You want to be happy and not feel depressed, and while we don't understand all the reasons for depression, new research suggests that low-grade systemic inflammation may be involved(Wium-Andersen MK, et al. 2013).
This is exactly what the reviewed research investigated by measuring plasma levels of C-reactive protein (CRP), an inflammatory marker. 73,131 participants both men and women between the age of 20 and 100 years were included.
The conclusion of the study was that elevated levels of CRP are associated with increased risk for psychological distress and depression in the general population.
Maybe this looks a little bit strange to you, but the food you eat could actually be contributing to this type of inflammation, and for that reason also affect your mood.
