Obesity is related to the increased risk for chronic diseases and to nutrient insufficiencies, a paradox that has been characterised as the “double burden of malnutrition”. The aim of this study was to examine the effectiveness of a computerised decision-support tool as a means of childhood obesity management. The effectiveness of the decision-support tool was assessed through a pilot randomised controlled intervention trial. The study recruited a total sample of 80 children (obese or overweight) with an age range between 6 and 12 years. The participants were allocated to two study groups – intervention group and control group. Results indicate that a computerised decision-support tool, designed to assist paediatric healthcare professionals in providing personalised nutrition and lifestyle optimisation recommendations to overweight or obese children and their parents, can result in favourable changes to certain dietary intake and anthropometric indices in the children that received the intervention. Authors conclude that the computerised decision-support tool resulted in improvement of the children’s dietary intake and body mass index. Hence, the tool can support clinicians to improve the effectiveness of care.
Abstract
We examined the effectiveness of a computerised decision-support tool (DST), designed for paediatric healthcare professionals, as a means to tackle childhood obesity. A randomised controlled trial was conducted with 65 families of 6⁻12-year old overweight or obese children. Paediatricians, paediatric endocrinologists and a dietitian in two children's hospitals implemented the intervention. The intervention group (IG) received personalised meal plans and lifestyle optimisation recommendations via the DST, while families in the control group (CG) received general recommendations. After three months of intervention, the IG had a significant change in dietary fibre and sucrose intake by 4.1 and -4.6 g/day, respectively. In addition, the IG significantly reduced consumption of sweets (i.e., chocolates and cakes) and salty snacks (i.e., potato chips) by -0.1 and -0.3 portions/day, respectively. Furthermore, the CG had a significant increase of body weight and waist circumference by 1.4 kg and 2.1 cm, respectively, while Body Mass Index (BMI) decreased only in the IG by -0.4 kg/m². However, the aforementioned findings did not differ significantly between study groups. In conclusion, these findings indicate the dynamics of the DST in supporting paediatric healthcare professionals to improve the effectiveness of care in modifying obesity-related behaviours. Further research is needed to confirm these findings.

While fermented foods have long been produced, a renewed interest has been observed in Western countries. Several reviews have investigated the health benefits of fermented foods, however none of them have discussed the components that form upon fermentation and their possible effect on health. The purpose of this study was to provide a comprehensive review of the health-promoting components of fermentation in order to better understand their role in healthy diets. This systematic review found fermentation increased antioxidant activity of milks, cereals, fruit, vegetables, meat and fish based on 125 analysed articles. Fermentation of different food categories led to varying health benefits including vitamin content, probiotic activity and anti-hypertensive properties. Based on the existing literature, the authors conclude fermented foods should be consumed regularly and recommend they be included in worldwide dietary guidelines.
Abstract
Fermented foods have long been produced according to knowledge passed down from generation to generation and with no understanding of the potential role of the microorganism(s) involved in the process. However, the scientific and technological revolution in Western countries made fermentation turn from a household to a controlled process suitable for industrial scale production systems intended for the mass marketplace. The aim of this paper is to provide an up-to-date review of the latest studies which investigated the health-promoting components forming upon fermentation of the main food matrices, in order to contribute to understanding their important role in healthy diets and relevance in national dietary recommendations worldwide. Formation of antioxidant, bioactive, anti-hypertensive, anti-diabetic, and FODMAP-reducing components in fermented foods are mainly presented and discussed. Fermentation was found to increase antioxidant activity of milks, cereals, fruit and vegetables, meat and fish. Anti-hypertensive peptides are detected in fermented milk and cereals. Changes in vitamin content are mainly observed in fermented milk and fruits. Fermented milk and fruit juice were found to have probiotic activity. Other effects such as anti-diabetic properties, FODMAP reduction, and changes in fatty acid profile are peculiar of specific food categories.

