Water Nutriture: Essential but Misunderstood
Authors: Pratyusha Vavilala and Nandita NarayanasamyIn their search for life, space scientists are looking for traces of water on other planets in the solar system because of the well accepted knowledge that water is important for all living systems. Water makes up 60-75% of human body weight. A loss of just 4% of total body water can lead to severe dehydration, and a loss of 15% is fatal. What makes water so essential for survival? Though life on earth is described as a carbon-based phenomenon, it would not be amiss to also call it a water-based phenomenon, as water is the universal solvent that dissolves all biological molecules. Despite this deep understanding of both the chemistry and the biochemical importance of water in human physiology, questions still remain regarding what is the required consumption of water? What type of water is to be ingested? In the context of Nutrition, water is not only an essential nutrient but is also an important source of antinutrients and toxins. Another question that remains ambiguous is: How much water is essential? If it is a nutrient, does it have an RDA? Can one suffer and die from water intoxication? This review puts together in simple terms what one needs to know about water as an essential nutrient in our diet.

Plant-Derived Proteins/Peptides for the Management of Alzheimer's Disease
Authors: Rishabha Malviya and Prerna UniyalAlzheimer's Disease (AD) is a neurological condition that worsens over time and has a gradual start. It has a significant impact on the well-being of human beings. Peptides are substances produced from plants that have been revealed to inhibit the progression of Alzheimer's disease disorders, making them a promising strategy for the prevention of Alzheimer's disease. Nevertheless, because of the enormously convoluted pathophysiology of Alzheimer's Disease (AD) and the recognition that the majority of research on the action of plant-derived peptides is solitary instead of sufficiently comprehensive, the development and implementation of Plant-derived Alzheimer-prevention Peptides (PADPs) have been constrained. The molecular pathways of PADPs, AD-prevention activity, and some perspectives on current advanced technologies have been discussed in this review. Additionally, the review provides a summary of the current techniques available for obtaining PADPs, as well as in vitro and in vivo protocols for evaluating the activity of PADPs in preventing Alzheimer's disease. Additionally, the fundamental concepts for the manufacturing and utilization of PADPs have been developed in this study.

Benefits of Bambara Groundnut (Vigna subterranea) as a Source of Protein on Reproductive Function Related to Ghrelin-leptin in Female Mice Fed a Low Protein Diet
Authors: Rimonta Febby Gunanegara, Agung Dewanto and SunartiBackgroundLow protein intake during pregnancy increases maternal mortality and blood levels of leptin and ghrelin, the hormones that regulate energy balance, affecting energy intake and body weight. The benefits of protein depend on the amount and type of amino acids that make up the protein. The need for L-lysine amino acids in pregnant women is reported to increase, especially at the end of pregnancy. Bambara beans contain high levels of the amino acid L-lysine, so they can be used as a source of protein that contains high levels of L-lysine.
ObjectiveThis study evaluated the Bambara groundnuts (Vigna subterranea) supplementation effects on reproductive function related to ghrelin-leptin in female mice fed a low protein diet.
MethodsQuasi-experimental study with a control group employing 50 female mice divided into five groups: normal protein diet (N), low protein diet (LP), low protein diet with 100 g (LP+100); 200 g (LP+200), and 300 g (LP+300) Bambara groundnut supplementation. After 2 months of intervention, half of the mice in each group (n=25) were terminated, and blood samples were collected to determine albumin, ghrelin, and leptin levels. The other half mice were mated to assess gestational age.
ResultsSupplementation with Bambara groundnuts at 200 and 300 g/kg of feed increases protein intake and ghrelin and leptin levels. The leptin/ ghrelin ratio in the group of mice supplemented with Bambara groundnut at a dose of 300 g/kg feed shows a similar ratio to the normal group. Although there were no significant changes in albumin levels in all groups, protein intake, ghrelin and leptin levels were positively correlated with gestational age.
ConclusionBambara groundnuts can reduce the negative effect of a low protein diet in female mice. It is an excellent protein source that increases the leptin/ghrelin ratio to improve gestational age.

Fuzzy Modeling to Personalized Nutritional Menu
BackgroundWhile most healthy diets can help control the progression of disease, they can fail in the long term for many factors. Patients abandon the diet altogether after a while because it is too restrictive or the foods are unappealing; still, others engage in less physical activity because they consume fewer calories. What's more, almost all plans are based on optimization models. These models produce statistical diets offering limited choices to users, and a small substitution can call the whole diet into question.
ObjectiveThis article develops an intelligent system for generating flexible nutritional menus that each person can adopt to their environment and dietary preferences (food availability, price, patient eating habits, etc.). The system implements mathematical fuzzy optimization models and constraint satisfaction programming.
Methods and MaterialsFirst, the Moroccon foods were decomposed using fuzzy Cmeans. Next, the artificial foods, formed by the centers, were introduced into a fuzzy mathematical optimization diet model, which controlled the total glycemic load and met the World Health Organization (WHO) and Dietary Guidelines for Americans (GDA) recommendations (requirements for personalized menu). Then, we used a genetic algorithm strategy to generate optimal serving sizes and to build a nutritional menu based on the groups formed. To help patients choose customized diets, the menu was transformed into a constraint satisfaction programming model.
ResultsThe proposed strategy was applied to Moroccan foods, experimental results show that all diets offer a wide range of choices to users and that substitutions comply with WHO and GDA recommendations.
ConclusionThe suggested scheme has been applied to Moroccan foods; experimental findings demonstrate that all diets provide users with a wide variety of options that keeps consumers on their diet.

