Modeling Zinc Absorption in the Adult Population of Colombia: Insights for Nutritional Evaluation and Intervention Strategies.

Zinc is a vital trace element, yet its deficiency is common in various populations. This study addresses the gap in understanding zinc intake and its relationship with key nutritional parameters in a Colombian population. We analyzed data from 12,987 individuals, focusing on the daily intake of zinc, phytate, protein, and calcium, and used the phytate/zinc molar ratio as an input parameter in the Miller et al. (2013) model. This model was employed to estimate the total absorbed zinc (TAZ) and the fractional absorption of zinc (FAZ). Our findings highlight a general trend towards insufficient intake compared to the standards of the Institute of Medicine (IOM) and Colombia, with a significant percentage of the population falling below the estimated average requirement (EAR) and recommended daily allowance (RDA) for zinc, underscoring the need for targeted nutritional strategies. Our study contributes to a broader understanding of zinc nutrition and public health implications in Colombia, providing a basis for future dietary guidelines and health interventions.

Assessing the Nutrient Intake, Energy Expenditure and Physical Activity Level of Obese and Non-obese Women in Hisar District, India: A Cross Sectional Study

The present study was conducted on thirty obese and thirty non-obese women (30-45 years) of Hisar district, Haryana to assess their mean nutrient intake, adequacy of intake of different nutrients, energy expenditure and physical activity level. The subjects did not exhibit any health complications and, overall, were in a state of good health. It was found that the mean intake of energy, protein, fat, folic acid and magnesium by respondents was comparable to Recommended Dietary Allowances (RDA) i.e 98 to 129 per cent of RDA. But when assessed on parameter of adequacy it was found that only 50 to 53.3 percent of respondents consumed adequate protein. Intake of most of the nutrients (iron, β-carotene, folic acid) under study, by them, was marginally adequate to inadequate when compared to the recommended values (with few exceptions). Calcium intake of 50 per cent of non-obese women was adequate while iron intake of 66.7 per cent of them was 50 to 74.9 per cent of RDA. All the obese and non-obese women were sedentary workers and consumed more energy than their requirement. This low intake in their nutrient intake may be due to inadequate intake of protective foods and it was felt that they need awareness regarding balanced diet and endorse adoption of a healthy life style by including minimum of 30 minutes of physical activity in their daily routines.

The effects of whey, pea, and collagen protein supplementation beyond the recommended dietary allowance on integrated myofibrillar protein synthetic rates in older males: a randomized controlled trial

BackgroundSkeletal muscle mass is determined predominantly by feeding- and activity-induced fluctuations in muscle protein synthesis (MPS). Older individuals display a diminished MPS response to protein ingestion, referred to as age-related anabolic resistance, that contributes to the progression of age-related muscle loss – sarcopenia. ObjectiveWe aimed to determine the impact of consuming higher- versus lower-quality protein supplements above the recommended dietary allowance (RDA) on integrated MPS rates. We hypothesized that increasing total protein intake above the RDA, regardless of the source, would support higher integrated rates of myofibrillar protein synthesis. MethodsThirty-one healthy older males (72 ± 4 y) underwent a controlled diet with protein intake set at the RDA – control phase (CON; days 1-7). In a double-blind, randomized controlled fashion, participants were assigned to consume an additional 50g (2x25g) of Whey (WHEY, n=10), Pea (PEA, n=11), or collagen (COLL, n=10) protein each day (25 g at breakfast and lunch) during the supplemental phase (SUPP; days 8-15). Deuterated water ingestion and muscle biopsies assessed integrated MPS and acute anabolic signaling. Postprandial blood samples were collected to determine feeding-induced aminoacidemia. ResultsIntegrated-MPS was increased during SUPP with WHEY (1.59 ± 0.11 %/d, p<0.001) and PEA (1.59 ± 0.14 %/d, p<0.001) when compared with RDA (1.46 ± 0.09 %/d WHEY; 1.46 ± 0.10 %/d PEA); however, it remained unchanged with COLL. Supplemental protein was sufficient to overcome anabolic signaling deficits (mTORC1 and rpS6), corroborating the greater postprandial aminoacidemia. ConclusionsOur findings demonstrate that supplemental protein provided at breakfast and lunch over the current RDA enhanced anabolic signaling and integrated MPS in older males; however, the source of additional protein may be an important consideration in overcoming age-related anabolic resistance.Clinical Trial Registry number and website where it was obtained This trial (NCT04026607) was registered clinicaltrials.gov;

Trends in Reported Calcium and Magnesium Intake from Diet and Supplements by Demographic Factors: National Health and Nutrition Examination Survey, 2003-2018

