Abstract
Lithium compounds have been widely used in psychopharmacology, particularly in the treatment of bipolar disorder. Their normothymic and neuroprotective properties when used at high doses have been well established. However, a number of observations suggest that environmentally relevant lithium doses may also exert beneficial health effects, leading to a decrease in the rate of suicides and levels of violence. Despite the fact that this element is not officially considered to be a micronutrient, some authors have suggested provisional recommended intakes set at 1000 μg/day for a 70-kg adult (14.3 μg/kg body weight). The present paper reviews the biological action of lithium, its bioavailability and metabolism, and content in different foodstuffs and water. It also assesses epidemiological data on potential correlations between lithium intake and suicide rate as well as examines the concept of fortifying food with this element as a strategy in the primary prevention of mood disorders and pre-suicidal syndrome.

Abstract
The hierarchical information flow through DNA-RNA-protein-metabolite collectively referred to as 'molecular fingerprint' defines both health and disease. Environment and food (quality and quantity) are the key factors known to affect the health of an individual. The fundamental concepts are that the transition from a healthy condition to a disease phenotype must occur by concurrent alterations in the genome expression or by differences in protein synthesis, function and metabolites. In other words, the dietary components directly or indirectly modulate the molecular fingerprint and understanding of which is dealt with nutrigenomics. Although the fundamental principles of nutrigenomics remain similar to that of traditional research, a collection of comprehensive targeted/untargeted data sets in the context of nutrition offers the unique advantage of understanding complex metabolic networks to provide a mechanistic understanding of data from epidemiological and intervention studies. In this review the challenges and opportunities of nutrigenomic tools in addressing the nutritional problems of public health importance are discussed. The application of nutrigenomic tools provided numerous leads on biomarkers of nutrient intake, undernutrition, metabolic syndrome and its complications. Importantly, nutrigenomic studies also led to the discovery of the association of multiple genetic polymorphisms in relation to the variability of micronutrient absorption and metabolism, providing a potential opportunity for further research toward setting personalized dietary recommendations for individuals and population subgroups.

Dietary intervention with a specific micronutrient combination for the treatment of patients with cardiac arrhythmias: the impact on insulin resistance and left ventricular function.
Parsi, E, Bitterlich, N, Winkelmann, A, Rösler, D, Metzner, C
BMC cardiovascular disorders. 2018;(1):220
Abstract
BACKGROUND Cardiac arrhythmias (CA) are very common and may occur with or without heart disease. Causes of these disturbances can be components of the metabolic syndrome (MetS) or deficits of micronutrients especially magnesium, potassium, B vitamins and coenzyme Q10. Both causes may also influence each other. Insulin resistance (IR) is a risk factor for diastolic dysfunction. One exploratory outcome of the present pilot study was to assess the impact of a dietary intervention with specific micronutrients on the lowering of IR levels in patients with CA with the goal to improve the left ventricular (LV) function. METHODS This was a post hoc analysis of the randomized double blind, placebo-controlled pilot study in patients with CA (VPBs, SVPBs, SV tachycardia), which were recruited using data from patients who were 18-75 years of age in an Outpatient Practice of Cardiology. These arrhythmias were assessed by Holter ECG and LV function by standard echocardiography. Glucose metabolism was measured by fasting glucose, fasting insulin level and the Homeostasis Model Assessment of IR (HOMA-IR) at baseline and after 6 weeks of dietary supplementation. RESULTS A total of 54 randomized patients with CA received either a specific micronutrient combination or placebo. Dietary intervention led to a significant decrease in fasting insulin ≥58 pmol/l (p = 0.020), and HOMA-IR (p = 0.053) in the verum group after 6 weeks. At the same time, parameters of LV diastolic function were improved after intervention in the verum group: significant reduction of LV mass index (p = 0.003), and in tendency both a decrease of interventricular septal thickness (p = 0.053) as well as an increase of E/A ratio (p = 0.051). On the other hand, the premature beats (PBs) were unchanged under verum. CONCLUSIONS In this pilot study, dietary intervention with specific micronutrient combination as add-on to concomitant cardiovascular drug treatment seems to improve cardio metabolic health in patients with CA. Further studies are required. STUDY REGISTRATION The study was approved by the Freiburg Ethics Commission International and was retrospectively registered with the U.S. National Institutes of Health Clinical Trials gov ID NCT 02652338 on 16 December 2015.

