Consuming onions consistently may help shield individuals against depression.
This study determined the nexus between dietary ingestion of onions and an individual's propensity to suffer from depression. Researchers utilized a combination of validated food frequency questionnaires and self-rating depression scale to assess the onion intake levels and prevalence of depression among over 250,000 men and women.
Researchers identified a downward trend in depression incidence with increase in the frequency of consumption of onions. Evidence from this study showed that habitual eating of onions may help ward off depression.
