Requirements for essential micronutrients during caloric restriction and fasting.

Caloric restriction (CR) or energy restriction, when carefully designed, monitored, and implemented in self-motivated and compliant individuals, proves to be a viable non-pharmacologic strategy for human weight control and obesity management. Beyond its role in weight management, CR has the potential to impede responses involved not only in the pathogenesis of various diseases but also in the aging process in adults, thereby being proposed to promote a healthier and longer life. The core objective of implementing caloric restriction is to establish a balance between energy intake and expenditure, typically involving a reduction in intake and an increase in expenditure-a negative balance at least initially. It may transition toward and maintain a more desired equilibrium over time. However, it is essential to note that CR may lead to a proportional reduction in micronutrient intake unless corresponding supplementation is provided. Historical human case reports on CR have consistently maintained adequate intakes (AI) or recommended dietary allowances (RDA) for essential micronutrients, including vitamins and minerals. Similarly, longevity studies involving non-human primates have upheld micronutrient consumption levels comparable to control groups or baseline measures. Recent randomized controlled trials (RCTs) have also endorsed daily supplementation of multivitamins and minerals to meet micronutrient needs. However, aside from these human case reports, limited human trials, and primate experiments, there remains a notable gap in human research specifically addressing precise micronutrient requirements during CR. While adhering to AI or RDA for minerals and vitamins appears sensible in the current practice, it's important to recognize that these guidelines are formulated for generally healthy populations under standard circumstances. The adequacy of these guidelines in the setting of prolonged and profound negative energy balance remains unclear. From perspectives of evidence-based medicine and precision nutrition, this field necessitates comprehensive exploration to uncover the intricacies of absorption, utilization, and metabolism and the requirement of each hydrophilic and lipophilic vitamin and mineral during these special periods. Such investigations are crucial to determine whether existing daily dietary recommendations for micronutrients are quantitatively inadequate, excessive, or appropriate when energy balance remains negative over extended durations.

Nutritional quality and microbial diversity of Chhurpe from different milk sources: an ethnic fermented food of high-altitude regions of the Western Himalayas

Chhurpe is a naturally fermented traditional dairy food of high altitude Western Himalayan region. They are generally prepared from cow or yak milk and are consumed during harsh winters. The present study was conducted to characterize the different Chhurpe samples traditionally prepared by the ethnic groups utilizing milk from different animal breeds such as cow, yak, Zomo (cow × yak), and Germo (Zomo × yak). Nutritional characterization revealed that 100 g of Chhurpe could completely meet the dietary protein requirements of children and adults with high concentrations of methionine and lysine. Tryptophan and valine were the limiting amino acids among all the Chhurpe samples. Palmitic, stearic, and oleic acids were the predominant fatty acids. The Chhurpe samples were a rich source of micronutrients such as calcium, iron, and zinc meeting above 70% of recommended dietary allowances (RDA) among children (3–10 years) and up to 20% RDA for adults. Culture-independent metagenomic analysis revealed that lactic acid bacteria were the predominant group, consisting of genera such as Lactobacillus, Leuconostoc, Lactococcus, and Streptococcus followed by acetic acid bacteria, mainly Acetobacter. At the species level, Lactobacillus delbrueckii was the abundant strain among all the Chhurpe samples. Species diversity was significantly higher in Chhurpe prepared from Zomo milk. Probiotic bacterial strains such as Lactobacillus helveticus, L. delbrueckii, L. brevis, and Leuconostoc mesenteroides were identified in the Zomo Chhurpe indicating their superior quality. The present study was an attempt to popularize Chhurpe and promote its wider consumption by highlighting its nutritional properties.

Морские водоросли как важный функциональный ингредиент и продовольственное сырье для обогащения рационов питания населения Арктической зоны Российской Федерации (обзор)

