Dietary malpractice is a risk factor for obesity. This study tested the hypothesis that consumption of a high-fat diet alters mammary metabolome in pubertal mice. We performed untargeted metabolomic analysis of primary metabolism on mammary glands from pubertal mice fed the AIN93G standard diet or a high-fat diet (HFD) for 3 weeks. We identified 97 metabolites for statistical comparisons. The HFD altered the amino acid metabolism considerably. This included elevated expression of branched-chain amino acids, non-essential amino acids (aspartic acid and glutamic acid), and methionine sulfoxide (oxidized methionine) and an alteration in the aminoacyl-tRNA biosynthesis pathway. Furthermore, elevations of fumaric acid and malic acid (both are citrate cycle intermediates) and glyceric acid (its phosphate derivatives are intermediates of glycolysis) in HFD-fed mice suggest an acceleration of both citrate cycle and glycolysis. Lower expression of glycerol, oleic acid, and palmitoleic acid, as well as decreased mammary expression of genes encoding lipid metabolism (Acaca, Fads1, Fasn, Scd1, and Srebf1) in HFD-fed mice indicate an attenuated lipid metabolism in the presence of adequate dietary fat. In conclusion, consumption of the HFD for 3 weeks alters metabolic profile of pubertal mammary glands. This alteration may affect mammary development and growth in pubertal mice.

Objective: The aim of our study was to assess the association of eating habits with the dietary patterns of people with diabetes.

Methods: This cross-sectional study was conducted at National Institute of Diabetes and Endocrinology (NIDE), Dow University Hospital in Karachi, Pakistan. A total 301 patients aged >18 with type 2 diabetes came to Outpatient department were recruited. Structured questionnaire was used to assess general characteristics, Anthropometric measurements, biochemical markers, and dietary intake.

Results: A total of 301 patients with type 2 diabetes mellitus were included in this study. The average age of patients was 51.6 (SD ± 11.1) years which ranged from 21 to 80 years whereas the average BMI was 27.2 kg / m² (SD ± 5.6). Overall, 42% of patients were found to often have less than 1 serving of fruit, and 45% had less than 3 servings of vegetables daily. Of all, 77 (26%) patients often distributed carbohydrates all over the day. Results revealed that HbA1c was higher in those patients who took more than 3 roti (approximately each roti weight 60-80 g) (P-value < .001) and full plate rice approximately 300 to 355 g cooked weight in a whole day (P-value < .001) as compared to those patients whose intake of roti was 3 or less than 3 and rice was a half plate. Moreover, out of 301 patients, 102 were found physically active (52% females and 48% males), while 199 were not active. Pain in legs and lack of motivation were common barrier to physical activity.

Conclusion: Our study revealed that patients' fruits and vegetable intake was not optimum, diet was not balanced and the quantity of starchy carbohydrates was not controlled which may affect their HBA1C levels. Proper counseling and awareness about the importance of a balanced diet and portion control in diabetes are needed.

Background: Sleep quality is defined as an individual's consent to sleep experience. Poor sleep quality has important adverse health outcomes. There are drugs to treat sleep disorders but consumption of these drugs is accompanied by adverse effects whereas herbal treatments have fewer side effects. Saffron is spice obtained from Crocus sativus flower. Several articles have been done on its effects on the quality of sleep and its safety. This review for the first time critically evaluates effect of saffron on sleep quality improvement.

Method: The search technique aims to get all related published data-based up to 2022 articles. PubMed, Central, Google Scholar, and Scopus were examined. Only full reports were evaluated (abstracts were excluded). The first screening was done by title and abstract. Then full text of articles was read and irrelevant articles were removed. Duplicate articles were also removed by Endnote. By using Cochrane risk of bias tool assessment, a quality score based on probability of bias was given. Methodological characteristics were also evaluated using the criteria of Stevinson and Ernst.

Result: In the systematic review, 5 randomized clinical trials with 379 participants from 3 countries were identified. In placebo-comparison trials, saffron contains a large treatment.

Conclusion: It seems that saffron has a beneficial influence on duration and quality of sleep. Saffron, crocin, and safranal induce hypnotic effects by increasing the duration of sleep. Research conducted so far provides initial support and safety for use of saffron to improve sleep quality.

