(CNN) – A new study says processed foods could contribute to teen depression.
Researchers at the University of Alabama at Birmingham analyzed 84 middle schoolers from low-income communities in Birmingham.
Tests found high levels of sodium and low levels of potassium.
They also saw symptoms of depression with the children and their parents.
Researchers tested the group again a year and half later and noticed more signs of depression.
High sodium indicates a diet of processed foods and unhealthy snacks.
Low potassium can come from a lack of healthy fruits and vegetables.