The paper analysed scientific literature on seaweed as an additional source of nutrients and biologically active compounds. The studies demonstratе that brown algae are promising raw materials for human nutrition. Algae contain 7 amino acids essential for adults, as well as monoiodotyrosine and diiodotyrosine, which induce a hormone-like effect of algae proteins on the human body. Brown algae fats are represented by both saturated and unsaturated fatty acids, which allows us to assume that algae can become an alternative source of essential long-chain polyunsaturated fatty acids, having a positive effect on the cardiovascular and nervous systems, as well as on the cognitive development of children. It should be emphasized that brown algae are a source of fucosterol, which has hypocholesterolemic, hypotensive, antioxidant, anti-inflammatory, antitumour and antidiabetic effects. Algae carbohydrates include polysaccharides unique in their chemical structure and biological activity: alginates, having anti-inflammatory, antioxidant and immunomodulatory properties; fucoidans, producing antibacterial, antioxidant and antitumour effects; and laminarins, exerting immunomodulatory, antioxidant, antitumour and antibacterial effects. Polyphenols contained in algae are not found in terrestrial plants. Algae are a source of iodine and other minerals as well as vitamins. Currently, algae are being used in human diets in a number of countries. However, there are certain problems that require further research, such as the possible side-effects of excessive consumption of seaweed, its daily intake recommendations, and bioavailability of nutrients after seaweed handling and processing. In general, it can be concluded that seaweed may well become an important functional ingredient and alimentary raw material for enriching the diet of the population in the Arctic zone of the Russian Federation.

The results of the study proved that the milk of the Sumbawa wild horse was effective as an anti-bacterial against Staphylococcus epidermidis (one of the bacteria that causes acne). The results of the study, the content of Vitamin C horse clay mask is 64.8% which corresponds to the daily requirement of vitamin C commonly known as the RDA (Recommended dietary allowance) of vitamin C which is 60 mg or the equivalent of an orange, for anti-oxidant activity IC50 10.88 ppm contained in the horsegenic mask able to reduce aging and other skin diseases caused by a lack of nutrient intake for the skin.

Assessment of trace elements (Cu, Fe, and Zn) in Limnothrissa miodon from Lake Kariba, Zambia: implications for ecological and human health

ABSTRACT This study examined Copper (Cu), Iron (Fe), and Zinc (Zn) levels in Limnothrissa miodon fish from Lake Kariba in Zambia and their potential impact on human health. Two-gram samples from each stratum underwent a 12-hour digestion, and concentrations were determined using Microwave Plasma Atomic Emission Spectrometer. Results indicated that Cu, Fe, and Zn concentrations fell within Food and Agricultural Organization and World Health Organization safety limits. Estimated Daily Intake (EDI) and Hazard Quotient (THQ) values for males and females remained under recommended thresholds, suggesting minimal health risks from consumption. Element concentrations followed the order Fe > Zn > Cu, all below Recommended Daily Allowances (RDAs). THQ values, with Zn posing the highest potential risk followed by Fe and Cu, were under one. Overall, the Hazard Index (HI) was 0.02, signifying a low non-carcinogenic risk from fish consumption. Despite safety, ongoing monitoring of heavy metal accumulation in the ecosystem is advisable for long-term safety. In conclusion, trace element levels in Limnothrissa miodon from Lake Kariba are safe for human consumption with low associated health risks. Nonetheless, continued monitoring of heavy metal levels is vital.

Cross-Sectional Study of the Anthropometric Profile and Nutrient Status of Elite Female Ice Hockey Players: Differences by Play Position.

Both the characteristics of ice hockey and the environmental conditions in which it is played affect the maintenance of the player's nutritional status and, therefore, their state of health and performance. The primary aim of this work was to examine the anthropometric profile, estimated energy expenditure, and macronutrient and micronutrient dietary intake of elite female ice hockey players by play position. As a secondary aim, their dietary intakes were compared with the recommendations. Hypotheses suggest variations in body composition based on ice hockey players' positions, with the expectation that these athletes may not align with energy and nutrient recommendations. Fifteen elite female ice hockey players were anthropometrically measured, basal metabolic rate and total energy expenditure were estimated, a 3-day, 24 h recall questionnaire was registered, and the results were compared with the recommended dietary intake for the Spanish population. Each player's position on the field requires an individualized physical and nutritional approach. There are no significant imbalances (p > 0.05) between energy and nutrient intake in relation to the Recommended Daily Intake (RDI); however, increasing the consumption of vegetables and seafood while reducing meat and fat intake would assist these athletes in maintaining a healthier energy balance, optimizing body composition, and aligning with nutritional parameters that are better suited to enhance physical performance.

Elemental composition and evaluation of noncarcinogenic risks of bee pollen from different Turkish areas.

