findings presented in this study showed that higher BAZ and WAZ are associated with 3rd tertiles of BCAA intake, but lower BAZ were associated with 3rd tertiles of aromatic AA (phenylalanine and tyrosine) intake. Future research in other populations are needed to confirm these findings.

Abstract
Dietary recommendations to reduce the consumption of free sugars often group 100% fruit juice with other sugar-containing beverages. The objective of this study was to determine the effect of consuming 100% orange juice compared to an orange drink on next-meal food intake (FI), glycemic response, average appetite, emotions, and sensory characteristics in normal-weight adults. Thirty-six normal-weight adults (age: 26.8 ± 0.9 years) consumed, in random order and at least 5 days apart, three 240 mL test beverages as follows: (a) 100% orange juice, (b) orange drink, or (c) water. Subjective sweetness and pleasantness were determined immediately after test beverage consumption. Glycemic response, average appetite, and subjective emotions were measured every 15 min for 60 min. Food intake was determined at a pizza lunch 60 min later. Rest-of-day glycemic response and energy intake (EI) were determined using a continuous glucose monitor and food record, respectively. Lunch FI (p = 0.054) and total EI (p = 0.01) were both lower after 100% orange juice compared with the orange drink. Caloric compensation was 84% after 100% orange juice and -25% after the orange drink (p = 0.047). Average appetite was not significantly different between the test beverages (p > 0.05). Blood glucose iAUC adjusted for available carbohydrate was lower after 100% orange juice compared with the orange drink (p < 0.001). Rest-of-day blood glucose concentrations were lower after 100% orange juice compared with the orange drink (p = 0.03) and water control (p < 0.001). In conclusion, consumption of 100% orange juice as a preload resulted in higher caloric compensation, lower total daily EI, and lower blood glucose concentrations compared to the orange drink.

Abstract
BACKGROUND & AIMS Weight status and growth during childhood are indicative of healthy development throughout the lifespan. Thus, understanding the influence of overall quality of diet and dietary patterns on anthropometric measures during childhood is critical to inform dietary recommendations. The current study used an updated version of the healthy eating index (HEI) to evaluate the association between overall diet quality and measures of childhood development in six-year-old children. METHODS This cross-sectional study was conducted across 788 six-year-old children referred to healthcare centers in Tehran, Iran. Anthropometric indices and dietary intake were evaluated using standard protocols and food frequency questionnaires, respectively. The HEI-2015 was used to evaluate participant diet quality. The total HEI-2015 score ranged from zero to 100 using the sum of thirteen food score components. RESULTS Children in the highest tertile of HEI score had higher nutrient intakes and HEI-related food groups (p < 0.05). Children within the highest tertile of HEI score compared to those within the lowest tertile were more likely to be overweight (OR: 1.45; 95% CI = 1.01; 2.08). CONCLUSIONS Findings presented in this study showed that HEI was not associated with a greater likelihood of obesity, underweight, severe underweight, and stunting. However, children in the highest tertile of HEI score were more likely to be overweight.

Abstract
Cardiovascular disease (CVD) remains the leading cause of death globally, and epidemiological studies have suggested a link between diet and cardiometabolic risk. Currently, the prevalence of CVD is rapidly increasing with an aging population and continues to contribute to the growing economic and public health burden. However, there is limited evidence available regarding dietary patterns and cardiometabolic risk factors in older adults. We conducted a cross-sectional study to assess dietary patterns and cardiometabolic risk factors in males ≥60 years. Factor analysis identified a "healthy" diet and an "unhealthy" diet as the two primary dietary patterns. Multivariable logistic regression was used for estimating the associations of identified dietary patterns and cardiometabolic risk factors including anthropometric measures, blood pressure, glycemic biomarkers, lipid profile, and inflammatory biomarkers. A healthy dietary pattern was significantly associated with decreased odds of high serum fasting blood sugar (FBS) (OR: 0.32; 95% CI: 0.15-0.67; Ptrend=0.002), but increased odds of high serum low-density lipoprotein cholesterol (LDL-C) (OR: 1.82; 95% CI: 1.02-3.24; Ptrend=0.04). In comparison, an unhealthy diet was associated with increased odds of obesity (OR: 2.33; 95% CI: 1.31-4.15; Ptrend=0.004) and high LDL-C (OR: 2.00; 95% CI: 1.10-2.61; Ptrend=0.02). Thus, in older adults, adherence to an unhealthy dietary pattern has a significant impact on clinically relevant risk factors for cardiometabolic risk.

