For good moods, eat trees and vegetables

An apple a day can keep your body healthy. According to researchers, this tree directly affects your brain's work.

A team of psychologists from Otago University, New Zealand, has asked hundreds of young people to take notes about their food consumption.

At the end of the test period, it has been found that all who consume large quantities of trees and vegetables are happier, more relaxed, and more energy.

People who consume fast food, meanwhile, often have mood changes.

After a detailed analysis, it has been found that young people must consume between 7 and 8 systems of trees and vegetables during a single day in order to observe the marked positive change in their organism.

The study has also revealed the conclusion that food greatly affects people's moods.
