Omega- fatty acids for inflammation -

ALA is found in plants and is available in vegetable oils, nuts, flaxseeds, and flaxseed oil, and your body is able to convert a small amount of it to EPA and DHA.

Most Americans do not consume enough food sources to obtain the mg of EPA and DHA that are recommended to affect a change in the inflammatory processes. Increasing mercury levels in some fish like tuna, limits the amount that can be safely ingested. Herrscher and his team at AIR Care can recommend high quality fish oil supplements to meet your specific needs.

Learn the five most common hive triggers and how to treat hive symptoms. These include the production of advanced glycation end products AGEs , increased extracellular superoxide dismutase release, and such proinflammatory cytokine secretions as interleukin-1 beta IL-1 , sialic acid, insulin-like growth factor IGF , C-reactive protein CRP , tumor necrosis factor alpha TNF-α , and matrix metalloproteinase MMP 1 , 3.

One way to accomplish this is to use specialized immunoresolvents molecules, such as resolvins, lipoxins, protectins, and maresins, that mediate the resolution of inflammation 1 , 9 , These mediators trigger the pathways that signal the physiologic end of the acute inflammatory phase in several diseases 9 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , Pro-resolving molecules can be divided into 4 groups.

The first includes lipoxin LX from endogenous metabolism, and arachidonic acid AA , which promotes healing via receptor agonists and controls the resolution phase of acute inflammation 19 , 20 , The second includes resolvins and, more recently, protectins and maresins, which are derivatives of dietary omega-3 polyunsaturated fatty acids PUFAs 1 , 11 , 22 , 23 , It also decreases the likelihood of side effects associated with the conventional anti-inflammatory treatments available 4 , No changes were observed in levels of glutathione GSH , superoxide dismutase SOD or catalase CAT 26 , The PICOS were as follows: P Population , diabetic or CVD patients; I Interventions , any form of omega-3; C Comparisons , any placebo control or a comparison group or diet; O Outcomes , inflammatory biomarkers; and S Study Design , randomized clinical trials.

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses PRISMA guidelines 28 S1 Text. The study protocol is available in the Supporting Information section S2 Text. The protocol was registered prospectively in PROSPERO CRD To be included, randomized controlled studies had to provide information about omega-3 fatty acids, eicosapentaenoic acid EPA , docosahexaenoic acid DHA , or one of the following lipid mediators: lipoxins lipoxin A4, B4 , resolvins resolvin E1, E2, D1 , protectin D1, AT-PD1 , or maresin maresin 1.

Using a search strategy that combined terms see S3 Text , two investigators ZN, WY screened MEDLINE, Web of Science, Embase, the Cochrane Central Register of Controlled Trials, and Scopus,.

In addition, internet search engines e. Any type of treatment that used the previous form of omega-3 fatty acids or mediators was eligible for inclusion in this review, as were all healthcare interventions and outcomes using the focused mediators.

We enhanced the database searches using the following approaches: 1 screening bibliographies of full-text articles included; 2 searching the citations of selected articles on Google Scholar and Web of Science, and 3 contacting authors and experts in the field for additional articles.

Therefore, we did not consider dose-response or noncompliance. We excluded studies that used any omega-3 fatty acids derived from an alpha-linolenic acid ALA , which has different sources and mechanisms. Although our search was not restricted by language, we did not identify any articles that required translation or were in a language unknown to the authors.

We extracted data independently in duplicate ZN, WY. Any discrepancies were resolved through discussion or by a third reviewer when necessary.

The following information was collected: country; study type; lipid mediators; area; total sample size; gender; age; duration; outcome; population; test or control type; dose, and mean and standard deviation SD before and after the intervention, or mean and SD differences.

Two independent authors ZN and WY assessed the quality and discrepancies, which were resolved through discussion. Our conclusions are summarized in the Risk of Bias section S4 Text. A meta-analysis was conducted using mean differences MDs and their SDs for continuous outcomes, or these values were calculated using the data available.