Abstract
OBJECTIVE Weight status and growth during childhood are indicative of healthy development throughout the lifespan. It is well understood that dietary patterns and overall quality of diet can prevent disease, improve health status and optimise growth and development. The current study investigates the relationship between overall diet quality and measures of childhood development including body mass index and height-for-age in 6-year-old children. METHODS This cross-sectional study was conducted across 788 6-year-old children from Tehran, Iran, in 2018. Food quality score (FQS) was used to assess overall diet quality, in addition to a modified food-based diet quality score specific to children (modified FQS) developed by our group. RESULTS Participants in the highest tertile using the modified FQS had the highest height-for-age z-score (HAZ) (-0.509 ± 0.028 vs -0.605 ± 0.028; P = .048). In contrast, participants in the highest tertile assessed using the original FQS had a higher BMI for age z-score (BAZ) compared to participants in the first tertile (0.391 ± 0.072 vs 0.266 ± 0.072; P = .023). Children within the highest tertile, according to the original FQS, compared to those within the lowest tertile were 49% less likely to be categorised as severely underweight (OR: 0.51; 95% CI: 0.47-0.98). CONCLUSIONS Findings presented in this study demonstrate that FQS was significantly associated with participants characterised as severely underweight; however, FQS was not associated with other anthropometric parameters. Therefore, future well-designed cohort studies are required to address limitations of the current study.

Abstract
Background Previous studies have suggested that choline and betaine are associated with improved anthropometric measures including, BMI and waist circumference however, results are largely inconsistent and limited studies exist in children. Our objective was to investigate the relationship between dietary choline and betaine, and anthropometric measurements among Iranian children. Methods In this cross-sectional study, dietary information was collected for 788 six-year-old children, who attended Tehran health centers in 2018. We measured dietary intakes using a valid and reliable semi-quantitative food frequency questionnaire. The USDA database was used to calculate dietary choline and betaine. We assessed anthropometric characteristics, physical activity, and socio-demographic status based on a reliable and valid protocol. Logistic regression adjusted for energy, physical activity, socio-economic status, and maternal age, physical activity, BMI, and HEI2015 was used to assess this association. Results Free choline, glycero-phospho-choline, phospho-choline, phosphatidyl-choline, total choline, and total betaine, and choline were not related to overweight, obesity, underweight and wasting in the crude and adjusted model after controlling for children’s energy intake, children’s physical activity, socio-economic status, maternal physical activity, and BMI. Betaine intake was associated with mid-arm circumference and risk of overweight. Conclusions We did not find any evidence to support the association between dietary choline with anthropometric measurements among Iranian children. Further prospective studies with a large sample size in different populations are needed.

Abstract
Objective Diet is a fundamental modifiable risk factor for the development of depression and anxiety. However, no evidence currently exists regarding the association of food quality score (FQS) and mental health in Iranian women. This study investigated the relationship between food quality score, depression, anxiety and stress in Iranian women. Results Results showed that 35%, 41% and 42% of participants had depression, anxiety and stress, respectively. The average age of participants was 31.40 ± 7.47 years. A significant association was indicated between FQS and symptoms of depression (OR: 0.36; 95% CI 0.21, 0.63), anxiety (OR: 0.31; 95% CI 0.18, 0.53), and stress (OR: 0.39; 95% CI 0.23, 0.66) in both crude and adjusted models.

