Nutritional perspectives in female soccer: a scoping review.

The purpose of the review was to evaluate the literature exploring nutritional habits and practices in female soccer players. The PRISMA-ScR Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews were followed. Searches of Web of Science, PubMed and Scopus databases were conducted for studies exploring the nutritional habits and practices of female soccer players. A total of 72 studies were included in the scoping review. Studies on female soccer players mainly focused on daily energy expenditure, daily energy and macronutrient intake and hydration status. A negative energy balance was consistent across studies, and the ingestion of CHO appears below the current recommendations. Female soccer players are predominately in negative energy balance, which may indicate that they are at risk of low energy availability. A high use of nutritional supplements is apparent in female soccer, whilst a large proportion of players commence training dehydrated. The current findings have implications for practitioners relating to the planning, management, monitoring, and implementation of nutritional intake and training and competition schedules.

Nutrients and Quality Aspects Characterizing Ostrea edulis Cultivated in Valli di Comacchio (Northern Italy) Across Different Seasons

The quality aspects of Ostrea edulis (O. edulis) cultured in Valli di Comacchio were examined across different seasons. Nutritional quality parameters, antioxidant activity, total carotenoids, and contaminants were determined in winter, summer, and autumn (December, June, and October). Seasonal variations in nutritional parameters were observed. In particular, in the winter samples, proteins, eicosapentaenoic acid, docosahexaenoic acid, threonine, tyrosine, valine and methionine, isoleucine, potassium, and carotenoids showed the highest values, whereas oleic acid, linolenic acid, lysine, and magnesium exhibited the maximum values in the summer. Finally, lipids, carbohydrates, histidine, and magnesium were present at high values in the autumn. The antioxidant activity values differed between the two methods used (DPPH and photochemiluminescence assays); however, the oysters collected in June presented lower antioxidant capacity. Contaminant levels were always below the imposed concentration limits; however, higher levels of toxic metals were detected in the winter, while polycyclic aromatic hydrocarbons were detected in the summer and autumn. It is important to monitor the nutritional and toxicological quality of Ostrea edulis throughout the cultivation seasons, not only to enhance knowledge of this species and improve its cultivation systems but also to determine the optimal period for human consumption from both nutritional and toxicological perspectives.

Socio-Demographic Influences on Dietary Habits and Nutritional Awareness: A Case Study of Polish Biathlon Association National Team Members.

This study investigated the influence of sociodemographic factors on the dietary habits of athletes of the Polish Biathlon Association. Focusing on age, education, employment status, and gender, this research assesses food choices, meal preparation, and nutritional awareness within a structured sports environment. A cross-sectional survey of 54 athletes was conducted using a modified "Eating Habits of Poles" questionnaire to explore food selection, preparation methods, consumption patterns, and nutritional perspectives. This focus on biathletes emphasizes their distinct dietary needs, which arise from the demanding combination of endurance and precision in their sport, providing valuable insights for tailored dietary strategies to enhance their performance and overall health. The results indicate that age, education, and employment status significantly influence Polish biathletes' dietary habits and nutritional awareness. Older athletes (under 23 years) demonstrated significantly higher nutritional awareness regarding modern dietary trends (p = 0.015). In contrast, 50% of higher-education athletes were more engaged in meal planning and healthier food choices than those with elementary education (p = 0.031). Employment status also played a role; 70% of the athletes were students who exhibited more convenience-based food choices, whereas 30% were employed and maintained more structured eating patterns (p = 0.008). Minimal gender differences were found, with 50% of male and 50% of female athletes showing similar dietary habits, likely due to standardized nutrition programs provided to all athletes. This indicates a potential need for further research to determine whether professional dietary support can effectively address typical gender-related variations in food behavior and lead to improvements in dietary outcomes. This study highlights the importance of targeted nutrition education and professional support for optimizing the nutritional habits of professional athletes. This emphasizes that socio-demographic factors such as age, education, and employment status significantly shape these behaviors, underscoring the need for personalized nutritional strategies within athletic programs.

