Purpose The purpose of this study was to examine sensory attributes, physiochemical characteristics and consumer preference of drop sugar cookies prepared using high-amylose maize resistant starch (HAMRS) as a replacement for 10%, 20% and 30% of all-purpose (AP) flour as compared to a control made with 100% AP flour. Design/methodology/approach A balanced complete block experimental design was used to evaluate the eating quality of the resistant starch enriched cookies using a consumer panel. Consumer preference for the appearance, flavor, texture, moistness and overall acceptability of cookies was assessed. Diameter, height, spread ratio, hardness, moisture, pH, density, surface color and nutrient composition of cookies were analyzed. Findings Compared with the control cookies, the HAMRS cookies had lower diameters, higher, heights, reduced spreads, reduced % moisture losses and lower densities (p < 0.001). TA.XT Plus Texture Analyzer showed the HAMRS cookies had a softer texture than the control cookies (p < 0.0001). Evaluation of surface color showed no significant difference in lightness between the control and the HAMRS cookies. The HAMRS cookies were preferred over the control for appearance, texture and moistness in sensory evaluation with 42.5% of panelists choosing the 20% HAMRS replaced cookies as their overall preference. The 20% and 30% HAMRS replaced cookies qualify to be labeled as a “good source” and “excellent source” of fiber, respectively. Practical implications This data demonstrates that replacement of up to 30% of AP flour with HAMRS improves eating quality and dietary fiber content of sugar cookies. Our results show that HAMRS has good potential for developing high fiber cookies with minimal adverse impact on physical characteristics and notable improvements in sensory attributes and nutritional value. Originality/value To the best of the authors’ knowledge, this is the first study that has reported on the functionality, consumer preference and nutritional value of cookies enriched with a HAMRS that is available to consumers in the form of flour.

Purpose Life conditions for most slum dwellers are deplorable, with poor socio-economic status and high rates of malnutrition and communicable diseases. Studies have shown lower intake of many nutrients in such people, but no study yet has checked the quality of diet using Healthy Eating Index (HEI) in them. This study aims to assess the quality of diet among slum dwellers of Tehran using the HEI-2015. Design/methodology/approach This cross-sectional study was conducted among 300 slum dwellers from two slums located on the border of Tehran city which is the capital of Iran. Stratified random sampling technique was used to select subjects for this study. Data on socioeconomic characteristics and 24-hours dietary recalls were obtained through face-to-face interviews with the respondents by trained personnel. Findings The overall diet quality of the respondents was poor, with a mean HEI score of 40.9 ± 23.7. About 84% of the participants had low overall HEI scores. A significant relation was seen in the following: the HEI and educational level (p = 0.044); the HEI and employment status (p = 0.001); and the HEI and chronic diseases (p = 0.049). There was no significant difference between the mean HEI score and marital status, welfare status and addiction status. From the findings, the diet of most of these slum dwellers needs modification. Therefore, taking measures to reduce slum dwelling and to improve the nutritional intake of this study population is needed. Originality/value The study was approved by the Ethics Committee of Tehran University of Medical Sciences, Tehran, Iran, and written informed consent was obtained from all participants.

Purpose The purpose of this paper is to evaluate the levels of food safety knowledge, attitudes and practices (KAP) of consumer. Design/methodology/approach In total, 1,161 volunteers were included in this study, which has been developed to measure the knowledge, attitudes and behaviors of adults on food safety. Study data were collected through an online survey technique. Findings A statistically significant difference was determined between male and female participants and also at the education level considering total food safety attitude and practice scores (p < 0,001). It was determined that university graduates had higher scores at all scales than the median scores. When an assessment was made on the body mass index of the participants, it was seen that the implementation and attitude scales were statistically different from each other, and in paired comparisons on these scales, the average scores of normal-weight individuals were observed higher in the sub-dimensions than slightly obese individuals (p < 0.007; p < 0.001). Research limitations/implications Even though the population of the study was adults living in different cities, the results should not be generalized to all adults and the whole country. Also, the fact that the answers to the questions were not face-to-face, could create a bias. Although the reliability coefficient was found to be high, the data reported by the individuals participating in the study about their behavior formed the study results. Originality/value This study makes an important contribution to the literature. Determining the knowledge, attitude and behavior of consumers about food safety is important in ensuring food safety.