For studies that did not include SDs, a correlation coefficient of 0. The results were combined across studies using a random-effects model. The results were summarized with forest plots using the I-squared I 2 statistic for heterogeneity. The primary outcomes were changes in inflammatory biomarkers across all groups, including LDL, HDL, total cholesterol, TG, HbA1c, Apo AII, CRP, and TNF-α.

The analyses were reported for each disease diabetes and CVD. Sensitivity analyses were attempted based on data availability, results, and the incorporation of aggregate data from different control studies and durations. Funnel plot asymmetry was applied to consider possible publication bias S5 text.

All analyses were conducted using Review Manager RevMan v. Of the unique studies from the combined searches, 44 studies were assessed in full and 16 were deemed eligible Fig.

The following reasons provided a rationale for the exclusion of additional studies 1 each : the authors did not use a randomized control trial RCT ; full access to the article was not possible; all participants were healthy, or aspirin was administered as well S6 Text.

Of the 16 studies eligible, 9 had published data on diabetic patients 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , and 7 had published data on those with CVD 38 , 39 , 40 , 41 , 42 , 43 , The studies were published from to and were conducted throughout the world six in the US, three in Iran, two in the UK, and one each in Australia, Spain, Finland, Israel, and China: S6 Text.

Among these, lipid and inflammatory biomarkers investigated commonly included total cholesterol 11 studies , LDL and TG 10 studies each , and HDL 7 studies. Overall, the findings from the studies included were considered to be at low risk of bias S7 Text. Overall, the majority of inflammatory biomarkers potentially was associated with omega-3 intake compared to different control groups Figs.

Impact of omega-3 fatty acids on total cholesterol, HDL, LDL, and triglycerides among diabetic patients. Impact of omega-3 fatty acids on glucose, fasting blood glucose, and HbA1c among diabetic patients.

However, the levels were not statistically significant. The control group demonstrated significantly improved fasting blood glucose levels compared to the omega-3 group Similar, but nonsignificant, results were seen in glucose The reductions in inflammatory biomarkers varied with different controls.

There was a statistically significant increase in LDL levels in the control group 2. Impact of omega-3 fatty acids on total cholesterol, HDL, LDL, and triglycerides among CVD patients. Compared to different control groups, omega-3 polyunsaturated fatty acids seem to be associated with reductions in the following inflammatory biomarkers: Apo B 1.

When we detected substantial heterogeneity, we planned to conduct a subgroup and sensitivity analysis to explore the possible explanations of the results.

Although there were insufficient data for us to explore subgroups in this review, we planned sensitivity analyses for the inflammatory and lipid outcomes to determine whether the conclusions were sufficiently strong for the decisions made with respect to eligibility and analysis.

We considered whether the review conclusions would have changed if 1 the eligibility was restricted to at least four weeks of follow up, or 2 a specific control group was used.

However, because of insufficient data, we were unable to perform sensitivity analyses in this review, and the quality of the evidence of bias was low overall. Our results indicated that, compared to different control groups, omega-3 polyunsaturated fatty acids are associated statistically significantly with reduced levels of Apo AII, triglycerides, and HDL, as well as improved levels of fasting blood glucose among diabetic patients.

Omega-3 fatty acids also are associated with statistically significant increases in LDL levels among CVD patients. Other biomarkers may experience beneficial reductions with omega-3 use among diabetic or cardiovascular patients.

The ultimate target of any inflammatory process is to clear the insults and leukocytes from lesions and resolve and restore tissue homeostasis The restoration of tissue homeostasis always begins with inflammatory lipid mediators e. The concept of inflammation resolution depends primarily on the active class switch in the mediators from classical prostaglandins and leukotrienes to promising newer immunoresolvents molecules 1.

