It has been speculated earlier that a healthy diet can raise the mood and reduce symptoms of mild depression. A new study proves the cause and effect of a healthy diet and improved symptoms of depression. because  The results of the new study titled, “The effects of dietary improvement on symptoms of depression and anxiety a meta-analysis of randomized controlled trials,” was published this week in the latest issue of the journal Psychosomatic Medicine.

Symptoms of depression

The study from Western Sydney University looked at 16 clinical trials that analyzed 45,826 people who had modified their diets to alleviate their symptoms of depression and anxiety; The clinical trials are from more than one nation including Australia, Brazil, Canada; Italy, and the UK. because of Lead researcher Dr. Joseph Firth from Western Sydney University said that the major change that their diets involve is reducing “junk food intake” and replacing high fat and high sugar foods with; foods that are rich in nutrients and fibers such as fruits and vegetables.
Dr. Firth said, “We took a bit of a close look at the data and interestingly found there were no significant differences in the types of diets used  Weight loss diets were just as effective as nutrient boosting diets.” This means that no “extreme diets” are necessary for depression; he explained. What is need is a change in the basics he says. Dr. Firth added that the study did not find a beneficial effect of diets on anxiety disorders and women with depression is find to benefit more with an alternate diet than men.

Individual consumes

Dr. Firth said that there have been studies showing that regular exercise can have a protective effect against depression. This is the first study to prove that a healthy diet can also play a role in reducing the symptoms of depression. because He explained that an average Australian individual consumes around 19 servings of junk food per week and much less amount of the recommended fruits; vegetables and whole grains that are rich in nutrients and fiber.
The authors emphasize that diet is not a replacement to tested and accepted treatments of depressive illness including medications and psychotherapy. However; diets can be an additional remedy they said. They call for public health campaigns to emphasize upon healthy diet and its effects on mental health.

Public health

“Public health schemes are trying to improve people’s diets and looking at physical health outcomes and focusing on combating things like obesity They should also pay attention to actual positive mental health outcomes that; could occur and improve people’s diets on a large scale to fix people’s psychological well being;” Dr. Firth said.
“Thus, depressive disorders incur considerable burden not only for individuals but also for society due to the high economic cost from lost productivity and demand on healthcare services;” The authors write. Authors add that dietary interventions could be a “novel” approach to depression and conclude; “Future research is require to determine the specific components of dietary interventions that improve mental health; explore underlying mechanisms, and establish effective schemes for delivering these interventions in clinical and public health settings.”
