A new study suggests that certain minerals, including potassium and zinc, may play a role in protecting against depression. Researchers from Korea and the U.S. found that higher potassium levels were consistently linked to a lower risk of depression. Zinc also appeared protective in U.S. participants, while sodium showed benefits in Korean participants.

Experts say these minerals support brain health by helping nerve signals, balancing fluids, and reducing inflammation. Potassium, in particular, is vital for heart health and neurotransmission, yet many people don’t get enough because of low fruit and vegetable intake.

Nutritionists recommend adding potassium-rich foods like spinach, lentils, bananas, and yogurt to daily meals. While diet alone isn’t a cure for depression, nutrient-rich foods may complement traditional treatments and help strengthen mental well-being over time.