Purpose Recently, evidences have suggested that healthy eating index (HEI), an index-based dietary pattern, may be a predictor for the risk of cancer. This paper aims to examine the association of HEI-2015 and its all components scores with the risk of breast cancer (BC), separately, among Iranian women. Design/methodology/approach In the present hospital-based, case-control study, 150 age-matched of cases (newly diagnosed female) and 150 controls were recruited. Data of dietary habits and anthropometric measures were obtained, and eventually, the HEI-2015 score was calculated. Multivariate odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the relationship between the risk of BC across tertiles (Ts) of total HEI-2015 and its all component scores. Findings The results presented that in adjusted model, there was no significant difference between total HEI-2015 (p = 0.14) and its all component scores (p > 0.09) of healthy subjects and females with BC. Moreover, multivariable logistic regression analyses indicated that HEI-2015 score was not associated with the risk of BC in either crude (p-trend = 0.94) or adjusted (p-trend = 0.73) analyses. In the analyses of HEI-2015 components scores, it was observed that the scores of grains (OR, 0.53; 95% CI, 0.30–0.94) and total protein foods (OR, 0.13; 95% CI, 0.02–0.58) may have a relation with BC risk in crude model but after adjusting for BC risk factors, the mentioned associations changed to non-significant. Originality/value The findings of current study suggested that there was no significant association of total HEI-2015 and its components scores, independently, with BC incidence among Iranian women.

Purpose This study aims at determining the risk of physical inactivity and sedentary behaviors on overweight and obesity among primary school children aged 10–13 years in Tanzania. Design/methodology/approach A case-control study was conducted from January to March 2020 involving 69 overweight/obese children as cases and 138 normal weight children as controls. Cases were identified as having body mass index-for-age ≥ +1 standard deviation (SD) and controls as those having BMI-for-age range between −2 SD to <+1 SD. A validated questionnaire was used for data collection on daily physical activities and sedentary behavior types, frequency duration and activity score. An independent sample t-test was used to compare means of activity score between cases and controls. Binary logistic regression was used to predict risk factors for overweight/obesity. Findings Risk factors for overweight/obesity were listening to music and/or radio for >2 h/week (OR 2.7, 95% CI 1.2–6.1) and walking for exercise <2 h/week (OR 2.1, 95% confidence interval [CI] 1.1–4.1). On the other hand, rope skipping for >2 h/week (OR 0.14, 95% CI 0.03–0.7) was a protective factor against overweight/obesity. Controls had a significantly higher mean score of being active during lunch breaks compared to cases (p = 0.012). Cases had higher weight, height and percentage body fat than controls (p < 0.001). The home environment provided more avenues for physical activity than the school environment. Originality/value To the best of the authors’ knowledge, this is original research work and the first case-control study to predict physical activity and sedentary behaviors as risk factors for overweight and obesity in Tanzanian school children.

Purpose This paper aims to depict the mechanistic role of vitamin D on dementia prevention, relief of the severity and the complication of the disease. All papers indexed in scientific databases, including Scopus, Elsevier, PubMed, Embase and Google Scholar between 2000 and 2021 were extracted and discussed. To present the mechanistic role of vitamin D in declining the severity of dementia, keywords including dementia, vitamin D, oxidative stress, inflammation, amyloid beta-Peptides were used. Design/methodology/approach Dementia is a prevalent cognitive disorder worldwide, especially in elderly people, which is accompanied by serious disabilities. Besides genetic, biological and lifestyle factors are involved in the incidence of dementia. An unhealthy diet along with micronutrient deficiencies are among modifiable factors. Vitamin D is one of the important micronutrients in brain health. Besides the involvement in gene expression, bone mineralization, apoptosis, inflammation, skeletal maturation, neurotropic action and hemostasis of phosphate and calcium, vitamin D also exerts neuroprotective effects via genomic and non-genomic pathways. Findings Vitamin D up-regulates the expression of various genes involved in dementia incidence via various mechanisms. Decreasing oxidative stress and the neuro-inflammatory cytokines levels, regulation of the expression of alternated Proteins including Tau and Amyloid-ß, calcium homeostasis in the central nervous system and also vascular are considered main mechanisms. Originality/value Considering the importance of diet in preventing dementia, adherence to a healthy diet that provides essential nutrients to brain function seems to be urgent. Controlling serum levels of vitamin D periodically and providing vitamin D by related sources or supplements, if there is a deficiency, is recommended. Future studies are needed to clarify other related mechanisms.

Purpose This study paper aims to evaluate the Phytochemical Composition, anti-obesity, anti-antipyretic and analgesic effect of Ephedra alata (Ea) extracts. Design/methodology/approach Obesity was induced in male Wistar rats through a high-fat/fructose diet (HF/FD). Control rats received a standard diet. Findings Results of this study showed that the Ea methanol extract (MEEa) exhibited a prominent selective inhibitory effect against lipase activity (IC50 = 1.29 mg/ml) as compared to water and ethyl acetate extracts (with IC50 = 1.63 and 1.89, respectively). Also, MEEa exert antipyretic and analgesic activities. In high-fat-high-fructose diet rats, the administration of MEEa inhibited lipase activity in the intestine, pancreas and serum by 53%, 40% and 53%, respectively. It was found to significantly decrease body weight by 20% (p = 0.09) and delay the absorption of triglycerides (TG), total cholesterol (TC), LDL-cholesterol (LDL-C) and increase HDL-cholesterol (HDL-C). In addition, MEEa efficiently decreased a-amylase activity in the intestine, pancreas and serum by 43%, 26% and 46%, respectively, and blood glucose level by 35% (p = 0.06). Originality/value To the best of the authors’ knowledge, this study demonstrates for the first time that MEEa are efficient in preventing obesity and hyperglycemia, pain and fever.

