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 26 weeks 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.

Adequacy of the "pocket formulas" for measuring total energy expenditure in healthy women compared with the new DRI equation: A doubly labeled water study.

OBJECTIVES: "Pocket formulas" are practical alternatives for calculating an individual's total energy expenditure (TEE). Typically, more sophisticated predictive equations are used, such as the new equations proposed in the Dietary Reference Intakes (DRI). Nevertheless, these new equations necessitate estimating physical activity levels (PALs). The aim of this study was to compare the use of pocket formulas (kcal/kg of body weight) with the new predictive equations for energy expenditure proposed by the DRI (2023) in healthy women and with the doubly labeled water (DLW) method to predict TEE. METHODS: The TEEs of healthy adult women were measured by DLW and calculated using the pocket formulas (× 20, × 25, × 30, and × 35 kcal/kg of body weight) and the new DRI equation. PALs by triaxial accelerometers were also collected. RESULTS: The study included 55 women. For the entire sample, the × 30 pocket formula had the lowest bias (-6%; limits of agreement [LOAs]: -39.8; 27.5; root mean square error: 373.4) and the highest precision (42%). The pocket formulas showed reasonable agreement in the different body mass index categories compared with the results found by the 2023 DRI proposal. For individuals with normal weight, the agreement was × 35 kcal/kg: bias (%) = -4.8; LoA = -41.5; 31.8, with overweight, it was × 30 kcal/kg: bias (%) = -2.2; LoA = -25.1; 20.6, and with obesity, it was × 30 kcal/kg: bias (%) = 4.2; LoA = -21.1; 29.4. CONCLUSION: Pocket formulas provide a reasonable agreement with TEE in healthy, sedentary, or low-active adult women, which may be a more simplistic strategy when there is no PAL data for calculating the DRI equations.

Nitrogen Balance at the Recommended Dietary Allowance for Protein in Minimally Active Male Vegans.

Vegan diets have gained popularity in recent years for reasons including health benefits and concerns for animal welfare. Although these diets are considered to be nutritionally adequate, questions remain over whether the current protein recommendation (0.8 g/kg/d) is sufficient. Protein status is determined through a nitrogen balance analysis when the protein content of the diet is known. A negative balance indicates a catabolic state, and a positive nitrogen balance indicates an anabolic state. In healthy adults, nitrogen equilibrium is the expectation reflecting the net synthesis and breakdown of proteins. Currently, there are no known studies measuring nitrogen balance in strict vegan men fed the protein requirement. Eighteen minimally active vegan men received a 5-day eucaloric diet (protein content: 0.8 g/kg/d). On day five, 24 h urine was collected for nitrogen analysis. Both the mean absolute nitrogen balance (-1.38 ± 1.22 g/d) and the mean relative nitrogen balance (-18.60 ± 16.96 mg/kg/d) were significantly lower than zero (equilibrium) (p < 0.001). There were no correlations seen between nitrogen balance and age, years as vegan, or fat-free mass. Consuming 0.8 g/kg/d of protein is not adequate to produce nitrogen balance in men adhering to typical strict vegan diets for at least one year.

Foundational Nutrition: Implications for Human Health.

Human nutrition, and what can be considered "ideal" nutrition, is a complex, multi-faceted topic which many researchers and practitioners deliberate. While some attest that basic human nutrition is relatively understood, it is undeniable that a global nutritional problem persists. Many countries struggle with malnutrition or caloric deficits, while others encounter difficulties with caloric overconsumption and micronutrient deficiencies. A multitude of factors contribute to this global problem. Limitations to the current scope of the recommended daily allowances (RDAs) and dietary reference intakes (DRIs), changes in soil quality, and reductions in nutrient density are just a few of these factors. In this article, we propose a new, working approach towards human nutrition designated "Foundational Nutrition". This nutritional lens combines a whole food approach in conjunction with micronutrients and other nutrients critical for optimal human health with special consideration given to the human gut microbiome and overall gut health. Together, this a synergistic approach which addresses vital components in nutrition that enhances the bioavailability of nutrients and to potentiate a bioactive effect.