Marine-Derived Bioactive Ingredients in Functional Foods for Aging: Nutritional and Therapeutic Perspectives.

Aging is closely linked to various health challenges, including cardiovascular disease, metabolic disorders, and neurodegenerative conditions. This study emphasizes the critical role of bioactive compounds derived from marine sources, such as antioxidants, omega-3 fatty acids, vitamins, minerals, and polysaccharides, in addressing oxidative stress, inflammation, and metabolic disorders closely related to aging. Incorporating these materials into functional foods not only provides essential nutrients but also delivers therapeutic effects, thereby promoting healthy aging and mitigating age-related diseases. The growth of the global anti-aging market, particularly in North America, Europe, and Asia, underscores the significance of this study. This review systematically analyzes the current research, identifying key bioactive compounds, their mechanisms of action, and their potential health benefits, thus highlighting the broad applicability of marine-derived bioactive compounds to enhancing healthy aging and improving the quality of life of aging populations.

Insights in Nutrition to Optimize Type 1 Diabetes Therapy.

Nutrition is an essential part of therapy for type 1 diabetes and is constantly evolving, offering growing opportunities to prevent this disease, slow down its evolution, and mitigate it. An attempt was made to bring together the current state of knowledge. In the path from the preclinical phase of the disease to its clinical onset, there is a phase known as the "honeymoon period" or partial remission, where different possible dietary options for combatting this disease have been presented. The most commonly used dietary models were compared, and the most frequent co-existing pathologies, such as overweight, non-alcoholic fatty liver disease, dyslipidemia, celiac disease, and metabolic instability, were addressed from their nutritional and dietary perspectives to provide clinicians with an updated framework of knowledge and support researchers in further investigations into the topic. Finally, a glimpse into the possible interplay between nutrition and the gut microbiome, food security, and ultra-processed food is provided. It is hoped that clinicians treating people with type 1 diabetes will be provided with further opportunities for the daily management of their patients through personalized nutrition.

Fruit and vegetables loss and waste in preschools belonging to the National Board of Kindergartens of Chile.

Food waste is a global issue affecting society from environmental, nutritional, and social perspectives. In collaboration with the National Board of Preschools, fruit and vegetable waste generated during the preparation of lunch was quantified in four preschools in the Metropolitan area of Santiago in Chile. This study was conducted in four preschools, two in the Western area of Santiago and two in the Eastern area, of which two hold environmental quality certifications. Over a five-day period, the weight of raw materials and waste from vegetables (peels) and fruit (pomace) were measured. Percentages of vegetable and fruit post-cleaning losses and waste were evaluated. Vegetable loss exceeded 20% in 31% of the preschools, primarily from carrots and potatoes. Fruit losses were higher, with pears accounting for the most significant waste, recorded in 75% of the study centers. No differences in vegetable loss was found between centers, while variations were observed for fruit. Preschools with environmental quality certifications wasted less onions (p = 0.016) but more pears (p = 0.036). There is higher fruit loss than vegetable loss, with onions and tomatoes being the least wasted. Possessing an environmental quality certification does not guarantee a significant reduction in overall losses. Handling and storage conditions may play a key role in minimizing losses. Further studies are needed to provide evidence that can guide improvements in Chile's National Board of Preschools services, aiming for a more sustainable lunch preparation processes.

Sustainability and nutritional composition of food offer and choices in three hospital canteens in Italy

