What is the relationship between diet and mental illness?

This article will examine the relationship between nutritional epidemiology, mental health and nutrition. Researchers are just beginning to grasp the impact of diet on mental health. This section will explain why the field of nutrition epidemiology is important, provide some tips on how to begin understanding it, and give examples of diets that are linked with improved mental health. We will delve deeper into nutritional epidemiology, and how it affects mental health.

Nutritional Epidemiology and Mental Health

It is the science of nutrition that examines how diet affects health. Traditionally, it has focused on conditions of physical health such as diabetes and heart disease. Recent research has shown that diet can also have a significant impact on our mental health.

Numerous studies have shown a correlation between mental health and diet. A 2014 review in the American Journal of Public Health concluded that poor diets were risk factors for depression and anxiety. In contrast, diets high in vegetables, fruits, whole grains, and lean proteins are linked to a reduced risk of these conditions. Understanding nutritional epidemiology will help to design diets that improve mental health.

Getting Started: Understanding Diet and Mental Health

It's important to understand what a healthy eating plan is before you can make the connection between your diet and mental well-being. World Health Organization (WHO) recommends eating a healthy diet that is rich in vegetables, fruits, beans, whole grains, and nuts. It is important to limit sugars, fats and salts.

Moreover, some nutrients are directly related to brain health. B-vitamins and antioxidants such as omega-3 fatty acids and B-vitamins are essential to mental health and optimal brain functioning. Adequate intake of nutrients like these can help support mental well-being.

Other Tips

Remember that diet is only one part of your mental health. It has been proven that physical activity can reduce the symptoms of anxiety and depression. In addition, managing stress and ensuring enough sleep through yoga or mindfulness activities can also support mental health.


Nutritional epidemiology offers valuable insight into the relationship between diet and mental health. Understanding the relationship between diet and mental health will help us make better dietary decisions. It's important to keep in mind that diet alone is not enough. A comprehensive mental health approach, including exercise, stress management, and sleep is necessary.