Plain language summary
Anthocyanins (ACNs) are plant compounds belonging to the flavonoid group of polyphenols and are naturally occurring in a number of foods. They are responsible for the red, blue and purple pigmentation within plant foods, such as blueberries and raspberries and are known to contain therapeutic compounds. Several studies have investigated the anti-inflammatory, antioxidant and blood pressure modulation properties within ACNs, however, results for blood pressure modulation, unlike those for anti-inflammatory and antioxidant properties have been mixed and less consistent. This paper reviews 66 human intervention trials exploring the effects of various forms of ACNs, like whole berries, concentrates and freeze-dried powders in order to identify the singular variables related to blood pressure modulation in order to further investigate. Having looked at a number of variables within the trials, researchers concluded that ACNs do in fact contain blood pressure lowering properties, but further research into varying factors including dose effect, synergistic effects, absorption and metabolism and the functionality of the individuals gut microbiota is needed to clarify results further.
Abstract
Dietary intake of anthocyanins (ACNs) is associated with a reduced risk of cardiovascular and coronary heart disease. While the anti-inflammatory, antioxidant, and lipid-lowering effects of ACN consumption have been consistently reported, their effect(s) on blood pressure regulation is less consistent and results from human studies are mixed. The objective of this review is attempting to identify potential patterns which may explain the variability in results related to blood pressure. To do so, we review 66 human intervention trials testing the effects on blood pressure of purified ACN or ACN-rich extracts, or whole berries, berry juices, powders, purees and whole phenolic extracts, from berries that are rich in ACN and have ACNs as predominant bioactives. Several factors appear to be involved on the mixed results reported. In particular, the baseline characteristics of the population in terms of blood pressure and total flavonoid intake, the dose and duration of the intervention, the differential effects of individual ACN and their synergistic effects with other phytochemicals, the ACN content and bioavailability from the food matrix, and individual differences in ACN absorption and metabolism related to genotype and microbiota enterotypes.

Plain language summary
Hypertension is the major leading risk factor for atherosclerosis and several diseases, especially renal and cardiovascular disorders, including myocardial infarction, stroke, and heart failure. The aim of this study was to summarize meta-analyses studying the effect and associations of electrolytes as supplements or diets on human blood pressure or risk for hypertension throughout the last years. The study is a review that summarizes meta-analyses of publications studying the effect or association between electrolytes and blood pressure. Meta-analyses of randomized controlled trials or observational studies were included in this review. The major findings of this review indicate that: 1. Sodium (salt) reduction and a higher intake of potassium have convincing blood pressure lowering effects, 2. Higher magnesium intake is suggested to possibly reduce blood pressure, especially in patients with hypertension, and 3. Sufficient calcium intake confers a protective effect regarding the risk for gestational hypertension. Authors conclude that lowering sodium and increasing potassium intake would exert convincing blood pressure lowering effects, especially in hypertensive patients.
Abstract
Nutrition is known to exert an undeniable impact on blood pressure with especially salt (sodium chloride), but also potassium, playing a prominent role. The aim of this review was to summarize meta-analyses studying the effect of different electrolytes on blood pressure or risk for hypertension, respectively. Overall, 32 meta-analyses evaluating the effect of sodium, potassium, calcium and magnesium on human blood pressure or hypertension risk were included after literature search. Most of the meta-analyses showed beneficial blood pressure lowering effects with the extent of systolic blood pressure reduction ranging between -0.7 (95% confidence interval: -2.6 to 1.2) to -8.9 (-14.1 to -3.7) mmHg for sodium/salt reduction, -3.5 (-5.2 to -1.8) to -9.5 (-10.8 to -8.1) mmHg for potassium, and -0.2 (-0.4 to -0.03) to -18.7 (-22.5 to -15.0) mmHg for magnesium. The range for diastolic blood pressure reduction was 0.03 (-0.4 to 0.4) to -5.9 (-9.7 to -2.1) mmHg for sodium/salt reduction, -2 (-3.1 to -0.9) to -6.4 (-7.3 to -5.6) mmHg for potassium, and -0.3 (-0.5 to -0.03) to -10.9 (-13.1 to -8.7) mmHg for magnesium. Moreover, sufficient calcium intake was found to reduce the risk of gestational hypertension.

