Dietary Strategies:
Abstract: Metabolic syndrome (MetS) is established as the combination of central obesity and different metabolic disturbances, such as insulin resistance, hypertension and dyslipidemia. This cluster of factors affects approximately 10%�50% of adults worldwide and the prevalence has been increasing in epidemic proportions over the last years. Thus, dietary strategies to treat this heterogenic disease are under continuous study. In this sense, diets based on negative-energy-balance, the Mediterranean dietary pattern, n-3 fatty acids, total antioxidant capacity and meal frequency have been suggested as effective approaches to treat MetS. Furthermore, the type and percentage of carbohydrates, the glycemic index or glycemic load, and dietary fiber content are some of the most relevant aspects related to insulin resistance and impaired glucose tolerance, which are important co-morbidities of MetS. Finally, new studies focused on the molecular action of specific nutritional bioactive compounds with positive effects on the MetS are currently an objective of scientific research worldwide. The present review summarizes some of the most relevant dietary approaches and bioactive compounds employed in the treatment of the MetS to date.

Contents
Obesity consists of an abnormal or excessive fat accumulation, for which the main cause is a chronic imbalance between energy intake and energy expenditure [7,8]. The excess of energy consumed is primarily deposited in the adipose tissue as triglycerides (TG) [9].
Dyslipidemia encompasses elevated serum TG levels, increased low density lipoprotein- cholesterol (LDL-c) particles, and reduced levels of high density lipoprotein-cholesterol (HDL-c) [10]. It is associated with hepatic steatosis [11], dysfunction of pancreatic ?-cells [12] and elevated risk of atherosclerosis [13], among others.
Another main modifiable MetS manifestation is hypertension, which is mainly defined as a resting systolic blood pressure (SBP) ? 140 mmHg or diastolic blood pressure (DBP) ? 90 mmHg or drug prescription to lower hypertension [14]. It usually involves narrowed arteries and is identified as a major cardiovascular and renal risk factor, related to heart and vascular disease, stroke and myocardial infarction [13,15�17].
Hyperglycemia, related insulin resistance and type 2 diabetes mellitus are characterized by an impaired uptake of glucose by the cells, that lead to elevated plasma glucose levels, glycosuria and ketoacidosis [18]. It is responsible for different tissue damage that shortens the life expectancy of diabetics, involving cardiovascular diseases (CVD), atherosclerosis, hypertension [19], ?-cell dysfunction [12], kidney disease [20] or blindness [21]. Currently, diabetes is considered the leading cause of death in developed countries [22].
Moreover, oxidative stress and low grade inflammation are two important mechanisms implicated in the etiology, pathogenesis, and development of MetS [23]. Oxidative stress is defined as an imbalance between the pro-oxidants and antioxidants in the body [24]. It plays a key role in the development of atherosclerosis by different mechanisms such as the oxidation of LDL-c particles [25] or impairment of HDL-c functions [26]. Inflammation is an immune system response to injury hypothesized to be a major mechanism in the pathogenesis and progression of obesity related disorders and the link between adiposity, insulin resistance, MetS and CVD [27].
Although the prevalence of the MetS varies broadly around the word and depends on the source used for its definition, it is clear that over the last 40�50 years the number of people presenting with this syndrome has risen in epidemic proportions [28]. Moreover, the frequency of this syndrome is increased in developed countries, sedentary people, smokers, low socioeconomic status population, as well as in individuals with unhealthy dietary habits [29,30].
For all of this, there is currently a wide concern to find effective strategies to detect, treat and control the comorbidities associated with MetS. This is a complex challenge as MetS is a clinical entity of substantial heterogeneity and therefore, the different cornerstones implicated in its development should be addressed. In this review we compiled and examined different dietary patterns and bioactive compounds that have pointed out to be effective in MetS treatment.
Energy restricted diets are probably the most commonly used and studied dietary strategies for combating excess weight and related comorbidities. They consist in personalized regimes that supply less calories than the total energy expended by a specific individual [31].
A hypocaloric diet results in a negative energy balance and subsequently, in body weight reduction [31]. Weight loss is achieved via fat mobilization from different body compartments as a consequence of the lipolysis process necessary to provide energy substrate [32,33]. In people who are overweight or suffering from obesity, as is the case of most people with MetS, weight loss is important as it is associated with improvement of related disorders such as abdominal obesity (visceral adipose tissue), type 2 diabetes, CVD or inflammation [32�36].
Moreover, as described above, low grade inflammation is associated with MetS and obesity. Therefore, of particular importance is the fact that in obese individuals following a hypocaloric diet, a depletion of plasma inflammatory markers such as interleukin (IL)-6 has been observed [34]. Thus, caloric restriction in obese people suffering MetS may improve the whole-body pro-inflammatory state.