Bee pollen is a complex compound formed by the honey bee through a mixture pollen, nectar, and bee saliva. It contains many elements that have importance for the human biochemical process. However, when the content of minerals in the pollen exceeds the biological limit, it can be toxic to health. This study aimed to assess and identify the presence of 16 essential (potassium [K], phosphorus [P], calcium [Ca], magnesium [Mg], sodium [Na], iron [Fe], silicon [Si], manganese [Mn], zinc [Zn], boron [B], copper [Cu], molybdenum [Mo], nickel [Ni], chromium [Cr], selenium [Se], and cobalt [Co]) and 16 nonessential elements (aluminum [Al], beryllium [Be], barium [Ba], arsenic [As], cadmium [Cd], mercury [Hg], thallium [Tl], lithium [Li], antimony [Sb], vanadium [V], lead [Pb], rubidium [Rb], strontium [Sr], cesium [Cs], titanium [Ti], and uranium [U]) in bee pollen samples from different floral sources in Turkey, while also evaluating the noncarcinogenic risks associated with bee pollen. A melissopalynological investigation was conducted to identify the plant origins of the bee pollen samples. Thereafter, the levels of 32 elements in bee pollen samples were quantified using inductively coupled plasma-mass spectrometry (ICP-MS). Finally, calculations were performed to determine the recommended dietary allowance percentage (RDA%), estimated daily intake (EDI), target hazard quotient (THQ), and hazard index (HI). The bee pollen samples had varying levels of macro, trace, and ultratrace elements, with K, P, Ca, Mg, and Na being the most abundant macro elements and Ti, Ba, Ni, Cr, and V being the least abundant ultratrace elements. The RDA% values for essential elements in bee pollen were found to vary, with Cu, Zn, Fe, and Cr having the highest levels. The results of the THQ and HI calculations demonstrated that consuming bee pollen at recommended rates did not pose a risk to the health of adults or children.

Prevalence and determinants of insufficient vitamin D status in young Canadian Inuit children from Nunavik.

Background: Vitamin D deficiency has reached pandemic levels affecting over one billion people worldwide. However, limited data is available on the prevalence and determinants of vitamin D status of Canadian Indigenous children and no study has been reported in Inuit children from Nunavik. Aim: Therefore, using data collected between 2006 and 2010, we aimed to investigate the prevalence and main determinants of insufficient serum 25-hydroxyvitamin D (s25(OH)D) concentrations in Inuit children attending childcare centres in Nunavik. Methods: This study included 245 Inuit children aged 11 to 54 months. s25(OH)D concentrations were measured by radioimmunoassay. Dietary intakes were assessed using 24-hour recalls. Usual dietary intakes were estimated using the National Cancer Institute method. We used a multiple imputation technique to replace missing values when performing regression analysis. Results: Our findings revealed that 64.5% of children had a s25(OH)D concentration < 75 nmol/L, while 78.1% did not meet the estimated average requirement (EAR) for vitamin D. Vitamin D intake and fluid milk consumption were positively associated with s25(OH)D concentrations, while negative associations were observed with children' energy intake, non-alcoholic beverage consumption, body weight, breastfeeding duration and, biological/adoptive/foster parents' educational level. Conclusion: Vitamin D inadequacy was highly prevalent and closely aligned with levels observed over the years in non-Indigenous children. Breastfed children who do not receive vitamin D supplementation, overweight and obese children, and children with inadequate milk consumption were at high risk of vitamin D insufficiency. Eating vitamin D rich foods such as fluid milk and seafood along with vitamin D supplementation when needed are recommended.

The Importance of Dietary Protein Quality in Mid- to High-Income Countries

In wealthy countries, the protein intake of adults is usually considered to be adequate, and considerations of protein quality are often deemed irrelevant. The objective was to examine dietary protein intakes of adults in developed countries in the context of dietary protein quality. An analysis of NHANES population data on actual protein intakes in the United States (a developed country) demonstrated that for a dietary Digestible Indispensable Amino Acid Score (DIAAS) of 100%, 11% of the adult (19–50 y) population had habitual protein intakes below the Estimated Average Requirement (EAR) and 22% below the Recommended Dietary Allowance. The percentage of the population with utilizable protein intakes potentially falling below the EAR increased as the assumed DIAAS declined. Analysis of the NHANES data and several other datasets also indicated that total protein intakes can be limiting or close to limiting for the elderly and some vegetarians and vegans. Here, lower dietary protein quality can potentially lead to inadequate utilizable protein intakes. For many people in specific physiological states (e.g., weight loss, endurance sports, resistance exercise) attempting to meet higher dietary protein targets often with accompanying lowered energy intakes, low dietary protein quality can lead to protein calories expressed as a proportion of total calories, falling outside what may be acceptable limits (maximum of 30% protein calories from total calories). In general, individuals within the adult population may be susceptible to macronutrient imbalance (whenever total protein intakes are high, daily energy intakes low) and for diets with lower protein quality (DIAAS <100%). Our analysis shows that dietary protein quality is relevant in mid- to high-income countries.

