Dietary Intake of Vitamin D from Dairy Products Reduces the Risk of Osteoporosis.

Abstract: Background: Vitamin D and calcium are important dietary compounds that affect bone mass, even if other minerals (potassium, zinc, etc.) and vitamins (A, C and K) are also involved. Vitamin D and certain minerals, in fact, play an important role in calcium homeostasis and calcium absorption. Hip fracture incidence is higher in Europe and the United States, where calcium is frequently included in the human diet; while the occurrence of these fractures is lower in developing countries, where diets are often poor in calcium. This condition is named the “calcium paradox”, and may be partially explained by phosphate toxicity, which can negatively affect mineral metabolism. It is important to maintain correct dietary calcium-phosphate balance in order to have a healthy life, reducing the risk of osteoporotic fractures in older people. Vitamin D can also act as a hormone; vitamin D2 (ergocalciferol) is derived from the UV-B radiation of ergosterol, the natural vitamin D precursor detected in plants, fungi, and invertebrates. Vitamin D3 (cholecalciferol) is synthesized by sunlight exposure from 7-dehydrocholesterol, a precursor of cholesterol that can also act as provitamin D3. Dietary intake of vitamin D3 is essential when the skin is exposed for short periods to ultraviolet B light (UV-B), a category of invisible light rays such as UV-A and UV-C. This can be considered the usual situation in northern latitudes during the winter season, or the typical lifestyle for older people and/or for people with very white delicate skin. The actual recommended daily intake of dietary vitamin D is strictly correlated with age, ranging from 5 μg for infants, children, teenagers, and adults—including pregnant and lactating women—to 15 μg for people over 65 years.

Vitamin K2 Needs an RDI Separate from Vitamin K1.

Abstract: Vitamin K and its essential role in coagulation (vitamin K [Koagulation]) have been well established and accepted the world over. Many countries have a Recommended Daily Intake (RDI) for vitamin K based on early research, and its necessary role in the activation of vitamin K-dependent coagulation proteins is known. In the past few decades, the role of vitamin K-dependent proteins in processes beyond coagulation has been discovered. Various isoforms of vitamin K have been identified, and vitamin K2 specifically has been highlighted for its long half-life and extrahepatic activity, whereas the dietary form vitamin K1 has a shorter half-life. In this review, we highlight the specific activity of vitamin K2 based upon proposed frameworks necessary for a bioactive substance to be recommended for an RDI. Vitamin K2 meets all these criteria and should be considered for a specific dietary recommendation intake.

Protein intake adequacy among Nigerian infants, children, adolescents and women and protein quality of commonly consumed foods.

Abstract: Protein is important for growth, maintenance and protection of the body. Both adequacy of protein quantity and protein quality in the diet are important to guarantee obtaining all the essential amino acids. Protein-energy malnutrition is widely present in developing countries such as Nigeria and might result in stunting and wasting. Needs for protein differ depending on age and physiological status and are higher during growth, pregnancy and lactation. The present review assessed protein quantity and quality in diets of Nigerian infants, children, adolescents, and pregnant and lactating women. Literature reviews and calculations were performed to assess adequacy of Nigerian protein intake and to examine the Nigerian diet. The digestible indispensable amino acid score was used to calculate protein quality of nine Nigerian staple foods and of a mixture of foods. The Nigerian population had mostly adequate protein intake when compared with the most recent protein recommendations by the FAO (2013) and WHO/FAO/UNU (2007). An important exception was the protein intake of adolescent girls and pregnant and lactating women. Most of the assessed Nigerian plant-based staple foods were of low protein quality and predominantly lacked the amino acid lysine. The addition of animal-source foods can bridge the protein quality gap created by predominance of plant-based foods in the Nigerian diet. The methodology of this review can be applied to other low- and middle-income countries where diets are often plant-based and lack variety, which might influence protein intake adequacy.

Protein Intake to Maximize Whole-Body Anabolism during Postexercise Recovery in Resistance-Trained Men with High Habitual Intakes is Severalfold Greater than the Current Recommended Dietary Allowance.