Endogenous immunoresolvent lipid mediator molecules e. Although lipoxins are derived from different sources than are others arachidonic acid vs. dietary fatty acids, primarily fish oil , together, they all can help inhibit neutrophil recruitment, promote tissue regeneration and the lymphatic removal of phagocytes, and attenuate proinflammatory gene expression 47 , 48 , 49 , 50 , 51 , Several strategies have been used to control diabetes, such as lifestyle changes and eating plans e.

Some studies have introduced omega-3 fatty acids to decrease levels of fasting plasma glucose FPG and improve lipid profiles, inflammatory mediators, and reduce insulin resistance 58 , 59 , However, low dosages of omega-3 fatty acids may have limited effects on insulin resistance, inflammatory markers, and lipid profiles among HIV patients and certain other populations These molecules can have anti-diabetic properties because of improved insulin metabolism and the anti-atherosclerotic and anti-inflammatory effects attributable to the resolution of inflammation, as mentioned previously As a consequence, the reduced proinflammatory mediators on the one hand, and the increased production of anti-inflammatory molecules, such as adiponectin, on the other will improve insulin resistance 46 , 64 , However, omega-3 intake may change the HDL cholesterol subfraction composition and absolute size.

Omega-3 fatty acids also lower triglycerides by reducing the hepatic secretion of VLDL cholesterol Further, it may decrease triglycerides and increase LDL cholesterol in patients with hypertriglyceridemia Our study has shown LDL level increases and triglyceride level reductions.

However, this mechanism remains unclear and some studies have shown neutral effects Thies et al. suggested that another way in which omega-3 fatty acids might act on CVD patients is by stabilizing advanced atherosclerotic plaques and reducing their anti-inflammatory effects thereby However, this study showed that omega-3 fatty acids improved TNF-alpha levels.

Thus, this systematic review summarized all published results of omega-3 fatty acid intake on these aspects. Several investigators have proposed this hypothesis because of their beneficial effects on morphologic and inflammatory markers 76 , However, until long-term follow-up studies are conducted, the results must be interpreted with caution.

Our review has several strengths and limitations. Its strengths include our comprehensive search strategy, the inclusion only of randomized clinical trials, the low risk of bias among the studies selected, and restricted inclusion criteria e.

These criteria allowed us to investigate their potential benefits on lipid profiles and inflammatory biomarkers systematically.

The limitations pertain primarily to the inability to draw strong conclusions based on significant statistical and clinical results. Omega-3 polyunsaturated fatty acids may be associated with improvements in inflammatory biomarkers and lipid profiles among diabetic and cardiovascular patients.

However, the review did not identify clear benefits for these markers and profiles. Clinicians should be aware of these potential benefits before prescribing omega-3, and it is essential that patients consult with clinicians before any omega-3 intake because of the current limited data on its effects.

The expression of GRP32 was also confirmed in human bone-marrow derived neuroblastoma cells In three mouse models of depression, RvD2 was shown to have positive effects on depressive-like behavior, however, only one study also investigated cellular outcomes.

Central RvD2 administration was reported to improve FST and TST scores in LPS-induced 36 and in a CUS model of depression Similarly, in a model of fibromyalgia-associated depression, intravenous RvD2 prevented immobility in the FST With respect to cellular findings, RvD2 administration partially prevented total brain serotonin loss and increased glutamate levels To our knowledge, only one study described findings on the behavioral and cellular effects of RvD2 administration in neurodegenerative disorders.

In a LPS-induced PD model, intracranial addition of RvD2 to apomorphine, a non-selective dopamine receptor agonist, improved motor function of rats more efficiently, when compared with apomorphine alone Regarding cellular findings, RvD2 effectively reduced the number of activated microglia and increased the ramified phenotype in the substantia nigra of rats with PD.

This was also shown in a primary culture of cortical microglia from neonatal rats Among the studies previously mentioned, only one investigated the mechanisms underlying the effects of treatment with RvD2 in a model of depression.