Dietary Energy and Nutrient Intake of Healthy Pre-School Children in Hungary.

Diet in the early years of life may influence the development of chronic diseases later on. The aim of the present study was to investigate the dietary intake of 2- to 6-year-old Hungarian children. In 2013 and subsequently in 2016, cross-sectional surveys were conducted among parents of healthy children attending kindergarten in Hungary. We used a three-day food diary to record quantitative data of all the nutrients consumed by the children on two working days and one weekend day. The dietary intakes were compared to both the Hungarian recommended dietary allowances and the European Food Safety Authority recommendations. The nutritional data of altogether 186 children in 2013 and 556 children in 2016 were analyzed. The total energy and carbohydrate intake was appropriate. We observed high sugar intake in every fifth child. Protein, fat and cholesterol intake, as well as the intake of sodium, potassium and phosphorus, were high. The consumption of calcium and vitamin D was low. Water consumption was not satisfying. The present results underline the need for interventions starting early in life in order to ameliorate nutrient intake during childhood, possibly impacting long-term health outcomes.

Use of granules and free salts for Fe and Zn fortification of leafy vegetables: Improvements in trace element bioaccessibility and fulfillment of Dietary Reference Intakes.

BACKGROUND: Leafy vegetables represent an excellent dietary source of trace elements such as Fe and Zn. Nevertheless, Fe and Zn bioaccessibility can lessen due to a high concentration of anti-nutritional compounds. The encapsulation of Fe and Zn salts as granules could be used to fortify these leafy vegetables. METHOD: Three leafy vegetables, spinach, Swiss chard and Ethiopian mustard were fortified with iron sulfate and zinc sulfate as granules and free salts in order to test the improvements in the bioaccessibility and fulfillments of DRIs. Fe and Zn granules were prepared in a fluidized bed granulator. A probabilistic analysis was performed, using experimental data, to assess bioaccessible intake and fulfillments of DRIs in European populations. RESULTS: Fe contents ranged between 4.8 mg/100 g of Ethiopian mustard to 157.4 mg/100 g of spinach. Fe and Zn bioaccessibility percentages were low for Swiss chard and spinach without fortification. Fortification with granules improved Fe bioaccessibility of these latter vegetables (196 and 223 mg/100 g). Zn contents in samples without fortification ranged between 2.3 mg/100 g for Ethiopian mustard and 7.4 mg/100 g for spinach. Zn fortification as granules improved Zn bioaccessibility for the three vegetables studied. Thus, Zn bioccessible concentrations ranged between 17.4 and 108 mg/100 g for the solubility assay and between 5.9 and 31.1 mg/100 g for the dialyzability assay. Besides, the probability analysis showed that fortification had a better performance in meeting DRIs for those populations with higher consumption levels of leafy vegetables. CONCLUSIONS: The probability analysis demonstrated that fortification can be a suitable strategy to meet DRIs for both trace elements, which was especially remarkable for Fe. Fortification with granule was more effective in most the cases, although for Ethiopian mustard, free salt of Fe showed a better performance.

Adverse Effects on the Thyroid of Chinese Pregnant Women Exposed to Long-Term Iodine Excess: Optimal and Safe Tolerable Upper Intake Levels of Iodine.