Abstract
BACKGROUND AND AIM Although the relationship between a Mediterranean diet (Med diet) and cardiovascular disease (CVD) risk factors has been widely established, no reports exist regarding this association in patients with Diabetes Nephropathy (DN). The aim of this study was to determine the association between level of adherence to a Med diet and renal and CVD risk factors among patients with DN. STUDY DESIGN A cross-sectional study. METHODS The current study was conducted in 270 patients with DN. A validated food frequency questionnaire was used to assess dietary intake. The Med diet score was determined based on the eight characteristics of a traditional Med diet. Anthropometrics, fasting blood glucose (FBS), total cholesterol (TC), low-density lipoproteins (LDL-c), triacylglycerol (TG), hemoglobin A1C (HbA1c), creatinine (Cr) and blood urea nitrogen (BUN) were detected using standard methods. Kidney function was estimated using the Modification of Diet in Renal Disease (MDRD) formula for estimated glomerular filtration rate (eGFR). RESULTS In fully-adjusted models, high serum TC and diastolic blood pressure (DBP) were reduced in participants that demonstrated a greater adherence to a Med diet, but did not reach statistical significance (OR: 0.20; 95% CI: 0.01, 5.52; P = 0.299; OR: 0.81; 95% CI: 0.28, 2.36; P = 0.667). Waist circumference (WC) was non-significantly lower in male participants (OR: 0.91; 95% CI: 0.27, 3.05; P = 0.889). Greater compliance with a Med diet showed a non-significant reduced risk for increased bodyweight (OR: 0.82; 95% CI: 0.23, 2.85; P = 0.730) and obesity (OR: 0.45; 95% CI: 0.03, 6.06; P = 0.493). CONCLUSION Adherence to a Med diet was not significantly associated with cardiovascular risk factors and renal function among patients with Diabetes Nephropathy.

Abstract
Dietary protein affects energy balance by decreasing food intake (FI) and increasing energy expenditure through diet-induced thermogenesis (DIT) in adults. Our objective was to investigate the effects of increasing the dietary protein in an isocaloric breakfast on subjective appetite, FI, blood glucose, and DIT in 9-14 y children. Two randomized repeated measures designs were used. In experiment 1, 17 children (9 boys, 8 girls) consumed isocaloric meals (450 kcal) on four separate mornings containing: 7 g (control), 15 g (low protein, LP), 30 g (medium protein, MP) or 45 g (high protein, HP) of protein. Blood glucose and subjective appetite were measured at baseline and regular intervals for 4 h, and FI was measured at 4 h. In experiment 2, 9 children (6 boys, 3 girls) consumed the control or HP breakfast on two separate mornings, and both DIT and subjective appetite were determined over 5 h. In experiment 1, all dietary protein treatments suppressed subjective appetite compared to control (p < 0.001), and the HP breakfast suppressed FI compared with the LP breakfast and control (p < 0.05). In experiment 2, DIT was higher after HP than control (p < 0.05). In conclusion, increasing the dietary protein content of breakfast had favorable effects on satiety, FI, and DIT in children.

Abstract
Previous studies reported inconsistent findings regarding the consumption of a vegetarian diet with mental health outcomes, specifically depression, anxiety and stress. A systematic review was conducted to summarize the current state of literature regarding our understanding of the association between a vegetarian diet and depression, anxiety and stress. A literature search was completed using Scopus, PubMed, and the Web of Science for relevant articles published prior to July 2020. Prospective cohort and cross-sectional studies conducted on adults reporting risk estimates for the consumption of a vegetarian diet, depression, anxiety, and stress were selected. A fixed effects or a random effects model was performed to pool effect sizes. Results from 13 publications (four cohort studies and nine cross-sectional studies) assessing the relationship between the consumption of a vegetarian diet and depression, anxiety and stress were included. The pooled effect size from 10 studies indicated no association between the consumption of a vegetarian diet and depression (pooled effect size: 1.02, 95% CI: 0.84-1.25, p = 0.817). Further, the pooled effect size from four studies suggests that a vegetarian diet is not associated with anxiety (pooled effect size: 1.09, 95% CI: 0.71-1.68, p = 0.678). Due to insufficient data for stress, we were not able to pool the results. Together, no significant associations were observed between the consumption of a vegetarian diet and depression or anxiety. Future cohort studies are needed to further investigate the effects of a vegetarian diet on these mental health outcomes.

Abstract
Background: Examining dietary approach to stop hypertension (DASH) diet based on other dietary quality indices can be helpful to clarify positive aspects of this healthy dietary pattern. We aimed to examine the association between the DASH diet score and some diet quality indices among Iranian women. Methods: In this cross-sectional study, 304 women aged 20 to 50 years old were recruited. Dietary diversity score (DDS), dietary energy density (DED), adherence to DASH diet, AlternativeHealthy Eating Index (AHEI) and mean adequacy ratio (MAR) were examined as suggested by previous articles. Dietary quality indices, anthropometric indices, and dietary intake were categorized based on DASH tertiles. A semi-quantitative food frequency questionnaire with 168items was used for dietary assessment. Results: There were no significant differences in the demographic characteristics of participants across DASH tertiles (P>0.05). Participants who adhered more to the DASH diet had lower DEDthan those with lower adherence (0.99±0.35 vs 1.26±0.30; P=0.01). Significant differences were observed in the index of DDS across tertiles (P=0.01), however no differences in nutrient adequacy ratio (NAR) and MAR (0.93) index across the DASH categories were found.Additionally, DDS to DED in the top tertile of the DASH diet was greater than the bottom one(6.7±2.9 vs 4.4±1.9; P=0.001). Conclusion: The present study indicated that greater adherence to the DASH diet is inversely associated with DED and AHEI. As well as, there was a positive association between the DASHdiet and DDS/DED ratio. However, more studies are needed to confirm the results of this study