PloS one. 2017;(4):e0175437
Abstract
Different metabolic profiles as well as comorbidities are common in people with Down Syndrome (DS). Therefore it is relevant to know whether micronutrient levels in people with DS are also different. This systematic review was designed to review the literature on micronutrient levels in people with DS compared to age and sex-matched controls without DS. We identified sixty nine studies from January 1967 to April 2016 through main electronic medical databases PubMed, Scopus, and Web of knowledge. We carried out meta-analysis of the data on four essential trace elements (Cu, Fe, Se, and Zn), six minerals (Ca, Cl, K, Mg, Na, and P), and five vitamins (vitamin A, B9, B12, D, and E). People with DS showed lower blood levels of Ca (standard mean difference (SMD) = -0.63; 95% confidence interval (CI): -1.16 to -0.09), Se (SMD = -0.99; 95% CI: -1.55 to -0.43), and Zn (SMD = -1.30; 95% CI: -1.75 to -0.84), while red cell levels of Zn (SMD = 1.88; 95% CI: 0.48 to 3.28) and Cu (SMD = 2.77; 95% CI: 1.96 to 3.57) were higher. They had also higher salivary levels of Ca (SMD = 0.85; 95% CI: 0.38 to 1.33) and Na (SMD = 1.04; 95% CI: 0.39 to 1.69). Our findings that micronutrient levels are different in people with DS raise the question whether these differences are related to the different metabolic profiles, the common comorbidities or merely reflect DS.

The Metabolic Syndrome and the Relevance of Nutrients for its Onset.
Schnack, LL, Romani, AMP
Recent patents on biotechnology. 2017;(2):101-119
Abstract
BACKGROUND Metabolic Syndrome is a pathological condition characterized by the copresence of various dysmetabolic and pathological processes including hypertension, dyslipidemia, type 2 diabetes mellitus, obesity, and cardiovascular complications. Because these conditions manifest themselves differently in a given patient, the ensuing pathophysiological state varies from patient to patient. Consequently, the order in which signs and symptoms manifest themselves can vary, making difficult to establish cause-effect relationship, and efficacious treatment and prevention options. Furthermore, the available therapeutic options do not necessarily apply in an effective manner to all patients due to the modality of the syndrome's onset and progression, and the fact that each patient presents different clinical manifestations. RESULTS Where do the metabolic disturbances originate? Genetic predisposition, maternal health, age, and ethnicity are possible influential factors, which put individuals at higher risk for developing metabolic defects. More recently, dietary factors and deficiency in key macro- and micro-nutrients have been indicated as key players in the onset and progression of the disease. We revised all possible patents applying to this topic. Aside from pharmacological agents used to treat specific medical conditions, no patents were observed to be registered for specific dietary macro- and micro-nutrients. CONCLUSION The present review attempts to provide a framework to help the reader understand the causes behind the development of the metabolic syndrome and its complication.

[Impact of bariatric surgery on the absorption of nutrients in patients with obesity].
Bodunova, NA, Sabel'nikova, EA, Parfenov, AI
Terapevticheskii arkhiv. 2013;(10):98-104
Abstract
The review considers disturbed metabolism of vitamins, minerals, and protein in patients following bariatric surgery. The positive effect of the surgery is proven; however, postresection syndromes that may further occur determine not only a patient follow-up, but also timely therapeutic interventions to prevent hypovitaminoses, anemia, and mineral metabolic disturbances. There are conflicting data on the incidence of these abnormalities. No guidelines for their treatment and prevention have been elaborated.