Objective: To measure changes in micronutrient adequacy and diet quality in healthcare and university employees who underwent a 10-week teaching kitchen program.

Methods: Thirty-eight healthcare and university employees participated in a 10-week teaching kitchen program. Twenty-seven completed self-administered, 24-hour dietary recalls to measure dietary intake at baseline and 3-months. Micronutrient adequacy and diet quality was assessed using Dietary Reference Intakes (DRIs) and the Healthy Eating Index (HEI).

Results: Seventy percent of participants were classified as low or moderate micronutrient adequacy at baseline. The proportion of participants with high micronutrient adequacy increased from 30% to 48% at 3-month follow-up. Total HEI and most HEI components increased at follow-up; with a statistically significant increase in seafood/plant protein score (P = .007).

Conclusions and implications for practice: Our results suggest an inadequacy in micronutrient intake in university and healthcare employees and that teaching kitchens may help improve micronutrient adequacy and diet quality.

Background: The rapid biological and physical changes during adolescence require adequate nutrient intake. This study assessed dietary diversity and nutritional status of adolescents living in selected rural areas in Ghana.

Method: In this cross-sectional study, 137 young adolescents, aged 10 to 14 years were recruited. Structured questionnaire was used to collect data on sociodemographic, household size and food intake practices. A multiple past 24-hour recall was used to estimate the micronutrients intake. Haemoglobin and anthropometry data were assessed. Dietary diversity score was assessed with 10 food groups described by Food and Agricultural Organization. Descriptive, chi-square, binary regression and partial correlation were used in the data analysis.

Results: The prevalence of underweight was 5.5%, overweight 5.8% and anaemia 29.9%. The mean dietary diversity score was 3.8 ± 0.8 and about 84.7% of participants had inadequate dietary diversity. Proportions of adolescents who consumed from the different food groups over a 24-hour period were: grains, white roots and tubers, plantain (100%); pulses (10.2%); nuts and seeds (34.1%); dairy (8%); meat, poultry and fish (86.9%); eggs (7.3%); dark green leafy vegetables (29.9%); other vitamin-A rich fruits and vegetables (2.2%); other vegetables (81%); other fruits (7.3%). Dietary diversity scores were positively and significantly correlated with intake of micronutrient, with correlation coefficients of .169, .186, .191, .173 and .175 for vitamin A, niacin, vitamin B₆, iron and zinc, respectively. Meal skipping (AOR = 12.2, P < .001, 95% CI: 3.6-41.7) and snacking (AOR = 5.0, P = .007, 95% CI:1.6-16.7) increased odds of inadequate dietary diversity.

Conclusion: The high prevalence of inadequate dietary diversity was positively related to meal skipping and snacking among adolescents. Dietary diversity score was significantly related to the intake of vitamin A, niacin, vitamin B₆, iron and zinc. The prevalence of anaemia among our study participants is of public health concern. Adolescents should be encouraged both at home and school to eat from diverse food groups to promote adequate intake of micronutrients.

Background: Milk contains essential nutrients that help can improve the growth and development of adolescent girls.

Objectives: The study determined the effect of milk consumption on the nutritional status of schoolgirls ages 10 to 12 years old in Magdalena, Laguna, Philippines.

Methodology: A quasi-experimental study design was used to determine the impact of daily consumption of 200 ml buffalo milk on the prevalence of undernutrition among the 57 schoolgirl participants before and after 160 days. One sample t-test and paired t-test were used to compare the actual and expected total increment and monthly changes in the height and body mass index (BMI) of the participants, while a one-way analysis of variance was used to compare the actual total changes in height and BMI by age. Factors that are correlated with these measurements were identified based on Spearman's correlation coefficients.

Results: The percentage of stunting (31.6%-22.8%) and thinness (21.1%-15.8%) decreased after the milk feeding. Significant differences were observed in the means of total actual and expected changes in height (P < .00) and BMI (P < .00). While there were significant differences in the means of actual and expected monthly changes in height every month, this was only observed in the first 2 months for BMI. Only the mean actual changes in height had significant differences when compared by age (P = .04). Lastly, the age and education of the father were found to be correlated with the height of the schoolgirls.

Conclusion: Buffalo milk consumption can improve the growth outcomes of schoolgirls.