Abstract: Background Dietary protein supports resistance exercise-induced anabolism primarily via the stimulation of protein synthesis rates. The indicator amino acid oxidation (IAAO) technique provides a noninvasive estimate of the protein intake that maximizes whole-body protein synthesis rates and net protein balance. Objective We utilized IAAO to determine the maximal anabolic response to postexercise protein ingestion in resistance-trained men. Methods Seven resistance-trained men (mean ± SD age 24 ± 3 y; weight 80 ± 9 kg; 11 ± 5% body fat; habitual protein intake 2.3 ± 0.6 g·kg-1·d-1) performed a bout of whole-body resistance exercise prior to ingesting hourly mixed meals, which provided a variable amount of protein (0.20-3.00 g·kg-1·d-1) as crystalline amino acids modeled after egg protein. Steady-state protein kinetics were modeled with oral l-[1-13C]-phenylalanine. Breath and urine samples were taken at isotopic steady state to determine phenylalanine flux (PheRa), phenylalanine excretion (F13CO2; reciprocal of protein synthesis), and net balance (protein synthesis - PheRa). Total amino acid oxidation was estimated from the ratio of urinary urea and creatinine. Results Mixed model biphasic linear regression revealed a plateau in F13CO2 (mean: 2.00; 95% CI: 1.62, 2.38 g protein·kg-1·d-1) (r2 = 0.64; P ˂ 0.01) and in net balance (mean: 2.01; 95% CI: 1.44, 2.57 g protein·kg-1·d-1) (r2 = 0.63; P ˂ 0.01). Ratios of urinary urea and creatinine concentrations increased linearly (r = 0.84; P ˂ 0.01) across the range of protein intakes. Conclusions A breakpoint protein intake of ∼2.0 g·kg-1·d-1, which maximized whole-body anabolism in resistance-trained men after exercise, is greater than previous IAAO-derived estimates for nonexercising men and is at the upper range of current general protein recommendations for athletes. The capacity to enhance whole-body net balance may be greater than previously suggested to maximize muscle protein synthesis in resistance-trained athletes accustomed to a high habitual protein intake. This trial was registered at clinicaltrials.gov as NCT03696264.

Nutrition to Prevent or Treat Cognitive Impairment in Older Adults: A GRADE Recommendation

Abstract: Aging is associated with cognitive declines leading to mild cognitive impairments or Alzheimer disease. Nutrition appear to protect from aging. Some dietary factors could either increase or protect against cognitive declines. This article aimed to provide GRADE recommendations related to nutrition aspects able to prevent or to treat cognitive impairments. A comprehensive literature review was performed using Medline database. The GRADE approach was used to classify quality of the existing evidence (systematic review or meta-analysis).The GRADE process led us to formulate seven key nutritional recommendations to manage cognitive declines, but did not allow us to do it for protein, vitamin B or antioxidants. Thus, 1) adherence to a Mediterranean diet (GRADE 1B); 2) high-level of consumption of mono- or poly- unsaturated fatty acids combined to a low consumption of saturated fatty acids (GRADE 1B); 3) high consumption of fruits and vegetables (GRADE 1B); 4) higher vitamin D intake (GRADE 1C) than the recommended daily allowance. In addition, a ketogenic diet, a low consumption of whole-fat dairy products or a caloric restriction are promising nutritional habits although the evidence does not yet support widespread uptake (GRADE 2C). In conclusion, nutrition is an important modifiable factor to prevent or protect against cognitive decline. Nevertheless, more studies are required to determine specific guidelines such as duration and amounts of nutrients to help older adult to maintain a healthy cognitive life.

Application of nutrient essentiality criteria to dietary carbohydrates.

Abstract: The purpose of the present review is to describe how human physiology at very low carbohydrate intakes relates to the criteria for nutritional essentiality. Although we did not limit ourselves to one particular type or function of carbohydrates, we did primarily focus on glucose utilisation as that function was used to determine the recommended daily allowance. In the general population, the human body is able to endogenously synthesise carbohydrates, and does not show signs of deficiency in the absence of dietary carbohydrates. However, in certain genetic defects, such as glycogen storage disease type I, absence of dietary carbohydrates causes abnormalities that are resolved with dietary supplementation of carbohydrates. Therefore, dietary carbohydrates may be defined as conditionally essential nutrients because they are nutrients that are not required in the diet for the general population but are required for specific subpopulations. Ketosis may be considered a physiological normal state due to its occurrence in infants in addition to at very low carbohydrate intakes. Although sources of dietary carbohydrates can provide beneficial micronutrients, no signs of micronutrient deficiencies have been reported in clinical trials of low-carbohydrate ketogenic diets. Nonetheless, more research is needed on how micronutrient requirements can change depending on the dietary and metabolic context. More research is also needed on the role of dietary fibre during a low-carbohydrate ketogenic diet as the beneficial effects of dietary fibre were determined on a standard diet and several studies have shown beneficial effects of decreasing non-digestible carbohydrates.