Nutrient density of Bangladeshi foods and its application in planning diet for pregnant women.

Nutrient profiling is a method that classifies foods based on their nutrient content and identifies foods that are high in micronutrients both across and within food groups. This study aimed to identify foods that are rich sources of the seven micronutrients (iron, zinc, calcium, thiamine, riboflavin, vitamin A, and vitamin B12) of public health concern for the Bangladeshi population.. This study developed a metric termed "naturally nutrient-rich score 7 (NNR7)" specifically for third-trimester pregnant women to identify nutrient-dense foods. Further, it computed the nutrient adequacy score (NAS) of the top NNR7-scored foods for seven micronutrients to assess the extent (percent) to which foods can meet pregnant women's recommended dietary allowances (RDA). A linear programming technique was then used to construct a nutrient-adequate model diet for third-trimester pregnant women using the top ten NNR7-scored foods. According to the NNR7, food groups such as leafy vegetables, fish, meat, poultry and eggs, and vegetables are the richest sources of the problem micronutrients. Mutton liver (916.7%), soybean (39.3%), lamb liver (2160%) and duck liver (50.0%) were found to fulfill the highest percentage of the RDA of vitamin A, zinc, vitamin B12, and iron, respectively. In the formulated nutrient-adequate diets for pregnant women, rice, potato, brown wheat flour, and soya oil were universal to all three diets and Bengal gram, orange, Ganges River sprat, and duck liver were the most common ones. The study findings highlight the need for the consumption of foods such as leafy vegetables, fish, meat, poultry, eggs, pulses and vegetables to increase the intake of problematic micronutrients. Planning a nutrient-adequate diet for pregnant women using linear programming can be an alternative approach to optimize and shape food choices to meet their nutritional requirements.

Dietary Intake and Exposure Assessment of Trace Elements in Infants' Diets: A Case Study in Kuwait.

Different types of infant foods categorized as formulas, cereals, and purees imported from seven different countries and available on the Kuwaiti retail market were collected to determine the elemental content, including essential trace elements namely chromium (Cr), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), selenium (Se), and molybdenum (Mo); potentially toxic trace elements such as aluminum (Al), nickel (Ni), tin (Sn), antimony (Sb), and uranium (U); and toxic trace elements including arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg). The samples were analyzed using ICP-MS. An extensive literature search illustrated the uniqueness of this study since seven different essential elements, five different potentially toxic elements, and four different toxic trace elements were measured in a variety of infant foods; in addition, the different trace etlemental levels measured in the investigated infant foods were compared to the ones associated with the different infant foods types reported in the literature. The essential trace element concentrations detected in this study were implemented to calculate their total daily intake, where the calculated daily intake values were compared to their recommended dietary allowance (RDA) to assess the percentage total daily intake for the essential trace elements. Further, the calculated potentially toxic and toxic trace elements daily intake values were used to assess the potential health risks to infants incurred by consuming different infant foods by calculating the hazard quotient (HQ), while the margin of exposure (MOE) was calculated for the toxic ones only. It was concluded that infant formulas and foods should be added to the infant diet in addition to breast milk to meet specific nutritional needs. This study confirms that infants are exposed to toxic trace elements via diet, warranting careful attention to diet choices both to limit this exposure and to avert potentially hazardous adverse health effects to the infants. However, based on the calculated hazard quotients (HQs) and margin of exposures (MOEs), consuming breast milk in addition to almost all different types of infant foods is considered safe and unlikely to contribute to infants' non-cancerous health hazards.