Purpose It is well accepted that diabetes is associated with heart diseases and hyperlipidemia as a risk factor. In traditional medicines, some herbs such as Aloe vera seem to be effective in controlling diabetes. Owing to lack of human studies, this study aims to examine the effect of Aloe vera consumption on fasting blood sugar (FBS), lipid profiles and body composition in type 2 diabetic patients. Design/methodology/approach This double-blind, placebo-controlled trial study was conducted in 2019, in Shiraz, Iran. A total of 56 diabetic subjects were randomized by block randomization to receive a daily supplement of 1,000 mg Aloe vera powder capsules (n = 28) or placebo (n = 28) for eight weeks. At baseline and after eight weeks of treatment, dietary intake and physical activity were assessed by three-day food recall and international physical activity questionnaire. Meanwhile, after an overnight fasting, FBS and lipid profiles were measured. Blood pressure and anthropometric parameters were assessed in the beginning and the end of the study. Independent t-tests were used for between-group analysis and paired t-tests for within-group analysis. Findings After intervention, weight, body mass index and waist circumference significantly decreased in comparison to the placebo group (p-value: < 0.001, 0.001 and 0.02). Although, FBS, total triglyceride and systolic blood pressure decreased significantly (p-value: 0.03, 0.001 and 0.01), no change has been seen in low density lipoprotein, high density lipoprotein and total cholesterol blood level and diastolic blood pressure. Research limitations/implications The limitations of this study are the short study duration and lack of Aloe vera powder’s ingredient analysis. Originality/value This study is one of few human studies investigating the effect of Aloe vera on metabolic syndrome’s indices in diabetic patients. Because pharmacological therapy is tough, not comfort and correlated with potential adverse drug interactions, it is important to find an alternative or complementary measure to aid the diabetic patients. This study shows that Aloe vera has positive effect on body weight and blood sugar.

Purpose This paper aims to determine the eating habits and physical activity in students of the Rafael Núñez University. Design/methodology/approach Descriptive cross-sectional study, based on the application of a survey on eating habits and physical activity. Furthermore, height, weight, hip circumference and abdominal circumference were also recorded. Findings Total, 170 students were included, 29 (17.1%) males and 141 (82.9%) females, with a mean age of 20.0 ± 5.2 years. Among the students, 22 (12.9%) were underweight, 95 (55.9%) were normal weight, 40 (23.5%) were overweight and 13 (7.7%) with obesity. Regarding eating habits, the majority preferred to consume three daily meals: breakfast 140 (82.3%), lunch 170 (100%) and dinner 96 (56.5%). Regarding fruits intake, 18 (15.9%) males reported consuming them seven days a week, and 54 (31.2 %) females reported consuming them occasionally. In physical activity, most of the population (n = 103, 60.6%) exercises with a frequency of one to three days/week. Originality/value The authors’ work is original and has not been sent to another magazine.

Purpose Stunting, which refers to low height-for-age, is one of the most important public health problems in Ethiopia, and it more accurately reflects nutritional deficiencies and illness that occur during the most critical periods for growth and development in early life. Given this, this paper aims at determining the magnitude and factors associated with stunting among 6–59 month old children in Ilubabor Zone, Southwest Ethiopia. Design/methodology/approach This paper opted for a descriptive study using an interviewer-administered questionnaire and anthropometric measurements of 617 children aged 6–59 months. A systematic random sampling technique was used to select the study participants. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 25 and World Health Organization (WHO) Anthro software. Multivariate logistic regression analysis was used to identify independent predictors of stunting. Findings About 33.7% of children aged 6–59 months included in this study were stunted. The proportion of moderate and severe stunting among the stunted children was 26.4% and 7.3%, respectively. Large family size (AOR = 4.0; 95% confidence interval [CI]: 2.5, 6.4), low dietary diversity score (AOR = 7.8; 95% CI: 4.6, 13.0) and household food insecurity (AOR = 16.4; 95% CI: 10.0, 26.7) were independent predictors of stunting. Research limitations/implications Reporting and recall bias related to food groups consumed over the past seven days and seasonal variation may affect the findings related to factors associated with stunting. Practical implications Globally, it is estimated that nearly 165 million children under the age of five are stunted. Outcomes associated with stunting include increased risk of mortality, increased disease risk, developmental delays, diminished ability to learn and lower school achievement and reduced lifelong productivity. So, determining the level of stunting in a particular community is important to design strategies for curbing the contributing factors. Originality/value This study’s community-based design yields a representative sample of study subjects in the Hurumu district, which is valuable for intervention methods and actions. Standardized tools that are validated for use by the World Health Organization are used. Besides, anthropometric data were analyzed using the updated WHO Anthro software.