Ensuring optimal iodine nutrition in pregnant women is a global public health concern. However, there is no direct data on safe tolerable upper intake levels (ULs) for pregnant women. A cross-sectional study was performed to determine the ULs of pregnant women. A total of 744 pregnant women were enrolled in this study. The median (IQR) urinary iodine concentration (UIC) in pregnant women was 150.2 (87.6, 268.0) µg/L, and the urinary iodine excretion (UIE) over 24 h was 204.2 (116.0, 387.0) µg/day. Compared with those with a UIE figure of between 150-250 µg/day, the reference group, the prevalence of thyroid dysfunction was 5.7 times higher (95%CI: 1.7, 19.2) in pregnant women with a UIE figure of between 450-550 µg/day, and 3.9 times higher (95%CI: 1.5, 10.3) in pregnant women with a UIE figure of ≥550 µg/day. Compared with an estimated iodine intake (EII) of between 100-200 µg/day, the reference group, the prevalence of thyroid dysfunction was 4.3 times higher (95%CI: 1.3, 14.4) in pregnant women with a UIE figure of between 500-600 µg/day, and 3.6 times higher (95%CI: 1.5, 8.9) in pregnant women with UIE of ≥600 µg/day. In general, our cross-sectional study found that excessive iodine intake during pregnancy appears to directly increase the risk of thyroid dysfunction. Avoiding chronic iodine intakes of 500 µg/day or higher or having a UIE figure of ≥450 µg/day is recommended for pregnant women in China.

Re-exploration of dietary iodine intake in Chinese adult males using a modified iodine balance study.

There is still controversy about optimal dietary iodine intake as the Universal Salt Iodization policy enforcement in China. A modified iodine balance study was thus conducted to explore the suitable iodine intake in Chinese adult males using the iodine overflow hypothesis. In this study, thirty-eight apparently healthy males (19·1 (sd 0·6) years) were recruited and provided with designed diets. After the 14-d iodine depletion, daily iodine intake gradually increased in the 30-d iodine supplementation, consisting of six stages and each of 5 d. All foods and excreta (urine, faeces) were collected to examine daily iodine intake, iodine excretion and the changes of iodine increment in relation to those values at stage 1. The dose-response associations of iodine intake increment with excretion increment were fitted by the mixed effects models, as well as with retention increment. Daily iodine intake and excretion were 16·3 and 54·3 µg/d at stage 1, and iodine intake increment increased from 11·2 µg/d at stage 2 to 118·0 µg/d at stage 6, while excretion increment elevated from 21·5 to 95·0 µg/d. A zero iodine balance was dynamically achieved as 48·0 µg/d of iodine intake. The estimated average requirement and recommended nutrient intake were severally 48·0 and 67·2 µg/d, which could be corresponded to a daily iodine intake of 0·74 and 1·04 µg/kg per d. The results of our study indicate that roughly half of current iodine intakes recommendation could be enough in Chinese adult males, which would be beneficial for the revision of dietary reference intakes.

The Urinary Excretion of Magnesium as an Effective Magnesium Deficiency State Indicator: A Controlled Intervention Trial.

With the western influence in our diets, food consumption has changed, and our magnesium (Mg) intake is no longer optimal. Serum Mg (S-Mg) level is currently used as an indicator of Mg deficiency and is strictly regulated via compensatory mechanisms. It is believed that a 24-h urine collection can be used to evaluate potential Mg deficiency. This study aimed to assess whether Mg deficiency state as found in urine Mg (U-Mg) excretion and improving such deficiency with a diet that meets the Recommended Dietary Allowances (RDAs) of Mg for 15 d. Healthy Japanese women were recruited for Study 1 (n=22) and Study 2 (n=10). Study 1 was 1-d balance test, where fasting blood and 24-h urine samples were collected. Study 2 was 15-d diet load test, where fasting blood (days 1, 7, and 15) and 24-h urine (odd days) were collected. All test meals were made certain to have met the RDA for Mg for women in their 20s. In Studies 1 and 2, S-Mg was within the normal range. In Study 1, U-Mg excretion was 67.7±17.0 mg/d, with a large dispersion. In Study 2, U-Mg excretion on days 7 and 15 was significantly higher than on day 1, but have no significant differences in U-Mg excretion between days 7-15. U-Mg excretion can be a valuable indicator to evaluate Mg state. In young women, improvements in Mg deficient state were observed after 7-15 d of taking meals that met the RDAs of Mg.

The Effect of a Vegan Diet on the Coverage of the Recommended Dietary Allowance (RDA) for Iodine among People from Poland.

