Abstract: Purpose of Review Globally, too few children are breastfed as recommended. Commercial promotion of breast-milk substitutes (BMS) is one factor undermining breastfeeding globally. Although the International Code of Marketing of BMS prohibits all forms of marketing, promotion has been observed in digital environments. We aimed to understand the scope and impact of digital marketing for the promotion of BMS. Recent Findings BMS are promoted strategically and in an integrated fashion across multiple digital channels (social media, manufacturer websites, online retailers, blogs, mobile apps and digital streaming services). Traditional marketing strategies like gifts, discounts and coupons are also disseminated digitally. Data mining, real-time direct-to-consumer advertising and partnering with peer-group social media influencers are additional avenues. Exposure to digital marketing is common. Research on the impact of digital marketing is scarce, but its negative impact on breastfeeding intention and initiation has been documented. Case reports from marketing industry press corroborate academic evidence by highlighting the benefits of digital marketing to BMS companies in recruiting new users and increasing sales. Summary To protect and promote breastfeeding, coordinated global action and strengthened national measures will be needed to implement, monitor and enforce the International Code in a digital context. Further action could include voluntary restrictions on BMS marketing by social media platforms and greater use of government-led data and health privacy regulation. PubDate: 2022-05-04

Abstract: Purpose of the Review Food insecurity can have a negative health impact for women during pregnancy and the postpartum period; however, there are a range of barriers to meeting nutritional guidelines during pregnancy. Food insecurity is associated with an increased risk of pregnancy complications and mental and physical health outcomes. This review aims to provide insight into programmes and interventions which have targeted food insecurity in pregnant and early postpartum women. The central research question for this review is as follows: What programmes and interventions have sought to address food insecurity among pregnant and postpartum women' A systematic search of five electronic databases including Medline, CINAHL, Global Health, Embase, and Cochrane was undertaken on August 2021. Key thematic areas searched were food insecurity, pregnancy, nutritional outcomes, and interventions or programmes. Only studies that were published since 2000 in English were considered. Recent Findings Eleven studies were included in this review. Studies employed a range of methods and outcomes measures. They were conducted in mostly low- and middle-income countries, and in general, focused on nutritional supplementation, with some studies also incorporating nutrition education or counselling. Summary The findings of this review suggest that while there are a range of possible interventions that seek to address food insecurity and hunger among pregnant and postpartum women, the limited number of robust evaluations or long-term interventions mean that evidence for any one intervention type is limited. Furthermore, the programmes and interventions that do exist are generally embedded within a single context or structure, and as such, may not be able to be widely implemented.

Abstract: Purpose of Review With the wide recognition of the importance of dietary patterns rather than isolated nutrient groups on health outcomes, numerous diet quality indices have been designed to evaluate the overall food intake quality in the last two decades. Recent Findings The newest version of the Healthy Eating Index (HEI), HEI-2015, is a diet quality index that measures adherence to the recommendations of the 2015–2020 Dietary Guidelines for Americans. While the key nutrient groups are included in most diet quality indices, differences in other components and the scoring system differentiate HEI. The Healthy Beverage Index (HBI) was recently introduced. Previous literature has confirmed the association of the older versions of HEI with metabolic syndrome, inflammatory markers, and negative health outcomes including cardiovascular disease, type 2 diabetes mellitus, chronic kidney disease, and all-cause mortality. Summary This review presents the existing evidence on the association of HEI-2015 and HBI with health markers and long-term outcome, provides guidance on their use, and identifies persisting challenges such as the development of simple, unified, and objective tools to characterize healthy diets in routine clinical practice.