At the same time, body weight reduction is associated with improvements in cellular insulin signal transduction, increments in peripheral insulin sensitivity and higher robustness in insulin secretory responses [32,36]. People with excess body weight who are at risk of developing type 2 diabetes, may benefit from a hypocaloric regime by improving plasma glucose levels and insulin resistance.
In addition, different intervention trials have reported a relationship between energy restricted diets and lower risk of developing CVD. In this sense, in studies with obese people following a hypocaloric diet, improvements in lipid profile variables such as reductions of LDL-c and plasma�TG levels, as well as improvements in hypertension via depletion of SBP and DBP levels have been observed [35,37].
Among the different nutritional intervention trials, a reduction of 500�600 kcal a day of the energy requirements is a well-established hypocaloric dietary strategy, which has demonstrated to be effective in weight reduction [38,39]. However, the challenge lies in maintaining the weight loss over time, as many subjects can follow a prescribed diet for a few months, but most people have difficulty in maintaining the acquired habits over the long term [40,41].
There is a moderate body of evidence suggesting that n-3 PUFAs, mainly EPA and DHA, have a positive role in the prevention and treatment of the pathologies associated to MetS [42].
In this context, it has been described that EPA and DHA have the ability to reduce the risk of developing CVD and cardiometabolic abnormalities as well as CVD-related mortality [42]. These beneficial effects are thought to be mainly due to the ability of these essential fatty acids to reduce plasma TG levels [43].
Moreover, different studies have shown that people following an increased n-3 PUFA diet have reduced plasma levels of the pro-inflammatory cytokines IL-6 and tumor necrosis factor-alpha (TNF?), as well as plasma C-reactive protein (CRP) [44]. These effects are probably mediated by resolvins, maresins and protectins, which are EPA and DHA metabolic products with anti-inflammatory properties [44].
There are some studies that have observed an association between n-3 ingestion and improvements or prevention of type 2 diabetes development. However, other studies found opposite results [44]. Thus, it cannot be made any specific affirmation in this respect.
The European Food Safety Authority recommends and intake of 250 mg EPA + DHA a day, in the general healthy population as a primary prevention of CVD [45]. These amounts can be achieved with an ingestion of 1�2 fatty fish meals per week [45].
There is a theory which states that MetS is a consequence of an elevated intake of high GI foods over time, among others unhealthy dietary habits [49]. In this sense, following a diet rich in high GI CHO has been associated with hyperglycemia, insulin resistance, type 2 diabetes, hypertriglyceridemia, CVD, and obesity [47,50,51], abnormalities directly related to MetS.
On the contrary, a low GI diet has been associated with slower absorption of the CHO and subsequently smaller blood glucose fluctuations, which indicate better glycemic control [46]. In patients with type 2 diabetes, diets based on low GI are associated with reductions in glycated hemoglobin (HbA1c) and fructosamine blood levels, two biomarkers used as key monitoring factors in diabetes management [52,53].
For all of this, it is common to find the limitation of CHO at high GI among the advice for MetS treatment [28], in particular with respect to �ready-to-eat processed foods� including sweetened beverages, soft drinks, cookies, cakes, candy, juice drinks, and other foods which contain high amounts of added sugars [54].
In this sense, the World Health Organization (WHO) recommendation for fruit and vegetables consumption (high TAC foods) for the general population is a minimum of 400 g a day [66]. Moreover, cooking with spices is recommended in order to increase the TAC dietary intake and, at the same time, maintain flavor while reducing salt [67].
Two mechanisms have been proposed to explain the potential beneficial effects of high-moderate protein diets: the increment of diet-induced thermogenesis [73] and the increase of satiety [78]. The increment of the thermogenesis is explained by the synthesis of peptide bonds, production of urea and gluconeogenesis, which are processes with a higher energy requirement than the metabolism of lipids or CHO [75]. An increment of different appetite-control hormones such as insulin, cholecystokinin or glucagon-like peptide 1, may clarify the satiety effect [79].
Other beneficial effects attributed to moderate-high protein diets in the literature are the improvement of glucose homeostasis [80], the possibility of lower blood lipids [81], the reduction of blood pressure [82], the preservation of lean body mass [83] or the lower of cardiometabolic disease risk [84,85]. However, there are other studies that have not found benefits associated to a moderate-high protein diet [76]. This fact may be explained by the different type of proteins and their amino acid composition [80], as well as by the different type of populations included in each study [85]. Therefore, more research in the field is needed in order to make these results consistent.
