Depression risk and rates are lowered on a plant based wholefood diet

Eating more fresh fruits and vegetables protects mental health; while eating junk food invites depression

“The study reinforces that a healthy diet has potential not only in the warding off of depression, but also in its prevention”
Ms Anu Ruusunen, MSc, in her doctoral thesis in the field of nutritional epidemiology, May 2014.

The population-based Kuopio Ischaemic Heart Disease Risk Factor (KIHD) Study, out of the University of Eastern Finland, examined the eating habits of more than 2,000 middle-aged or older men for up to two decades.

Foods that made the list of “protecting against depression” included fruits, vegetables, wholegrains and fish. 

Interestingly a protective link was shown in foods high in folate – such as leafy green vegetables, which actually get their name – ‘foliage’, from ‘folate’.

Junk foods such as processed meats (hamburgers, sausage rolls, hot dogs, pizza etc), and manufactured foods, were shown to be more likely linked to depression.