BackgroundCalcium and magnesium are important micronutrients necessary for normal body functioning. ObjectiveThe objective of the study was to approximate usual nutrient intakes and estimate proportion of adults meeting the Estimated Average Requirement (EAR) of calcium and magnesium from diet, and diet plus supplements (total intake). Trends in the proportion of adults meeting the EAR were estimated by sex, age, and race and ethnicity. DesignThe study utilized data from the National Health and Nutrition Examination Survey, a cross-sectional survey of a nationally representative sample of the US civilian and noninstitutionalized population. Participants and settingThe continuous National Health and Nutrition Examination Survey survey data from 2003-2004 through 2017-2018 for dietary intake, and 2007-2008 through 2017-2018 for total intake were analyzed. The study sample included men and women (not lactating/pregnant) ages 19 years and older with 2 reliable 24-hour dietary recalls and energy intake >500 to <6,000 kcal/day (N = 35,037). Main outcome measuresMean daily intake and trends of proportion of adults meeting/exceeding the EAR for calcium and magnesium were estimated. Statistical analyses performedThe National Cancer Institute’s method was used to calculate daily intakes for calcium and magnesium by demographic subgroups. SAS SURVEYMEAN and SURVEYFREQ procedures were used to estimate means ± SE for continuous variables and frequencies and percentages for categorical variables, and 2-sample t test for P values. Trends were estimated with National Cancer Institute’s Joinpoint trend analysis program. ResultsMean daily dietary calcium intake and proportions of adults meeting the EAR from both diet and supplements was lowest among women (859 mg [61.9%]), adults ages 71 years and older (865 mg [60.3%]) and non-Hispanic Black individuals (782 mg [48.6%]) compared with men, younger age groups, and other races and ethnicities. Magnesium intake reported from diet was lowest in adults ages 71 years and older (276 mg), whereas total magnesium intake and proportion of meeting the EAR from both diet and supplements was lowest in women (302 mg) and men (52%), respectively, adults ages 19 to 30 years (305 mg [48.5%]), and non-Hispanic Black individuals (274 mg [35.5%]). The trends in the proportion of women and non-Hispanic White adults meeting the EAR from total calcium intake decreased significantly (P < .05) by 2.9% and 2.0%, respectively. ConclusionsWomen and adults ages 71 years and older had the lowest reported mean daily dietary calcium intake and proportion meeting the EAR for calcium from diet and supplements. Men and adults ages 19 to 30 years had the lowest proportion meeting the EAR for magnesium from diet and supplements with adults ages 19 to 30 years also having the lowest reported total magnesium intake from diet and supplements. Non-Hispanic Black individuals had the lowest proportion of meeting the EARs for calcium and magnesium from reported total intake. The trends in the proportion of women and non-Hispanic White individuals meeting the EARs for calcium through total intake decreased over time and remained stable in other subpopulations and for magnesium.

Assessment of the prevalence of inadequate iron intakes in premenopausal females based on the reference values of the European Food Safety Authority using cross-sectional food consumption data

BackgroundThe iron intake requirement distribution for premenopausal females is not symmetric, which invalidates the EAR (Estimated Average Requirement) cut-point approach for assessing prevalence of iron inadequacy. Therefore, Beaton’s Full Probability Approach (PA) must be used. While the PA requires information on the entire iron intake requirement distribution, the European Food Safety Authority (EFSA) only provided the EAR (50th percentile), 90th, 95th (PRI) and 97.5th percentiles. ObjectiveThis study aimed to reliably estimate the prevalence of iron inadequacy in premenopausal females using the PA, based on the intake requirements established by EFSA and compare the results with those obtained from the EAR cut-point method. MethodsHabitual iron intakes were calculated using Statistical Program to Assess Dietary Exposure (SPADE) with data from 484 females (20-45 y) from the Dutch National Food Consumption Survey 2012-2016. Iron requirement of EFSA (including additionally obtained information) were applied. Results from the PA were compared to results obtained with the EAR cut-point method. Sensitivity analyses examined the impact of lower iron intake distributions on differences in estimated inadequate intakes between PA and EAR-cut point method. ResultsA twofold higher prevalence of iron inadequacy among Dutch premenopausal females was observed when employing the PA compared to the EAR cut-point method, using EFSA’s reference values. Sensitivity analysis showed that the EAR cut-point method could also result in large overestimations for populations with lower intake distributions. ConclusionsThis study provided an example for using the PA method by using additionally derived information on the full requirement distribution underlying EFSA’s reference values. Results showed once more the unsuitability of the EAR cut-point method to calculate the prevalence of iron inadequacy in premenopausal females. Hence, we recommend that institutions deriving dietary reference values provide all information needed to use the correct method to determine inadequate intakes in the population.

