Does Dairy-Free Milk Really Cause Depression?

A new study has raised concerns that drinking plant-based milk, including oat milk, may increase the risk of depression and anxiety. However, the study does not specifically mention oat milk and the term "other types of milk" does not solely refer to plant-based options. The study also did not investigate whether participants who consumed non-cow's milk were vegan, vegetarian, or omnivorous.

Evidence on the link between meat-avoidance and depression is mixed, with some studies showing that high-quality diets, regardless of meat consumption, can lower rates of depression. In fact, soy, commonly consumed by vegans, has been found to have protective benefits for mental health. Overall, misrepresenting study findings may discourage people from adopting a plant-based diet, which can offer numerous health benefits beyond mood improvement.

Other studies have shown conflicting results on the relationship between dairy consumption and mental health. While some found associations of dairy with conditions such as prostate cancer and heart disease, others showed no link between semi-skimmed milk and mental health. The authors of the study warning readers to interpret the findings cautiously, as further research is needed to validate the results and explore the impact of milk consumption on mental health.