A study on behavior, diet patterns and physical activity among selected GDM and non-GDM women in south India

Abstract Aim: Our aim is to study the behavior, diet, and physical activity patterns among gestational diabetes mellitus (GDM) and non-GDM women. Materials and Methods: A survey was conducted among GDM and non-GDM women from multispeciality hospitals and maternal clinics using a purposive sampling criterion. A validated interview schedule was used to obtain details of readiness for pregnancy, perception of managing pregnancy, concerns in pregnancy, degree of depression, food preferences, shopping of food, eating out, cooking, current nutrient intake, food consumption pattern, type, duration and frequency of physical activity, and rest periods of GDM and non-GDM women. Results: Majority of GDM and non-GDM women showed readiness for motherhood. GDM women exhibited greater confidence and importance toward making lifestyle changes during pregnancy. The pregnancy-related concerns were more common among GDM women. The mean energy and protein intake was lower than the recommended dietary allowance (RDA) among GDM women compared to their counterparts. On the contrary, carbohydrate consumption exceeded RDA among both groups. The total fat intake, including visible and invisible fat among GDM women, met the RDA; however, it exceeded the RDA among non-GDM women. The RDA for calcium, iron, and fiber showed significant difference compared to RDA among both groups. Physical activity patterns did not show any significant difference among GDM and non-GDM women and were unsatisfactory in both groups. Conclusion: The study recommends the need for psychological support, proper medical nutrition therapy, and adequate physical activity for GDM and non-GDM women.

UNVEILING THE NUTRITIONAL POTENTIAL OF STAR FRUIT (Averrhoa carambola): IN VITRO BIOACCESSIBILITY STUDY

A method was developed for quantifying the concentrations of Ca, Fe, Mg, and Zn in star fruit. An in vitro assay was used to evaluate the bioaccessibility of these elements after a simulated gastrointestinal digestion. The results showed that the total elemental concentration in star fruit were 78-186.2 mg kg-1 for Ca, 92.1-148.1 mg kg-1 for Mg, below the limit of detection for Fe and Zn. The bioaccessibility of Ca and Mg was 40 and 58%, respectively. These bioaccessibility percentages were attributed to the presence of an antinutrient in star fruit that promotes precipitation of insoluble compounds during the in vitro assay. Based on the data from gastrointestinal digestion assay, it is possible to conclude that star fruit intake can supply 1.6-2.04% and 11.2-19.6% of the recommended dietary allowance (RDA) of Ca and Mg, respectively.

Community Pharmacist's Awareness, Knowledge and Attitude Towards use of Vitamin Supplements in Pimpri-Chinchwad Municipal Corporation (PCMC) Area of Pune, India: A Descriptive Cross Sectional Study.

US FDA defines: dietary supplements is a product that intended to supplement a person's diet, it's generally consist of at least one or more of the following dietary ingredients, vitamin, minerals, a herb or other botanical and amino acid by increasing the daily consumptions of an extract metabolite concentration, constitute or combinations of these medication. Excessive and inappropriate use of medicines has been recognised as a public health problem resulting in increased likelihood of adverse drug event, drug interaction, and inappropriate drug prescribing and increased cost. This was the cross-sectional study conducted in year 2022 at Pimpri Chinchwad (Pune). The total 250 questionaires are distributed and from that 226 response were received. Target population consist of community pharmacists working in the drug store in this area (n=226). Data was represented in three domains of study i. e. awareness, knowledge and attitude. Correlation coefficient using Pearson's method were determined to evaluate strength of correlation between awareness-knowledge, Knowledge-attitude and awareness-attitude. Correlation coefficient were calculated by comparing most relevant and equal number of questions. The study demonstrated positive attitude among surveyed community pharmacists in Pune, India. There is lacuna in accurate and adequate awareness, knowledge and attitude of vitamin deficiency, efficiency, recommended daily allowance (RDA), toxicity and interactions among pharmacist as one of the stakeholders of healthcare in India. Few of the remedies viz. framing of guidelines, inclusion in formal education syllabus, continuous education, updation exams etc. may be of use.

Basal Metabolic Rate Versus Dietary Vitamin D and Calcium Intakes and the Association With Body Composition and Bone Health After Chronic Spinal Cord Injury.