Abstract: Purpose of Review To verify the effects of sodium bicarbonate (NaHCO3) supplementation on biochemical and physical measurements of combat sports athletes. Recent Findings A systematic review of articles indexed in three databases (PubMed, CAPES journal, and Google Scholar) was carried out until October 2020, using descriptors related to NaHCO3 supplementation in combat sports. First, 38 articles were identified. Next, eight articles were selected through the inclusion and exclusion criteria. The methodological quality of the articles was assessed using the Physiotherapy Evidence Database (PEDro) scale (8 and 9 points). Blood lactate, rating of perceived exertion, Special Judo Fitness Test, Dummy throw, and mean and peak powers for Wingate were evaluated. Random effects meta-analysis was used, the effect size was adjusted by corrected Hedges’ g, and the heterogeneity is explored by I2. The results were obtained through weighted average and 95% CI, and the significance limit was set as p < 0.05. Summary NaHCO3 supplementation had a significant effect on increasing blood lactate (p = 0.006) of the athletes studied. However, the performance measures (rating of perceived exertion, power, and specific performance) did not show a significant difference (p ˂ 0.05). In conclusion, NaHCO3 supplementation causes a significant increase in blood lactate, indicating an ergogenic effect on buffer, which can delay the onset of fatigue and contribute to the performance of combat sports athletes. New experimental studies need to be published that assess the effect of acute and chronic NaHCO3 supplementation in specific combat sports tests and in women. PubDate: 2022-04-08

Abstract: Purpose of Review Cow’s milk protein allergy (CMPA) is known as the most common food allergy in the first year of life. For this purpose, in our review, the regulation of maternal and infant nutrition, and the risks and the issues to be considered in terms of nutrition are discussed from the perspective of a dietitian. Recent Findings Therefore, understanding the epidemiology, symptoms, diagnostic criteria, and appropriate treatment of cow’s milk protein allergy is crucial for the multidisciplinary team of physicians, dietitians, and nurses working in the clinic. It has been reported that tolerance develops in approximately 50% of infants affected by cow's milk protein in the first year of life. Although CMPA is generally thought to clear up between 1 and 2 years of age, there is insufficient evidence to determine an optimal time to reintroduce cow's milk protein to the diet. Because the elimination diet recommended in the treatment of children with CMPA, adequate protein and calcium intake of the mother and/or baby in the diet should be evaluated. Studies focusing on metabolic bone turnover in children with food allergies are limited. In general, low calcium intake is associated with reduced bone formation in children with CMPA. Therefore, bone health should be focused on and appropriate strategies should be developed in children with CMPA. Summary Unnecessary elimination of milk and its products, which are an important part of nutrition, should be prevented and nutrient deficiencies and growth status should be monitored by dietitians especially working in the field of pediatric nutrition.

Abstract: Purpose of Review Cardiovascular disease (CVD) is the leading cause of death to on-duty firefighters and is a substantial health concern. Preventative measures, including dietary interventions, may improve CVD in firefighters. The purpose of this review is to examine the literature on the relationship between dietary intake, dietary lifestyle interventions, and risk of CVD in firefighters. Recent Findings Existing evidence, albeit limited, suggests that firefighters do not meet dietary guidelines. Lifestyle modifications featuring dietary interventions are effective in improving risk factors associated with CVD in firefighters. Unfortunately, no consistent nutrition-related trend was identified across the retrieved studies and only a limited number of randomized controlled trials have examined the efficacy of lifestyle intervention studies on CVD in firefighters. Summary Although this review suggests dietary lifestyle interventions may facilitate decreases in risk factors associated with CVD in firefighters, current evidence is limited, and additional research is needed.

Abstract: Purpose of the review To perform a systematic review of prospective clinical trials to determine whether improving vitamin D status improves asthma control. Recent findings In cross sectional studies suboptimal viramin D status is often associated with poor asthma control. However, decreased 25-hydroxycholecalciferol (25 (OH) D) concentrations might not be causally associated with asthma control. Summary We performed a systematic review until December 15, 2021 according to PRISMA guideline, searching MEDLINE, MEDLINE In-Process, Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials. Two searches were performed, the first using “vitamin D” and the second using “Vitamin D” or “ergocalciferol” or “cholecalciferol” and “Asthma”. From 419 retrieved papers, after removal of duplicate and after using exclusion criteria, 28 full-text articles were eligible, of which 6 remained for quantitative analysis and 11 (9 studies) for qualitative analysis. From both analyses, prospective studies do not support that improving the vitamin D status of asthmatic children improves asthma control. PubDate: 2022-03-26

