Anyway, here is a new study that backs this up for depression and anxiety. This cross-sectional study included 5731 men and women aged 46-49 and 70-74 years.
After adjustments for confounding variables (including age, education, income, physical activity, smoking, and alcohol consumption), a healthy diet was inversely related to depression and anxiety.
The authors conclude, "in this study, those with better quality diets were less likely to be depressed, whereas a higher intake of processed and unhealthy foods was associated with increased anxiety"
She continues, "Given that the majority of mental health problems start before age 25, and the enormous burden of illness of depression and anxiety in young people, and given that nutrition is so critical to adequate development, we think these data have enormous significant implications for public health."
The same research team has applied for funding to conduct a randomized controlled trial of diet and mental health outcomes.
"So far we know exercise is a very effective treatment strategy for depression, but we have yet to determine whether dietary improvement is an effective treatment strategy," she said. However, she added, even in the absence of intervention studies, it is not too soon for physicians to raise the issue of diet with patients suffering from anxiety and depression.