Maternal dietary selenium intake is associated with increased gestational length and decreased risk of preterm delivery.

Abstract: The first positive genome-wide association study on gestational length and preterm delivery showed associations with a gene involved in the selenium metabolism. In this study we examine the associations between maternal intake of selenium and selenium status with gestational length and preterm delivery in 72,025 women with singleton live births from the population based, prospective Norwegian Mother, Father and Child Cohort Study (MoBa). A self-reported, semi-quantitativ food-frequency questionnaire answered in pregnancy week 22 was used to estimate selenium intake during the first half of pregnancy. Associations were analysed with adjusted linear and cox regressions. Selenium status was assessed in whole blood collected in gestational week 17 (n=2,637). Median dietary selenium intake was 53 (IQR: 44-62) μg/day, supplements provided additionally 50 (30-75) μg/day for supplement-users (n=23,409). Maternal dietary selenium intake was significantly associated with prolonged gestational length (β per SD=0.25, 95% CI=0.07-0.43) and decreased risk for preterm delivery (n=3,618, HR per SD=0.92, 95% CI=0.87-0.98). Neither selenium intake from supplements nor maternal blood selenium status was associated with gestational length or preterm delivery. Hence, this study showed that maternal dietary selenium intake, but not intake of selenium containing supplements, during the first half of pregnancy was significantly associated with decreased risk for preterm delivery. Further investigations, preferably in the form of a large RCT, are needed to elucidate the impact of selenium on pregnancy duration.

A Novel Dietary Intervention Reduces Circulatory Branched-Chain Amino Acids by 50%: A Pilot Study of Relevance for Obesity and Diabetes.

Abstract: Elevated circulating branched-chain amino acids (BCAAs; isoleucine, leucine, and valine) are associated with obesity and type 2 diabetes (T2D). Reducing circulatory BCAAs by dietary restriction was suggested to mitigate these risks in rodent models, but this is a challenging paradigm to deliver in humans. We aimed to design and assess the feasibility of a diet aimed at reducing circulating BCAA concentrations in humans, while maintaining energy balance and overall energy/protein intake. Twelve healthy individuals were assigned to either a 7-day BCAA-restricted diet or a 7-day control diet. Diets were iso-nitrogenous and iso-caloric, with only BCAA levels differing between the two. The BCAA-restricted diet significantly reduced circulating BCAA concentrations by ~50% i.e., baseline 437 ± 60 to 217 ± 40 µmol/L (p < 0.005). Individually, both valine (245 ± 33 to 105 ± 23 µmol/L; p < 0.0001), and leucine (130 ± 20 to 75 ± 13 µmol/L; p < 0.05), decreased significantly in response to the BCAA-restricted diet. The BCAA-restricted diet marginally lowered Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) levels: baseline 1.5 ± 0.2 to 1.0 ± 0.1; (p = 0.096). We successfully lowered circulating BCAAs by 50% while maintaining iso-nitrogenous, iso-caloric dietary intakes, and while meeting the recommended daily allowances (RDA) for protein requirements. The present pilot study represents a novel dietary means by which to reduce BCAA, and as such, provides a blueprint for a potential dietary therapeutic in obesity/diabetes.

Dietary Practices, Nutrient Adequacy, and Nutrition Status among Adolescents in Boarding High Schools in the Kilimanjaro Region, Tanzania.

Abstract: A cross-sectional study was conducted to assess dietary practices, nutrient adequacy, and nutrition status among 164 adolescents aged between 16 and 19 years in boarding secondary schools in the Kilimanjaro region. In-depth interviews and a survey guided by a semistructured and structured questionnaire, including 24-hour recall and food frequency questionnaire techniques, were used to collect information. Nutrition status was assessed using anthropometric measurements and hemoglobin levels. WHO AnthroPlus software and NutriSurvey software were used to analyze anthropometry and dietary data, respectively. Diet in boarding schools was monotonous comprising mainly of cereal-legume meal with low intake of animal sources, fruits, and vegetables. Mean intake of energy, vitamin C, iron, calcium, and zinc was 1392 kcal, 24.8 mg, 9.2 mg, 134.5 mg, and 4.3 mg, respectively, which were below the Recommended Daily Allowance. The average carbohydrate, fat, and protein intake of 471.9 g, 73.7 g, and 80.7 g, respectively, were slightly higher than the Recommended Daily Allowance in both sexes. Male had a significantly higher intake of protein and carbohydrates ( ). Female had a significantly ( ) high intake of fat compared to male adolescents. Overall, 23.1% of the adolescents were anaemic, 25% were overweight, and 6.1% were obese. Boarding secondary schools’ diet is monotonous and are inadequate in key micronutrients, iron, zinc, calcium, and vitamin C. There is a coexistence of undernutrition and overnutrition among adolescents in boarding schools. Therefore, monitoring adolescents’ dietary intake and nutrition status is a key in preventing adolescents’ malnutrition in the short term and diet-related diseases in the long term.