Abstract: Purpose of Review Increasing evidence points toward the importance of diet and its impact on cognitive decline. This review seeks to clarify the impact of four diets on cognition: the Mediterranean diet, the anti-inflammatory diet, the Seventh Day Adventist diet, and the Ketogenic diet. Recent Findings Of the diets reviewed, the Mediterranean diet provides the strongest evidence for efficacy. Studies regarding the anti-inflammatory diet and Seventh Day Adventist diet are sparse, heterogeneous in quality and outcome measurements, providing limited reliable data. There is also minimal research confirming the cognitive benefits of the Ketogenic diet. Summary Increasing evidence supports the use of the Mediterranean diet to reduce cognitive decline. The MIND-diet, a combination of the Mediterranean and DASH diets, seems especially promising, likely due to its anti-inflammatory properties. The Ketogenic diet may also have potential efficacy; however, adherence in older populations may be difficult given frequent adverse effects. Future research should focus on long-term, well-controlled studies confirming the impact of various diets, as well as the combination of diets and lifestyle modification. PubDate: 2022-03-26

Abstract: Purpose of Review This review evaluated recent randomized controlled trials (RCTs) examining the chronic intake of whole foods associated with the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurogenerative Delay (MIND), and ketogenic (KETO) diets on cognitive function. Recent Findings We identified RCTs related to olive oil (N = 3), nuts (N = 7), fatty fish (N = 1), lean meats (N = 4), fruits and vegetables (N = 9), legumes (N = 1), and low-fat dairy (N = 4), with 26/29 reporting positive results on at least one measure of cognition. We also identified 6 RCTs related to whole food–induced KETO diets, with half reporting positive effects on cognition. Summary Variations in study design (i.e., generally the studies are < 6 months and include middle-aged and older, cognitively intact participants) and small sample sizes make it difficult to draw conclusions across studies; however, the current evidence from RCTs generally supports individual component intakes of these dietary patterns as an effective, nonpharmacological approach to improve cognitive health in adults.

Abstract: Purpose of the Review The aim is to examine data from clinical trials and prospective longitudinal studies that evaluate the effect of infant formula supplements on the cognitive function of children. Recent Findings A total of 300 articles from 2000 to 2021 were selected. The most researched IF supplements were initially long-chain polyunsaturated fatty acids (LC-PUFA), some proteins and, recently, milk fat globule membrane (MFGM). Supplementation of IF with LC-PUFA led to some positive effects on specific cognitive functions or no effect; however, there was no consistent benefit for cognitive function. Modifying the amount of proteins did not affect the children’s neuropsychological tests. Supplementation of IF with MFGM and its components had beneficial effects on child cognitive development in the short term, but no effect was observed in the long term. Summary Further studies are needed to confirm the safety of supplementation on the development of cognitive function in children fed with infant formula. PubDate: 2022-03-25

Abstract: Purpose of Review The purpose of this review is to summarize the recent (past 5 years) available evidence regarding the association between plant-based diets on cancer risk from clinical trials and observational studies. Biological mechanisms and gaps in the current literature will also be discussed. Recent Findings There is a lack of intervention studies but there are abundant observational studies assessing the association between plant-based diets and cancer risk, including multiple longitudinal cohort studies and similar data from case–control studies that demonstrate a decreased overall cancer risk with plant-based diets. Case–control studies support a decreased risk of colorectal and breast cancers with plant-based diets, but results for specific cancers remain inconsistent in cohort studies. Summary Current evidence from observational studies indicates an inverse association between plant-based diets and overall cancer risk. Future research should include intervention studies, address inconsistencies in dietary assessment methods and provide greater detail on underrepresented groups. PubDate: 2022-03-25

Abstract: Purpose of Review Nutrition often focuses on food composition, yet differences in food form, texture, and matrix influence energy intake and metabolism. This review outlines how these attributes of food impact oral processing, energy intake, and metabolism. Recent Findings Food form has a well-established impact on intake, where liquids are consumed more than solids and semi-solids. For solids, texture properties like thickness, hardness, and lubrication, and geometrical properties like size and shape influence oral processing, eating rate, and intake. Food matrix integrity can influence nutrient and energy absorption and is strongly influenced by food processing. Summary Food texture and matrix play important roles in modulating energy intake and absorption. Future research needs to consider the often overlooked role of texture and matrix effects on energy and metabolic responses to composite foods and meals. Research is needed to understand how processing impacts macro- and micro-structure of food and its long-term impact on energy balance and health. PubDate: 2022-03-24

