Metabolic syndrome, defined as having high blood pressure, triglycerides, blood glucose and being obese, is becoming an increasing worldwide health problem. It’s considered to be a result of modern-day life styles and there is no effective cure other than diet and life style interventions. This review paper looks at the mineral content and the alkalising effects of mineral water when consumed by participants with metabolic syndrome. The minerals within mineral water are thought to be more readily absorbed in the body than when consumed in foods and since Westernised diets are low in mineral content and high in acidity, consuming mineral water could help counteract mineral deficiencies and help to balance pH in those with metabolic syndrome. 20 studies, both animal and human, were selected for evaluation of the effect of mineral water on blood pressure, lipid profile, blood glucose and waist circumference. The authors conclude that mineral water is indeed beneficial to those with metabolic syndrome and can help counteract mineral deficiencies and balance pH. However, it is unclear whether mineral water in high quantities would be detrimental to a person with adequate mineral status and a pH within optimal range. Further studies are needed.
Abstract
Metabolic syndrome (MetSyn) promotes, among others, the development of atherosclerotic cardiovascular disease and diabetes. Its prevalence increases with age, highlighting the relevance of promoting precocious MetSyn primary prevention and treatment with easy-to-implement lifestyle interventions. MetSyn features modulation through mineral water consumption was reviewed on Pubmed, Scopus and Google Scholar databases, using the following keywords: metabolic syndrome, hypertension, blood pressure (BP), cholesterol, triglycerides, apolipoprotein, chylomicron, very low-density lipoprotein, low-density lipoprotein, high-density lipoprotein (HDL), glucose, insulin, body weight, body mass index, waist circumference (WC), obesity and mineral(-rich) water. Twenty studies were selected: 12 evaluated BP, 13 assessed total-triglycerides and/or HDL-cholesterol, 10 analysed glucose and/or 3 measured WC. Mineral waters were tested in diverse protocols regarding type and composition of water, amount consumed, diet and type and duration of the study. Human and animal studies were performed in populations with different sizes and characteristics. Distinct sets of five studies showed beneficial effects upon BP, total-triglycerides, HDL-cholesterol and glucose. WC modulation was not reported. Minerals/elements and active ions/molecules present in mineral waters (and their pH) are crucial to counterbalance their inadequate intake and body status as well as metabolic dysfunction and increased diet-induced acid-load observed in MetSyn. Study characteristics and molecular/physiologic mechanisms that could explain the different effects observed are discussed. Further studies are warranted for determining the mechanisms involved in the putative protective action of mineral water consumption against MetSyn features.

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
Bone mass attained at the end of adolescence is an important determinant of later osteoporosis risk. Little is known about the influence of dietary patterns on bones during adolescence and their potential long-term implications into adulthood. The aim of this study was to examine the effect of dietary patterns on bone change from adolescence to young adulthood in 125 adolescents and 115 young adults. Bone mineral content and bone mineral density were measured, and dietary intake from multiple 24-hour recalls were collected. Five dietary patterns were found including vegetarian style, western-like, high-fat high protein, mixed and snack. This study found that a vegetarian style diet during adolescence is positively associated with bone health. Based on these results, the authors conclude bone accrual in adolescence can be carried into young adulthood, and suggest further studies are needed to generalise these results to wider populations.
Abstract
BACKGROUND The amount of bone accrued during adolescence is an important determinant of later osteoporosis risk. Little is known about the influence of dietary patterns (DPs) on the bone during adolescence and their potential long-term implications into adulthood. We examined the role of adolescent DPs on adolescent and young adult bone and change in DPs from adolescence to young adulthood. METHODS We recruited participants from the Saskatchewan Pediatric Bone Mineral Accrual Study (1991-2011). Data from 125 participants (53 females) for adolescent analysis (age 12.7 ± 2 years) and 115 participants (51 females) for adult analysis (age 28.2 ± 3 years) were included. Bone mineral content (BMC) and areal bone mineral density (aBMD) of total body (TB), femoral neck (FN) and lumbar spine (LS) were measured using dual-energy X-ray absorptiometry. Adolescent dietary intake data from multiple 24-h recalls were summarized into 25 food group intakes and were used in the principal component analysis to derive DPs during adolescence. Associations between adolescent DPs and adolescent or adult BMC/BMD were analyzed using multiple linear regression and multivariate analysis of covariance while adjusting for sex, age, the age of peak height velocity, height, weight, physical activity and total energy intake. Generalized estimating equations were used for tracking DPs. RESULTS We derived five DPs including "Vegetarian-style", "Western-like", "High-fat, high-protein", "Mixed" and "Snack" DPs. The "Vegetarian-style" DP was a positive independent predictor of adolescent TBBMC, and adult TBBMC, TBaBMD (P < 0.05). Mean adolescent TBaBMD and young adult TBBMC, TBaBMD, FNBMC and FNaBMD were 5%, 8.5%, 6%, 10.6% and 9% higher, respectively, in third quartile of "Vegetarian-style" DP compared to first quartile (P < 0.05). We found a moderate tracking (0.47-0.63, P < 0.001) in DP scores at individual levels from adolescence to adulthood. There were an upward trend in adherence to "Vegetarian-style" DP and an downward trend in adherence to "High-fat, high-protein" DP from adolescence to young adulthood (P < 0.01). CONCLUSION A "Vegetarian-style" DP rich in dark green vegetables, eggs, non-refined grains, 100% fruit juice, legumes/nuts/seeds, added fats, fruits and low-fat milk during adolescence is positively associated with bone health.

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.
