Omega-3s reduce allergic symptoms
Dietary ω-3 fatty acids alter the lipid mediator profile and alleviate allergic conjunctivitis without modulating T2 immune responses.
High relevance to allergy research
We discovered that a diet enriched with omega-3 fatty acids can effectively reduce symptoms of allergic conjunctivitis (AC) in mice. This reduction occurred without influencing the typical immune responses usually associated with allergies. Instead, omega-3s worked by changing the lipid molecules linked to inflammation.

Notably, these fatty acids completely suppressed itching near the eyes and significantly decreased the presence of eosinophils, cells commonly involved in allergic reactions. However, total serum IgE levels and T2 cytokine expression remained unchanged, suggesting that omega-3s tackle AC symptoms in a unique way.

Omega-3s and skin allergies
ω3 fatty acid metabolite, 12-hydroxyeicosapentaenoic acid, alleviates contact hypersensitivity by downregulation of CXCL1 and CXCL2 gene expression in keratinocytes via retinoid X receptor α.
Critical exploration of 12-HEPE
We uncovered intriguing insights into how eicosapentaenoic acid (EPA) and its metabolite, 12-hydroxyeicosapentaenoic acid (12-HEPE), play a role in managing allergic responses, particularly in the skin. Our study revealed that when mice consumed an omega-3 fatty acid-rich diet, 12-HEPE became a significant metabolite in their skin.

Interestingly, we observed that the enzymes responsible for producing 12-HEPE were more active in the skin compared to other organs. This effective metabolite appeared to reduce inflammation caused by contact hypersensitivity. Specifically, we found that applying 12-HEPE topically limited the influx of neutrophils, a type of white blood cell involved in inflammatory responses.

Taking our research a step further, we investigated the effects of 12-HEPE on human skin cells, or keratinocytes, in lab conditions. Our findings showed that 12-HEPE inhibited two specific genes that cause neutrophils to be attracted to the site of inflammation, showcasing its potential as a therapeutic agent for allergy management. Overall, we identified 12-HEPE as a potent metabolite in the skin, suggesting that dietary omega-3 fatty acids could be a beneficial strategy in controlling allergic reactions.

Maternal omega-3 reduces allergy risks
Maternal Omega-3 Supplementation During Pregnancy, but Not Childhood Supplementation, Reduces the Risk of Food Allergy Diseases in Offspring.
Findings indicate critical timing
We conducted a comprehensive meta-analysis to explore how omega-3 supplementation affects food allergy risks in children, focusing on whether maternal intake during pregnancy or childhood supplementation is more effective.

Our findings revealed that mothers who took omega-3 during pregnancy and lactation significantly lowered the chances of their infants developing allergies to eggs and peanuts.

However, omega-3 consumption later in childhood did not show similar benefits in allergy prevention. This emphasizes the critical timing of supplementation in allergy risk management.

Docosahexaenoic acid helps asthma
Lipid mediators obtained from docosahexaenoic acid by soybean lipoxygenase alleviate ovalbumin‑induced allergic asthma in mice by reducing airway inflammation and oxidative stress.
Study examines DHA's anti-asthmatic effects
We explored the potential of lipid mediators derived from docosahexaenoic acid (DHA) for alleviating allergic asthma. Using a model where mice were challenged with ovalbumin (OVA) to induce asthma-like symptoms, we administered lipid mediators that included 17S-monohydroxy DHA, resolvin D5, and protectin DX. These treatments led to significant improvements in key aspects of asthma such as reduced inflammatory cell infiltration and lower levels of Th2 cytokines.

Following treatment with the lipid mediators, we observed decreased levels of interleukin-6, tumor necrosis factor-α, and IgE—important markers associated with allergic reactions. There was a notable reduction in inflammation and oxidative stress in lung tissues, which suggests a protective effect on the lungs. Additionally, histological examinations revealed fewer signs of inflammation and mucus secretion.

The results indicate that DHA-derived lipid mediators may effectively mitigate the symptoms of allergic asthma and offer a promising new approach for treatment. They seem to act by reducing inflammation and improving antioxidant defenses within the lungs.

New hypoallergenic formula shows promise
Hypoallergenicity assessment of an extensively hydrolyzed whey-protein formula in cow's milk allergic infants.
Impact of DHA on allergies unclear
We set out to assess a new extensively hydrolyzed whey-protein formula, which includes docosahexaenoic acid (DHA), for infants with cow's milk allergy (CMA). This study involved 34 children, primarily with IgE-mediated reactions, participating in a double-blind, placebo-controlled food challenge. Remarkably, all the children tolerated the new formula during the trial. This is significant since the American Academy of Pediatrics states that successful tolerance in over 90% of CMA children is crucial for a product to be considered hypoallergenic.

Although our focus was on the overall efficacy and safety of this formula, it's important to note that while DHA was included, we stopped short of isolating its specific impact on allergy outcomes. Thus, while we noted that this new formula is well-tolerated and associated with healthy growth and gastrointestinal tolerability, we cannot definitively state the effect of DHA alone on allergies. We recognize that further research would be needed to explore DHA's specific role in allergy management.

Eicosapentaenoic acid benefits allergies
Evaluating the Effect of Eicosapentaenoic Acid in Children With Atopic Dermatitis: A Randomized Triple-Blind Clinical Trial.
Directly addresses EPA for allergies
We explored the impact of dietary eicosapentaenoic acid (EPA) in children suffering from atopic dermatitis, a common allergic skin condition. In a well-structured study, forty-eight children were divided into two groups: one received 250 mg of EPA twice daily, while the other was given a placebo for four weeks.

The study aimed to measure the effectiveness of EPA by examining improvements in the SCORing Atopic Dermatitis (SCORAD) index and the need for topical corticosteroids. What we found was quite promising—after just two weeks, the EPA group showed significant improvement in their SCORAD scores compared to the placebo group.

Additionally, by the end of four weeks, fewer children in the EPA group required corticosteroids, indicating a potential reduction in the severity of their condition. Overall, the results suggest that EPA supplementation is both effective and well-tolerated among young patients with atopic dermatitis, offering a supportive strategy for managing this allergy-related issue.

Eicosapentaenoic acid reduces inflammation
Effect of Omega-3 Polyunsaturated Fatty Acids Intake on Eosinophil Airway Inflammation in University Athletes.
Direct insight into EPA's effects
We assessed how eicosapentaenoic acid (EPA), a type of omega-3 fatty acid, influences airway inflammation related to allergies in university athletes. In our study, we had 23 male participants divided into three groups based on their levels of airway inflammation, measured by fractional exhaled nitric oxide (FeNO).

These athletes took daily supplements containing 600 mg of EPA for three weeks. During this time, we tracked changes in their FeNO levels and other respiratory factors. Our findings revealed a significant drop in FeNO levels among athletes with eosinophilic airway inflammation, indicating a reduction in airway inflammation.

Notably, while the athletes with high FeNO levels benefited from the supplementation, those without eosinophilic characteristics saw no significant changes in their respiratory status. This suggests that EPA may be particularly effective for certain allergy-related conditions, rather than universally beneficial for all types of respiratory issues.

Careful with Omega
A wonderful omega 3! We have chosen this one for now. I particularly appreciate the refined fish oil from deep-sea fish like anchovies and sardines. So far, it has caused no allergies, but not everyone can take Omega; please read contraindications and consult your doctor before use.
