Among those who eat walnuts, depression occurs in 26% less.
American scientists analysed dietary habits and mental health more than 26 thousand people and found that eating walnuts is associated with a lower risk of depression. According to an article published in the journal Nutrients, among fans of walnut depression were found in 26% less often, and they have seen more interest in daily activities and less hopelessness, informs Rus.Media.
It is believed that a healthy diet helps you maintain not only physical but also mental health. Most useful in this regard can rightly be called the Mediterranean diet, which is characterized by a large number of fresh vegetables and fruits, whole grains, nuts and seeds, fish and chicken, as well as the limited consumption of animal meat. Last year, scientists using a meta-analysis has shown that the Mediterranean diet reduces the risk of depression by a third.
However, the effectiveness of a Mediterranean (or any other) diet could be explained by the fact that effective actually one product or group of products. In the new work, scientists from the University of California at Los Angeles under the leadership of the Arab Linor decided to check how related the consumption of walnuts and the risk of developing depression.
The researchers analyzed data about health and habits 26656 people, which were divided into several groups, depending on how often they ate walnuts and other nuts. Given the adverse variables like Smoking and alcohol consumption, researchers found that among those who consume nuts (an average of about 24 grams per day) depression was found in 26% less likely than fans of other nuts and those who do not eat nuts at all. No such effect was observed among women. Also among the fans of walnuts there was a large interest in daily activities, they feel more energetic and less hopeless.
Walnuts possess many useful properties, the main of which – the high content of α-linolenic acid, which is considered essential (taking an active part in metabolism) fatty acid of plant origin. Studies indicate a positive role of the consumption of walnuts in improving some cognitive functions and slow the aging process. However, the results of this work should be treated with caution: due to the fact that scientists have not conducted long-term studies, it is possible to conclude a causal relationship, besides data on food habits was gathered on the basis of just two days.