Mineral Content of Food Supplements of Plant Origin, by Energy Dispersive X-ray Fluorescence: A Risk Assessment

Abstract: The aim of this study is to evaluate the elemental composition of six food supplements of plant origin, commonly sold in the Portuguese market, by energy dispersive X-ray fluorescence. The presence of arsenic in all the Maca, Ashwagandha, Camu-Camu and Hemp protein samples (except the generic form) is a reason of concern due to the long-term effects of As mainly in its inorganic form. Thus, great caution must be taken on some food supplements, particularly the cases of Moringa from Egypt and Yellow/Xpresso Maca, whose inorganic As concentrations are in line with the upper bound concentration for the 95th dietary exposure according to the European Food Safety Authority which is 0.64 μg/kg bw/day. In what regards Hemp protein, if the supplier’s daily intake recommendation (30 g) is followed, values as high as 1.75 μg/kg bw/day of inorganic As will be consumed, which are dangerously above the upper bound. In this case this specific supplement lot should be removed from the market. Also the consumption of Hemp protein leads to a daily intake of Mn above the Daily Reference Intake (DRI) and Adequate Intakes (AIs) for adults. The contamination of Goji berries by Pb is a reason for concern—organic berries contained 11.3 μg/g while berries derived from conventional agriculture 11.6 μg/g, leading to daily intake doses of 315.3 μg and 324.8 μg, respectively, if the recommended daily intake of 28 g is followed. Our findings point out to an inadequacy of the recommended intakes by the supplier vis a vis the concentrations observed, greatly increasing the risk for public health.

Energy and Macronutrients Intakes among Childbearing Age Women Living in the Urban Area of Morocco: A Cross-Sectional Study.

Abstract: Over the last few decades, there have been significant dietary and lifestyle changes worldwide. In Morocco, these changes have led to serious nutritional disorders and increased risk of morbidity and mortality particularly among vulnerable groups such as women of childbearing age. We aimed to assess the average daily energy and macronutrient intakes and to investigate their association with socioeconomic factors and weight status among women aged 19–49 years in urban areas. A total of 542 women attending public health centers were recruited. Socioeconomic and demographic data were collected using a questionnaire. Anthropometric measurements were taken using standardized equipment. Food consumption data were obtained through the 24-hour dietary recall method, and the macronutrient composition of foods was estimated based on the Moroccan food composition table and the Nutrilog software. The average daily energy intake among the study population was 1591 kcal, composed of 56% from carbohydrates, 28% from fats, and 16% from protein. Reported energy intake by the majority of women (81.5%) was lower than recommended daily allowances for energy. There was a significant positive correlation between educational level and energy ( ), carbohydrates ( ), proteins ( ), and fats intakes ( ), respectively. A significant negative association of household size with protein intakes was also observed ( ). Carbohydrates, proteins, and fats intakes tended to decrease; however, these associations were not statistically significant. Further studies and appropriate interventions are needed to address the trends in energy and macronutrients intakes in the development of policy initiatives aimed at nutrition education and chronic disease prevention among childbearing age women.

Effects of phosphorus and calcium to phosphorus consumption ratio on mineral metabolism and cardiometabolic health.

Abstract: Phosphorus is a common additive used in food processing that is typically consumed in excess of the recommended daily allowance; however, our knowledge of its effects on health, in the context of normal renal function, is limited. Unlike phosphorus, calcium intake is generally less than recommended, and it has been hypothesized that the calcium to phosphorus ratio may be partly responsible for the proposed negative health consequences. Therefore, this study sought to determine the effects of increased phosphorus additive intake, in the context of high calcium consumption, on endocrine markers of mineral metabolism and cardiometabolic health. An outpatient feeding study was performed in which healthy adults were fed a run-in control diet for 2 weeks followed by a phosphorus additive enhanced diet with supplemental calcium to an approximate ratio of 1 (experimental diet) for 2 weeks. Blood and urine samples were collected, and participants had brachial flow-mediated dilatation measured, with analyses comparing follow-up measures to baseline. Two weeks of experimental diet increased serum fibroblast growth factor 23 concentrations but lowered body weight and serum leptin; however, other phosphorus responsive factors such as osteopontin and osteocalcin did not increase. A complementary study in male mice also demonstrated that the regulation of known dietary phosphorus responsive factors was mostly abrogated when dietary calcium was raised in parallel with phosphorus. In conclusion, the study identifies weight, leptin and insulin as responsive to dietary phosphorus and that certain aspects of the systemic phosphorus response are attenuated by a corresponding high calcium intake.

