Summary
- Low potassium intake is strongly linked to higher rates of depression and anxiety, making this mineral a key factor in protecting your mental health
- Large-scale studies from Korea, the U.S., and China all show that people who consume more potassium experience greater emotional stability and fewer mood disorders
- Most Americans eat nearly twice as much sodium as potassium, reversing the ratio your body needs and driving risks like memory decline, osteoporosis, and mood struggles
- Whole foods such as spinach, broccoli, beet greens, tomatoes, cantaloupe, and grass fed yogurt are some of the most effective ways to naturally boost your potassium levels
- Choosing natural salts over processed table salt and gradually replacing packaged foods with fresh produce helps restore balance, supporting steadier energy and improved resilience to stress

| 0:24.0 | I'm Ethan Foster. |
| 0:26.1 | Today we're looking at how potassium intake tracks with depression and anxiety, why many |
| 0:31.2 | people fall short, and what simple food choices can restore a healthier balance for |

| 0:55.0 | Across national surveys in South Korea and the United States involving more than 22,000 Korean adults and nearly 10,000 American adults, |
| 1:05.0 | researchers examine seven minerals. |
| 1:08.0 | Sodium, potassium, phosphorus, magnesium, iron, zinc, and calcium, and compared |
| 1:15.5 | intake with depression risk. Adults with depression tended to consume fewer minerals overall, |
| 1:20.6 | and potassium repeatedly stood out as the mineral most closely linked to a lower likelihood of depression. |
| 1:26.1 | The overlap matters. |
| 1:28.3 | In Korea, sodium, potassium, and phosphorus were associated with less depression, |
| 1:33.9 | while in the U.S., potassium, zinc, and iron showed protective associations. |
| 1:40.7 | Potassium was the one mineral tied to better mood in both nations, |
| 1:47.0 | which points you toward a practical takeaway. Raising potassium-rich foods can support emotional stability. |
