Imbalances in the dietary intake of long-chain (LC) n-3 and n-6 polyunsaturated fatty acids (PUFAs) could potentially affect emotional regulation and lead to mental disorders, including depression. In their earlier works, Yoshikawa et al. (2015) demonstrated an association between fish consumption, a major source of LC n-3PUFA, and resilience to depression in Japanese company workers. Yoshikawa et al. define resilience as “the ability to cope with stress in the face of adversity.” The traditional Japanese dietary pattern of high fish consumption was shown to be associated with low depressive symptoms; however, the current Japanese dietary patterns have become more westernized. A major difference is seen with westernized diets entailing excessive consumption of linoleic acid (an LC n-6 PUFA) found in vegetable oils commonly used in fried food and processed foods, which is associated with the risk of depression. Thus, in this updated work (2016), the authors aimed to examine the association between the frequency of fried food consumption and resilience to depression in a population of 715 Japanese company workers. The Center for Epidemiologic Studies Depression scale (CES-D) was used to measure depressive symptoms, and a 14-item Resilience Scale (RS-14) was used to measure resilience. A self-report questionnaire based on the Food Frequency Questionnaire (FFQ) was used to measure the frequency of fish and fried food consumption. The results demonstrate significant associations between the frequency of fried food consumption and total depression and resilience scores, and between depression and resilience scores. In conclusion, an increased frequency of fried food consumption was found to be associated with lower resilience to depression. Yoshikawa et al. recommend conducting further nutritional interventional studies to increase resilience and prevent depression.