Relevance of Calcium and Vitamin D in Supporting Bone Health: An Expert Panel Recommendation in Indonesia

Abstract: Osteoporosis is a bone health related condition that weakens the bones, making individuals fragile and prone to breaks. Nutrients such as calcium and vitamin D are essential for bone health. Calcium helps in building and maintaining bone mass while vitamin D aids in the absorption and utilization of calcium. According to WHO, 28.8% men and 32.3% women in Indonesia have osteoporosis, and this is inspite of the international recommendations for the daily intake of calcium and vitamin D intake. This could be attributed to low community awareness on how to prevent and care for osteoporosis. Several high-risk population groups have been identified such as those with osteopenia, undergoing rehabilitation and pregnancy/lactation periods. Therefore, in this review, an expert panel comprising of specialties of dietetics, rehabilitation medicine, orthopaedic, obstetrics & gynaecology, pharmacology, and geriatrics, convened to provide an evidence-based guidance on the prevention and care for osteoporosis. The recommendations are as follows: (i) It is important to know that calcium and vitamin D work synergistically to maintain bone health. (ii) The intake of calcium and vitamin D must start early. (iii) We should be aware that our diet and lifestyle today does not allow us to meet the recommended daily intake of calcium and vitamin D required for optimal bone health. (iv) Supplementation can compensate for the deficits in both calcium and vitamin D intake, thereby strengthening bone health. This study could guide the primary health care team, who plays a critical role in community care, to encourage early bone health awareness and care in Indonesia.

Nutritional Quality of Fast Food Kids Meals and Their Contribution to the Diets of School-Aged Children.

Abstract: International data indicate that children and adolescents obtain around one third of their daily food intake from products consumed outside their home. Food products from restaurants are usually higher in calories and lower in nutritional value than those prepared home. We evaluated the nutritional quality in kids’ meals from three fast food chains and two movie theaters and compared them with nutritional recommendations for Mexican school-age population. Results showed that the menu options marketed for school-age children have higher caloric contributions than those recommended, in addition to a deficient nutritional quality. The contribution of caloric and of almost all macronutrients for all mealtimes is not only high but even above 100% or 200% of the mean recommended daily intake (reaching to more than 400% of the recommendations of carbohydrates and lipids of preschool age group). In particular, the snack main dish (popcorn), provides over 100% of the mean energy intake recommendations for the three school age groups and for preschool age group, this contribution could reach to 270%. Therefore, regulations regarding nutritional recommendations should exist for these types of commercialized food products for school-age children, along with mandatory and clear labeling that allows consumers to be able to make better choices for their kids.

A Primary Care Provider's Guide to Diet and Nutrition After Spinal Cord Injury.

Abstract: Physiological changes that occur after spinal cord injury (SCI) are profound and affect almost every organ system in the human body. Energy balance is significantly altered due to motor paralysis, spasticity or flaccidity, neurogenic sarcopenia, neurogenic osteopenia, sympathetic nervous system disruption, and blunted anabolism. Energy expenditure is markedly reduced, whereas hypothalamic control of appetite and satiety is diminished, resulting in discordant energy intake. Ultimately, neurogenic obesity ensues as the result of a positive energy balance. Even though nutritional guidelines for persons with SCI have been available since 2009, the necessity for body composition assessment and total daily energy expenditure was insufficiently addressed such that most individuals with SCI continued in positive energy balance despite "adherence" to the guidelines. Macronutrients must be carefully assessed to optimize caloric intake, while micronutrient consumption may need to be supplemented in order to meet recommended daily allowances. Such a diet would emphasize foods with low caloric yet high nutrient density. This article reviews current literature regarding nutritional requirements for SCI and provides a straightforward plan for implementing more rigorous dietary interventions meant to address the obesity crisis in this especially vulnerable population.