We examined the association among basal metabolic rate (BMR) as well as dietary intakes of vitamin D (Vit D) and calcium on body composition and bone mineral density (BMD) after spinal cord injury (SCI). Cross-sectional design. Veterans Affairs Medical Center, Richmond, VA. About 33 individuals with chronic SCI who recorded their food consumption 3 days per week for 2 weeks. BMR was measured after 10 to 12 h of overnight fast. Average daily vit D and calcium intakes, and total caloric intake were recorded and analyzed using the Nutrition Data System for Research (NDSR) software. Fasting blood analysis for 25-hydroxyvitamin D (25[OH]D) status and Triiodothyronine (T3) status was performed (n = 10). Total and regional BMD, % fat mass (FM), and % lean mass (LM) were measured by dual X-ray absorptiometry scans. Participants consumed less than the Institute of Medicine (IOM) recommended daily allowances (RDA) for vit D (600-800 IU) and calcium (1000-1200 mg) for adults. BMR was positively related to total-lean mass (r = .62, P = .0001; n = 32) and leg-lean mass (r = .51, P = .003; n = 32). Adjusted BMR was negatively related to BMD of the left (r = -.38, P = .047; n = 28) and the right (r = -.41, P = .032; n = 28) proximal tibia. Vit D intake was negatively related to percentage total-FM (r = -.33, P = .07; n = 29) and legs-%FM (r = -.37, P = .047; n = 29). Multivariate regression models indicated that adjusted BMR explained the variance in leg fat mass (34%; P = .002) and percentage fat mass (44%; P < .0001). Persons with SCI are likely to consume less than the RDAs for vit D and calcium. BMR may explain the changes in body composition and bone metabolism. Dietary vit D should be considered as a prophylactic intervention in maintenance of bone health after SCI.

Использование витаминов группы В в профилактических и лечебных дозах при сахарном диабете 2-го типа

Polyhypovitaminosis is a risk factor for many diseases. Adequate dietary intake of vitamins may help prevent/reduce the risk of progression of several diseases, including type 2 diabetes (T2D). Objective. To analyze the sufficiency of B vitamins and efficacy of their administration in patients with T2D depending on the dose. Vitamin deficiencies typical for patients with T2D worsen the course of the disease and increase the risk of complications. Higher intake of vitamins B1, B2 and folate is associated with a lower risk of T2D, and higher intake of folate and vitamin B6 is associated with a lower risk of cardiovascular diseases in patients with T2D. Higher intake of vitamin B6 by individuals with T2D is associated with a lower incidence of diabetic retinopathy. In T2D patients, low levels of the coenzyme form of vitamin B6 and high serum levels of 4-pyridoxic acid increase the risk of all-cause mortality. Patients with diabetic retinopathy have significantly reduced levels of vitamin B12. The incidence of vitamin B2 deficiency based on serum levels is found in approximately 30–40% of patients with T2D and diabetic nephropathy. Metformin administration worsens vitamin B12 supply and increases the risk of T2D complications. The need to eliminate vitamin deficiencies and improve the sufficiency of B vitamins is undeniable. There are prophylactic and therapeutic doses of vitamins. Continuous intake of multivitamin supplements with a complete set of all B vitamins in prophylactic doses consistent with the recommended daily intake (RDI) will reduce the risk of T2D progression. Administration of B vitamins during 1 month to 5 years in therapeutic doses well above the RDI results in improvement of carbohydrate metabolism, antioxidant and clinical status in patients with T2D, but may lead to undesirable effects. Conclusion. When prescribing B vitamins to T2D patients, it is recommended to distinguish between prophylactic doses of vitamins that meet the body’s needs and can and should be taken continuously, and therapeutic doses, that are close to the upper safe intake level and may cause adverse reactions. Key words: type 2 diabetes, B vitamins, sufficiency, prophylactic and therapeutic doses of vitamins

Determination of protein content in cooked foods consumed by toddlers aged 1-2 years in Sri Lanka

In early life, protein deficiency as well as heavy protein intake cause adverse conditions. Therefore, the present study aimed to assess the protein adequacy of diets in 1-2-year-old toddlers in the Alawwa Medical Officer of Health (MOH) area, Kurunegala, Sri Lanka. Data on food consumption was obtained by 24-hour dietary recall method from selected caregivers (n=60) andcommonly consumed foods (n=30) were cooked using household preparation protocols practiced in the area. They were homogenized and analyzed for protein. The majority of toddlers among the selected population consumed rice-based meals (73%) as the main meal (cooked rice with vegetable accompaniments), while 27% preferred mixed diets (a mixture of vegetables, pulses, leafy vegetables and fish along with rice). A serving of commercial cereal products provided the highest estimateddaily intake (EDI) of protein (10.70 ± 0.40 g). The average EDI of protein of all categories of foods per portion (rice, vegetables, pulses, green leaves, fish, eggs, rice mixtures and cereal products) was 31.55 ± 0.88 g, contributing to the recommended dietary allowance (RDA) of 242.64% and 150.17% for 1-2 year toddlers as defined by the Department of Agriculture, United States (USDA) and Sri Lankan RDA defined by Medical Research Institute (MRI), respectively. In conclusion, the cooked foods prepared according to local recipes fulfilled the dietary requirements of protein for toddlers aged 1-2 years in the Alawwa MOH area following USDA and Sri Lankan nutrition guidelines.&#x0D; Keywords: Estimated Daily Intake, Protein, Recommended Dietary Allowance, Toddlers

