Can the Mediterranean Diet Facilitate Prevent Adult Asthma?
Greater adherence to the Mediterranean diet may significantly reduce the risk of developing asthma in adulthood, according to a recent Spanish cohort study. The research, tracking over 17,000 adults, suggests a dietary pattern rich in fruits, vegetables, and healthy fats could play a role in asthma prevention.
The SUN Project: A Long-Term Study
Researchers analyzed data from 17,127 adults participating in the SUN Project (Seguimiento Universidad de Navarra), a long-running prospective study of university graduates in Spain. The study aimed to determine if following a Mediterranean dietary pattern was associated with the incidence of adult-onset asthma. Participants, initially free from airway disease, were followed for an average of 12.8 years.
What is the Mediterranean Diet?
The Mediterranean diet is characterized by a high intake of fruits, vegetables, legumes, whole grains, nuts, olive oil, and fish, with low consumption of red and processed meats. It’s known for its anti-inflammatory and cardiometabolic benefits .
Study Findings: A Significant Link
During the follow-up period, 302 participants (1.76%) received a new diagnosis of asthma, defined as a self-reported physician diagnosis within the previous two years. The study revealed a significant inverse association between adherence to the Mediterranean diet and asthma risk. Individuals with the highest adherence (Mediterranean Diet Score ≥7) had a 42% lower risk of developing asthma compared to those with the lowest adherence (Mediterranean Diet Score ≤2) (hazard ratio 0.58; 95% CI 0.36–0.95; p-trend=0.02).
How Was Adherence Measured?
Dietary habits were assessed using a validated food frequency questionnaire at the beginning of the study and again after 10 years. Adherence to the Mediterranean diet was measured using the Mediterranean Diet Score (MDS), ranging from 0 to 9. Participants were categorized based on their level of adherence.
Implications for Asthma Prevention
This study is the first prospective research in an adult Mediterranean population to demonstrate a significant protective association between strong adherence to the Mediterranean diet and a reduced incidence of adult-onset asthma . The findings support the idea that dietary patterns are modifiable risk factors in chronic respiratory disease and suggest that promoting Mediterranean-style eating habits could be a valuable component of asthma prevention strategies.
Further Research Needed
While promising, more research is needed to confirm these findings and understand the specific mechanisms by which the Mediterranean diet may protect against asthma. The SUN project continues to investigate the relationship between diet and various health outcomes, including cognitive function.
Key Takeaways
- Higher adherence to the Mediterranean diet is associated with a lower risk of developing adult-onset asthma.
- The study involved over 17,000 participants in a long-term prospective study.
- The Mediterranean diet is rich in fruits, vegetables, healthy fats, and whole grains.
- These findings suggest dietary interventions could be a potential strategy for asthma prevention.