The aim of this research was to estimate the effect of a vegan diet on the Recommended Dietary Allowance (RDA) coverage for iodine in people from Poland. It was hypothesized that the problem of iodine deficiency is a concern, especially among vegans. The survey study was conducted in the years 2021-2022 on 2200 people aged 18-80 with omnivore and vegan diets. The exclusion criteria in the study were pregnancy and lactation. The study found that the coverage of RDA for iodine among people with a vegan diet was lower than among people with an omnivore diet (p < 0.05); 90% of the participants with a vegan diet had an iodine intake below 150 µg/day. Plant-based dairy and meat analogs were consumed by vegans frequently and in large portions, but none were fortified with iodine. It was found that iodized salt was each group's primary source of iodine. However, it was observed that the iodine supply from this source was limited among vegans, especially in female subjects, who consumed less salt and smaller portions of meals. That is why consideration should be given to the iodine fortification of plant-based foods commonly consumed by vegans.

Does Aging Affect Vitamin C Status Relative to Intake? Findings from NHANES 2017-2018.

The aging population is growing and fueling a global increase in chronic diseases and healthcare expenditure. In this study, we examine vitamin C dose-concentration relationships based on data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 to identify a possible age-dependent change in intake vs. concentration relationship among non-supplemented individuals (n = 2828). The vitamin C intake was similar between the younger (18-36 years), middle (37-58 years) and older (59-80+ years) age groups; however, circulating vitamin C concentrations were significantly lower in the middle and older age groups (p < 0.001). For intakes above 75 mg/day, no significant difference in the intake vs. serum concentration relationship was identified between younger and older individuals. However, for intakes below 75 mg/day, we found significantly lower serum concentrations relative to intake for the older compared to younger individuals, despite smoking being more prevalent in the younger compared to older adults (p < 0.001). This effect persisted among non-smokers and was further exacerbated by smoking in older people. Collectively, the present study suggests that healthy aging in non-institutionalized individuals does not increase requirements for vitamin C. In contrast, the lower serum concentrations relative to intake observed in older individuals at intakes < 75 mg/day may suggest that older individuals are more sensitive to a low vitamin C intake, perhaps due to the increased impact of long-term smoking and increased chronic disease prevalence in older adults. This finding may have implications for future intake guidelines in countries with low RDAs and for WHO/FAO, but requires further investigation.

Amino Acid Intake and Conformance With the Dietary Reference Intakes in the United States: Analysis of the National Health and Nutrition Examination Survey, 2001-2018.

BACKGROUND: The lack of complete amino acid composition data in food composition databases has made determining population-wide amino acid intake difficult. OBJECTIVES: This cross-sectional study characterizes habitual intakes of each amino acid and adherence to dietary requirements for each essential amino acid (EAA) in the US population. METHODS: Food and Nutrient Database for Dietary Studies ingredient codes with missing amino acid composition data were matched to similar ingredients with available data so that amino acid composition could be determined for 100% of foods reported in the dietary intake assessment component of NHANES. Amino acid intakes during NHANES 2001-2018 (n = 72,831; ≥2 y) were calculated as relative (mg·kg of ideal body weight-1·d-1) intakes. Data from NHANES 2011-2018 were used to determine the percentage of population consuming less than that recommended by the DRIs for each EAA by age, sex, and race/ethnicity. RESULTS: Relative intakes of EAAs and NEAAs were greatest in those 2-3 y and lowest in older individuals (≥71 y or ≥80 y). In females aged 2-18 y, relative intakes of EAAs were lowest in non-Hispanic White (NHW; histidine, lysine, threonine, methionine, and cysteine) and non-Hispanic Black (NHB; valine, isoleucine, leucine, phenylalanine, tryptophan, and tyrosine) populations and highest in the Asian population. In females aged ≥19 y, relative intakes were lowest in NHW (lysine and methionine only) and NHB populations and highest in the Asian population. In males aged 2-18 y, relative intakes of EAAs were lowest in the NHB population and highest in the Asian population. In males ≥19 y, relative intakes were lowest in NHB and NHW (lysine only) populations and highest in the Hispanic population. Less than 1% of individuals aged ≥19 y did not meet the Estimated Average Requirements for each EAA. CONCLUSIONS: EAA intakes in the US population exceed recommended minimum population requirements. Future studies can use the method described here to quantify amino acid intake and examine relationships with health and disease.

