A new study has revealed that low omega-3 fatty acid intake is significantly associated with increased ADHD symptoms among Palestinian adolescents, particularly those in resource-limited and conflict-affected settings.
The study highlights the role of socioeconomic disparities in nutritional deficiencies and suggests that dietary interventions could be a low-cost public health strategy to mitigate ADHD symptoms.

The cross-sectional study, published in the International Journal of Adolescent Medicine and Health, included 211 participants (aged 10-12 years) in Palestine, 38 of whom had an ADHD diagnosis.
The main results indicated Adolescents with ADHD had significantly lower dietary omega-3 intake compared to their peers without the disorder
.
Lower omega-3 intake was linked to more severe ADHD symptoms, with a particularly strong association found with the hyperactive/impulsive subtype.
Each unit increase in omega-3 intake was associated with a 45% reduction in hyperactive/impulsive symptoms.

The study also revealed that lower omega-3 fatty acid intake is significantly associated with higher ADHD symptom scores in Palestinian adolescents, reflecting findings from other research conducted in Western countries.
Factors such as family income, parental education, and employment were significantly associated with the children’s omega-3 intake, suggesting that socioeconomic disparities exacerbate nutritional deficiencies.
These findings align with decades of research suggesting a strong link between omega-3 fatty acid deficiency and ADHD symptoms in children and adolescents globally. Omega-3 polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are crucial for brain development and function.
Numerous studies and meta-analyses have shown Lower Blood Levels: Youth with ADHD consistently show lower blood levels of omega-3s compared to control groups.
Symptom Improvement with Supplementation:
While results can be variable across studies, many clinical trials have reported that omega-3 supplementation can improve various ADHD symptoms, including attention, hyperactivity, and impulsivity, particularly with EPA dosages of 500 mg or greater daily.
Adjunctive Therapy Omega-3 supplements are often considered a safe and well-tolerated adjunctive therapy alongside traditional medications, potentially allowing for lower doses of stimulants and improved compliance
. The study authors suggest that public health interventions focused on improving nutrition could be a cost-effective strategy to support mental and cognitive health in resource-limited and conflict-affected regions.
ADHD likely affects more than 5% of children and early adolescents worldwide. Over several decades, neurologists have identified a strong link between ADHD symptoms and deficits in omega-3, which is essential for brain growth and overall cognitive functioning.
As omega-3 can’t be produced by the body, it must be obtained through a diet rich in foods such as fish, nuts and seeds.
Most previous studies into the association between ADHD and omega-3 intake have focused on Western populations, with limited evidence from developing regions. They have also largely focused on younger children rather than early adolescents, whose dietary habits and behavioral patterns are still rapidly forming.
This new research, published in De Gruyter Brill’s International Journal of Adolescent Medicine and Health, aims to address this gap.
Professor Omar Almahmoud and colleagues at Birzeit University, Ramallah, Palestine, conducted a survey of 211 early adolescents in Palestine, including 38 with ADHD. Participants’ omega-3 intake was assessed using a culturally-adapted Food Frequency Questionnaire, reflecting dietary patterns typical of Palestinian families.
The researchers also gathered data on socioeconomic factors, including participants’ age, gender, parental education and employment, and family income. This approach enabled them to explore the association within a culturally distinct and nutritionally under-researched population.
Even when these factors were taken into account, the survey’s results broadly reflected the findings of previous studies.
“Lower omega-3 fatty acid intake was significantly associated with higher ADHD symptom scores,” Almahmoud said.
“Adolescents with insufficient omega-3 consumption exhibited more attention-related and behavioural difficulties compared to their peers with adequate intake.”
The study also identified a key link between ADHD symptoms and socioeconomic disparities, which directly affected participants’ omega-3 intake.
“These results highlight the importance of balanced nutrition – particularly omega-3 fatty acids – in supporting cognitive and behavioural health during early adolescence,” Almahmoud said.
For those looking to increase their intake of these beneficial fats, information on foods high in omega-3 fatty acids is widely available, and individuals can consult healthcare providers or use reliable resources for guidance on dietary choices.