In one study, RvD2 was reported to exert its beneficial actions through microglia in LPS-induced PD models. Specifically, RvD2 decreased transcription of several cytokines such as IL, IL-6, TNF-α, and IL-1β in the cytoplasm in an in vitro model of PD using rat primary cortical microglia.

The expression of these cytokines was also reduced in the plasma of PD rats after central injection of RvD2. Moreover, RvD2 effectively prevented an up-regulation of NF-κB p65 subunit and IκBα in ventral mesencephalon microglia of PD rats The evidence summarized in this section highlights the role of RvDs in reducing depression-like behavior in models of depression, and in decreasing glial inflammatory processes in neurogenerative models.

RvE series were shown to have beneficial effects in mice when injected centrally. Administration of RvE1, RvE2, and RvE3 improved behavioral despair in the TST in a LPS-induced model of depression 48 , This was also demonstrated in the FST, but only in respects of intracranial RvE1 and RvE2 injection One in vivo study investigated the behavioral effects of RvE1, and two in vivo studies investigated the cellular effects.

In a mouse model of TBI, peripheral RvE1 administration affected sleep during the first 12 h post-injury. Specifically, an overall increase in number, but not length, of sleep bouts in both light and dark periods was seen upon RvE1 administration On a cellular level, RvE1 administration increased the number of ramified microglia and decreased the number of rod microglia in the primary somatosensory cortex of mice In addition, intraperitoneal injection of RvE1 with LXA 4 decreased microgliosis and astrogliosis in the cortex and hippocampus of AD mice One in vivo study proposed two different mechanisms of actions for RvEs using a model of LPS-induced depression in mice.

Firstly, intracranial injection of RvE1 and RvE2 produced anti-depressant effects similar to those observed by activating ChemR23, a G-coupled receptor activated by chemerin 62 and RvE1 63 , suggesting the involvement of this receptor in depression. Secondly, inhibition of the mTORC1 pathway was able to prevent the anti-depressant effects of RvE1 In an in vivo transgenic mouse model of AD, RvE1 was shown to exert its effects through down-regulation of various pro-inflammatory factors.

Specifically, peripheral RvE1 injection reduced levels of IL-6, IL-1β, IL, granulocyte-macrophage colony-stimulating factor GM-CSF , IFN-γ, TNF-α, monocyte chemoattractant protein 1 MCP-1 , macrophage inflammatory protein MIP -1a, and MIP1b in the prefrontal cortex The evidence summarized in this section supports the potential of RvEs, similar to RvDs, to alleviate depression-like behavior, which would occur via mTORC1 activation.

In terms of neurodegenerative disorders, studies clearly present RvEs as beneficial agents against the increased levels of cytokines and pro-inflammatory factors present in those conditions. Behavioral effects of PD1 administration were measured in three in vivo studies, one in the context of epilepsy and two in the context of stroke, both conditions which are associated with increased central inflammation affecting neurogenesis-related cognitive processes.

Intracranial PD1 administration improved cognitive function, specifically non-spatial recognition memory, in the novel object recognition task in kainic acid-induced epilepsy in mice PD1 also reduced frequency and seizure duration and prevented weight loss Additionally, intravenous injection of PD1 and its aspirin-triggered isomer AT-PD1 improved neurological recovery in rat models of ischemic stroke using middle cerebral artery occlusion 51 , Cellular outcomes were investigated in nine studies both in vivo and in vitro , predominantly using models of AD and ischemia.