Vitamins and minerals

This chapter details the properties, biological importance, and means of loss for each vitamin. The benefits and concerns related to vitamin supplementation are also included. Foods that are a significant source of each vitamin and their recommended daily intake value are provided. This chapter also describes 14 minerals that are important to health. Information regarding their biological importance, recommendations for daily intake, and supplementation is included.

Can Cereal Products Be an Essential Source of Ca, Mg and K in the Deficient Diets of Poles?

Abstract: The studies aimed to evaluate the significance of cereal products as an essential source of Ca, Mg and K in the diets of Poles. The study covered 226 groups of cereal products most popular in Poland: bread, bread rolls, cooked pasta, cooked grains and cooked rice. The content of Ca, Mg and K was determined by means of FAAS. In addition, considering the recommended daily intake of K, Ca and Mg for the Polish population of adults, the percentage share of respective products in daily supply of these minerals was determined. The content of the above-mentioned minerals in all analysed cereal products can be presented as K > Mg > Ca. Intake of cereal products covers the requirement of K, Mg and Ca among adult Poles, respectively, in ca. 9%, ca. 12 (men)–15 (women) % and ca. 3%. The best source of K, Mg and Ca is bread which in the daily diets of Poles supplies more than 90% of minerals consumed with cereal products. It can be claimed that cereal products are a poor source of Ca, but they supply significant amounts of K and Mg in the diets of Poles, especially given that deficiency of such minerals is common in Poland. It would be important to consider obligatory fortification of flour with minerals which are deficient in the diets of Poles.

Female Collegiate Dancers Body Composition, Macronutrient and Micronutrient Intake Over Two Academic Years: A Longitudinal Analysis.

Abstract: Collegiate dancers face unique challenges to maintain a lean aesthetic, optimal diet, and a high-performance level due to the various stressors in college. The purpose of this study was to examine changes in body composition (BC) and diet over two years. Participants (N = 17, 19.6 ± 1.6 years) completed two laboratory sessions per semester. Sessions included height and weight, BC, dietary intake, and a health history questionnaire. Regardless of rigorous dance training and variations in the academic calendar, no significant changes in BC or diet were observed within semesters of over two years. BMI was normal (24.9 ± 4.1 kg/m2) with fat mass exceeding 30% at all timepoints. Fat mass was negatively correlated with carbohydrate, fat, and protein intake (g/kg/day; r = −0.291, p = 0.004; r = −0.372, p < 0.0001; r = −0.398, p < 0.0001; respectively). Energy intake was within the recommended daily allowance (2040 ± 710 kcal/day), however may be insufficient for an active dance population. Protein (1.1 ± 0.5 g/kg), carbohydrate (3.7 ± 1.6 g/kg), calcium (835 ± 405 mg/day), iron (17 ± 15 mg/day), and potassium (1628 ± 1736 mg/day) intake fell below recommendations for an active population. Alterations in dance training and the demands of the academic calendar may be contributing to suboptimal dietary intake and BC in female collegiate dancers.

Dietary carbohydrate intake in patients with type 2 diabetes mellitus and diabetes control: a cross-sectional study.

Abstract: Background Food intake has important implications for patients with type 2 diabetes. Objective Similarly, in other crop species, this observational study aimed to assess dietary carbohydrate (CHO) and non-starch polysaccharide (NSP) intake and examine their association with glycemic control among Saudi patients with type 2 diabetes mellitus (T2DM). Design We investigated dietary intake in 404 patients (207 males and 197 females) with T2DM between November 2018 and March 2019. Dietary intake was assessed by face-to-face interviews using a validated dietary questionnaire. Results The results revealed that dietary CHO intake (67% of energy) exceeded the recommended daily intake, and white rice (Basmati rice) was the major contributor to CHO intake. However, the dietary NSP intake was lower than recommended, and it was negatively associated with HbA1c levels. Conclusion This cross-sectional study showed that dietary CHO intake was high among Saudi patients with type 2 diabetes, and that their daily intake of NSPs was correlated with a lower level of HbA1c. Dietary advice should be given for patients with diabetes to reduce their intake of starchy food such as rice.

Prevalence of inadequate intake of folate after mandatory fortification: results from the first National Dietary Survey in Brazil.

