Plain language summary
Diet, mental health, and well-being are linked through several biological pathways. In addition to a healthy diet, nutrient supplements may be of benefit due to their ability to influence these pathways. This review aimed to outline the relationship between specific nutrients and their beneficial effect on mental health. The review outlined the various benefits of polyunsaturated fats, vitamin E, magnesium and folic acid on stress, anxiety, sleep disorders, mild cognitive impairment, depression, bipolar disorders, and obsessive-compulsive disorder. With regards to stress, it was outlined that insufficient vitamins, excessive fat and nutritional imbalance can be contributory. Human research exists to support the benefits of magnesium and polyunsaturated fat for stress and these plus vitamin E for anxiety, however it appears that evidence is lacking for vitamin E and stress and the authors did not comment on folic acid for either condition. Extensive research exists for the use of polyunsaturated fats in mild cognitive impairment, and it was stated that high doses for long periods of time may be needed to show any benefits. The use of vitamin E in cognitive impairment is controversial and more studies may be needed. The authors did not comment on magnesium or folic acid supplementation. It was concluded that an unhealthy diet and lifestyle may be associated with poor mental health and well-being and the importance of a balanced, varied diet for normal brain function. This study could be used by healthcare professionals to understand the importance of recommending a healthy diet for mental well-being in individuals who are suffering from mental health disorders.
Abstract
A good nutritional status is important for maintaining normal body function and preventing or mitigating the dysfunction induced by internal or external factors. Nutritional deficiencies often result in impaired function, and, conversely, intakes at recommended levels can resume or further enhance body functions. An increasing number of studies are revealing that diet and nutrition are critical not only for physiology and body composition, but also have significant effects on mood and mental well-being. In particular, Western dietary habits have been the object of several research studies focusing on the relationship between nutrition and mental health. This review aims to summarize the current knowledge about the relationship between the intake of specific micro- and macronutrients, including eicosapentaenoic acid, docosahexaenoic acid, alpha-tocopherol, magnesium and folic acid, and mental health, with particular reference to their beneficial effect on stress, sleep disorders, anxiety, mild cognitive impairment, as well as on neuropsychiatric disorders, all significantly affecting the quality of life of an increasing number of people. Overall data support a positive role for the nutrients mentioned above in the preservation of normal brain function and mental well-being, also through the control of neuroinflammation, and encourage their integration in a well-balanced and varied diet, accompanied by a healthy lifestyle. This strategy is of particular importance when considering the global human aging and that the brain suffers significantly from the life-long impact of stress factors.

Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder and studies have found it to be associated with nutrient deficiencies, namely magnesium and vitamin D. The aim of this randomized, controlled study is to assess the effect of vitamin D and magnesium supplementation on mental health and behavioral outcomes in children with ADHD. Sixty-six children with ADHD were randomly allocated to receive both vitamin D plus magnesium or placebo for eight weeks, and a validated children’s mental health questionnaire was assessed. After eight weeks, serum vitamin D and magnesium, as well as various behavioural outcomes (emotional problem, peer problem, total difficulties and internalising), were all significantly improved among the treatment group compared to placebo. Based on these results, the authors conclude co-supplementing vitamin D and magnesium can improve the behavioral function and mental health of children with ADHD. They suggest larger, well-designed studies are needed to both validate these findings and further explore whether micronutrient deficiencies in ADHD are a cause or effect of the disorder.
Abstract
BACKGROUND Attention-Deficit / Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder, characterized by varying severity in attention deficit and hyperactivity. Studies have shown deficiencies in the serum level of magnesium and vitamin D in people with ADHD. The aim of this study is to determine the effect of vitamin D and magnesium supplementation on mental health in children with ADHD. METHODS We conducted a randomized, double blind, placebo-controlled clinical trial of 66 children with ADHD. Participants were randomly allocated to receive both vitamin D (50,000 IU/week) plus magnesium (6 mg/kg/day) supplements (n = 33) or placebos (n = 33) for 8-weeks. Strengths and difficulties questionnaire was used to evaluate children's mental health at baseline and the end of the study. RESULTS After eight weeks of intervention, the serum levels of 25-hydroxy-vitamin D3 and magnesium increased significantly in the intervention group compared with the control group. Also, children receiving vitamin D plus magnesium showed a significant reduction in emotional problems (p = 0.001), conduct problems (p = 0.002), peer problems (p = 0.001), prosocial score (p = 0.007), total difficulties (p = 0.001), externalizing score (p = 0.001), and internalizing score (p = 0.001) compared with children treated with the placebo. CONCLUSION Vitamin D (50,000 IU/week) and magnesium (6 mg/kg/day) co-supplementation for a duration of 8-weeks could improve the behavioral function and mental health of children with ADHD. However, further well-designed studies with a larger sample size are needed. TRIAL REGISTRATION IRCT2016030326886N1 .