Abstract: Purpose of Review Drug-resistant epilepsy represents around one-quarter of epilepsies worldwide. Although ketogenic diets (KD) have been used for refractory epilepsy since 1921, the past 15 years have witnessed an explosion of KD use in the management of epilepsy. We aimed to review evidence from randomized controlled trials (RCTs) regarding the efficacy and safety of KD in drug-resistant epilepsy in children and adolescents. Recent Findings A literature search was performed in the Pubmed, Cohrane, Scopus, ClinicalTrials.gov, and Google Scholar databases. Predefined criteria were implemented regarding data extraction and study quality. Data were extracted from 14 RCTs in 1114 children and adolescents aged from 6 months to 18 years. Primary outcome was seizure reduction after the intervention. In 6 out of the 14 studies, there was a statistical significant seizure reduction by > 50% in the KD-treated group compared with the control group over a follow-up of 3–4 months. Secondary outcomes were adverse events, seizure severity, quality of life, and behavior. Gastrointestinal symptoms were the most frequent adverse events. Serious adverse events were rare. Summary We conclude that the KD is an effective treatment for drug-resistant epilepsy in children and adolescents. Accordingly, RCTs investigating long-term impact, cognitive and behavioral effects, and cost-effectiveness are much anticipated. PubDate: 2022-03-18

Abstract: Purpose of Review A key driver of unhealthy diets in children is the marketing of unhealthy foods and beverages. Attempts to regulate children’s exposure to unhealthy food marketing through government-led policies are challenged by commercial interests. Parents shoulder the responsibility of counteracting the effects of omnipresent unhealthy food marketing that children are exposed to within the food environment. In this narrative review we aimed to synthesise the evidence over the last 10 years on parents' perceptions of children’s exposure to unhealthy food marketing and parents support for policies to restrict this marketing. Recent Findings The evidence indicates that unhealthy food marketing leads parents to feel undermined in their ability to provide healthy foods to their children. Despite this concern, parents tend to underestimate the levels of exposure to, and impacts of, unhealthy food marketing to their children, especially in the digital ecosystem. Summary The voices and support of parents represent a significant opportunity to accelerate policy action on food marketing. Increasing awareness among parents and caregivers to the high levels and harmful impacts of children’s exposure to unhealthy food marketing, focusing on their right not to be undermined by such action, may drive support for policy change. Further research is needed to understand parents’ attitudes and perceptions related to their children’s exposure to contemporary unhealthy food marketing, specifically in digital environments, and the perspectives of fathers and parents from low and middle-income countries.

Abstract: Purpose of Review Sports nutrition guidelines typically state that athletes desiring weight gain follow a regimen that includes increasing energy intake by ~ 300–500 kcal/day with an emphasis on adequate protein and carbohydrate and judicious inclusion of energy-dense foods, in combination with rigorous resistance training. This regimen is thought to promote weekly gains of ~ 0.45 kg (1 lb), mostly as lean body mass (LBM). This review summarizes the evidence supporting these intentional weight gain regimens in athletes. Recent Findings Although some research has been conducted in the past 5 years, research on intentional weight gain is lacking. Summary Currently, available data suggests that weekly weight gain of 0.45 kg (1 lb), primarily as LBM, may be difficult for some athletes to achieve. Available evidence, however, suggests that commonly recommended strategies to promote calorie surplus, including consuming larger portions, incorporating energy-dense foods, and prioritizing liquid over solid foods, may prove helpful.

