STUDY TITLE: Genome-wide association study of dietary intake in the UK biobank study and its associations with schizophrenia and other traits

SUMMARY: Identification of 63 genetic variants associated with a plant and fish-based diet.

OVERVIEW:  Schizophrenia is a chronic brain disorder that affects how a person thinks, feels, and behaves. It affects about 1% of the population. While the development of schizophrenia is driven by genetics, environmental factors, such as diet, are also thought to play a role as weight gain and obesity are common in schizophrenia patients. Therefore, to determine the genetic basis of diet and whether there is a link between diet and schizophrenia risk, researchers examined the genomes of over 335,000 individuals of European ancestry. The study identified 63 genetic variants associated with a diet rich in fish and vegetables. Interestingly, the researchers found that the genetic factors contributing to a diet rich in fish and vegetables were also contributing to the risk of developing schizophrenia. This unexpected result highlights that the relationship between diet and schizophrenia is very complex.

DID YOU KNOW? Unlike most other brain disorders, schizophrenia typically appears when a person is in his or her or early 20s. [SOURCE]