Plain language summary
The prevalence of diabetes has been increasing worldwide. The accompanying increase in the prevalence of diabetes-related complications and the occurrence of diabetes are likely to have a substantial impact on healthcare costs. The aim of the study was to compare the effectiveness of lifestyle modifications to other treatments for patients at high risk of type 2 diabetes. The study design is a systemic review of published literature and a network meta-analysis of data from each selected study. Forty-seven interventions were used for the analyses. The results of the meta-analysis highlight the efficacy of lifestyle modification in preventing the onset of type 2 diabetes in high-risk patients in comparison with standard treatment or placebo as well as other treatments. The proportion of patients with onset of type 2 diabetes in the intervention (lifestyle modification) group was approximately twice as low as compared to the control (standard intervention) group. Authors conclude that lifestyle modification is the superior treatment intervention among 12 treatments for the prevention of type 2 diabetes in high-risk individuals.
Abstract
BACKGROUND Many clinical trials have been conducted to verify the effects of interventions for prevention of type 2 diabetes (T2D) using different treatments and outcomes. The aim of this study was to compare the effectiveness of lifestyle modifications (LM) with other treatments in persons at high risk of T2D by a network meta-analysis (NMA). METHODS Searches were performed of PUBMED up to January 2018 to identify randomized controlled trials. The odds ratio (OR) with onset of T2D at 1 year in the intervention group (LM, dietary, exercise, or medication) versus a control group (standard treatments or placebo) were the effect sizes. Frequentist and Bayesian NMAs were conducted. RESULTS Forty-seven interventions and 12 treatments (20,113 participants) were used for the analyses. The OR in the LM was approximately 0.46 (95% CI: 0.33 to 0.61) times lower compared to the standard intervention by the Bayesian approach. The effects of LM compared to other treatments by indirect comparisons were not significant. CONCLUSIONS This meta-analysis further strengthened the evidence that LM reduces the onset of T2D compared to standard and placebo interventions and appears to be at least as effective as nine other treatments in preventing T2D.

Plain language summary
High blood pressure (BP) accounts for approximately 50% of cardiovascular disease morbidity worldwide. The aim of this study was to examine the effect of a vegetarian diet on BP in participants with or without proteinuria [the earliest marker of kidney damage]. This study is a large retrospective cross-sectional study. The medical records of 36,617 individuals, 16,415 (44.8%) males and 20,202 (55.2%) females were examined. Results indicate that a vegan diet was significantly associated with lower systolic and diastolic BP compared with a nonvegetarian diet in asymptomatic participants with proteinuria. Authors conclude that a vegan diet could be an effective nonpharmacologic approach to reduce BP.
Abstract
OBJECTIVE Previous studies have reported that a vegetarian diet may lower blood pressure (BP), but the effect of diet on BP in asymptomatic participants with proteinuria is unknown. We examined the association of diet and BP in individuals with or without proteinuria. MATERIALS AND METHODS This cross-sectional study analyzed data from participants who were more than 40 years old and received physical checkups at Taipei Tzu Chi Hospital from September 5, 2005, to December 31, 2016. Diets were assessed at baseline by a self-reported questionnaire and categorized as vegan, lacto-ovo vegetarian, or omnivore. There were 2818 (7.7%) vegans, 5616 (15.3%) lacto-ovo vegetarians, and 28,183 (77.0%) omnivores. The effect of different parameters on BP was determined using a multivariate multiple linear regression model with no intercept, with control for important characteristics and lifestyle confounders. RESULTS The vegan group had a lower mean systolic BP (-3.87 mmHg, P < 0.001) and diastolic BP (-2.48 mmHg, P < 0.001) than the omnivore group. Participants with proteinuria had a higher systolic BP (4.26 mmHg, P < 0.001) and diastolic BP (2.15 mmHg, P < 0.001) than those without proteinuria. Interaction analysis indicated that vegan participants with proteinuria had a lower systolic BP (-2.73 mmHg, P = 0.046) and diastolic BP (-2.54 mmHg, P = 0.013) than other participants with proteinuria. However, individuals in the lacto-ovo group with proteinuria had a BP similar to other participants with proteinuria. CONCLUSIONS A vegan diet was associated with lower BP in asymptomatic participants with proteinuria. This diet could be a nonpharmacologic method to reduce BP.