Abstract: Purpose of review Food systems at all levels are experiencing various states of dysfunction and crisis, and in turn their governance contributes to other intensifying crises, such as climate change, biodiversity loss and the rapid expansion of dietary-related non-communicable diseases. In many jurisdictions governments at local, state and national levels are taking action to tackle some of the key challenges confronting food systems through a range of regulatory, legislative and fiscal measures. This article comprises a narrative review summarising recent relevant literature with a focus on the intersection between corporate power and public health. The review sought to identify some of the principal barriers for the design and support of healthy food systems and environments, as well as key reforms that can be adopted to address these barriers, with a focus on the role of local governments. Recent findings The review found that, where permitted to do so by authorising legislative and regulatory frameworks, and where political and executive leadership prioritises healthy and sustainable food systems, local governments have demonstrated the capacity to exercise legislative and regulatory powers, such as planning powers to constrain the expansion of the fast food industry. In doing so, they have been able to advance broader goals of public health and wellbeing, as well as support the strengthening and expansion of healthy and sustainable food systems. Summary Whilst local governments in various jurisdictions have demonstrated the capacity to take effective action to advance public health and environmental goals, such interventions take place in the context of a food system dominated by the corporate determinants of health. Accordingly, their wider health-promoting impact will remain limited in the absence of substantive reform at all levels of government. PubDate: 2022-02-12 DOI: 10.1007/s13668-022-00393-5

Abstract: Purpose of Review Reduction of child malnutrition in conflict settings is on top of the international agenda on sustainable development. This association between child malnutrition and conflict has been hypothesised in the academic literature but not rigorously examined empirically till recently. This paper reviews the emerging quantitative literature, including conflict as an explanatory variable to understand the aspects of child malnutrition studied and how violent events are associated with child nutritional status. Limitations are also highlighted. Recent Findings Child malnutrition is investigated into its three main dimensions of stunting, wasting and undernourishment computed as z-score. Conflict is mostly studied in terms of duration, number of events, typology and intensity. Summary The emerging literature generally establishes a significant and negative association between conflict and child malnutrition. However, limitations persist and are mainly due to the type of available data. PubDate: 2022-01-30 DOI: 10.1007/s13668-021-00386-w

Abstract: Purpose of Review Chronic kidney disease (CKD) is epidemic throughout the word. Despite various novel therapeutic opportunities, CKD is still associated with high morbidity and mortality. In CKD, patient’s chronic inflammation is frequent and related with adverse outcomes. Both innate and adaptive immunity are dysfunctional in CKD. Therefore, it is plausible to interfere with dysfunctional immunity in these patients. In the current review, we present the updated experimental and clinical data summarizing the effects of nutritional interventions including natural products and dietary supplements on immune dysfunction in the context of CKD. Recent Findings Nutritional interventions including natural products and dietary supplements (e.g., curcumin, sulforaphane, resistant starch, anthocyanin, chrysin, short chain fatty acids, fish oil resistant starch) slow down the inflammation by at least 6 mechanisms: (i) decrease nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB); (ii) decrease NLR family pyrin domain containing 3 (NLRP3); (iii) decrease interleukin-1 (IL-1), decrease interleukin-6 (IL-6) secretion; (iv) decrease polymorphonuclear priming); (v) promote anti-inflammatory pathways (nuclear factor-erythroid factor 2-related factor 2 (NFR2); (vi) increase T regulatory (Tregs) cells). Summary Natural products and dietary supplements may provide benefit in terms of kidney health. By modulation of nutritional intake, progression of CKD may be delayed.

Abstract: Purpose of Review The aim of the review was to evaluate which diets are associated with higher TMAO levels. Recent Findings Several studies have shown that plasma and urinary levels of trimethylamine N-oxide (TMAO) are a reliable indicator of cardiovascular disease risk. Diet certainly has a strong influence on TMAO levels, but there is still uncertainty about which diet is the most effective in reducing this risk factor. Summary PubMed, Web of Science and Scopus were searched for studies that were published up until July 1, 2021 using specific keywords. In total, 447 studies were evaluated, of which papers on individual foods or supplements, or conducted in children, in vitro or in animal model studies were excluded. Twenty-five studies were included in this review. Three studies showed that caloric restriction and (visceral) weight loss improve TMAO levels. Six out of eight studies revealed beneficial effects of plant-based diets on plasma or urinary TMAO concentrations. Most of the studies demonstrated that a diet high in protein, particularly of animal origin, such as diets rich in fish or red meat, have negative effects on TMAO levels. Most studies that have evaluated the relationship between diet and plasma or urinary concentrations of TMAO seem to indicate that plant-based diets (Mediterranean, vegetarian and vegan) are effective in improving TMAO levels, while animal-based diets appear to have the opposite effect. Further long-term studies are needed to assess whether vegetarian or vegan diets are more effective than the Mediterranean diet in reducing TMAO levels.
