Researcher explains connection between ultra-processed foods and depression

The video discusses a study linking ultra processed foods to an increased risk of depression, particularly in middle-aged white women. The study, part of the Nurses Health Study, found a 50% higher risk of depression for those consuming nine or more portions of ultra processed foods daily. Artificial sweeteners were also linked to higher depression risk. The study's limitations include its demographic focus, and future research should explore diverse populations and underlying mechanisms like inflammation and metabolic changes.
