Researchers at the University of Michigan studied whether reducing the effort of eating healthier could lower depressive symptoms. Over two weeks, participants followed a minimally processed meal plan; some received guidance and prepared meals themselves, while others received prepared minimally processed meals through a commercial delivery service. Both groups improved diet quality, and the meal-delivery group showed larger reductions in depressive symptoms.
Many participants were already in therapy, on medication, or both, yet continued to experience symptoms. Lead investigator Ashley Gearhardt said the meal delivery reduced the burden of planning, shopping and cooking, making the healthier choice easier and more convenient. The team argues that nutrition should be considered an additional tool in mental health care, not a substitute for therapy or medication.
The study links to the broader "food as medicine" movement and raises questions about food access, noting that ultraprocessed foods often dominate diets because they are inexpensive and easier to obtain. Potential groups for future programs include:
- people with severe depression
- postpartum mothers
- individuals leaving inpatient psychiatric care
The study appears in Scientific Reports. Funding came from several sources, including REDCap at UM supported by the Michigan Institute for Clinical and Health Research and federal institutes such as the National Center for Advancing Translational Sciences, the National Institute on Drug Abuse, and the National Institute of Diabetes and Digestive and Kidney Diseases.
