Summary
Dr. Berg addresses whether 7–10 cups of salad or vegetables can meet daily potassium requirements. He explains that vegetable type matters significantly, and that combining vegetables with other whole foods makes hitting the target achievable. Supplemental sources like electrolyte powder can further close any gaps.
Key Takeaways
- Vegetable type matters: Not all vegetables provide equal potassium — leafy lettuce contributes less than denser vegetables like broccoli, cauliflower, and asparagus.
- 7–10 cups of mixed vegetables typically provides approximately 2,000–3,000 mg of potassium, which may not fully meet total daily requirements on its own.
- Mixed nuts (1 cup) contribute 847 mg of potassium — a significant additional source.
- Animal protein (5 oz portion) adds roughly 300 mg of potassium.
- Avocado (one whole) provides 800 mg of potassium.
- Salmon (6 oz) also delivers around 800 mg of potassium.
- Wheatgrass juice powder contributes potassium but should not be relied upon as a primary source — it functions best as an enhancement on top of a whole-food diet.
- Electrolyte powder with potassium citrate can provide 1,000 mg per serving, helping bridge the gap to reach daily targets.
Details
Potassium from Vegetables
The potassium content of 7–10 cups of vegetables varies considerably depending on what is included. Dense, cruciferous vegetables like broccoli, cauliflower, and asparagus yield higher potassium levels compared to lighter leafy greens like lettuce. On average, this quantity of mixed vegetables delivers between 2,000 and 3,000 mg of potassium — a solid foundation but potentially short of total daily needs.
Complementary Whole Food Sources
Dr. Berg emphasizes that potassium intake is cumulative across all foods consumed throughout the day. Key contributors beyond vegetables include:
- Mixed nuts — 1 cup: ~847 mg
- Avocado — 1 whole: ~800 mg
- Salmon — 6 oz: ~800 mg
- Animal protein — 5 oz portion: ~300 mg
When these foods are combined with a large vegetable intake, meeting the daily potassium target becomes realistic through diet alone.
Role of Wheatgrass Juice Powder
Wheatgrass juice powder adds potassium to the diet but is not a standalone solution. Dr. Berg recommends using it as a nutritional enhancer layered on top of a vegetable-rich whole-food diet, not as a replacement for whole vegetables.
Electrolyte Supplementation
For those who want to reliably hit their potassium target, Dr. Berg points to electrolyte powder containing potassium citrate, which provides 1,000 mg per serving. This can be used strategically to supplement dietary intake and ensure daily requirements are consistently met.