Optimization and Characterization of a Nanostructured Lipid Carrier Containing α-Tocopherol/Tocotrienol Prepared using Rice Bran Oil and Palm Kernel Stearin
Authors: Putri Masitha Silviandari, Sri Raharjo and Arima Diah SetiowatiBackgroundα-tocopherol and tocotrienol are known for their antioxidant properties and cannot be produced directly in the human body. However, their use remains limited because of their low solubility, instability, and susceptibility to oxidation and high temperatures.
ObjectiveThis study aims to identify the optimal formulation of a carrier of phytonutrient α-tocopherol/tocotrienol prepared via ultrasonication with rice bran oil (RBO), palm kernel stearin (PKS), and Tween 80 and determine the characteristics of the optimal formulation during storage.
MethodsThe box-behnken design (three factors and levels) was used to determine the formulation of a nanostructured lipid carrier -tocopherol/tocotrienol (NLC-TT) based on the solid: liquid lipid ratio, total lipid: surfactant ratio, and sonication time.
ResultsThe optimal NLC-TT formulation prepared with a solid: liquid lipid ratio of 7.5:2.5, total lipid: surfactant ratio of 1:3.9, and sonication time of 12 min and 6 s yielded a particle size of 126.7 nm, a polydispersity index of 0.339, a zeta potential of -31.7 and an encapsulation efficiency (EE) of 96.4%. During storage, NLC-TT and NLC-free particles exhibited particle sizes of 123.6-144.2 nm, polydispersity indices of 0.245-0.339, zeta potentials of -31.7--39.6 mV, EEs of 96.4%-89.6%, stabilities of 2.02-1.63, peroxide values of 0.05-0.25 mEqO2/kg, anisidine values of 0.07-1.60 and free fatty acid contents of 0.04%-0.08%.
ConclusionRBO and PKS are potential lipid-based carrier systems for tocopherol/ tocotrienol and exhibit good stability during storage.

Prevalence and Pattern of Dietary Supplement Use in Bodybuilding Athletes
IntroductionUsing sports supplements is a common strategy for improving athletic performance. The prevalence of using sports supplements among adolescent and young athletes has been increasing in recent years.
MethodsThis descriptive-analytical study was performed on 200 bodybuilding athletes. The data collection tool was a pre-made questionnaire. The questionnaire was distributed among the athletes by available methods and collected after filling out. The chi-square test, Fisher's exact test, and logistic regression model were used to analyze the data.
ResultsThe prevalence of using sports supplements was 62.5% (n=125), with males accounting for 67.5% (n=135) of the consumers. Various forms of proteins (43.5%, n=87), vitamins (40.5%, n=81), and hormones (38.5%, n=77) were the most commonly recommended supplements by the coaches (58.4%, n=73) and other athletes (31.2%, n=9). The sports supplements have been considered to have no side effects by 16.8% (n=21) of the athletes; however, 19.2% (n=24) mentioned cardiac adverse events, and 13.6% (n=17) pointed to renal complications as potential consequences of supplement use. The results of statistical tests and a logistic regression model showed a statistically significant relationship between sex, age, education and income, and sports supplement use (p=0.001).
ConclusionAccording to the results of this current study, a significant proportion of bodybuilding athletes take sports supplements without being aware of the side effects. Therefore, it is necessary to develop an educational program to inform the population about the mechanism of action of supplements in the body and also educate athletes and coaches about the correct use, side effects, and irreversible consequences of improper supplements use.

A Survey of the Relationship Between Dietary Quality and Metabolic Syndrome
More LessBackgroundDietary intake is increasingly recognized as a pivotal factor in the etiology of metabolic syndrome. A substantial body of evidence suggests a discernible correlation between dietary quality indices and the occurrence of metabolic syndrome.
ObjectiveThis survey seeks to rigorously evaluate the impact of diet quality indices and demographic variables on the manifestation of metabolic syndrome.
Materials and MethodsThis case-control study encompassed 175 individuals diagnosed with metabolic syndrome and an equal number of age-matched healthy counterparts (Comprising both genders) aged between 20 and 65 years. Participants were sourced from diverse laboratories and the general population in Chalous, northern Iran. Dietary intake data were meticulously acquired using a comprehensive Food Frequency Questionnaire (FFQ). Furthermore, dietary quality indices, specifically the Healthy Eating Index (HEI), Dietary Diversity Score (DDS), Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR), were meticulously evaluated employing standardized methodologies.
ResultsThere was no significant diversity in the likelihood of developing metabolic syndrome concerning the Healthy Eating Index (HEI), Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR) when comparing quartile 4 (Maximum score) to quartile 1 (Minimum score). However, this likelihood diminished following adjustments for confounding variables, including age, sex, dietary energy, education, job, and marital status. In the case of the Dietary Diversity Score (DDS), there was an observed difference in morbidity likelihood between quartile 4 and quartile 1. Nevertheless, after meticulous adjustment for confounding variables, this difference failed to reach statistical significance. No substantial variations (P ≥ 0.05) were detected in the odds ratio across quartiles and models (P trend) for all dietary quality indices.
ConclusionNo significant associations were identified between dietary quality indices and the occurrence of metabolic syndrome.