[Nutrients as inflammatory state modulators].
Kapka-Skrzypczak, L, Niedźwiecka, J, Skrzypczak, M, Kruszewski, M
Pediatric endocrinology, diabetes, and metabolism. 2013;(1):39-43
Abstract
The role of diet in reduction of the risk of chronic diseases such as cardiovascular diseases, diabetes mellitus, obesity, and metabolic syndrome has been widely documented. There is evidence that the link between diet and this kind of diseases is low grade chronic inflammation induced by some nutrients. Inflammation is a natural defense mechanism which helps to avoid tissue injuries caused by biological, physical and chemical factors. Adequate inflammatory process is defined by intensity and duration. As a chronic state (silent inflammation, low grade chronic inflammation), it became an etiologic factor of chronic diseases. References indicate that consumption of some nutrients ? such as fatty acids, glucose, bioactive plant compounds, some vitamins and minerals - is related with enhancement or alleviation of inflammatory state. Including them in diet could help to decrease the risk of chronic diseases and health complications caused by them. The aim of this paper is to show modulation properties of diet due to chronic inflammatory state and short characteristic of chosen components with attributed pro- or anti-inflammatory activity. These properties could be used to formulate diet therapy which could help to reduce inflammatory state and minimalize the risk of chronic diseases.

The role of diet and nutrient composition in nonalcoholic Fatty liver disease.
McCarthy, EM, Rinella, ME
Journal of the Academy of Nutrition and Dietetics. 2012;(3):401-9
Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the developed world. NAFLD is tightly linked to insulin resistance and considered to be the hepatic manifestation of the metabolic syndrome. The cornerstone of any treatment regimen for patients with NAFLD is lifestyle modification focused on weight loss, exercise, and improving insulin sensitivity. Here we review the literature and discuss the role of diet and nutrient composition in the management of NAFLD. Because there are currently no specific dietary guidelines for NAFLD, this review proposes a dietary framework for patients with NAFLD based on the available evidence and extrapolates from dietary guidelines aimed at reducing insulin resistance and cardiovascular risk.

Nutrition and inflammatory bowel disease: primary or adjuvant therapy.
Tighe, MP, Cummings, JR, Afzal, NA
Current opinion in clinical nutrition and metabolic care. 2011;(5):491-6
Abstract
PURPOSE OF REVIEW Our understanding of the importance of nutrition in inflammatory bowel disease (IBD) continues to improve. With increasing evidence or cumulative evidence, this article reviews the current data for the role of nutrition in IBD pathogenesis, disease exacerbation and its use in the treatment of IBD in a clinically relevant context. RECENT FINDINGS Irritable bowel syndrome and obesity prevalence is rising, and is increasingly being recognized in patients with IBD. Exclusive enteral nutrition remains highly relevant because of its efficacy and superior side-effect profile, even when considered against new pharmacological treatments, but requires patient motivation. We are now beginning to understand the importance of micronutrients such as iron and vitamin D, which may not only alter the bowel flora but also have an immune-modulatory effect. More recently, a prebiotic and probiotic combination has been used in a randomized trial for the treatment of IBD. SUMMARY Macronutrient and micronutrient assessment should be an essential part of nutritional assessment of all patients with IBD. Although research is needed to further our understanding of the immune-modulatory effects of nutrients and supplements, better and more effective therapies combining nutrition and drug treatments like immune-suppressants should be explored.

Metabolic management following bariatric surgery.
Strohmayer, E, Via, MA, Yanagisawa, R
The Mount Sinai journal of medicine, New York. 2010;(5):431-45
Abstract
Bariatric surgery is an effective treatment option for obesity. Commonly utilized procedures are either restrictive, malabsorptive, or both. Substantial weight loss can be achieved. Postoperatively, patients experience nutritional, metabolic, and hormonal changes that have important clinical implications. The postoperative diet should be advanced carefully, according to protocol. Micronutrient deficiencies such as vitamin C, vitamin A, and zinc deficiencies are common, especially following malabsorptive procedures. Bone metabolism is greatly affected, in part due to vitamin D deficiency, decreased calcium absorption, and secondary hyperparathyroidism. Diabetes improves acutely in malabsorptive procedures and in sequence with weight loss in restrictive procedures. Polycystic ovarian syndrome improves in nearly all women with this condition who undergo bariatric surgery. Testosterone levels in men also improve after surgery. Consideration of these nutritional, metabolic, and hormonal changes allows for optimal medical management following bariatric surgery.