АЛГОРИТМ ЭФФЕКТИВНОГО ПРИМЕНЕНИЯ ВИТАМИННО-МИНЕРАЛЬНЫХ КОМПЛЕКСОВ

At present time, there is a huge range of vitamin and mineral supplements (VMS), that differ in composition and doses of micronutrients, which complicates the choice and their effective use. The purpose of the review is to substantiate the algorithm for effective use of VMS for the correction of micronutrient deficiency. The general pattern in the VMS administration is that there is an inverse relationship between the dose of micronutrients and the increase in their concentration in a fasting blood test after an overnight break. Improving vitamin status requires time, that is longer when taking VMS with low doses, and for each vitamin the time to achieve optimal concentrations is different. To optimize the vitamin status by means of VMS administration containing vitamins in doses corresponding to 100% of the recommended daily intake (RDI) takes from 1.5 months for B vitamins to 3-5 months for vitamin D. A course of VMS administration for 1 months may not be enough to correct the deficiency of all vitamins. After stopping additional use of VMS, a “wash-out” of vitamins occurs for one to several weeks, i.e. decrease of blood concentration and return to the original state of deficiency. A universal, scientifically based scheme for the effective use of VMS consists of a course of VMS administration with high (200-300% of the RDI) micronutrients, especially after an illness or taking antibiotics, and then switching to constant use of VMS containing deficient micronutrients in a dose of 50-100 % of RDI. Women during the periconceptional period and throughout pregnancy are recommended to take daily multicomponent VMS, specifically designed for pregnant women, containing doses of micronutrients that correspond to the physiological needs of the body.

Assessing Performance of Contemporary Plant-Based Diets against the UK Dietary Guidelines: Findings from the Feeding the Future (FEED) Study.

Uncertainty remains about the composition of contemporary plant-based diets and whether they provide recommended nutrient intakes. We established Feeding the Future (FEED), an up-to-date online cohort of UK adults following different plant-based diets and diets containing meat and fish. We recruited 6342 participants aged 18-99 [omnivores (1562), flexitarians (1349), pescatarians (568), vegetarians (1292), and vegans (1571)] between February 2022 and December 2023, and measured diet using a food frequency questionnaire and free text. We compared personal characteristics and dietary intakes between diet groups and assessed compliance with dietary guidelines. Most participants met UK dietary recommendations for fruit and vegetables, sodium, and protein, although protein intakes were lowest among vegetarians and vegans. Omnivores did not meet the fibre recommendation and only vegans met the saturated fat recommendation. All diet groups exceeded the free sugars recommendation. Higher proportions of vegetarians and vegans were below the estimated average requirements (EARs) for zinc, iodine, selenium, and, in vegans, vitamins A and B12, whereas calcium intakes were similar across the diet groups. People following plant-based diets showed good compliance with most dietary targets, and their risk for inadequate intakes of certain nutrients might be mitigated by improved dietary choices and/or food fortification.

Eating Disorders Among Saudi Dietitians: Prevalence and Analysis

Eating disorders (EDs) involve persistently disturbed eating and related behaviors that result in altered consumption or absorption of food with potential physical or psychological function impairment. There are four major types of EDs: anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorders not otherwise specified. This investigation aimed to study the prevalence of EDs by assessing the nutritional status of nutrition students and dietitians from multiple provinces in Saudi Arabia. A cross-sectional study included 175 male and female nutrition students and dietitians. EDs were diagnosed using the Eating Attitudes Test – 26 item (EAT-26) and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Dietary intake was estimated using repeated 24-hour recall records. Diets were analyzed using food processor nutrition and fitness software. The intakes were compared with the recommended dietary allowances (RDA). The mean participant age was 24.62 ± 4 years. According to EAT-26 diagnostic criteria, the prevalence of EDs was 15.4%. The ED participants had normal body mass index values of 23.6 ± 3.47kg/m2. The diet analysis showed that these subjects had a lower intake of energy, macronutrients, and micronutrients but higher intakes of other micronutrients than the RDA. Nine (33.3%) of the subjects were students and 18 (66.7%) were dietitians. l EDs were more prevalent among dietitians than students. The EDs included a high number of other specified feeding or eating disorders and unspecified eating disorder cases. Subjects with ED had an unbalanced diet and poor nutrition. Our investigation concluded that the prevalence of EDs in Saudi Arabia was 15.4% among nutrition students and dietitians. Moreover, EDs were more prevalent in some provinces of Saudi Arabia. Intakes of energy, macronutrients, and some micronutrients were low, while those of other micronutrients were higher than the RDA.

Occurrence of heavy metals coupled with elevated levels of essential elements in chocolates: Health risk assessment

