The food we eat affects us in many ways. A recent study from Massachusetts General Hospital and Harvard Medical School found a link between the consumption of ultra-processed foods and an increase in the risk of depression. Ali Rogin speaks with Olivia Okereke, an associate professor of psychiatry at Harvard Medical School who worked on the study, to learn more.

    “found a link between”? Please demonstrate statistical significance via null hypothesis rejection.

    Downvotes all you want, this is standards statistics for demonstrating correlation

      Compared with those in the lowest quintile of UPF consumption, those in the highest quintile had an increased risk of depression, noted for both strict definition (HR, 1.49; 95% CI, 1.26-1.76; P < .001) and broad definition (HR, 1.34; 95% CI, 1.20-1.50; P < .001) (Table). Models were not materially altered after inclusion of potential confounders. We did not observe differential associations in subgroups defined by age, BMI, physical activity, or smoking. In a 4-year lag analysis, associations were not materially altered (strict definition: HR, 1.32; 95% CI, 1.13-1.54; P < .001), arguing against reverse causation.

      “Found a link between” typically is pop science speak for small p value. Not that I would take it for granted that it does, so you should just read the paper if you have a question about the details: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10512104/