Intravenous administration of PD1 in vivo reduced immunoglobulin G IgG immunoreactivity in the cortex, subcortex, and whole right hemisphere of rats subject to ischemic stroke It also inhibited astrocyte and microglia activation in the penumbra of ischemic rats Likewise, intracranial infusion of PD1 in epileptic mice decreased astrogliosis and microgliosis in the hippocampus, and increased neuroblasts migration in the hilus In a mouse model of TBI, intracranial administration of PD1 also improved parenchymal cell survival In vitro , PD1 treatment decreased Aβ 42 production 56 and prevented Aβ 42 -induced apoptosis and increased cell viability in two human models of AD, both using cortical neuron-glia co-culture 32 , This was also observed upon treatment with protectin isomer, PDX, in a human bone-marrow derived neuroblastoma cell model of AD In a rat dopaminergic mesencephalon neurons model of PD, PD1 treatment decreased dendritic retraction and increased neuronal survival Finally, in an in vitro model of ischemia, PDX also increased proliferation of mice subventricular zone neural progenitors One in vivo and two in vitro studies investigated the mechanisms of PD1.

In vivo , transcription and expression of IL-1β and TNF-α were reduced in the hippocampus upon PD1 intracranial administration in a murine model of epilepsy In an in vitro model of AD, PD1 administration reduced Aβ 42 production through repression of pro-inflammatory molecules, including COX-2 and TNF-α Furthermore, PD1 enhanced expression of anti-apoptotic proteins of the B-cell lymphoma 2 Bcl-2 gene family 32 and reduced caspase-3 activity in cortical human neuronal cells in vitro Based on the evidence summarized in this section, protectins are especially useful in reducing behavioral deficits observed in neurological disorders, most likely via reducing microgliosis and pro-inflammatory cytokines levels.

One in vivo study investigated the behavioral effects of treatment with MaR1, whereas three in vitro studies assessed cellular outcomes. In an in vivo mouse model of stroke, intracranial administration of MaR1 reduced neurological impairments over time On a cellular level, administration of MaR1 protected against brain cell death and inhibited the degradation of postsynaptic density protein 95 PSD95 and synapsin.

Furthermore, MaR1 administration also inhibited neutrophil infiltration and glial activation in the cortex In vitro , MaR1 treatment prevented cell death in human bone-marrow derived neuroblastoma cell models of ALS and AD 46 , MaR1 also stimulated an increase of Aβ 42 phagocytosis in embryonic human microglial cells All three studies previously mentioned investigated the mechanisms of action of PD1.

In an in vivo mouse model of stroke, expression of TNF-α, IL-1β, and MCP-1 in the cortex was reduced by intracranial administration of MaR1. Furthermore, MaR1 decreased NF-κB activation through down-regulation of p65 phosphorylation Similar effects were seen in vitro , with MaR1 treatment decreasing levels of phosphorylated NF-κB in human bone-marrow derived neuroblastoma cells MaR1 treatment of embryonic human microglia also induced a reduction in pro-inflammatory markers including CD11b, major histocompatibility complex class II MHC-II , CD86, CD40, and CD33 The limited evidence available on maresins suggests that they might benefit neurological conditions, specifically by reducing cell death and inflammatory factors, which may be related to decreased NF-κB pathway activation.

This review summarizes evidence on the beneficial effects of resolvins, protectins and maresins, in the treatment of psychiatric, neurodegenerative, and neurological disorders Figure 2. Overall, treatment with both RvD and RvE improved depressive-like behaviors in various animal models of depression, whereas PD1 and MaR1 ameliorated neurological function.

On a cellular level, RvD1 and RvD2 increased serotonin levels in a model of depression, and decreased gliosis in neurodegenerative disorders. In contrast, PD1 and PDX prevented neurite and dendrite retraction and apoptosis in models of neurodegeneration, while MaR1 reduced cell death across all studies.

In terms of mechanisms, all SPMs down-regulated pro-inflammatory cytokines, such as IL-1β, IL-6, and TNF-α. These findings suggest that not only do SPMs have anti-inflammatory properties across different models, but also possess characteristic therapeutic effects depending on the condition.

Figure 2. Comparison of behavioral, cellular, and molecular findings upon treatment with SPMs in the context of psychiatric, neurodegenerative, and neurological disorders. Despite the scarce number of studies conducted in psychiatric disorders, differences among specific SPMs could be drawn on several levels.