Diet is considered one of the most important determinants of health and at the same time a cause of climate change. We conducted a cross-sectional study in three Italian hospital canteens on five consecutive working days to investigate food offer availability and user choices in terms of nutritional intake and environmental impact. Photos of lunch trays were collected by the researchers and food offer and choices were analysed using the Italian Food Composition Database for Epidemiological Studies and the SU-EATABLE LIFE dataset. A total of 1227 lunch meals were analysed. The median energy intake ranged from 646 to 900 kcal/tray. The median energy content from lipids ranged from 32 to 40 % of energy and exceeded that from carbohydrates in one canteen. The median carbon and water footprint ranged from 773 to 1338 g CO2 eq./tray and from 847 to 1229 L H2O/tray, respectively. Differences occurred depending on sex and typology of work. In conclusion, regardless of the differences in the number of food options offered in the three canteens, the choices tended to be suboptimal from a nutritional perspective. The most sustainable choices were made in the canteen without beef on offer. Measures should be taken to increase the variety of vegan and vegetarian options on offer and to improve food choices in terms of nutritional composition and environmental sustainability. This could be done through educational programmes focused on increasing awareness on their diet, and practical indications on how to compose a complete and low impact meal.

Ultra-processed vegan foods: Healthy alternatives to animal-source foods or avoidable junk?

Animal-source foods (ASFs), namely, meat, milk, eggs, and derived products, are crucial components of a well-balanced diet owing to their contribution with multiple essential nutrients. The benefits of the consumption of ASFs in terms of hedonic responses, emotional well-being, and mood are also widely documented. However, an increasing share of consumers decide to exclude ASFs from their diets. Some of these vegan consumers are inclined to consume so-called "meat" and/or "dairy analogs," which are produced from plant materials (soy, wheat, and oat, among others). In order to simulate appearance, texture, and flavor of ASFs, these industrial vegan foods are designed using an intricate formulation and industrial processing, which justifies their identification as ultraprocessed foods (UPFs). While the introduction of these processed vegan products is becoming popular in developed countries, the consequences of the sustained intake of these products on human health are mostly ignored. Contrarily to common belief, which emphasizes their role as "healthy" alternatives to ASFs, these plant-based UPFs may enclose certain threats, which are reviewed in the present paper. The remarkable differences between vegan UPFs and the genuine ASFs (meat/dairy products) from sensory, nutritional, hedonic, or health perspectives precludes the designation of the former as analogs of the latter. Understanding the basis of these differences would contribute to (i) providing consumers with grounds to make reasoned decisions to consume meat/dairy products and/or the vegan alternatives and (ii) providing food companies with strategies to produce more appealing, nutritive, and healthy industrially processed vegan products.

A comparison of animal and plant-based proteins from an economic, environmental, and nutritional perspective in the Republic of Ireland

CONTEXTProtein is a central component of health and nutrition. The current protein production system is unlikely to sustainably meet the growing global demand for protein. Therefore, alternative sources of protein must be considered. OBJECTIVEThis study uniquely compares animal-based (milk, beef meat, sheep meat) and plant-based (cereals and legumes) protein production in terms of land usage. The comparison is carried out across a suite of economic, environmental, and nutritional metrics. As land use decisions are taken at the farm level, the analysis adopts a farm gate approach. Focusing on the supply side, consumption is not considered in the analysis. METHODSEconomic performance is measured through the gross and net margins. Environmental performance is evaluated through farm-level greenhouse gas (GHG) emissions and nutrient (nitrogen and phosphorus) balances. Nutritional performance is measured through the gross protein yield, the protein yield corrected for digestibility and land-use efficiency, i.e., the land needed to generate one kg of (digestible) protein. Results are expressed per hectare and per 100 g of gross and digestible protein to allow for a holistic comparison. The analysis focuses on the Republic of Ireland, a relevant country given the importance of the strong agricultural export focus, the dominance of the livestock sector and the country's ambitious environmental emission reduction targets. RESULTS AND CONCLUSIONSFindings indicate that, on a per hectare basis, milk production on dairy farms has the strongest economic performance and highest GHG emissions amongst the products considered. Crops' gross and net margins are less than half that of dairy farms, but they also show the strongest environmental performance generally. Cereals and legumes have the best nutritional performance, from a protein perspective, whereas sheep meat production returned the lowest gross and digestible protein yields per hectare. Arable crops also show the lowest GHG emissions and nutrient balances on a per unit of protein basis. SIGNIFICANCELand-use policies need to be designed holistically, given the complexity of the agricultural sector. Agricultural policy design currently focuses on income support and on the environmental impact of the agricultural sector, but farmers' livelihood and food and protein security need to be safeguarded. Diversifying agricultural production and increasing plant-based protein production in Ireland, a country with a livestock-focused agricultural sector, could contribute to achieving the climate change targets of the country, provided the necessary policy levers are in place.