Coeliac disease (CD) is the best-recognised gluten-related disorder (GRD), and it is characterized by a small bowel enteropathy occurring in genetically susceptible individuals whilst exposed to the protein gliadin. The aim of this study was to systematically review the current literature in order to establish the relationship between headache and CD. This study is a systematic review of 40 articles, studying a total of 42,388 individuals with either headache or GRD. Results show that: - There is an increased prevalence of headache amongst patients with CD. - There is an increased prevalence of CD amongst patients with idiopathic headache. - Headaches associated with CD are mainly migraines. - Gluten-free diet is a very effective treatment for headaches associated with CD. Authors conclude that further studies on the prevalence of gluten sensitivity in patients with idiopathic headache are needed, including further research on the pathogenetic mechanisms.
Abstract
OBJECTIVE The aim of this systematic review was to explore the relationship between coeliac disease (CD) and headache. The objectives were to establish the prevalence of each entity amongst the other, to explore the role of gluten free diet (GFD), and to describe the imaging findings in those affected by headaches associated with CD. METHODOLOGY A systematic computer-based literature search was conducted on the PubMed database. Information regarding study type, population size, the age group included, prevalence of CD amongst those with headache and vice versa, imaging results, the nature of headache, and response to GFD. RESULTS In total, 40 articles published between 1987 and 2017 qualified for inclusion in this review. The mean pooled prevalence of headache amongst those with CD was 26% (95% CI 19.5⁻33.9%) in adult populations and 18.3% (95% CI 10.4⁻30.2%) in paediatric populations. The headaches are most often migraine-like. In children with idiopathic headache, the prevalence of CD is 2.4% (95% CI 1.5⁻3.7%), whereas data for adult populations is presently unavailable. Brain imaging can be normal, although, cerebral calcifications on CT, white matter abnormalities on MRI and deranged regional cerebral blood flow on SPECT can be present. GFD appears to be an effective management for headache in the context of CD, leading to total resolution of headaches in up to 75% of patients. CONCLUSIONS There is an increased prevalence of CD amongst idiopathic headache and vice versa. Therefore, patients with headache of unknown origin should be screened for CD, as such patients may symptomatically benefit from a GFD.

Coronary heart disease (CHD) remains the leading cause of mortality in developed countries and is rapidly becoming a dominant cause of all deaths worldwide. The most important modifiable risk factor for cardiovascular disease is diet. A diet which includes non-hydrogenated unsaturated fats as the predominant form of dietary fat, whole grains as the main form of carbohydrates, an abundance of fruits and vegetables and adequate omega-3 fatty acids, can offer significant protection against CHD. The primary aim of the study was to estimate a diet's antioxidant capacity and assess the hierarchy of contribution of particular food products to a Dietary Antioxidant Index (DAI). The study included 143 men and women aged 65-80 who were independent and without any physical or mental disability. On average, the DAI of study participants was low, with fruit having the largest contribution. In comparison to results obtained in a previous report by the same authors, the study showed that the participants consumed too little antioxidant food, as well as grains and cereal-based products, fresh herbs and beverages. This study recommends that the elderly population should be advised to consume a well-balanced diet rich in antioxidants originating from fresh fruit, vegetables and wholegrains to reduce the risk of CHD.
