NEW YORK (Reuters Health) - Consuming fast food, especially for adolescents, frequently increases their risk of depression, experts say, adding that experts found high levels of sodium and low potassium levels among a group of middle school students surveyed.

Experts also found a link between fast food consumption and the risk of depression, as high sodium levels in the urine showed more signs of depression.

These foods include junk food, frozen, and unhealthy snacks. The study also noted that low potassium is an indicator of a diet that lacks vegetables and fruits rich in this ingredient, such as bananas, sweet potatoes, avocados and tomatoes.

A previous study indicated that following the so-called Mediterranean diet can help fight depression, where experts noted that the impact of this diet is very positive on the mood, it consists of fruits and vegetables, cereals, nuts, olive oil and fish.