Relationship between Dietary Diversity Score and Dietary Total Antioxidant Capacity with some Cardio-Metabolic Risk Factors and Pro-Oxidant-Antioxidant Balance in Overweight and Obese Postmenopausal Women
Authors: Aida Malek Mahdavi, Zahra Tofighi, Maryam Rafraf, Tohid Jafari-Koshki and Elham ElhamiBackgroundConsidering the significance of relation between dietary diversity and dietary antioxidants in the mechanism of obesity and related outcomes and due to limited studies in postmenopausal women, the present research was designed to evaluate the relationship between Dietary Diversity Score (DDS) and Dietary Total Antioxidant Capacity (DTAC) with some cardio-metabolic risk factors and Pro-Oxidant-Antioxidant Balance (PAB) level in overweight and/or obese postmenopausal women.
MethodsThe research participants comprised 128 overweight and/or obese postmenopausal women aged 45-65 years attending the health centers. Anthropometric measures, e.g., weight, height, waist and hip circumferences, were obtained. Serum lipid profile, glucose, and insulin were determined, and the Homeostasis Model Insulin Resistance (HOMA-IR) was estimated. PAB was determined. DDS and DTAC were determined using information from the Food Frequency Questionnaire (FFQ).
ResultsCompared to those in the first tertile, there was no significant relationship between anthropometric and biochemical data with DDS neither among participants in the second tertile nor the third tertile (P>0.05). Furthermore, considerable negative relationships were only observed between waist-to-hip ratio (P=0.035) and waist-to-height ratio (P=0.006) with DTAC among participants in the second tertile compared with those in the first tertile. Also, insulin and HOMA-IR were inversely related to DTAC among participants in the second tertile (both P<0.001) and the third tertile (P=0.004 and P=0.009, respectively) compared to those in the first tertile. There was a considerable negative relationship between PAB and DTAC (P=0.036) among participants in the third tertile compared with those in the first tertile.
ConclusionDDS was not correlated with a lower risk of obesity, abdominal adiposity, and better metabolic features. Furthermore, this study demonstrated that higher DTAC was correlated with lower abdominal obesity, insulin, HOMA-IR, and PAB levels.

Authors: Azka Fatima, Sajid Rehman Randhawa and Iqra Hamid KhanBackgroundThe use of probiotics is increasing with time. However, there is limited data available related to the referral and knowledge of pediatricians regarding the use of probiotics.
ObjectivesThe objective of this study is to assess the knowledge, attitudes, and practices of pediatricians toward the referral of probiotics in government hospitals located in Faisalabad, Pakistan.
MethodsA cross-sectional study was conducted on 196 pediatricians who participated in this study. A well-structured, self-administered questionnaire was distributed among participants to assess their knowledge, attitude, and practices towards probiotics referral. The questionnaire was based on four sections including questions related to socio-demographics, knowledge, attitude, and practices about probiotics’ use and referral. The obtained data was analyzed using descriptive statistics and, the chi-square test in SPSS.
ResultsThe findings indicated that the majority of participants had fair knowledge (57.7%), a positive attitude (69.4%), and good practices (80.1%) towards the referral of probiotics products. The chi-square test results revealed that the gender difference of participants was significantly associated with the knowledge (p-value = 0.042). Whereas, the knowledge of participants did not vary significantly concerning the increase in the working experience (p-value = 0.075). In addition, the attitudes and practices of pediatricians were also found to be non-significantly related to the gender difference and working experience of the participants. Furthermore, a significant correlation was found between the attitude and practices (p-value = 0.019), and between knowledge and practices (p-value = 0.000). Whereas, no significant correlation was found between knowledge and attitude (p-value = 0.197).
ConclusionIn conclusion, the majority of the participants in this study had fair knowledge, a positive attitude, and good practices towards the referral of probiotics. Although there are certain limitations to this study, it is the first study that provides insights into the knowledge, attitudes, and practices of pediatricians in Faisalabad, Pakistan. Consequently, it is suggested that additional training programs and healthcare policies should be initiated to further promote the clinical applications of probiotics by enhancing the knowledge of pediatricians as well as other healthcare professionals in the country.