The presence of contaminants in cacao-derived products, especially in chocolates, has raised concerns regarding food safety and human health. The study assessed the concentration variation of 16 elements in 155 chocolate samples from the US market by cacao content and country of geographic origin. The study further examined the potential health risks posed by toxic metals and determined the contribution of essential elements to the Daily Recommended Intake (DRI), estimated based on an ounce (∼28.4 g) of daily chocolate consumption. Dark chocolates with ≥50 % cacao exhibited consecutively increasing mean levels from 1.2 to 391 µg/kg for U, Tl, Th, As, Pb, Se, Cd, and Co. Similarly, Ni, Sr, Cu, Mn, Zn, Fe, Ca, and Mg had mean concentrations from 4.0 to 1890 mg/kg. Dark chocolates sourced from Central and South America exhibited the highest mean levels of Cd, and South America samples also contained elevated Pb, whereas those from West Africa and Asia had low Cd and Pb, respectively. Cacao contents showed increasingly strong association with Cd, Co, Mn, Sr, Ni, Cu, Zn, and Mg (r = 0.60–0.84), and moderately with Se, Fe, As, and Tl (r = 0.35–0.49), indicating these elements are primarily derived from cacao beans. Weak association of cacao contents with Pb, Th, and U levels (r < 0.25), indicates post-harvest contaminations. Hazard Quotient (HQ) > 1 was found only for Cd in 4 dark chocolates, and Hazard Index (HI) > 1 for cumulative risk of Cd, Pb, Ni, As, and U was found in 33 dark chocolates, indicating potential non-carcinogenic risks for 15 kg children but none for 70 kg adults. Dark chocolate also substantially contributed to 47–95 % of the DRI of Cu for children and 50 % for adults. Dark chocolates also provided notable Fe, Mn, Mg, and Zn contributions to the DRI. These essential elements are recognized to reduce the bioavailability of toxic metals such as Cd, Pb, or Ni, thereby potentially lowering associated health risks. This study informs consumers, food industries, and regulatory agencies to target cacao origins or chocolate brands with lower toxic metal contents for food safety and minimizing adverse health effects.

Optimal Dietary Intake of Riboflavin Associated with Lower Risk of Cervical Cancer in Korea: Korean National Health and Nutrition Examination Survey 2010-2021.

This study aimed to evaluate the association between the dietary intake of vitamin B complex (thiamine, riboflavin, and niacin) and cervical cancer in Korea. The data from the Korean National Health and Nutrition Examination Survey (KNHANES) from 2010 to 2021 were analyzed, which included 28,306 participants who were categorized into non-cervical cancer and cervical cancer groups. The following dietary intake threshold levels of thiamine, riboflavin, and niacin were identified based on the recommended daily allowances (RDAs): thiamine, 1.1 mg/day; riboflavin, 1.2 mg/day; and niacin, 14 mg/day. Among 28,306 participants, 27,976 were in the non-cervical cancer group and 330 were in the cervical cancer group. Riboflavin intakes of more than 1.2 mg/day but less than 2.4 mg/day were associated with a significantly reduced risk of cervical cancer, whereas intakes of above 2.4 mg/day were not associated with cervical cancer. Thiamine and niacin intakes were not significantly related to the risk of cervical cancer. The results of this study suggest that an intake of riboflavin of 1.2-2.4 mg/day may contribute to a lower risk of cervical cancer.

Evaluation of the potential implications of following a vegan diet on bone health

Cow’s milk is the primary source of calcium in the NZ diet(1). The absence of dietary planning in a vegan diet can result in the individual unknowingly obtaining low intakes of calcium. Prolonged low calcium intakes can result in negative implications on bone mineral density by increasing the risk of osteoporosis later in life. The measurement of bone health parameters in NZ vegan adults have not been investigated. Therefore, we measured bone mineral density, markers of calcium homeostasis and assessed intake of essential nutrients for optimal bone health in vegans. This cross-sectional study included adults (&gt;18yrs), who followed a vegan diet for 2 years minimum. Demographic and lifestyle information was obtained from questionnaires including previous history of bone fractures and background of familial osteoporosis. A 4-day food record was completed for analysis of calcium, zinc, protein, magnesium, phosphorus and vitamin C intake and compared to the Estimated Average Requirement (EAR)(2). Weight, height and BMI were obtained, bone mineral density was measured at the hip and spine via dual x-ray absorptiometry (DXA) and reported as Z and T scores. Plasma calcium concentrations were corrected for albumin. All values are presented as mean and standard deviation. The study included 212 participants, aged 39 ± 12.38 years, 71% female. T scores at the lumbar spine and femoral neck were −0.63 ± 1.22 (Z score: −0.29 ± 1.12) and −0.66 ± 1.00 (Z score: −0.24 ± 0.89), respectively. Nine participants had a Z-score of &lt;-2.0 at the lumbar spine, and three at the femoral neck. Corrected calcium concentrations were 2.21 ± 0.33 mmol/L. Calcium intake was 917 ± 347.23 (range 195 to 2,429 mg/day) in all participants, which exceeded the EAR of 840 mg/day for adults aged 19-50 years. Men had higher intakes of calcium than women, 1,051 ± 363.7 mg/day (range 382 to 2,267 mg/day) vs. 867 ± 328.04 mg/day (range 194 to 2,428 mg/day), P-value &lt;0.001. The main source of calcium in the vegan diet was tofu. The intake of protein (77 ± 27.80) g/day, magnesium (569 ± 181.05) mg/day, and vitamin C (145 ± 96.94) mg/day met the EAR, excluding vitamin and mineral supplements. However, the intake of phosphorus (1,472 ± 459.98) mg/day and zinc (10.6 ± 4.01) mg/day were below the EAR. The findings of this study suggest that bone health of vegans are not negatively affected by the exclusion of dairy in the diet, provided that appropriate dietary planning is included to avoid nutrient deficiencies associated with poor bone health. Despite mean intake of calcium exceeding the EAR, very low intakes demonstrated significant variations between participants.