Background: Malnutrition affects millions of people in developing countries and contributes to poor health outcomes and nutritional status among women in the postpartum period. Lactation increases high nutritional demands and marks a significant life transition that can impact diet quality and subsequently predispose woman to high risk of overweight and undernutrition. Although, studies have been conducted on the nutritional status of lactating women, there is a gap especially on women's nutritional status during the postpartum period. Therefore, this study aimed to assess the nutritional status of postpartum women and associated factors in Shey-Bench District, Bench-Sheko Zone, Southwest Ethiopia, 2020.

Method: A community-based cross-sectional study was conducted in Shey-Bench District from March 1 to 30/2020 among 359 postpartum mothers. Bivariate analysis was employed to select candidate variables at P-value <.25 as a cut-off point. Multiple multinomial logistic regression analysis was used to identify variables significantly associated with nutritional status of the mother at P < .05 with 95% CI.

Results: The study revealed that 10.3% of women were underweight and 16.7% were overweight. Employed mothers (AOR = 4.467, 95% CI [1.05-19.04]), employed husband (AOR = 0.087, 95% CI [0.021-0.370]), farmer husband (AOR = 0.084, 95% CI [0.024-0.293]), trader husband (AOR = 0.19, 95% CI [0.0614-0.616]), married mother (AOR = 0.222, 95% CI [0.088-0.560]), dietary diversity (AOR = 0.181, 95% CI [0.075-0.436]) were significantly associated with underweight and while being overweight was associated with dietary diversity, maternal age of between 15 to 24 and 25 to 34, exclusive breastfeeding, and frequency of breastfeeding.

Conclusion: This study found a lower prevalence of underweight compared with overweight in the study area. Occupational status, marital status, age of the mother, dietary diversity, exclusive and frequency of breastfeeding were significantly associated factors with nutritional status of postpartum mother. We recommend strengthening the provision of nutrition education on modifiable factors with collaboration of other sectors.

Chronic heavy alcohol exposure causes steatohepatitis manifested by abnormal intra-hepatocyte accumulation of lipid and parenchymal inflammation. Attendant alterations in polyunsaturated fatty acid (PUFA)-containing phospholipids could cause alcoholic liver disease (ALD) to progress by promoting oxidative stress, inflammation, and fibrogenesis. Previously we showed that myriocin, a serine palmitoyltransferase inhibitor, ameliorates experimental alcohol-induced steatohepatitis. However, the surprising overall therapeutic responses suggested that myriocin's targets may go beyond sphingolipids. To this end, the present study examines the effects of myriocin on hepatic composition of docosahexaenoic acid (DHA)- and arachidonic acid (AA)-containing phospholipids in an experimental model of ALD. A chronic+binge ethanol exposure model was generated by feeding Long Evans rats with ethanol-containing diets (24% caloric content) for 8 weeks and simultaneously binge gavage administering 2 g/kg ethanol on Tuesdays, Thursdays and Saturdays during Weeks 6-8. Myriocin was administered by i.p. injection on Mondays, Wednesdays, and Fridays of Weeks 3-8. Control rats were studied in parallel. Upon euthanasia, the livers were harvested to examine ethanol- and/or myriocin-modulation of hepatic lipids using matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS). Results were analyzed statistically by two-way analysis of variance and depicted with data bar plots and heatmaps. Chronic+binge ethanol exposures significantly increased hepatic expression of AA-containing phospholipids including PE(36:4) (P = .005), PE(38:4) (P = .03), and PI(38:4) (P = .04) and reduced DHA-containing phospholipids including PS(40:6) (P = .03) and PE(40:6) (P = .04) relative to control. Myriocin partially reversed ethanol's effects on hepatic PUFA expression by decreasing PE(36:4) (P = .004) and increasing PS(40:6) (P = .04) and PI(40:6) (P = .0003) relative to ethanol-exposed rats. Ethanol-mediated alterations in hepatic PUFA-containing phospholipids may contribute to hepatic oxidative and inflammatory injury by increasing AA and fibrogenesis by inhibiting DHA. The results suggest that Myriocin may help reduce or prevent long-term and progressive liver injury stemming from excessive chronic+binge ethanol consumption.