Plain language summary
Acute respiratory tract infections are a major cause of morbidity and mortality across the globe with seasonal influenza epidemics and outbreaks of viruses, such as Covid-19. The authors support public hygiene practices and the development of vaccinations however call for further strategies in order to reduce the impact that these infections have on societies. The role nutrition plays in supporting the immune system is well established. This review article and opinion piece presents the evidence for Vitamins A, B6, B12, C, D, E and folate; trace elements including zinc, selenium, magnesium and copper; and omega-3 fatty acids in supporting the immune system. The authors call for the consumption of a well-balanced diet, with additional supplementation of key immune supportive nutrients. Well referenced and with a helpful table of the rationale and recommended nutrient intake levels, Nutrition Practitioners will find this article useful when working to support client immune health.
Abstract
Public health practices including handwashing and vaccinations help reduce the spread and impact of infections. Nevertheless, the global burden of infection is high, and additional measures are necessary. Acute respiratory tract infections, for example, were responsible for approximately 2.38 million deaths worldwide in 2016. The role nutrition plays in supporting the immune system is well-established. A wealth of mechanistic and clinical data show that vitamins, including vitamins A, B6, B12, C, D, E, and folate; trace elements, including zinc, iron, selenium, magnesium, and copper; and the omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid play important and complementary roles in supporting the immune system. Inadequate intake and status of these nutrients are widespread, leading to a decrease in resistance to infections and as a consequence an increase in disease burden. Against this background the following conclusions are made: (1) supplementation with the above micronutrients and omega-3 fatty acids is a safe, effective, and low-cost strategy to help support optimal immune function; (2) supplementation above the Recommended Dietary Allowance (RDA), but within recommended upper safety limits, for specific nutrients such as vitamins C and D is warranted; and (3) public health officials are encouraged to include nutritional strategies in their recommendations to improve public health.

Plain language summary
Fibromyalgia (FM) is a chronic pain condition, often presenting with widespread body pain, joint stiffness, sleep disorders, depression, anxiety, gastrointestinal and cognitive complaints. Despite being common, the cause of FM is not well understood. In the absence of effective treatments, the current management of FM involves a multidisciplinary approach utilizing pharmacological and non-pharmacological interventions. Growing evidence suggests a role for nutrition as a complementary strategy for FM management. This brief review summarises the possible impact of nutritional supplements and dietary interventions on FM. Previous reviews concluded that vitamin and mineral deficiencies themselves are unlikely to be significant in the development of FM. Yet, a few interventional studies investigating the use of Vitamin D, magnesium, iron and probiotics showed promising results. To date, there is no or limited evidence for the use of Vitamin C, E, selected amino acids, botanical or antioxidant supplements. Food-wise the inclusion of quality olive oil and the grain Khorasan proved helpful on FM presentation, whilst findings around the role of dietary monosodium glutamate and aspartame seem mixed. Regarding diet patterns, gluten-free, low-calorie, vegetarian, vegan, raw food or Mediterranean diets were all associated with improvement of symptoms. Equally a FODMAP diet can aid FM associated digestive complaints due to the significant overlap of Irritable Bowel Syndrome with FM. The authors concluded that the clinical application of dietary supplements in the management of FM remains controversial. Yet, dietary interventions appear to be an effective tool in the management of FM. Since various diet interventions demonstrated benefits, dietary adequacy and weight loss may be most critical from a clinical perspective.
Abstract
Fibromyalgia (FM) is a multifactorial syndrome of unknown etiology, characterized by widespread chronic pain and various somatic and psychological manifestations. The management of FM requires a multidisciplinary approach combining both pharmacological and nonpharmacological strategies. Among nonpharmacological strategies, growing evidence suggests a potential beneficial role for nutrition. This review summarizes the possible relationship between FM and nutrition, exploring the available evidence on the effect of dietary supplements and dietary interventions in these patients. Analysis of the literature has shown that the role of dietary supplements remains controversial, although clinical trials with vitamin D, magnesium, iron and probiotics' supplementation show promising results. With regard to dietary interventions, the administration of olive oil, the replacement diet with ancient grains, low-calorie diets, the low FODMAPs diet, the gluten-free diet, the monosodium glutamate and aspartame-free diet, vegetarian diets as well as the Mediterranean diet all appear to be effective in reducing the FM symptoms. These results may suggest that weight loss, together with the psychosomatic component of the disease, should be taken into account. Therefore, although dietary aspects appear to be a promising complementary approach to the treatment of FM, further research is needed to provide the most effective strategies for the management of FM.