The effect of motivation type on intake and nutritional status of vitamin B12, omega-3 fatty acids, iron and nutrition knowledge in individuals following a vegan diet

The fundamental principle of veganism is to avoid all possible animal exploitation and therefore, animal ethics has always been a primary motivator. Nowadays, the environment and health are also common motivators. Omission of all animal products leads to dietary exclusion of vitamin B12, limited intake of omega-3 fatty acids, specifically EPA and DHA, and intake of low bioavailable iron sources1. Obtaining the knowledge to appropriately plan and replace nutrients through food or supplementation is key to avoiding deficiencies and subsequent consequences. This study aimed to determine the effect of motivation for being vegan on intake of key nutrients and nutritional knowledge. This cross-sectional, observational study recruited participants, who had followed a vegan diet for minimum 2 years. Demographics and nutrition knowledge were obtained from questionnaires. Motivation type was determined using the validated vegetarian eating motives inventory (VEMI) – participants scored the importance of animal ethic, environment and health. Intakes of vitamin B12 and iron, were collected using a 4-day food diary and assessed against Estimated Average Requirement (EAR). Blood samples were taken to determine status of vitamin B12, haemoglobin, serum ferritin, and omega-3 index. Omega-3 index score ≤4 indicates increased risk of coronary heart disease. Animal ethics was the greatest motivator to become vegan, with 83.5% of participants scoring it as very important, compared to 71.7% of people stating the environment, and 53.3% stating health. No association was found between all motivation types and intake of vitamin B12 and iron, nor omega-3 index. Mean vitamin B12 intake (supplements excluded) of 2.11ug/day ± 3.43 exceeded the EAR of 2.0ug/day for both men and women, however intakes ranged between 0.00 and 37.63ug/day. Mean intake of iron (18.77mg/day) exceeded the EAR for both men and women. Overall mean omega-3 index was 3.16%. Both men (162.24g/L) and women (151.44g/L) had adequate mean Hb serum concentrations. Mean serum ferritin was within normal range for both men (64.86ug/L ± 43.48) and women (32.55ug/L ± 26.04). Overall mean serum vitamin B12 was within normal range (316.54pmol/L ± 146.18), however a large range was observed from 72.00pmol/L to 1,015pmol/L. Males and females had similar knowledge, with only one question regarding fibre content in cornflakes found to be significantly different (P = 0.012). Knowledge was varied e.g., 100% of participants could identify that pasta was a carbohydrate source, yet could not identify which fats are most important to reduce. Mean vitamin B12 intake exceeding EAR and normal status despite limited vegan sources, indicates high consumption of high bioavailable fortified foods, and supplementation. Iron status shows large consumption of iron rich foods to overcome bioavailability issues, reflected by adequate iron intake, after increasing EAR by 80% to meet recommendations. The mean omega-3 index shows a low cardioprotective omega-3 fatty acid intake.

Intake of micronutrients implicated in depression amongst young adults consuming vegetarian diets: a secondary analysis of the 2011-12 National Nutrition and Physical Activity Survey

Major depressive disorder (‘depression’) is significantly more prevalent amongst young adults in Australia relative to older ages. The inefficacy of current treatment options for many individuals(1) warrants investigation of additional approaches to alleviating the burden of this illness. Incidentally, diet often becomes unhealthier during the transition from adolescence to young adulthood(2). This can result in poorer micronutrient consumption, and there is a growing body of evidence indicating that an inverse relationship exists between intake of certain micronutrients and depressive symptoms(3). Given this, diet may be an important modifiable risk factor or adjunctive means of ameliorating depression for young adults. Young adult vegetarians in particular have an increased risk of some micronutrient deficiencies which have been implicated in depression(4). In combination, their age and dietary choice suggest they may be especially vulnerable to depression and therefore benefit from clear guidance to adequately meet their micronutrient requirements. The present study aimed to elucidate the need for such guidance by comparing the proportions of vegetarian and omnivorous young adult participants in the 2011-12 National Nutrition and Physical Activity Survey (NNPAS) who had inadequate intakes of micronutrients implicated in depression. The NNPAS collected the most recent nationally-representative data pertaining to the dietary intake (via two 24-h recalls) of Australians and included 2,397 young adults (18-34 years). Participants who were pregnant, lactating, or who mis-reported intakes according to Goldberg equation-derived cut-off values were excluded (n = 791). The dietary data were used to estimate usual intakes via the Multiple Source Method. Inadequate intakes were identified according to the Estimated Average Requirement (EAR) cut-point method for all micronutrients with an EAR except iron, for which the full-probability method was applied. Survey weights allocated for inference to the total Australian population were implemented throughout the analysis. The final sample was composed of 66 vegetarians (did not report any animal tissue consumption) and 1540 omnivores. The mean intake of long-chain omega-3 fatty acids (EPA, DPA, DHA) from both diet and supplementation was significantly lower in vegetarians compared to omnivores (96.3mg/day vs. 264.5mg/day, p&lt;0.001). A significantly greater proportion of vegetarians compared to omnivores had inadequate total B12 (22.7% vs. 1.4%), iron (58.3% vs. 18.9%), selenium (30.8% vs. 3.5%) and zinc (58.8% vs. 33.3%) intakes (all p&lt;0.05). These results suggest that young adult vegetarians are likely to have significantly lower consumption of long-chain omega-3 fatty acids and an increased risk of inadequately consuming vitamin B12, iron, selenium and zinc compared to their omnivorous counterparts. These findings support the notion that young adult vegetarians may have an increased risk of depression from a nutritional standpoint, and therefore stand to benefit from tailored dietary advice on a public and individual level designed to support their mental health.