Composition of Common Junk Food Items and Their Contribution to the Dietary Requirement of Children and Adolescents.

OBJECTIVE: To estimate the carbohydrate, energy, fat, protein, and sodium content of commonly consumed junk food items and to compare these to the Recommended Dietary Allowance (RDA) and Estimated Average Requirements (EAR) of children. METHODS: A list of eight common junk food categories was made, and the median nutritional content of carbohydrate, energy, fat, protein and sodium was determined from the commonly consumed brands in these categories. It was compared to the RDA and EAR for two different age groups viz., age 4-6 year, and male adolescents aged 13-15 years. RESULTS: The junk food groups with the highest carbo-hydrate were packaged potato chips and cakes, the group with the highest fat content was packaged potato chips, and the groups with the highest salt content were burgers and packaged potato chips. The %EAR of one packet of some items was 80-90% of daily fat requirement, and more than 60% of daily sodium requirement. CONCLUSIONS: Junk foods contribute substantially to the daily intake of carbohydrates, free sugars, total fats, saturated fats, and sodium of children.

Potential Contribution to Dietary Reference Intake (DRI) of Agar Extracted from Gelidium latifolium (Gelidiaceae, Rhodophyta) as a Mineral Source.

Ca, Na, Mg, K, P, Fe, Zn, Mn, V, Cr, Ni, Cu, Mo, and Se were determined in agar obtained seasonally from Gelidium latifolium in coast of Black Sea, using the inductively coupled plasma mass spectroscopy. Also, the potential contribution of the agar to the dietary reference intakes (DRIs) was evaluated according to the Basic Nutritional Requirements Guideline released by the Institute of Medicine and the Official Journal of the European Union. The results show that agar extracted from G. latifolium could be used as a food supplement to help meet the DRIs of certain essential minerals and trace elements. In the study, the most dominant macro and micro elements were found to be potassium (K), calcium (Ca), sodium (Na), iron (Fe), and manganese (Mn), respectively. The Na/K ratio of the agar obtained seasonally was found to be below the maximum limits recommended by international organizations (Na/K ≤ 0.6). The Ca/Mg ratio was calculated between 1.44 and 1.55 throughout the year. The Ca/Mg and K/Na ratios were not reflected highly significant difference between seasons. Ion quotient values for extracted agar were between 0.36 and 40.54, so they can reduce hypertension, preeclampsia, and heart disease in human beings. Accordingly, extracted agar from G. latifolium red seaweed were of high quality and safety and might be used in the field of nutrition.

Dietary Intakes From Ad Libitum Consumption of Canadian Armed Forces Field Rations Compared With Usual Home Dietary Intakes and Military Dietary Reference Intakes.