Abstract: Our aim was to estimate the prevalence of folate inadequacy (POFI) according to life stage, socio-economic status, and geographical regions after the mandatory fortification of wheat and maize flour in Brazil. This was a population-based study. Data from two non-consecutive food records from the National Dietary Survey/Household Budget Survey 2008–2009 were used to estimate the usual dietary folate intake in µg dietary folate equivalents (DFEs). The National Cancer Institute method was used to account for within-person variance and the Estimated Average Requirement (EAR) cut-point method was used to calculate the POFI. The survey included 32,749 individuals, 15,700 males and 17,049 females, over 10 years old. Pregnant women, lactating women, and individuals with unreliable energy intake data were excluded. Overall POFI was 31.5% and mean dietary folate intake was 411.1 µg DFE. The lowest POFI occurred in the youngest age group of 10–13 years in both sexes, while the highest POFI was observed in the group ≥ 71 years. In women of childbearing age, POFI was around 32%. The lowest income strata had the highest POFI. The most developed regions (South and Southeast) had the lowest POFI compared to less developed regions. Our data show that folate inadequacy is still prevalent in Brazil mainly in low-income groups and less developed regions. Actions need to be taken to ensure that women of childbearing age, who presented a high prevalence of inadequate folate intake, achieve the recommended daily intake of 400 µg DFEs.

Dietary Behaviors That Place Young Adults at Risk for Future Osteoporosis.

Abstract: Dietary behaviors during adolescence and emerging adulthood have important consequences for peak bone mass (PBM) attainment This study aimed to examine dietary factors that are either beneficial or detrimental to bone health and determine the major sources of calcium in the diets of a sample of young adults A cross-sectional survey was conducted among 189 Australians aged 18–30 years Three-day dietary intakes were collected using consecutive 24 h recall interviews Daily totals for energy and nutrients and serves for food groups were computed The proportion contribution of calcium (mg) from different food groups as well as calcium (mg) per portion and per 100 g were calculated Females and males failed to meet the recommendations for dairy (91%, 82%), fruit (89%, 94%) and vegetables (74%, 86%) Eighty percent were above the recommended daily intake range for sodium For calcium, 53% of females and 48% of males had intakes below the estimated average requirement (EAR) Milk products and dishes made the highest mean calcium contribution per portion (mg) mean standard deviation (SD), 204 mg (212) and accounted for 30% of calcium intake in females and 35% in males As young adulthood is the final chance for dietary manipulation before PBM is achieved, these dietary risk factors should be addressed

Sodium and Potassium Intake in Residents of Retirement Homes.

Abstract: Excessive salt intake and its impact on health is a public health problem in many regions of the world. The currently estimated dietary intake of salt among free-living adults is well above the WHO recommendations. Over the years, the number of residents in retirement homes has increased. Besides this, the nutrition of elderly people may be affected by physiological changes that occur with aging. The question is whether residents of retirement homes receive a more balanced diet, or whether the trend of excessive salt consumption continues even among institutionalised elderly people. Salt and potassium intake were assessed by measuring sodium and potassium excretion over 24 h in urine collected from a sample of residents of three retirement homes in the Goriska region, Slovenia. The average salt intake was 8.3 (2.9) g/day, which was significantly higher (p < 0.001) in men than in women (10.1 (3.1) vs. 7.3 (2.2) g/day, respectively). The estimated total daily potassium intake was 2.6 (0.6) g/day in men and 2.0 (0.8) g/day in women (mean 2.2 (0.8) g/day). The ratio of sodium to potassium was 1.53 (0.48). The salt intake among residents of retirement homes in the Goriska region, especially in men, exceeds the WHO recommended daily intake of <5 g. The mean daily potassium intake was below the WHO recommendations of 3.5 g/day.

[Vitaminology: from molecular aspects to improving technology of vitamin status children and adults].

Abstract: A statistical analysis of the data on the sufficiency with vitamins of certain groups of the Russian adults and children from 1987 to 2017 revealed certain patterns. At first, the presence of multiple micronutrient deficiency (vitamins D, B group, as well as a number of minerals) is still a characteristic feature. At second, vitamin D deficit is the most common. At third, the decrease in the frequency of detection of B vitamin deficiency was inhibited and it still persists in a significant number of examined individuals (median detection frequency is 41%). Vitamin C, A and E deficiency is rarely found among healthy adults. The literature analysis and rat model studies show that the performance of each vitamin depends on the saturation of the organism with other vitamins. Sufficient provision of the body with all vitamins is a necessary condition for the implementation of many functions of vitamin D, the functions of B vitamins are inextricably linked. A diet composed of traditional products does not allow reaching the optimal supply of the body with vitamins and minerals. Everyday using of fortified foods or vitamin-mineral supplements (VMS) is an effective way to eliminate the micronutrient deficiency in the nutrition of the population. The theoretical basis for the development of VMS, intended for different groups of the population, includes the study of the initial vitamin-mineral status, features of work and physical activity, taking into account the role of the lack of individual vitamins in the development of the pathological process and the drug therapy used, individual characteristics of metabolism, in particular due to gene polymorphism. VMS with optimal composition should include vitamin D and all vitamins of B group. The doses of vitamins should be significant, comparable with the recommended daily intake. Additional biomedical requirements for the composition of VMS are formed taking into account the characteristics of the diet. The dose of the antioxidant vitamins and mineral substances should be increased in order to mitigate the effect of dietary fiber with adsorbing properties or polyunsaturated fatty acids that are susceptible to peroxidation and reduce antioxidant status of the organism. VMS with increased doses of all vitamins are intended for the quick and effective elimination of micronutrient deficiency. The total daily intake of micronutrients should not be excessive.