Minerals and trace elements in broad-leaved Geebung (Persoonia stradbrokensis), an underutilised native Australian fruit

Minerals and trace elements are essential for human health and wellness. Fruits can be an important dietary source of these micronutrients. For centuries, native Australian fruits have been a vital source of nutrition and well-being for the Indigenous Communities(1). However, comprehensive information on the mineral and trace element composition of these native fruits, including broad-leaved Geebung (Persoonia stradbrokensis), is lacking. Therefore, the aim of the present study was to determine the mineral and trace element composition of broad-leaved Geebung, an important but still underutilised native Australian fruit, at different maturity stages. Inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma-optical emission spectroscopy (ICP-OES) were used to analyse the fruit. Statistical analysis was performed using one-way ANOVA and the means (n = 3) were compared by Tukey’s multiple comparison post hoc test with p &lt; 0.05 as significant. Calcium and potassium could be identified as the main minerals, and iron, zinc and manganese as the main trace elements. The calcium content in broad-leaved Geebung was lower than Australian desert lime, kakadu plum, and riberry, respectively (35.7-271.5 vs. 384.2 vs. 282.5 vs. 307.7 mg/100g dry weight (DW))(2). Potassium has a vital role in the prevention of bone loss and is essential for the heart, kidney, and blood pressure. The potassium content of broad-leaved Geebung fruit was lower than Australian desert lime, kakadu plum, lemon aspen, quandong and riberry (average 516.4 vs. 1287.8 vs. 1905.5 vs. 1512.9 vs. 3456.2 vs. 1715.7 mg/100g DW)(2), which contributes to approximately 15% recommended dietary allowance (RDA). Iron is the main element in the production of hemoglobin and is important for maintaining healthy blood. Iron content in the fruit ranged from 0.8-2.6 mg/100g DW, which was higher than that of Davidson’s plum (1.2 mg/100g DW), but lower than the Green Plum, Australian desert lime, and kakadu plum (3.8 vs. 4.7 vs. 4.0 mg/100g DW) (2,3). Besides, the manganese levels were relatively high in broad-leaved Geebung fruit and considerably higher than in other native Australian fruits such as Kakadu plums, Desert limes and Quandongs (11.2-26.4 vs. 3.5 vs. 0.9 vs. 0.3 mg/100 g DW)(2). Interestingly, the mineral and trace element content decreased (p &lt; 0.05) during fruit maturity. In general, broad-leaved Geebung fruit can provide considerable amounts of essential minerals and trace elements and its potential as a healthy “snack” alternative should be investigated further.

Household food insecurity and associations with energy, nutrient intake, and sociodemographic characteristics in young New Zealand children

Although food insecurity affects a significant proportion of young children in New Zealand (NZ)(1), evidence of its association with dietary intake and sociodemographic characteristics in this population is lacking. This study aims to assess the household food security status of young NZ children and its association with energy and nutrient intake and sociodemographic factors. This study included 289 caregiver and child (1-3 years old) dyads from the same household in either Auckland, Wellington, or Dunedin, NZ. Household food security status was determined using a validated and NZ-specific eight-item questionnaire(2). Usual dietary intake was determined from two 24-hour food recalls, using the multiple source method(3). The prevalence of inadequate nutrient intake was assessed using the Estimated Average Requirement (EAR) cut-point method and full probability approach. Sociodemographic factors (i.e., socioeconomic status, ethnicity, caregiver education, employment status, household size and structure) were collected from questionnaires. Linear regression models were used to estimate associations with statistical significance set at p &lt;0.05. Over 30% of participants had experienced food insecurity in the past 12 months. Of all eight indicator statements, “the variety of foods we are able to eat is limited by a lack of money,” had the highest proportion of participants responding “often” or “sometimes” (35.8%). Moderately food insecure children exhibited higher fat and saturated fat intakes, consuming 3.0 (0.2, 5.8) g/day more fat, and 2.0 (0.6, 3.5) g/day more saturated fat compared to food secure children (p&lt;0.05). Severely food insecure children had lower g/kg/day protein intake compared to food secure children (p&lt;0.05). In comparison to food secure children, moderately and severely food insecure children had lower fibre intake, consuming 1.6 (2.8, 0.3) g/day and 2.6 (4.0, 1.2) g/day less fibre, respectively. Severely food insecure children had the highest prevalence of inadequate calcium (7.0%) and vitamin C (9.3%) intakes, compared with food secure children [prevalence of inadequate intakes: calcium (2.3%) and vitamin C (2.8%)]. Household food insecurity was more common in those of Māori or Pacific ethnicity; living in areas of high deprivation; having a caregiver who was younger, not in paid employment, or had low educational attainment; living with ≥2 other children in the household; and living in a sole-parent household. Food insecure young NZ children consume a diet that exhibits lower nutritional quality in certain measures compared to their food-secure counterparts. Food insecurity was associated with various sociodemographic factors that are closely linked with poverty or low income. As such, there is an urgent need for poverty mitigation initiatives to safeguard vulnerable young children from the adverse consequences of food insecurity.