In any case, when a hypocaloric diet is implemented, it is necessary to slightly increase the amount of proteins. Otherwise it would be difficult to reach the protein energy requirements, established as 0.83 g/kg/day for isocaloric diets and which should probably be at least 1 g/kg/day for energy-restricted diets [86].
The pattern of increasing meal frequency in weight loss and weight control interventions has currently become popular among professionals [87,88]. The idea is to distribute the total daily energy�intake into more frequently and smaller meals. However, there is no strong evidence about the efficacy of this habit yet [89]. While some investigations have found an inverse association between the increment of meals per day and body weight, body mass index (BMI), fat mass percentage or metabolic diseases such as coronary heart disease or type 2 diabetes [71,88,90�92], others have found no association [93�95].
Different mechanisms by which high meal frequency can have a positive effect on weight and metabolism management have been proposed. An increment of energy expenditure was hypothesized; however, the studies carried out in this line have concluded that total energy expenditure does not differ among different meal frequencies [96,97]. Another postulated hypothesis is that the greater the number of meals a day, the higher the fat oxidation, but again no consensus has been achieved [89,98]. An additional suggested mechanism is that increasing meal frequency leads to plasma glucose levels with lower oscillations and reduced insulin secretion which is thought to contribute to a better appetite control. However, these associations have been found in population with overweight or high glucose levels but in normal-weight or normoglycaemic individuals the results are still inconsistent [93,99�101].
The traditional MedDiet is characterized by a high intake of extra-virgin olive oil and plant foods (fruits, vegetables, cereals, whole grains, legumes, tree nuts, seeds and olives), low intakes of sweets and red meat and moderate consumption of dairy products, fish and red wine [104].
There is a lot of literature supporting the general health benefits of the MedDiet. In this sense, it has been reported that a high adherence to this dietary pattern protects against mortality and morbidity from several causes [105]. Thus, different studies suggested the MedDiet as a successful tool for the prevention and treatment of MetS and related comorbidities [106�108]. Moreover, recent meta-analysis concluded that the MedDiet is associated with less risk of developing type 2 diabetes and with a better glycemic control in people with this metabolic disorder [107,109,110]. Other studies have found a positive correlation between the adherence to a MedDiet pattern and reduced risk of developing CVD [111�114]. In fact, many studies have found a positive association between following a MedDiet and improvements in lipid profile by reduction of total cholesterol, LDL-c and TG, and an increase in HDL-c [111�115]. Finally, different studies also suggest that the MedDiet pattern may be a good strategy for obesity treatment as it has been associated with significant reductions in body weight and waist circumference [108,116,117].
The high amount of fiber which, among other beneficial effects, helps to weight control providing satiety; and the high antioxidants and anti-inflammatory nutrients such as n-3 fatty acids, oleic acid or phenolic compounds, are thought to be the main contributors to the positive effects attributed to the MedDiet [118].
For all these reasons, efforts to maintain the MedDiet pattern in Mediterranean countries and to implement this dietary habits in westernized countries with unhealthy nutritional patterns should be made.
This dietary component produces its antioxidant effect primarily by quenching damaging free radicals and other reactive oxygen and nitrogen species and therefore preventing molecules such as LDL-c from oxidation [122]. It can also regenerate other oxidized antioxidants like tocopherol [124].
Moreover, it has been described that ascorbic acid may reduce inflammation as it is associated with depletion of CRP levels [125]. This is an important outcome to take in consideration in the treatment of MetS sufferers, as they usually present low grade inflammation [27].
Supplementation with vitamin C have also been associated with prevention of CVD by improving the endothelial function [126] and probably by lowering blood pressure [121]. These effects are thought to be exerted by the ability of vitamin C to enhance the endothelial nitric oxide synthase enzyme (eNOS) activity and to reduce HDL-c glycation [127].
Additionally, several studies have attributed to ascorbate supplementation an antidiabetic effect by improving whole body insulin sensitivity and glucose control in people with type 2 diabetes [123]. These antidiabetic properties are thought to be mediated by optimization of the insulin secretory function of the pancreatic islet cells by increasing muscle sodium-dependent vitamin C transporters (SVCTs) [128].
Despite all of this, it should be taken into account that most people reach ascorbic acid requirements (established at 95�110 mg/day in the general population) from diet and do not need supplementation [122,129]. Besides, it should be considered that an excess of vitamin C ingestion leads to the opposite effect and oxidative particles are formed [130,131].
