One landmark study showed that Australian Aborigines who returned to their hunter-gatherer diet for just seven weeks experienced significant improvements in their metabolic health.

The Hawaiian study showed measurable improvements in all of these markers in just three weeks.\u003c\/p\u003e\n\n\u003cp\u003eFor patients struggling with depression or anxiety, the findings suggest that diet quality may play an important role in mental health. The Australian women's study found that better diet quality was associated with lower rates of depression and anxiety disorders, even after accounting for socioeconomic status, education, and health behaviors. While diet should never replace professional mental health treatment, improving dietary patterns may be a valuable complement to therapy and medication.\u003c\/p\u003e\n\n\u003cp\u003eHowever, a transition to a more traditional, plant-based diet is problematic for many people due to higher costs, limited access to unprocessed foods, or food insecurity. In addition, problems such as the Arctic Dilemma—where traditional foods are increasingly contaminated with environmental pollutants—compound the difficulty of sourcing healthy, whole foods. These barriers need to be acknowledged and addressed at both individual and policy levels.\u003c\/p\u003e\n\n\u003ch2 id=\"limitations\"\u003eLimitations: What the Research Cannot Prove\u003c\/h2\u003e\n\n\u003cp\u003eIt is important to understand what these studies can and cannot tell us.

Avoid processed foods made from refined grains, sugars, and vegetable oils. Choose foods with few or no ingredients.

Returning to a traditional whole-food diet can lower triglycerides, blood pressure, glucose, and cholesterol within weeks, as seen in studies of Australian Aborigines and Hawaiians. However, these findings are observational and small, so a second opinion can help review whether dietary changes are a safe complement to therapy and how to overcome practical barriers like food access and contamination.