In particular, RvD1 and RvEs were the most effective in improving depressive symptoms across several mouse models 36 , 39 , 48 , This could be explained by their mechanistic actions, which were notably distinct between psychiatric and neurological conditions.

The mTORC1 pathway, which is a key signaling pathway in the effectiveness of antidepressants 64 , was found to underlie the behavioral effects of resolvins 36 , Moreover, all of these are key elements involved in neurogenesis 66 , which is impaired by pro-inflammatory cytokines 67 and has been shown to be rescued by n-3 PUFAs treatment after IL-1β challenge in vitro With respect to neurodegenerative disorders, none of the SPMs could be distinguished in terms of better therapeutic effects.

While apoptosis or gliosis were equally reduced by RvD1, RvE1, PD1, and MaR1 in in vivo and in vitro models, the benefits observed in ex vivo studies using patient-derived cells remained on a trend level 41 or were restricted to specific sub-groups Although it is difficult to disentangle the underlying cause of these seemingly puzzling findings, the situation can be closely related to the reality of research into AD therapy.

Many anti-inflammatory drugs appear promising at pre-clinical stages but are not effective in clinical trials, presumably due to the complexity of the disorder and the number of interacting factors Further investigation is thus necessary to achieve a clearer understanding of SPMs in neurodegenerative disorders.

Although, maresins and protectins have not been examined in the context of depression, the evidence was conclusive in neurological disorders, where they appear to have a greater potential. PD1, PDX, and MaR1 improved neurological function in animal models of ischaemia, and TBI 51 , 53 , In line with this, PD1 limited cell death, highlighting its neuroprotective abilities.

MaR1 likely had a greater effect in these conditions due to its presence in macrophages and its more potent role in dampening the activation of microglia 69 , which are more acutely and severely triggered in those conditions.

Additionally, MaR1 promotes tissue regeneration, which could be of increased therapeutic value in ischemic stroke Thus, the ability of specific metabolites to improve behavioral, cellular and mechanistic components differentially in psychiatric and neurodegenerative disorders could be a basis for new personalized therapeutic strategies.

Although current pharmacotherapies for AD and PD appear to slow the progression of cognitive impairment, the benefits have often found to be marginal and non-sustained Additionally, up to one third of MDD patients fail to respond to first-line pharmacological treatment 71 , which has been associated with elevated plasma pro-inflammatory factors expression N-3 PUFAs have been approved as safe when administered in doses up to 3 g per day and minor side-effects are rare Recent reviews and meta-analysis have reported a clinical efficacy of n-3 PUFAs treatment, which might be partly attributable to SPMs, in MDD and AD patients 76 , More interestingly, the majority of the animal studies so far only used males, which have recently been shown to have higher baseline levels of n-3 PUFAs metabolites than females in brain tissue The single study using female mice reported positive effects of RvE1 on inflammatory factors, however, this does not allow for direct comparison between sexes With women being at increased risk of developing MDD and AD 79 , 80 , further insight into this question is necessary as they might even more particularly benefit from this type of intervention.

Based on the findings from our review, personalized SPMs treatment could be a therapeutic possibility. RvD1, RvD2, or RvE1 could prove to be beneficial in psychiatric conditions, like depression, while MaR1 or PD1 would be optimally targeted toward neurological conditions.

Although more studies are required to determine their exact influence and production in the brain, our review indicates a potential promising approach for tailored therapy with SPMs. With further research, this could lead to subsequent dietary recommendations and nutritional interventions in the treatment of psychiatric, neurodegenerative or neurological conditions, as n-3 PUFAs have been demonstrated to raise specific SPMs levels This review has few limitations that must be considered, such as the number of studies meeting the inclusion criteria and the prominence of cognitive and neurological compared with psychiatric studies.

Additionally, dosage and route of administration between metabolites was also variable. Nonetheless, this is the first review to compare the effects of SPMs in the context of psychiatric, neurodegenerative and neurological disorders and sheds light on the differential mechanisms mediating their beneficial properties.