It is considered the strongest antioxidant of olive oil and one of the main antioxidants in nature [133]. It acts as a powerful scavenger of free radicals, as a radical chain breaker and as metal chelator [134]. It has the ability of inhibiting LDL-c oxidation by macrophages [132]. In this sense, it is the only phenol recognized by the European Food Safety Authority (EFSA) as a protector of blood lipids from oxidative damage [135].
Hydroxytyrosol has also been reported to have anti-inflammatory effects, probably by suppressing cyclooxygenase activity and inducing eNOS expression [136]. Thus, enhancement of olives/olive oil intakes or hydroxytyroxol supplementation in people suffering from MetS may be a good strategy in order to improve inflammatory status.
Another beneficial effect attributed to this phenolic compound is its cardiovascular protective effect. It presents anti-atherogenic properties by decreasing the expression of vascular cell adhesion protein 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1) [132,137], which are probably the result of an inactivation of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF?B), activator protein 1 (AP-1), GATA transcription factor and nicotinamide adenine dinucleotide phosphate (NAD(P)H) oxidase [138,139]. Hydroxytyrosol also provides antidyslipidemic effects by lowering plasma levels of LDL-c, total cholesterol and TG, and by rising HDL-c [138].
Despite the beneficial effects attributed to hydfroxytyrosol as an antioxidant, for its antiinflamatory properties and as cardiovascular protector, it should be taken into account that most studies focused on this compound have been performed with mixtures of olive phenols, thus a synergic effect cannot be excluded [140].
Many beneficial effects that can contribute to MetS improvement have been attributed to quercetin. Among them, its antioxidant capacity should be highlighted, as it has been reported to inhibit lipid peroxidation and increase antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) or glutathione peroxidase (GPX) [142].
Moreover, an anti-inflammatory effect mediated via attenuation of tumor necrosis factor ? (TNF-?), NF?B and mitogen-activated protein kinases (MAPK), as well as depletion of IL-6, IL-1?, IL-8 or monocyte chemoattractant protein-1 (MCP-1) gene expression has also been attributed to this polyphenol [143].
As most people with MetS are overweight or obese, the role of quercetin in body weight reduction and obesity prevention has been of special interest. In this sense, it stands out the capacity of quercetin to inhibit adipogenesis through inducing the activation of AMP-activated protein kinase (AMPK) and decreasing the expression of CCAAT-enhancer-binding protein-? (C/EBP?), peroxisome�proliferator-activated receptor gamma (PPAR?), and sterol regulatory element-binding protein 1 (SREBP-1) [141,144].
According to the antidiabetic effects, it is proposed that quercetin may act as an agonist of peroxisome proliferator-activated receptor gamma (PPAR?), and thus improve insulin-stimulated glucose uptake in mature adipocytes [145]. Moreover, quercetin may ameliorate hyperglycemia by inhibiting glucose transporter 2 (GLUT2) and insulin dependent phosphatidylinositol-3-kinase (PI3K) and blocking tyrosine kinase (TK) [142].
Finally, different studies observed that quercetin has the ability to reduce blood pressure [146�148]. However, the mechanisms of action are not clear, since some authors have suggested that quercetin increases eNOS, contributing to inhibition of platelet aggregation and improvement of the endothelial function [146,147], but there are other studies that have not come across these results [148].
Resveratrol (3,5,4?-trihidroxiestilben) is a phenolic compound mainly found in red grapes and derived products (red wine, grape juice) [149]. It has shown antioxidant and anti-inflammatory activities, and cardioprotective, anti-obesity and antidiabetic capacities [150�156].
The antioxidant effects of resveratrol have been reported to be carried out by scavenging of hydroxyl, superoxide, and metal-induced radicals as well as by antioxidant effects in cells producing reactive oxygen species (ROS) [150].
Moreover, it has been reported that the anti-inflammatory effects of resveratrol are mediated by inhibiting NF?B signaling [151]. Furthermore, this polyphenol reduces the expression of proinflammatory cytokines such as interleukin 6 (IL-6), interleukin 8 (IL-8), TNF-?, monocyte chemoattractant protein-1 (MCP-1) and eNOS [152]. In addition, resveratrol inhibits the cyclooxygenase (COX) expression and activity, a pathway involved in the synthesis of proinflammatory lipid mediators [152].
Concerning the effects of resveratrol against development of type 2 diabetes, it has been reported that treatment of diabetes patients with this polyphenol provides significant improvements in the status of multiple clinically relevant biomarkers such as fasting glucose levels, insulin concentrations or glycated hemoglobin and Homeostasis Model Assessment Insulin Resistance (HOMA-IR) [153,154].