Contribution of Beef to Key Nutrient Intakes and Nutrient Adequacy in Pregnant and Lactating Women: NHANES 2011-2018 Analysis.

Beef is an important source of high-quality protein and several micronutrients, including iron, zinc, and B-vitamins. The objective was to assess the association of beef intake with nutrient intake and adequacy among pregnant and lactating women using 24-h dietary recall data. Usual intakes from foods were determined with the National Cancer Institute (NCI) method and % population below Estimated Average Requirement (EAR) or above Adequate Intake (AI) were estimated. A high proportion of pregnant and lactating women had inadequate intakes for vitamin D (94%), vitamin E (82%), vitamin C (52%), and vitamin A (50%), magnesium (35%), folate (31%), zinc (25%), and vitamin B6 (22%); only 4% and 35% met AI for choline and potassium, respectively. About 67% of pregnant and lactating women were beef consumers, consuming 49 g beef/day. Beef consumers had higher intakes (p < 0.05) of energy, protein, calcium, iron, phosphorus, selenium, sodium, zinc, thiamin, riboflavin, and niacin, and a higher proportion (p < 0.05) met nutrient recommendations for protein, calcium, iron, zinc, thiamin, riboflavin, niacin, vitamin B6, and vitamin B12 compared to non-consumers. In conclusion, pregnant and lactating women generally have inadequate nutrient intakes from their diets. Beef consumers have higher intakes and adequacy for certain nutrients, many of which are inherently available in beef or in foods eaten with beef.

Understanding Maternal Nutrition Insights from Pregnant Women in Bamenda, Cameroon

The foundation for good physical health is good nutritional status. Nutritional status of pregnant women is directly affected by the foods they eat and their nutrient content. Nutritional knowledge is positively associated with diet quality. The aim of this study was to assess nutritional status and nutrition education knowledge of pregnant women attending antenatal clinics in Bamenda Health District (BHD). &#x0D; Study Design: This study was carried conducted in BHD in the North West Region of Cameroon, with pregnant women aged 13 to 49 years recruited from public hospitals.&#x0D; Place and Duration of Study: BHD including (Bamenda Regional Hospital, Azire Integrated Health centre, Atuakom Integrated Health Centre, Ntambag Integrated Health Centre) between April 2022 to September 2022.&#x0D; Methodology: This was a cross sectional study carried out in four health facilities BHD. Random sampling technique was done to target the sample size of 354 pregnant women. A questionnaire was developed to collect socio-demographic information and clinical records of the pregnant women. Anthropometric parameters, biochemical and dietary assessments of the women were determined using standard techniques. Data collected was analysed by MS excel and SPSS Statistics version 20.0. Results were considered at significance level P ≤ 0.05. &#x0D; Results: The mean age of the study population was 26.4±5.5years and the average intake of servings of meals per day was suboptimal in the consumption of vegetables (2±1.9), fruits (0.6± 1.3) and milk (0.4 ±0.6) food groups. Women consumed diets that met less than 50% of energy needs. There exists a significant difference in mean energy requirements 1828.8 ± 152.9 Kcal compared to mean energy intake 1192.0 ± 344.6 Kcal which is below the Recommended Daily Allowances (RDA) of 2400 kcal for pregnant women. Ignorance still existed in dietary knowledge and 18.1% of the women were anaemic. &#x0D; Conclusion: There was an overall suboptimal approach to dietary intake among the pregnant women, inadequate food intake, poor food choices and limited healthy dietary knowledge. Thus pregnant women in BHD still need more access to information on dietary information.

An Affordable and Sustainable Thrifty-Like Meal Plan, FoodRx, That Meets the Recommended Dietary Allowances.