Nutrient Intakes in Prostate Cancer Survivors in the United States: A Nationally Representative Study

There are currently more than 3.3 million prostate cancer (PC) survivors in the United States. Conformance with national dietary guidelines and a good diet quality may lower the risk for Gleason grade progression in PC patients. Assessing the nutritional status of PC survivors is thus of paramount importance from a public health nutrition perspective. We used 24-h dietary recall data from the National Health and Nutrition Examination Surveys (NHANES) to systematically estimate nutrient intakes in n = 360 PC survivors (which may be extrapolated to represent n = 1,841,030 PC survivors) aged 70.69 years on average, and contrasted the results to the daily nutritional goals (DNG) in the 2020–2025 Dietary Guidelines for Americans (DGA). Diet quality in PC survivors was found to be generally poor, and the DNG as specified in the DGA were not met for many micronutrients, including calcium, magnesium and potassium. PC survivors had an insufficient intake of many vitamins (including vitamins A, C, D and E), and did not meet the intake recommendations for dietary fiber. Racial disparities in PC were reflected in the lower overall DQ in Non-Hispanic Black participants. Our results reiterate the need for nutritional assessment and counseling to improve DQ in PC patients.

Practical Guidelines by the Andalusian Group for Nutrition Reflection and Investigation (GARIN) on Nutritional Management of Patients with Chronic Obstructive Pulmonary Disease: A Review.

Malnutrition is common in chronic obstructive pulmonary disease (COPD) patients and is associated with worse lung function and greater severity. This review by the Andalusian Group for Nutrition Reflection and Investigation (GARIN) addresses the nutritional management of adult COPD patients, focusing on Morphofunctional Nutritional Assessment and intervention in clinical practice. A systematic literature search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, followed by critical appraisal based on Scottish Intercollegiate Guidelines Network (SIGN) guidelines. Recommendations were graded according to the European Society for Clinical Nutrition and Metabolism (ESPEN) system. The results were discussed among GARIN members, with consensus determined using a Likert scale. A total of 24 recommendations were made: 2(A), 6(B), 2(O), and 14(GPP). Consensus exceeded 90% for 17 recommendations and was 75-90% for 7. The care of COPD patients is approached from a nutritional perspective, emphasizing nutritional screening, morphofunctional assessment, and food intake in early disease stages. Nutritional interventions include dietary advice, recommendations on food group intake, and the impact of specialized nutritional treatment, particularly oral nutritional supplements. Other critical aspects, such as physical activity and quality of life, are also analyzed. These recommendations provide practical guidance for managing COPD patients nutritionally in clinical practice.

Postoperative Nutritional Assessment of Laparoscopic Versus Open Partial Hepatectomy.

No studies have investigated the advantage of laparoscopic hepatectomy (LH) compared with open hepatectomy (OH) from a nutritional perspective. This study aimed to compare the postoperative nutritional status between LH and OH. A total of 186 patients who underwent partial hepatic resection for liver tumors were analyzed retrospectively. We compared perioperative variables between LH and OH. The nutritional status was assessed using serum albumin (Alb) and rapid turnover protein concentrations. We investigated risk factors for postoperative malnutrition using univariate and multivariate analyses. The LH group, compared with the OH group, had a significantly shorter operative time (239 vs. 344 min, p<0.03), less intraoperative blood loss (100 vs. 343 g, p<0.01), and a shorter length of postoperative stay (8 vs. 11 days, p<0.01). Postoperative serum Alb and prealbumin concentrations in the LH group were significantly higher than those in the OH group (3.4 vs. 3.2 g/dl, p<0.01; 15.0 vs. 12.0 mg/dl, p=0.02, respectively). The multivariate analysis showed that OH (p=0.02) and hepatocellular carcinoma (p<0.01) were significant and independent risk factors for postoperative malnutrition. LH may be superior to OH in terms of the postoperative nutritional status, intraoperative blood loss, and length of postoperative stay.