Abstract
INTRODUCTION Some literature data indicate that the proper intake of exogenic antioxidants from food and the proper intake of fats can offer significant protection against coronary heart disease. OBJECTIVES The estimation of total antioxidant capacity of food intake on the basis of Dietary Antioxidant Index (DAI), together with an assessment of the contribution of particular food products in DAI, and the evaluation of consumption of all dietary fats and frequency of consumption of products that are a source of fats among elderly people in Krakow, Poland. MATERIAL AND METHODS 143 persons (73 women and 70 men) aged 65-80 were studied. None of them was under specialist medical control, including cardiological control. DAI was investigated on the basis of the Food Frequency Questionnaire (FFQ) which included 145 food items. DAI was measured using the method by Benzi and expressed as FRAP (the ability to reduce Fe3+ to Fe2+, measured in mMol/l). The daily intake of fats was estimated using the 24-h nutritional recall. The frequency of fats consumption was estimated with the usage of FFQ. For statistical analysis, χ2 test was used. RESULTS The mean value of DAI of all studied persons was 34.27 + 11.72 mMol/l. The largest percentage of those studied had FRAP values in the range 25-35 mMol/l. The highest contribution in the total DAI value was found in fruit (36.2%), grains and cereal-based products (23.6%), and beverages (24.0%). The consumption of vegetables was on the fourth position (7.1%). The contribution of the remaining food products was low. The consumption of total fats (about 70g/24h) and saturated fatty acids (14% of energetic value) exceeded the recommendations. The participation of mono-and polyunsaturated fatty acids in the diets was not in accordance with recommendations. The most frequently consumed fats were animal fats (sausages, butter) and cakes, but the consumption of vegetable oils, fish, nuts and seeds of oil plants was too low. CONCLUSIONS The majority of elderly people made mistakes in their nutrition. The enrichment in natural antioxidants of the diets of elderly people and the normalization of their fats consumption should become an important element of primary and secondary prophylaxis of cardiovascular diseases.

Plain language summary
Palm oil, the most widely consumed vegetable oil in the world, derives from the palm tree fruit with a balanced ratio of unsaturated and saturated fatty acids. Studies have shown an association between high contents of saturated fats in palm oil with the detrimental atherogenic profile. The review aims at synthesising the available evidence reporting the association of palm oil consumption with cardiovascular disease risk and cardiovascular disease-specific mortality, including specifically Coronary Heart Disease (CHD) and stroke. The authors systematically searched three databases up to June 2017 without restriction on setting or language. Published interventional and observational studies that evaluated palm oil consumption with coronary heart disease or stroke in adults were searched. Separate searches were performed depending on the outcome. The study did not find a clear association between palm oil consumption and risk or mortality of cardiovascular disease, namely coronary heart disease and stroke. The health effects found between association of palm oil consumption and risk of coronary heart disease were not unique to just palm oil consumption as other food items were also included in the analysis. The review could not establish strong evidence for or against palm oil consumption relating to cardiovascular disease risk and cardiovascular disease-specific mortality. A healthy overall diet is suggested for good cardiometabolic health.