Additionally, cardioprotective effects have been attributed to resveratrol. In this sense, it is suggested that resveratrol improves the endothelial function by producing nitric oxide (NO) through increasing the activity and expression of eNOS. This effect is thought to be conducted through activation of nicotinamide adenine dinucleotide-dependent deacetylase sirtuin-1 (Sirt 1) and 5? AMP-activated protein kinase (AMPK) [155]. Besides, resveratrol exerts endothelial protection by stimulation of NF-E2-related factor 2 (Nrf2) [156] and decreasing the expression of adhesion proteins such as ICAM-1 and VCAM-1 [152].
Finally, it has been described that resveratrol may have a role in preventing obesity as it has been related with energy metabolism improvement, increasing lipolysis and reducing lipogenesis [157]. However, more studies are needed in order to corroborate these findings.
For a long time, it has been suggested that vitamin E could prevent different metabolic diseases as a potent antioxidant, acting as scavenger of lipid peroxyl radicals by hydrogen donating [159]. In this sense, it was described that tocopherols inhibit peroxidation of membrane phospholipids and prevent generation of free radicals in cell membranes [160].
Moreover, it has been shown that supplementation with ?-tocopherol or ?-tocopherol, two of the different isoforms of vitamin E, could have an effect on inflammation status by reducing CRP levels [161]. Additionally, inhibition of COX and protein kinase C (PKC) and reduction of cytokines�such as IL-8 or plasminogen activator inhibitor-1 (PAI-1) are other mechanisms that may contribute to these anti-inflammatory effects [162,163].
However, the beneficial effects attributed to this vitamin previously have lately became controversial as different clinical trials have not come across such benefits, but ineffective or even harmful effects have been observed [164]. It has been recently suggested that this may be explained by the fact that vitamin E may lose most of the antioxidant capacity when ingested by human beings through different mechanisms [162].
Anthocyanins are water-soluble polyphenolic compounds responsible for the red, blue and purple colors of berries, black currants, black grapes, peaches, cherries, plums, pomegranate, eggplant, black beans, red radishes, red onions, red cabbage, purple corn or purple sweet potatoes [165�167]. Actually, they are the most abundant polyphenols in fruits and vegetables [167]. Moreover, they can also be found in teas, honey, nuts, olive oil, cocoa, and cereals [168].
These compounds have high antioxidant capacity inhibiting or decreasing free radicals by donating or transferring electrons from hydrogen atoms [167].
Regarding clinical studies, it has been shown that these bioactive compounds may prevent type 2 diabetes development by improving insulin sensitivity [169]. The exact mechanisms by which anthocyanins exert their antidiabetic effect are not yet clear, but an enhancement of the glucose uptake by muscle and adipocyte cells in an insulin-independent manner has been suggested [169].
Moreover, it has been shown that anthocyanins may have the capacity to prevent CVD development by improving endothelial function via increasing brachial artery flow-mediated dilation and HDL-c, and decreasing serum VCAM-1 and LDL-c concentrations [170�173].
Finally, these polyphenolic compounds may exert anti-inflamatory effects via reducing proinflamatory molecules such as IL-8, IL-1? or CRP [172,174].
However, most studies have used anthocyanin-rich extracts instead of purified anthocyanins; thus, a synergic effect with other polyphenols cannot be discarded.
Anti-obesity effects have been attributed to these polyphenols in different studies [176]. The mechanisms of action suggested to explain these beneficial effects on body weight are: increasing energy expenditure and fat oxidation, and reducing fat absorption [177]. It is thought that energy expenditure is enhanced by catechol-O-methyltransferase and phosphodiesterase inhibition, which stimulates the sympathetic nervous system causing an activation of the brown adipose tissue [178]. Fat oxidation is mediated by upregulation of acyl-CoA dehydrogenase and peroxisomal b-oxidation enzymes [178,179].
Moreover, catechin intake has also been associated with lower risk of CVD development by improving lipid biomarkers. Thus, it has been reported that consumption of this kind of polyphenols may increase HDL-c and decrease LDL-c and total cholesterol [180].
Finally, and antidiabetic effect has also been related to catechin comsumption, lowering fasting glucose levels [175] and improving insulin sensitivity [178].
As the prevalence of MetS reaches epidemic rates, the finding of an effective and easy-to-follow dietary strategy to combat this heterogenic disease is still a pending subject. This work recompiled different dietary nutrients and nutritional patterns with potential benefits in the prevention and�treatment of MetS and related comorbidities (Figure 1) with the aim of facilitating future clinical�studies in this area. The challenge now is to introduce precision bioactive compounds in personalized�nutritional patterns in order to gain the most benefits for prevention and treatment of this disease�through nutrition.