The effect of Lactiplantibacillus plantarum fermentation and blanching on microbial population, nutrients, anti-nutrients and antioxidant properties of fresh and dried mature Moringa oleifera leaves

Moringa oleifera is an excellent source of nutrients and functional ingredients of human health significance. This study was conducted to determine the role of lactic acid fermentation and blanching in improving nutritional attributes and functional properties of M. oleifera leaves. Submerged lactic acid fermentation of M. oleifera was carried out for 24 h by using a Lactiplantibacillus plantarum strain. The results showed that fermentation resulted in a microbial population of M. oleifera leaves dominated with higher count of L. plantarum i.e., 4.06 log10 CFU/g after 24 h fermentation. L. plantarum count was reduced from 4.06 to 1.61 log10 CFU/g in fermented M.oleifera leaves powder after cabinet dehydration. Higher levels of protein (29.87 %), and fiber (32.26 %) were observed in fermented M. oleifera leaves while the levels of carbohydrates (10.74 %), fat (7.72 %), and energy (232.06 kcal) were lower than the levels observed in raw and blanched leaves. Lactic acid fermentation also anticipated reduction in anthocyanin (14.50–10.37 mg/100g), chlorophyll A (52.64–45.35 mg/100g), and lycopene (11.94–9.13 mg/100g) content of M. oleifera leaves. Fermentation significantly (p ≤ 0.05) increased level of total phenolic content i.e., 55.48 mg gallic acid equivalents (GAE)/g, total flavonoid contents i.e., 70.81 mg quercetin equivalent (QE)/g and flavonols i.e., 36.97 mg QE/g. Lactic acid fermentation reduced the levels of intrinsic nutrient inhibitors such as alkaloids (2.74–1.94 g/100g; 29 % ↓), saponins (3.80–2.98 g/100g: 20 % ↓), oxalates (2.43–1.85 g/100g; 24 % ↓), tannin (0.83–0.44 g/100g; 47 % ↓), and phytic acid (1.94–1.02 g/100g; 47 % ↓) compared with the raw leaves. The results suggest lactic acid fermentation is a cost-effective technique to improve nutritional and health perspectives of M. oleifera leaves.

Exploring Ayurvedic Nutritional Medicine Perspective: The Benefits and Clinical Significance of Millets

The science of nutrition may be enriched as well as deficiency and over nutritional disorders can be managed in a better way by incorporating Ayurvedic nutritional medicine measures in form of different diets and dietary regulation The millets are referred to in Ayurveda as Kudhanya, Kshudra Dhanya, and Trin Dhanya under the category Dhanya Varga (group of fried grains). Aim &amp; Objectives: To explore Ayurvedic nutritional medicine perspective and clinical significance of millets. Material and Methods: The research methodology used for the study comprises a review of relevant academic articles and Ayurvedic literature. Using the search engines Google Scholar, Scopus, Web of Science and PubMed (MEDLINE). Results: Millets are economical, nutritional and gluten free. Millets are best advised in Kaphaja Roga (diseases due to Kapha) and other Santarpanajanya Vyadhi (diseases brought on by over nutrition of one or more tissues). When it comes to Vataja Roga (diseases caused by Vata), millets should be avoided as they exacerbate the ailment. Conclusion: It has been stated in Ayurveda classics that being thin is preferable to being obese, and the Laghu (lightness), Lekhaniya (therapeutic scrapping) property of millets, with low glycemic content and the added benefit of long-term satiety, making it an excellent choice as a Ayurvedic Nutritional Medicine. Additionally, it is Ruksha (dry) with Lekhana (therapeutic scrapping) and Kledashoshana (dries up excess moisture) actions which makes it effective for treating Santapanajanya Vyadhi (diseases brought on by over nutrition of one or more tissues), such as Prameha (excessive urination), Sthaulya (obesity) etc.