Plain language summary
Minerals and trace elements (MTEs) are involved in hundreds of biological processes, and according to available population data many recommended amounts of MTEs are not being met. While MTEs are known to impact processes that are related to athletic performance, there is no consensus as to the efficacy of MTE supplementation and improved performance. The aim of this systematic review was to critically analyse the available evidence on MTE supplementation for enhancing athletic performance. According to 128 studies that met the inclusion criteria, iron and magnesium were the only two that demonstrated benefits. Based on the existing literature, the authors conclude there is insufficient evidence to suggest guidelines of MTEs to enhance athletic performance, and encourage high quality studies to investigate this further.
Abstract
Minerals and trace elements (MTEs) are micronutrients involved in hundreds of biological processes. Deficiency in MTEs can negatively affect athletic performance. Approximately 50% of athletes have reported consuming some form of micronutrient supplement; however, there is limited data confirming their efficacy for improving performance. The aim of this study was to systematically review the role of MTEs in exercise and athletic performance. Six electronic databases and grey literature sources (MEDLINE; EMBASE; CINAHL and SportDISCUS; Web of Science and clinicaltrials.gov) were searched, in accordance with PRISMA guidelines. Results: 17,433 articles were identified and 130 experiments from 128 studies were included. Retrieved articles included Iron (n = 29), Calcium (n = 11), Magnesium, (n = 22), Phosphate (n = 17), Zinc (n = 9), Sodium (n = 15), Boron (n = 4), Selenium (n = 5), Chromium (n = 12) and multi-mineral articles (n = 5). No relevant articles were identified for Copper, Manganese, Iodine, Nickel, Fluoride or Cobalt. Only Iron and Magnesium included articles of sufficient quality to be assigned as 'strong'. Currently, there is little evidence to support the use of MTE supplementation to improve physiological markers of athletic performance, with the possible exception of Iron (in particular, biological situations) and Magnesium as these currently have the strongest quality evidence. Regardless, some MTEs may possess the potential to improve athletic performance, but more high quality research is required before support for these MTEs can be given.

Plain language summary
Magnesium is the fourth most abundant positively charged molecule in the human body and is involved as a co-factor in over 300 enzymatic reactions. Magnesium deficiency is commonly seen in clinic settings and intensive care units and is associated with an increased risk of mortality and length of hospital stay. Magnesium deficiency is also associated with a wide range of chronic diseases and is a known side-effect of some commonly used medications, such as proton pump inhibitors. This review study brings together the latest findings in the scientific literature on magnesium. The authors conclude from the literature that magnesium can play a therapeutic and preventative role in conditions such as diabetes mellitus, osteoporosis, asthma, migraine and cardiovascular disease.
Abstract
Magnesium is the fourth most abundant cation in the body. It has several functions in the human body including its role as a cofactor for more than 300 enzymatic reactions. Several studies have shown that hypomagnesemia is a common electrolyte derangement in clinical setting especially in patients admitted to intensive care unit where it has been found to be associated with increase mortality and hospital stay. Hypomagnesemia can be caused by a wide range of inherited and acquired diseases. It can also be a side effect of several medications. Many studies have reported that reduced levels of magnesium are associated with a wide range of chronic diseases. Magnesium can play important therapeutic and preventive role in several conditions such as diabetes, osteoporosis, bronchial asthma, preeclampsia, migraine, and cardiovascular diseases. This review is aimed at comprehensively collating the current available published evidence and clinical correlates of magnesium disorders.

Plain language summary
Type 2 diabetes is rising worldwide and increasing evidence indicates that dietary and lifestyle choices are key drivers of insulin resistance. Research on plant-based diets (PBDs) shows lower rates of type 2 diabetes, obesity, hypertension, hyperlipidaemia, cardiovascular disease and cancer. The aim of this review is to analyze the evidence supporting the use of PBDs for the prevention and treatment of type 2 diabetes and explore potential mechanisms of action. The existing literature points to the fact that PBDs simultaneously reduce the risk factors for cardiovascular disease including obesity, hypertension, hyperlipidaemia and inflammation. The proposed mechanism by which PBDs reduce insulin resistance is through the high fiber, antioxidant and magnesium content, all of which have been shown to promote insulin sensitivity. Based on this analysis, the authors conclude the PBD is highly beneficial for preventing and treating type 2 diabetes. Additionally, the authors agree with the mounting evidence for utilising a PBD to reduce the burden of diabetes and improve health overall.
Abstract
The prevalence of type 2 diabetes is rising worldwide, especially in older adults. Diet and lifestyle, particularly plant-based diets, are effective tools for type 2 diabetes prevention and management. Plant-based diets are eating patterns that emphasize legumes, whole grains, vegetables, fruits, nuts, and seeds and discourage most or all animal products. Cohort studies strongly support the role of plant-based diets, and food and nutrient components of plant-based diets, in reducing the risk of type 2 diabetes. Evidence from observational and interventional studies demonstrates the benefits of plant-based diets in treating type 2 diabetes and reducing key diabetes-related macrovascular and microvascular complications. Optimal macronutrient ratios for preventing and treating type 2 diabetes are controversial; the focus should instead be on eating patterns and actual foods. However, the evidence does suggest that the type and source of carbohydrate (unrefined versus refined), fats (monounsaturated and polyunsaturated versus saturated and trans), and protein (plant versus animal) play a major role in the prevention and management of type 2 diabetes. Multiple potential mechanisms underlie the benefits of a plant-based diet in ameliorating insulin resistance, including promotion of a healthy body weight, increases in fiber and phytonutrients, food-microbiome interactions, and decreases in saturated fat, advanced glycation endproducts, nitrosamines, and heme iron.