There is considerable controversy as to whether a healthy diet is affordable given recent inflation. In order to determine whether a healthy, climate-friendly sustainable diet can be obtained within the allotments of the Supplemental Nutrition Assistance Program (SNAP), we created and purchased 26weeks of meal plans designed to meet the EAT-Lancet sustainability guidelines and > 90% of the RDAs for 23 macro/micronutrients for households with at least 2 adults and 1-3 children. We compared the food quantities and cost of a healthy sustainable diet purchased in Los Angeles, 2023, to the Thrifty Food Plan, 2021. We compared the volume of food and cost of basic groceries to those recommended in the Thrifty Food Plan, 2021. The costs of the sustainable diet fell within the 2023 SNAP allotments as long as the average calories required per person did not exceed 2000. The volume of fruits, vegetables, legumes, nuts, and seeds were considerably higher for the sustainable diet compared to the Thrifty Food Plan. Given that calorie needs are the determinants of food quantity and costs, the USDA may consider offering supplemental coverage for individuals with higher calorie needs to make healthy eating affordable.

Association between dietary magnesium intake and muscle mass among hypertensive population: evidence from the National Health and Nutrition Examination Survey

BackgroundMagnesium is critical for musculoskeletal health. Hypertensive patients are at high risk for magnesium deficiency and muscle loss. This study aimed to explore the association between magnesium intake and muscle mass in patients with hypertension.MethodsIn this population-based cross-sectional study, 10,279 U.S. hypertensive adults aged 20 years or older were derived from the National Health and Nutrition Examination Survey in 1999–2006 and 2011–2018. Magnesium (Mg) intake from diet and supplements was assessed using 24-hour diet recalls. Muscle mass was evaluated by appendicular skeletal muscle mass index (ASMI, total ASM in kilograms [kg] divided by square of height in meters [m2]). The association of Mg intake with ASMI was estimated using weighted multivariable-adjusted linear regression models and restricted cubic splines.ResultsDose-response analyses showed a positive linear correlation between dietary Mg intake and ASMI. Every additional 100 mg/day in dietary Mg was associated with 0.04 kg/m2 (95% confidence interval [CI] 0.02–0.06 kg/m2) higher ASMI. The ASMI in participants who met the recommended dietary allowance (RDA) for dietary Mg was 0.10 kg/m2 (95% CI 0.04–0.16 kg/m2) higher than those whose dietary Mg was below estimated average requirement (EAR). However, the relationship of Mg intake from supplements with ASMI was not identified.ConclusionHigher level of dietary Mg intake rather than Mg supplements was associated with more muscle mass in U.S. adults with hypertension, which highlights the importance of meeting the recommended levels for dietary Mg intake.

Dietary zinc intake and absolute lymphocyte counts in advanced stage of nasopharyngeal cancer patients

BackgroundNasopharyngeal Cancer (NPC) patients experience a deficiency immune system due to a systemic inflammatory response. Anorexia due to inflammation and dysphagia, as well as the effects of therapy such as chemotherapy and radiotherapy in NPC, causes a decreased intake of macronutrients and micronutrients, including zinc. Long-term zinc deficiency affects both non-specific and specific immune components (lymphocytes, monocytes, macrophages, neutrophils). However, research regarding zinc intake and lymphocyte counts is still rarely carried out, especially in NPC patients in Indonesia. The population of Indonesia has a different dietary intake pattern from the population of western countries. Therefore, researchers intend to examine zinc intake and lymphocyte counts in NPC patients at Dr. Kariadi Hospital in Semarang, Indonesia. AimsTo determine the relationship between dietary zinc intake and Absolute Lymphocyte Counts (ALC) in NPC patients. MethodsThis study was a cross-sectional study involving NPC patients undergoing first to third cycles of chemotherapy and aged 18–59 years at Dr Kariadi Semarang in July 2020–October 2022. Patients with hypoalbuminemia, experienced metastases, had other comorbid diseases, and had undergone radiotherapy were excluded from this study. Dietary zinc intake was measured using the Food Frequency Questionnaire (FFQ) for the last 14 days and ALC was measured using a heme analyzer at Dr Kariadi Hospital Laboratory. Statistical analysis used the Pearson and Spearman correlation test to measure the strength of the correlation between dietary zinc intake and ALC, and a one sample T test to determine whether participants' zinc intake differed from the Recommended Dietary Allowance (RDA). ResultsThe sample of this research was 35 subjects [20 male subjects (57.1%) and 15 female subjects (42.1%)]. The average dietary zinc intake of NPC patients undergoing chemotherapy at Dr Kariadi Hospital was 5.18 ± 2.19 mg/day (5.83 ± 1.63 mg/day and 4.32 ± 2.58 mg/day for males and females, respectively). The results showed a positive correlation between dietary zinc intake and ALC in NPC patients (r = 0.41, p = 0.013; p < 0.05). ALC in NPC patients was influenced by zinc intake and protein intake (p < 0.05), but not energy intake, BMI, and age (p > 0.05). The zinc intake of men and women was significantly different compared to the RDA recommendation (p < 0.05). ConclusionThere is a significant and positive correlation between dietary zinc intake and absolute lymphocyte counts in NPC patients undergoing chemotherapy.
