EPA supplementation reduces anxietyFish oil supplementation alleviates metabolic and anxiodepressive effects of diet-induced obesity and associated changes in brain lipid composition in mice.
We explored how eicosapentaenoic acid (EPA), found in fish oil, impacts anxiety and mood disorders related to obesity. In our study, male mice were fed a high-fat diet for 20 weeks, which led to weight gain and anxiety-like behaviors.
To see if EPA could help, we administered fish oil enriched with equal amounts of EPA and DHA for the last five weeks of the study. The results were quite promising. Mice that received the fish oil not only showed reduced anxiety behaviors but also demonstrated improved metabolic health.
Specifically, these mice had better glucose tolerance and reduced food intake, indicating that fish oil could potentially correct some of the metabolic issues that come with obesity. Overall, the addition of EPA-rich fish oil appears to lessen both anxiety and metabolic disturbances caused by a saturated high-fat diet, suggesting its potential benefits for mood and health in similar conditions.

Dietary omega-3s combat stressPreventing adolescent stress-induced cognitive and microbiome changes by diet.
We explored how a diet rich in specific nutrients, including eicosapentaenoic acid (an omega-3 fatty acid), can impact cognitive function and anxiety levels in adolescents. Using a mild stress model, we focused on the effects of social instability stress on young rats, which led to noticeable cognitive and behavioral changes.
Our findings revealed that when these stressed rats were given a prolonged diet enriched with eicosapentaenoic acid, docosahexaenoic acid, and vitamin A, their performance in memory tests improved significantly. In fact, their anxiety levels and cognitive function returned to levels comparable to those of non-stressed rats.
We also observed that the enriched diet helped normalize brain chemistry and the balance of gut microbiota, both of which were disrupted by stress. Importantly, these positive changes persisted into adulthood, indicating that proper nutrition during stressful periods could have long-lasting benefits.
By highlighting the protective effects of eicosapentaenoic acid within a nutritious diet, we suggest exciting possibilities for using diet to help manage stress and anxiety during key developmental years.

Omega-3 improves anxiety in miceImpact of Omega-3 on Endocannabinoid System Expression and Function, Enhancing Cognition and Behavior in Male Mice.
We explored the impact of an omega-3-rich diet on male mice and found exciting results. Mice that consumed omega-3 showed enhancements in the endocannabinoid system, vital for synaptic function. These dietary changes led to better object recognition and reduced anxiety-like behaviors, as indicated by their time in open arms of an elevated maze.
Though the study demonstrated notable improvements in behavior and cognition, it primarily focused on mice, leaving further research needed to understand omega-3âs effects on human anxiety.

Omega-3s improve mental health outcomesPlasma Polyunsaturated Fatty Acid Levels and Mental Health in Middle-Aged and Elderly Adults.
We explored the impact of polyunsaturated fatty acids (PUFAs), particularly omega-3s, on anxiety and depression in over 102,000 participants from the UK Biobank.
The study revealed that higher levels of omega-3 PUFAs were linked to lower risks of developing anxiety and depressive disorders, alongside improvement in adverse psychological symptoms.
Additionally, the research highlighted significant associations between these fatty acids and brain white matter structure, providing valuable insights into how omega-3s might support mental wellness.

EPA alleviates anxiety in miceOmega-3 alleviates behavioral and molecular changes in a mouse model of stress-induced juvenile depression.
We examined how eicosapentaenoic acid (EPA), a key component of omega-3 fatty acids, influences anxiety levels in a juvenile mouse model affected by stress. Using an ultrasound (US) stress method, we subjected one-month-old C57/BL6 mice to varying sound frequencies that can mimic depressive-like symptoms.
Alongside the stress exposure, these mice received either an omega-3 food supplement containing EPA and docosahexaenoic acid (DHA) or a placebo. The results were striking: mice treated with the omega-3 supplement showed no signs of anxiety or depression, while those given the placebo exhibited increased anxiety, lowered motivation for reward, and elevated stress hormones in their blood.
Additionally, our metabolomic analysis revealed beneficial changes, particularly in brain energy metabolism, thanks to the omega-3 treatment. These findings suggest that eicosapentaenoic acid may help alleviate anxiety in stressful situations, implying its potential role as a therapeutic option for tackling anxiety and depression, especially in young populations.