Managing Cardiovascular Risk in Patients with Autoimmune Diseases: Insights from a Nutritional Perspective.

Autoimmune diseases manifest as an immune system response directed against endogenous antigens, exerting a significant influence on a substantial portion of the population. Notably, a leading contributor to morbidity and mortality in this context is cardiovascular disease (CVD). Intriguingly, individuals with autoimmune disorders exhibit a heightened prevalence of CVD compared to the general population. The meticulous management of CV risk factors assumes paramount importance, given the current absence of a standardized solution to this perplexity. This review endeavors to address this challenge from a nutritional perspective. Emerging evidence suggests that inflammation, a common thread in autoimmune diseases, also plays a pivotal role in the pathogenesis of CVD. Nutritional interventions aimed at reducing inflammation have shown promise in mitigating cardiovascular risk. The integration of nutritional strategies into the management plans for patients with autoimmune diseases offers a holistic approach to reducing cardiovascular risk. While conventional pharmacological treatments remain foundational, the addition of targeted dietary interventions can provide a complementary pathway to improve cardiovascular outcomes.

Development and application of a nutritional quality model for life cycle assessment of protein-rich foods

Alternative protein sources (APSs) have emerged as a potentially healthy and, presumably, environmentally sustainable solution for meeting future food demand. Here we develop a new complex nutrient profile model to assess the nutritional quality of protein-rich foods, which, concurrently, allows to evaluate their environmental implications efficiently through the application of life cycle assessment (LCA). The development of the index was guided by the identification of priority nutrients in APSs and main deficiencies of similar models, which gave rise to the ‘quality Nutrient Rich Food 1.10.2’ (qNRF1.10.2). This model is the first nutrient profile system that combines various essential nutrients and a protein quality scoring system, namely Digestible Indispensable Amino Acid Score (DIAAS). From a nutritional perspective, its accuracy was proven and its application identified animal products as the most nutritionally complete food group, surpassing plant-based alternatives. However, when using the index as functional unit in LCA of protein-rich foods, we discovered that seeds, nuts, and mixtures of vegetable foods reported the lowest environmental impacts as a function of their nutrient density. Some exceptions were found for algae or insects, which performed worse than animal-derived foods in terms of resources consumption, or for cereals, which shown an important water deprivation potential. These results suggest that we should find a trade-off between the production of emerging and conventional foodstuffs, and that main environmental issues of each region should condition the location of production systems.

Effects of nutritional interventions on cognitive function in adult cancer survivors: A systematic review.

To evaluate the effectiveness and safety of nutritional interventions (i.e. nutritional support, dietary patterns and dietary supplements) on cognitive function in cancer survivors. Systematic review. A systematic and comprehensive search of PubMed, Web of Science, the Cochrane Library, Embase, and CINAHL was conducted from the inception until March 10, 2023. The last search was conducted on December 10, 2023. PRISMA. A total of 59 randomized controlled trials were included for analysis. Nutritional support, dietary patterns and dietary supplements improved cognitive function in cancer survivors with no apparent safety concerns. The anti-inflammatory diet, the fasting-mimicking diet and the web-based diet significantly improved cognitive function. Whereas the ketogenic diet or dietary advice to consume more soluble dietary fibres and less insoluble dietary fibres and lactose could not. There was evidence from dietary supplements to support the beneficial effects of polyunsaturated fatty acid supplements, traditional herbal medicines and other supplements. Nutritional interventions have great promise for improving cognitive function in adult cancer survivors. Further validation of the nutritional interventions supported in this study in other survivors and exploration of more effective nutritional interventions are needed. This work can support the construction of nutritional support interventions and dietary guidance programs to prevent cancer-related cognitive decline. This work filled a gap in preventive strategies for cancer-related cognitive decline from a nutritional perspective. Nutritional support, dietary patterns, and dietary supplements can prevent cancer-related cognitive decline without serious safety concerns. This work highlighted nutritional interventions that have the potential to improve cognitive function in cancer survivors, benefiting the further construction of evidence-based nutritional intervention programs. PROSPERO. No patient or public contribution.

