The inflammatory potential of the diet is associated with depressive symptoms in different subgroups of the general population
The aim of this 2017 study was to examine the relationship between the inflammatory potential of the diet and the presence of incident depressive symptoms, while also investigating the modulatory roles of sex, age, physical activity, and smoking status. Adjibade et al. recruited the 3523 participants of the SU.VI.MAX (Supplémentation en Vitamines et Minéraux Antioxydants) cohort, who were all initially free of depressive symptoms. Over an average follow-up period of 12.6 years, there were 172 reports of incident depressive symptoms. The dietary inflammatory index (DII), which measures the inflammatory potential of the diet, was not related to incident depressive symptoms among the sample population. However, DII was positively linked with risk of incident depressive symptoms in men. When the subjects were sorted by smoking status, current and former smokers with higher DII scores were also found to be more likely to show incident depressive symptoms. Finally, another meaningful relationship was identified between less physically active individuals and increased odds of depressive symptoms. To conclude, this study suggests that eating a healthy diet with anti-inflammatory properties might prevent signs of depression, especially among men, smokers, and physically inactive people.
