Answer:
False
Step-by-step explanation:
While nervous disorders, neurosis, and psychosis are primarily related to issues with the brain and mental health, diet can still play a role in their development and management.
For example, certain nutrient deficiencies can impact brain function and increase the risk of mental health problems. In addition, some foods and substances can trigger or worsen symptoms of mental health conditions, such as caffeine exacerbating anxiety or alcohol worsening depression.
Therefore, a healthy diet and proper nutrition can be an important part of an overall treatment plan for mental health disorders.