Abstract
Dietary n-6 polyunsaturated fatty acids (PUFA) are widely perceived to promote inflammation and contribute to the development of chronic diseases. This dogma has been recently questioned due to evidence that n-6 PUFA, specifically linoleic acid (LA, 18:2n-6) and arachidonic acid (AA, 20:4n-6), do not appear to activate inflammatory signalling pathways when consumed in moderate amounts. However, delineating the independent roles of different dietary n-6 PUFA in vivo is challenging because LA is continuously converted into AA in a pathway regulated by the fatty acid desaturase 2 (Fads2) gene. The objective of this study was to investigate the independent roles of LA and AA on white adipose tissue (WAT) inflammatory signalling pathways using Fads2-/- mice. We hypothesized that dietary LA would not induce WAT inflammation, unless it was endogenously converted into AA. Male C57BL/6 wild-type (WT) and Fads2-/- mice were fed low-fat isocaloric diets containing either 7% corn oil w/w (CD, containing ~42% LA) or 7% ARASCO oil w/w (AD, containing ~27% AA) for 9 weeks. WAT inflammatory gene expression, protein levels, as well as phospholipid (PL) and triacylglycerol (TAG) fatty acid composition, were analyzed by RT-qPCR, western blots, and gas chromatography, respectively. Fads2-/- mice fed CD had high LA, but little-to-no GLA (18:3n-6), DGLA (20:3n-6), and AA in PLs and TAGs compared to their WT counterparts. In comparison, Fads2-/- and WT mice fed AD showed minimal differences in n-6 PUFA content in serum and WAT, despite having significantly more AA than CD-fed mice. No differences in gene expression for common inflammatory adipokines (e.g. Mcp-1, Ccl5, Tnfα) or key regulators of eicosanoid production (e.g. Cox-2, Alox-12, Alox-15) were detected in WAT between any of the diet and genotype groups. Furthermore, no differences in MCP-1, and total or phosphorylated STAT3 and p38 inflammatory proteins, were observed. Collectively, these results demonstrate that neither LA nor AA promote WAT inflammation when consumed as part of a low-fat diet. Therefore, the existing dogma surrounding n-6 PUFA and inflammation needs to be reconsidered.

Abstract
White adipose tissue (WAT) has a critical role in lipid handling. Previous work demonstrated that SCD1 is an important regulator of WAT fatty acid (FA) composition; however, its influence on the various interconnected pathways influencing WAT lipid handling remains unclear. Our objective was to investigate the role of SCD1 on WAT lipid handling using Scd1 knockout (KO) mice and SCD1-inhibited 3T3-L1 adipocytes by measuring gene, protein, and metabolite markers related to FA reesterification, glyceroneogenesis, and lipolysis. Triacylglycerol (TAG) content was higher in inguinal WAT (iWAT) from KO mice compared with wild-type, but significantly lower in epididymal WAT (eWAT). The SCD1 desaturation index was decreased in both WAT depots in KO mice. FA reesterification, as measured with a NEFA:glycerol ratio, was reduced in both WAT depots in KO mice, as well as SCD1-inhibited 3T3-L1 adipocytes. Pck1, Atgl, and Hsl gene expression was reduced in both WAT depots of KO mice, while Pck2 and Pdk4 gene expression showed depot-specific regulation. Pck1, Atgl, and Hsl gene expression was reduced, and phosphoenolpyruvate carboxykinase protein content was ablated, in SCD1-inhibited adipocytes. Our data provide evidence that SCD1 has a broad impact on WAT lipid handling by altering TAG composition in a depot-specific manner, reducing FA reesterification, and regulating markers of lipolysis and glyceroneogenesis.