Algae-Boosted Chickpea Hummus: Improving Nutrition and Texture with Seaweeds and Microalgae.

The global food industry faces a critical challenge in ensuring sustainable practices to meet the demands of a growing population while minimizing environmental impact. At the same time, consumer awareness and the demand for quality products drive innovation and inspire positive changes in the food supply chain. Aiming to create a more sustainable and nutrient-rich alternative, this study is summarized by characterizing the physical and chemical characteristics of algae-enriched chickpea hummus: an innovative approach to popular food products. The algae-enriched hummuses were developed with an incorporation (6% w/w) of Gelidium corneum and Fucus vesiculosus seaweeds and Chlorella vulgaris (hetero and autotrophic) microalgae to reveal their technological potential and evaluate the nutritional and rheological characteristics relative to a control hummus (without algae). From a nutritional perspective, the main results indicated that hummus enriched with microalgae showed an increase in protein content and an improved mineral profile. This was particularly notable for the seaweed F. vesiculosus and the autotrophic microalga C. vulgaris, leading to claims of being a "source of" and "rich in" various minerals. Additionally, the antioxidant activity of hummus containing F. vesiculosus and C. vulgaris increased significantly compared to the control. From a rheological perspective, incorporating algae into the humus strengthened its structure. The microalgae further enhanced the dish's elasticity and firmness, thus improving this chickpea-based dish´s overall texture and quality.

Midwives' and Obstetric Physicians' Practices Related to Pregnancy Nutrition Counseling: A Scoping Review.

Dietary intake during pregnancy impacts short- and long-term maternal and fetal health outcomes. Dietary habits are highly individualized and influenced by contextual factors and social determinants of health within each person's lived environment. Midwives and other health care providers are well positioned to facilitate nutrition conversations and interventions with patients related to recommendations and modifications before and during pregnancy. This scoping review synthesizes the literature on perinatal care providers' attitudes and practices related to antenatal nutrition counseling. An electronic database literature search was conducted in March 2023 using the following inclusion criteria: English language, published between 1990 and 2023, completed in high-income countries, and evaluated provider practices related to educating pregnancy patients on nutrition. Exclusion criteria included comparison or interventional studies as well as those focused on patient perspectives, specialty diets, comorbidities, or pregnancy complications. Thematic analysis was completed to identify common themes and subthemes across studies related to perinatal care providers' perspectives of pregnancy nutrition. Thirty-six articles were included in the final review. Although providers acknowledged the importance of nutrition for pregnancy outcomes, few reported being able to cover the topic in-depth during antenatal visits. Counseling was usually generalized, limited in scope, and lacked consideration of patient-specific contextual factors such as dietary restrictions, preferences, or access to resources needed to follow recommendations. Provider barriers to comprehensive nutrition counseling included lack of training and time during clinic visits and limited availability of guidelines. Multiple gaps in current pregnancy nutrition counseling practices exist. Despite nutrition being viewed by perinatal care providers as an important part of pregnancy, multiple barriers lead to it being overlooked during patient-provider interactions. Contextual factors for both providers and patients contribute to failure of current interventions to consistently and significantly impact dietary habits of pregnant people.

Reintegration of Dairy in Daily American Diets: A Biochemical and Nutritional Perspective

This paper explores the reintegration of dairy products into the daily diets of Americans, with a focus on the biochemical role of lactase, the enzyme responsible for lactose digestion. It examines the benefits of dairy consumption, practical strategies for reintroducing dairy into the diet, and the use of lactase supplements to manage lactose intolerance. This approach aims to enhance nutritional intake and overall health in the lactose- intolerant population.