INTRODUCTION: Diet has an impact on weight status, health, and physical performance. Assessing the usual at-home dietary intakes of military personnel can help ascertain their nutritional status before field training or operations. Preference for foods consumed on a routine basis can also impact the military's preference for and consumption of field rations. Military personnel are limited by the inherent nature of the field rations and availability of calories and food types; and despite previous studies indicating a high acceptability of the field rations, it is unknown whether military personnel self-select the same number of calories when faced with a restricted list of field ration options as they would from their usual foods. Although field rations are intended to be nutritionally sufficient for standard military operations, there are limited data on the ad libitum intake of nutrients of Canadian Armed Forces (CAF) personnel from field rations in comparison to the military dietary reference intake (MDRI) recommendations, which establishes standards intended to meet the nutritional requirements of military personnel on duty. Thus, assessing the adequacy of their usual diets at home and longer-term sustenance on field rations in relation to MDRIs can provide insight on CAF personnel's operational readiness. The objectives of this study were to describe and compare, in a convenience sample of CAF, their ad libitum nutrient intakes from the consumption of self-selected field rations at home with their usual home intakes and to compare both with MDRI recommendations. MATERIALS AND METHODS: Eighteen CAF participants weighed and recorded their dietary intake from the ad libitum consumption of field rations at home and their usual at-home diets. Both MDRIs and the Institute of Medicine's dietary reference intake recommendations were used to assess the adequacy of intakes for each individual. Paired Student's t-test or Wilcoxon-matched paired tests were used to compare nutrient intake levels between usual at-home diets and field rations consumed at home. RESULTS: Mean daily energy intakes were similar between ad libitum intakes from field rations (2,688 ± 619 kcal) and usual home diets (2,657 ± 580 kcal), although participants had significantly higher intakes of protein and fat from their home diets and higher intakes of carbohydrates from the field rations (P ≤ 0.05). Participants had less than the recommended intakes of some micronutrients (vitamins A and D, folate, calcium, magnesium, and potassium), from both their home diets and field rations, but adequate intakes of vitamin C and iron. CONCLUSIONS: The results of this study showed no difference in energy intake between the consumption of field rations and home diets, with levels consistent with recommendations for individuals with average physical activity levels. The results also demonstrated less than the recommended intakes (in comparison with MDRIs) of some nutrients from both home diets and self-selected consumption of field rations, warranting further research into nutritional adequacy for operational readiness.

Health and nutrition beyond essential nutrients: The evolution of the bioactives concept for human health.

Our food supply contains a range of essential and non-essential food components. There are substantial epidemiologic findings and additional clinical data to support the health benefits for some non-essential food components - these compounds are often referred to as bioactives. While there is a well-established process in place to make science-based dietary recommendations for essential nutrients, this is not the case for bioactive food components. This manuscript reviews the evolution of the RDAs and the transition to a DRI framework for establishing requirements for essential nutrients. Then, the potential of development of public health recommendations for bioactives will be explored and the benefits and challenges of making recommendations will be presented. The scientific support for case studies for lutein and flavan-3-ols, will be made. Finally, suggestions for frameworks that might be considered by authoritative policy-making bodies when evaluating the efficacy and safely of proposed bioactives will be discussed.

Analysis of muscle fatigue recovery in skiers: a nutritional intervention / Análise na recuperação da fadiga muscular em esquiadores: intervenção nutricional / Análisis en la recuperación de la fatiga muscular en esquiadores: intervención nutricional

ABSTRACT Introduction: Skiing is a sport that demands the high performance of motor coordination with high energy consumption, factors that strongly influence muscle fatigue. Athletes who experience this phenomenon tend to present a decline in performance, generating psychological irritability and impairment in concentration. Diet is closely related to athletic performance, but the proper prescription for skiing athletes still lacks studies. Objective: To explore the methods of recovery from sports fatigue in skiers by providing up-to-date perspectives for effective nutritional intervention during the recovery stage. Methods: Seven young male skiers were selected as research subjects, and caloric intake, among other conditions, was recorded in detail. After three weeks, indices of body weight, body fat rate, serum metabolism, cardiopulmonary capacity, and energy metabolism, among other relevant information, were duly recorded and compared. Results: The intervention did not significantly impact lean body mass indices (p>0.05). The athletes' body weight decreased significantly, and the body fat rate decreased significantly after the nutritional intervention; The analyzed biomarkers were positively impacted, except the urea nitrogen concentration that showed a tendency to increase after the nutritional intervention, an effect that may be linked to the proportional increase of protein intake. Conclusion: The proposed nutritional intervention positively impacted the skiers' energy metabolism, directly impacting the athletes' recovery from sports fatigue.