Abstract
BACKGROUND The high amount of saturated fatty acids (SFA) coupled with the rising availability and consumption of palm oil have lead to the assumption that palm oil contributes to the increased prevalence of cardiovascular diseases worldwide. We aimed at systematically synthesising the association of palm oil consumption with cardiovascular disease risk and cardiovascular disease-specific mortality. METHODS We systematically searched Central, Medline and Embase databases up to June 2017 without restriction on setting or language. We performed separate searches based on the outcomes: coronary heart disease and stroke, using keywords related to these outcomes and palm oil. We searched for published interventional and observational studies in adults (Age: >18 years old). Two investigators extracted data and a consensus was reached with involvement of a third. Only narrative synthesis was performed for all of the studies, as the data could not be pooled. RESULTS Our search retrieved 2,738 citations for stroke with one included study and 1,777 citations for coronary heart disease (CHD) with four included studies. Palmitic acid was reported to be associated with risk of myocardial infarction (MI) (OR 2.76; 95%CI = 1.39-5.47). Total SFA intake was reported to be not significant for risk of MI. Varying intake of fried foods, highest contributor to total SFA with 36% of households using palm oil for frying, showed no significant associations to risk of MI. Odds of developing first non-fatal acute MI was higher in palm oil compared to soybean oil with 5% trans-fat (OR = 1.33; 95%CI = 1.09-1.62) than palm oil compared to soybean oil with 22% trans-fat (OR = 1.16; 95%CI = 0.86-1.56). Nevertheless, these risk estimates were non-significant and imprecise. The trend amongst those taking staple pattern diet (characterised by higher palm oil, red meat and added sugar consumption) was inconsistent across the factor score quintiles. During the years of 1980 and 1997, for every additional kilogram of palm oil consumed per-capita annually, CHD mortality risk was 68 deaths per 100,000 (95% CI = 21-115) in developing countries and 17 deaths per 100,000 (95%CI = 5.3-29) in high-income countries, whereas stroke was associated with 19 deaths per 100,000 (95%CI = -12-49) and 5.1 deaths per 100,000 (95% CI: -1.2-11) respectively. The evidence for the outcomes of this review were all graded as very low. The findings of this review should be interpreted with some caution, owing to the lack of a pooled effect estimate of the association, significant bias in selection criteria and confounding factors, inclusion of other food items together with palm oil, and the possible out-dated trend in the ecological study. CONCLUSION In view of the abundance of palm oil in the market, quantifying its true association with CVD outcomes is challenging. The present review could not establish strong evidence for or against palm oil consumption relating to cardiovascular disease risk and cardiovascular disease-specific mortality. Further studies are needed to establish the association of palm oil with CVD. A healthy overall diet should still be prioritised for good cardiometabolic health.

Plain language summary
Obesity is medically defined as a condition of abnormal or excessive fat accumulation in adipose tissue, of sufficient extent to produce adverse health consequences. Presently, adipose tissue has emerged as an extremely active endocrine organ, based on its ability to secrete a plethora of biologically active adipokines [a class of cytokine mediators that are predominantly secreted by adipose cells] such as leptin and adiponectin. Furthermore, obesity is characterized by an increase in circulating leptin concentrations, in parallel to a decrease in blood levels of adiponectin. Thus, the adiponectin/leptin ratio has been suggested as a marker of adipose tissue dysfunction. A dysfunctional adipose tissue, evidenced by a lower adiponectin/ leptin ratio, is a clear contributor to the low-grade chronic inflammation associated with metabolic syndrome. Authors conclude that this ratio is highly and negatively correlated with markers of low-grade chronic inflammation emerging as a useful estimator of obesity- and metabolic syndrome- associated cardiometabolic risk.
Abstract
Obesity is currently the most extended metabolic disturbance worldwide favoring the development of cardiometabolic alterations such as type 2 diabetes, hypertension, and dyslipidemia. Obesity and the metabolic syndrome (MS) are characterized by an increase in circulating leptin concentrations, in parallel to a decrease in blood levels of adiponectin. Consequently, the adiponectin/leptin ratio has been suggested as a maker of adipose tissue dysfunction. This emerging biomarker correlates with insulin resistance better than adiponectin or leptin alone, or even HOMA and is decreased with increasing number of metabolic risk factors having been proposed as a predictive marker for the MS. Moreover, the adiponectin/leptin ratio is negatively correlated with markers of low-grade chronic inflammation. In this sense, an increase in this ratio has been related with reduced atherosclerosis risk as well as with a decreased risk of some types of cancer in epidemiological studies. In this commentary we propose new cutoffs to estimate obesity- and MS-associated cardiometabolic risk according to the adiponectin/leptin ratio and discuss different therapeutic strategies to increase this promising biomarker of metabolic risk.
