The remedy reduces symptoms in people experiencing the symptoms of depression.

Eating better reduces depression symptoms, new research finds.

Three common diets have similar positive effects, whether people are trying to lose weight, reduce fat or just improve the nutrients in their diet.

There is no need for a special depression-busting diet: simply eating more fruit and veg and avoiding junk food will help.

Dietary changes are particularly beneficial for women, the scientists found.

Dr Joseph Firth, the study’s first author, said:

“The overall evidence for the effects of diet on mood and mental well-being had up to now yet to be assessed.

But our recent meta-analysis has done just that; showing that adopting a healthier diet can boost people’s mood.

However, it has no clear effects on anxiety.”

The conclusions come from almost 46,000 people who were involved in every existing clinical trial looking at diet and mental health problems.

The results showed that all three types of diet — a nutrient boosting, weight loss and fat reduction diet — ease depression symptoms.

Dr Firth said:

“This is actually good news.

The similar effects from any type of dietary improvement suggests that highly-specific or specialised diets are unnecessary for the average individual.

Instead, just making simple changes is equally beneficial for mental health.

In particular, eating more nutrient-dense meals which are high in fibre and vegetables, while cutting back on fast-foods and refined sugars appears to be sufficient for avoiding the potentially negative psychological effects of a ‘junk food’ diet.”

Exercise will boost the positive effects of diet changes, said Dr Brendon Stubbs, study co-author:

“…when dietary interventions were combined with exercise, a greater improvement in depressive symptoms was experienced by people.”

It is not yet clear how diet improves mental health, said Dr Firth:

“It could be through reducing obesity, inflammation, or fatigue—all of which are linked to diet and impact upon mental health.

And further research is still required to examine the effects of dietary interventions in people with clinically-diagnosed psychiatric conditions.”

The study was published in the journal Psychosomatic Medicine (Firth et al., 2019).

Increased intake of this vitamin is particularly important for reducing depression risk.

A healthy diet including plenty of folates is linked to lower depression risk, research finds.

Folates include vitamin B9, folacin and folic acid.

Some of the best dietary sources of folates include:

• vegetables,
• fruits,
• liver,
• and whole-grains.

Folate levels are particularly high in chickpeas, yeast extract, lentils and broad beans.

Losing weight is also linked to a lower risk of depression.

In contrast, eating junk food, sugar and processed foods was linked to increased depression risk by the study.

People who ate more foods like sausages, sugary snacks and drinks, manufactured foods and processed potatoes had higher depression risk.

The conclusion comes from a Finnish study of over 2,000 middle-aged men.

They were tracked for up to 20 years while their diet and mental health was monitored.

In another related study, 140 men and women were assigned to one of two groups.

One group ate a healthy diet while the other continued as normal.

The results again showed that a healthy diet including higher intake of vegetables, fruits, whole-grains and fish was linked to lower depression risk.

Increased intake of folates is particularly important.

Dr Anu Ruusunen, the study’s author, said:

“The study reinforces the hypothesis that a healthy diet has potential not only in the warding off of depression, but also in its prevention.”

The studies were published by the University of Eastern Finland (Ruusunen et al., 2013).
