Diet and Mental Health: Does What You Eat Affect How You Feel?

The physical health advantages of a well-balanced diet are widely documented. But, does your diet have an impact on your mental health? Over the last 10 years, research on the influence of diet mental health has exploded, with accumulating data demonstrating that diet and nutrition are just as essential in psychiatry as they are in cardiology. 

According to data from the WHO World Mental Health (WMH) Surveys, more than 25% of the global population would acquire one or more mental illnesses over their lifetime. Depressive disorders are prevalent mental diseases that affect individuals of all ages and from all parts of the world. In the past, they were the second greatest cause of years lived with disability globally.

Depressive disorders, which can have a significant impact on a person's quality of life, are characterized by persistent feelings of worthlessness and somberness, as well as a lack of desire to engage in previously enjoyable activities. One of the main risk factors for mental illnesses, including depression, is psychological distress, which is defined as unpleasant feelings or sensations that impair your ability to function.

A growing body of research shows that poor-quality diets are risk factors for many mental illnesses, including depression, whereas good diets are protective. 

A recent study for psychology diagnosis compared three diet patterns at baseline and after a 10-year follow-up period, utilizing diet quality ratings to evaluate three diet patterns. The researchers discovered that eating a nutritious diet heavy in fruits, nuts, legumes, and vegetables and low in processed meats was related to a lower risk of depression. Fruits and vegetables, on the other hand, include a variety of nutrients that may be good for both physical and mental health.

Fruits and vegetables contain a diverse combination of nutrients, which may account for their health benefits. It is unknown which components may be advantageous to mental health, however, an interesting study reveals that vegetable eating may be more beneficial than fruit consumption when analyzed independently.