RESUMO Introdução: O esqui é um esporte que exige alto desempenho de coordenação motora com um elevado consumo de energia, fatores que influenciam fortemente a fadiga muscular. Atletas que experienciam esse fenômeno, tendem a apresentar um declínio no nível do desempenho, gerando irritabilidade psicológica e prejuízos na concentração. A dieta está intimamente relacionada ao desempenho atlético, porém a receita adequada para os atletas em esqui ainda carece de estudos. Objetivo: Explorar os métodos de recuperação da fadiga esportiva nos esquiadores fornecendo perspectivas atualizadas para uma intervenção nutricional eficaz durante a etapa de recuperação. Métodos: Sete jovens esquiadores do sexo masculino foram selecionados como sujeitos da pesquisa, e a ingestão calórica, entre outras condições foram detalhadamente registradas. Após três semanas, índices de peso corporal, taxa de gordura corporal, metabolismo sérico, capacidade cardiopulmonar, metabolismo energético, entre outras informações relevantes foram devidamente registradas e comparadas. Resultados: A intervenção não impactou significativamente nos índices de massa magra corporal (p>0,05). O peso corporal dos atletas diminuiu significativamente e a taxa de gordura corporal diminuiu significativamente após a intervenção nutricional; os biomarcadores analisados foram positivamente impactados, a exceção da concentração de nitrogênio ureico que apresentou tendência de alta após a intervenção nutricional, efeito que pode estar atrelado ao aumento proporcional da ingesta proteica. Conclusão: A proposta de intervenção nutricional apresentou impactos positivos no metabolismo energético dos esquiadores, impactando diretamente na recuperação da fadiga esportiva dos atletas. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

Receitas padronizadas da alimentação escolar indígena de Mato Grosso do Sul / Recettes normalisées de l'alimentation scolaire indigène du Mato Grosso do Sul

Diante das dificuldades em padronizar fichas técnicas de preparações culinárias por parte dos profissionais atuantes na alimentação escolar, o CECANE/UFMS se propôs em realizar a elaboração de um receituário padrão. Tal documento tem o objetivo de auxiliar no planejamento, organização e execução do preparo das refeições nas escolas, de modo que este receituário se constitua como um instrumento de auxílio para melhor execução do PNAE nas escolas indígenas. Acompanhando o cenário nacional, a população indígena de Mato Grosso do Sul vem sofrendo com a insegurança alimentar e nutricional devido à carência de ingestão de proteínas, vitaminas e minerais, ocasionada pela redução do consumo de alimentos in natura e pelo aumento da oferta e acesso a alimentos industrializados com alto teor de açúcares, gorduras e aditivos alimentares. Essa situação é causada pela mudança dos hábitos alimentares ocasionada pela influência da população não-indígena, pela diminuição das terras indígenas, mudanças climáticas e escassez de alimentos (CHAMORRO; COMBÈS, 2015). Nesse contexto, o suporte governamental manifesto por meio da implantação de programas sociais e políticas públicas de alimentação e nutrição são ferramentas de extrema importância para combate à fome, garantia do direito à alimentação adequada e saudável, assim como a manutenção das tradições indígenas (CHAMORRO; COMBÈS, 2015). Dentre as ferramentas governamentais existentes para promover a Segurança Alimentar e Nutricional (SAN) no âmbito escolar, o PNAE desponta como um programa federal bem consolidado que viabiliza recursos financeiros para a alimentação dos estudantes e para ações de Educação Alimentar e Nutricional (EAN) nas comunidades (BRASIL, 2020). Os ditos materiais desenvolvidos pelo CECANE/UFMS visam tratar de temas tais quais o acesso aos alimentos de forma igualitária, bem como apoiar o desenvolvimento sustentável por meio do incentivo à compra de diferentes gêneros alimentícios produzidos pela agricultura familiar e pelos empreendedores familiares rurais, principalmente aqueles das comunidades tradicionais indígenas e quilombolas. Como disposto na legislação em relação aos cardápios escolares, seu planejamento e execução devem ser feitos pelo Responsável Técnico (RT) do PNAE, priorizandose a utilização de alimentos in natura ou minimamente processados, respeitando as necessidades nutricionais das respectivas faixas etárias, os hábitos alimentares locais, e atendendo às especificidades culturais das comunidades tradicionais, além de defender a sustentabilidade, sazonalidade e diversidade agrícola da região (BRASIL, 2020).
