Is it true that neuroses can be cured with proper nutrition?

Neurosis occurs due to an insufficient amount of folic acid in the body, the presence of which is responsible for the level of serotonin in the brain (in the common people - the “hormone of happiness”). You can restore (complete) the lack of this hormone by adding the following foods to the diet: bananas, greens, cabbage, asparagus, citrus fruits, etc. With depression, there is a lack of vitamin B6, which is also necessary for the formation of the “hormone of happiness”. Vitamin B6 can be found in such foods: shrimp, fish, seeds, nuts, chicken meat, lentils, banana.