The nutritional content per 30g serving of the black wheat snack bar with hibiscus flavor included 21.9g of carbohydrates, 4.4g of fat, and 1.6g of fiber. Therefore, by consuming this snack bar, 7% of the RDA for carbohydrates, 7% of the RDA for fat, and 5% of the RDA for fiber can be met. In conclusion, this product can be recommended to individuals who want to maintain their health despite frequent snack consumption.

Added Sugars Consumption Decreased Iron and Zinc Intake among Children Aged 24-59 Months in Central Java

Background: High sugar consumption was found among children in Indonesia. Excessive intake of added sugars was predicted to cause micronutrient dilution, a negative potential effect compromising micronutrient intake such as iron and zinc. Objectives: This study examined the association between added sugar consumption and iron and zinc intake among children aged 24-59 months. Methods: This study was a secondary data analysis of the 2014 Total Diet Study in Central Java Province. The subjects were 394 children aged 24-59 months. Dietary intake and sociodemographic data were assessed using the 24-hour food recall and household questionnaire. Added sugars consumption was classified into six cut-offs based on its contribution to daily energy (%E), namely: C1 (&lt;5%E), C2 (5%E - &lt;10%E), C3 (10%E - &lt;15%E), C4 (15%E - &lt;20%E), C5 (20%E - 25%E), and C6 (&gt;25%E). Results: 48% of subjects had added sugar intake exceeding the WHO recommendation. Subjects with iron and zinc intake below the Estimated Average Requirement (EAR) were 15.2% and 24.1%, respectively. As the added sugar consumption increased, iron and zinc intake decreased significantly (p&lt;0.05). This study found a significant decrease in the intake of iron occurred at added sugar consumption ≥20%E (C5 and above) while decreasing the intake of zinc at added sugar consumption ≥15%E (C4 and above) (p&lt;0,05). Conclusions: Added sugar consumption had an inverse association with iron and zinc intake among children aged 24-59 months, which showed the occurrence of micronutrient dilution.

Development of micronutrients and bioactive compounds rich malted drink with selected plant-based ingredients.

The study aims to develop a micronutrients and bioactive compounds rich, new malted drink formula using malted green gram (Vigna radiata), soybeans (Glycine max), watermelon (Citrullus lanatus) seed kernel and ginger (Zingiber officinale) rhizomes. The sensory analysis data revealed that the formula which contains 52.17 % of soybean flour, 26.00 % of malted green gram flour, 17.39 % of watermelon seed kernel flour and 4.34 % of ginger powder has the highest overall acceptability. This selected formula contained moisture (3.27 ± 0.29 %), total ash (3.96 ± 0.39 %), total fat (12.93 ± 0.19 %), protein (33.58 ± 0.64 %), crude fiber (2.70 ± 0.49 %), carbohydrate (43.56 ± 0.89 %), reducing sugars (4.98 ± 0.13 %) and dietary fiber (18.67 ± 0.36 %). Considerable amounts (mg/100 g) of Potassium (2332.19 ± 5.69), Phosphorus (1003.78 ± 9.12) and Magnesium (374.07 ± 3.36) were reported. The fatty acid profile was dominated by polyunsaturated fatty acids (60.53 %) including Linoleic acid (56.40 %) and α-Linolenic Acid (4.13 %). The detected amounts of prominent micronutrients and α-Linolenic Acid adequately comply with the Recommended Dietary Allowance (RDA) values. Moreover, the new formula possessed 2.3 ± 0.11 mg GAE/g of total phenolic compounds and exhibited significantly high DPPH (12.81 ± 2.19 mg/ml) and ABTS (25.16 ± 0.41 mg/ml) radical scavenging activities.
