Poor diet & mental health in teens (2011)
Research has investigated poor diet & mental health in teens. Three quarters of lifetime psychiatric disorders emerge in the teenage years or in early adulthood. In an Australian study involving 2054 teenagers, researchers found that during a 2 year period, the teenagers who improved the quality of their diets experienced improved mental health. In contrast, those whose diet quality deteriorated experienced a worsening of their mental health. A better quality diet was one that included fruit and vegetables as “core food groups” and included both 2 or more servings of fruit per day and 4 or more servings of vegetables, as well as general avoidance of processed foods including chips, fried foods, chocolate, sweets, and ice cream. A poorer quality diet was defined as one which was high in snack and processed foods. This study could have important implications for prevention of mental health disorders.
