LOS ANGELES (Dispatches)-- A study has revealed that California adults who consumed more unhealthy food were also more likely to report symptoms of either moderate or severe psychological distress than their peers who consume a healthier diet.
 Jim E. Banta, PhD, MPH, associate professor at Loma Linda University School of Public Health and lead author of the study, said the results are similar to previous studies conducted in other countries that have found a link between mental illness and unhealthy diet choices. Increased sugar consumption has been found to be associated with bipolar disorder, for example, and consumption of foods that have been fried or contain high amounts of sugar and processed grains have been linked with depression.  
Banta cautioned that the link found between poor diet and mental illness is not a causal relationship. Still, he said the findings from California build upon previous studies and could affect future research and the approaches that healthcare providers administer for behavioral medicine treatments.