Children's Multivitamin/Mineral Supplements: Label Claims and Measured Content Compared to Recommended Dietary Allowances and Tolerable Upper Intake Levels

Abstract: US children ages 4 and older use multivitamin/mineral supplements (MVMs) formulated to meet the Daily Values for adults. To better evaluate the potential for nutrient adequacy and excess, it is helpful to determine actual ingredient content instead of amounts declared on labels. We tested children's MVMs and compared the products’ labeled and measured contents with Recommended Dietary Allowances (RDA) and Upper Tolerable Intake Levels (UL) established for children ages 4 to 8 years. Children's MVMs were defined as dietary supplements (DSs) containing three or more vitamins with or without minerals and other bioactive components labeled for individuals ages 4 and older. Nationally representative children's MVMs were identified based on relative market share estimates (RMSE) derived from frequency of use and respondents’ weights in infant/pediatric MVM subsets of 2003–2006 National Health and Nutrition Examination Surveys, and store surveys. The 21 top and 43 lower market share DSs selected for this study represented ∼72% of the total RMSE. The DSs were purchased in 2008 from multiple market channels in regions of AL, CA, MI, MO, NY, and OK identified using a multistage probability-proportional-to-size approach. Vitamin and mineral content was measured by commercial labs in 3 to 6 lots of 47 chewable tablets, 11 gummies, 4 liquids, 1 gumball, and 1 powder DS. For 13 of 16 nutrients (copper, iodine, iron, zinc, folic acid, niacin, riboflavin, thiamin, vitamins A, B-12, B-6, D and E), most MVMs were labeled at or above the RDA but below UL levels. For calcium, magnesium and phosphorus, all the studied DSs were labeled below the RDAs. The DSs that contained zinc, niacin and retinol labeled above their ULs had overall mean RMSEs comparable to the DSs labeled within the RDA-UL ranges. Overages resulted in levels exceeding the UL for folic acid in 24 out of 29 DSs labeled at the UL and for retinol in 10 out 40 DSs labeled below the UL, including one of the three most highly consumed MVMs. The prevalence of children's MVMs on the US market with labeled levels at or above the RDA, or at UL, combined with analytically verified overages, suggests risks of excess in intakes for zinc, niacin, retinol and folic acid, especially when MVM use is combined with diets containing many highly fortified foods.

Association of zinc intake & serum zinc levels with acne severity

Abstract: 96 Normal 0 false false false EN-US ZH-CN AR-SA Background: Recent studies have suggested the relationship between diet and acne, and zinc plays a role through its anti-inflammatory mechanism. This study aimed to determine the association between zinc intake and serum zinc levels with acne severity. Methods: A comparative cross-sectional study was conducted to assess the difference in zinc intake and serum zinc levels with acne severity based on Indonesian Acne Expert Meeting (IAEM) criteria. Sixty patients with acne in Dr. Cipto Mangunkusumo General Hospital were selected. The effect of zinc intake on acne severity was analyzed via unpaired T test, whereas the effect of serum zinc levels on acne severity was examined with Mann–Whitney test. Data were further evaluated using SPSS 20.0. Results: Zinc intake in all the subjects was below the Indonesian recommended daily allowance, and the mean of zinc intake and serum zinc levels in the mild acne group was higher than that of the moderate–severe acne group. The zinc intake significantly differed between the mild and moderate–severe acne groups (p < 0.01). Likewise, serum zinc levels significantly varied between mild and moderate–severe acne group (p = 0.048). Conclusion: Although this study showed a significant difference between zinc intake and serum zinc levels with the severity of acne vulgaris, further follow-up studies should be performed to assess zinc for acne vulgaris therapy. Keywords: zinc intake, serum zinc level, acne severity