Further research is needed to elucidate the exact mechanisms of action of these metabolites, as well as the extent of their anti-inflammatory properties, in order to discern which disorder they should optimally target.

Omega-3 fatty acids and inflammation

The concept of inflammation resolution depends primarily on the active class switch in the mediators from classical prostaglandins and leukotrienes to promising newer immunoresolvents molecules 1.

Endogenous immunoresolvent lipid mediator molecules e. Although lipoxins are derived from different sources than are others arachidonic acid vs. dietary fatty acids, primarily fish oil , together, they all can help inhibit neutrophil recruitment, promote tissue regeneration and the lymphatic removal of phagocytes, and attenuate proinflammatory gene expression 47 , 48 , 49 , 50 , 51 , Several strategies have been used to control diabetes, such as lifestyle changes and eating plans e.

Some studies have introduced omega-3 fatty acids to decrease levels of fasting plasma glucose FPG and improve lipid profiles, inflammatory mediators, and reduce insulin resistance 58 , 59 , However, low dosages of omega-3 fatty acids may have limited effects on insulin resistance, inflammatory markers, and lipid profiles among HIV patients and certain other populations These molecules can have anti-diabetic properties because of improved insulin metabolism and the anti-atherosclerotic and anti-inflammatory effects attributable to the resolution of inflammation, as mentioned previously As a consequence, the reduced proinflammatory mediators on the one hand, and the increased production of anti-inflammatory molecules, such as adiponectin, on the other will improve insulin resistance 46 , 64 , However, omega-3 intake may change the HDL cholesterol subfraction composition and absolute size.

Omega-3 fatty acids also lower triglycerides by reducing the hepatic secretion of VLDL cholesterol Further, it may decrease triglycerides and increase LDL cholesterol in patients with hypertriglyceridemia Our study has shown LDL level increases and triglyceride level reductions. However, this mechanism remains unclear and some studies have shown neutral effects Thies et al.

suggested that another way in which omega-3 fatty acids might act on CVD patients is by stabilizing advanced atherosclerotic plaques and reducing their anti-inflammatory effects thereby However, this study showed that omega-3 fatty acids improved TNF-alpha levels.

Thus, this systematic review summarized all published results of omega-3 fatty acid intake on these aspects. Several investigators have proposed this hypothesis because of their beneficial effects on morphologic and inflammatory markers 76 , However, until long-term follow-up studies are conducted, the results must be interpreted with caution.

Our review has several strengths and limitations. Its strengths include our comprehensive search strategy, the inclusion only of randomized clinical trials, the low risk of bias among the studies selected, and restricted inclusion criteria e. These criteria allowed us to investigate their potential benefits on lipid profiles and inflammatory biomarkers systematically.

The limitations pertain primarily to the inability to draw strong conclusions based on significant statistical and clinical results. Omega-3 polyunsaturated fatty acids may be associated with improvements in inflammatory biomarkers and lipid profiles among diabetic and cardiovascular patients.

However, the review did not identify clear benefits for these markers and profiles. Clinicians should be aware of these potential benefits before prescribing omega-3, and it is essential that patients consult with clinicians before any omega-3 intake because of the current limited data on its effects.

ALA is found in plants and is available in vegetable oils, nuts, flaxseeds, and flaxseed oil. Several studies have evaluated fish oil supplements for preventing heart disease, cancer, and other conditions related to inflammation, but there is still no convincing evidence to recommend them—especially at such a high dose.

The one exception is if you have very high levels of triglycerides in your blood. Then your doctor may prescribe Lovaza, a fish oil medication containing milligrams mg of ALA and mg of DHA, to be taken four times a day.

If your doctor hasn't prescribed high doses of fish oil, you'd be better advised to add foods containing omega-3s to your diet. Nonprescription fish oils are notoriously prone to spoilage. Editors in Chief, Harvard Women's Health Watch.
