Excellent — diet plays a big role in controlling high potassium (hyperkalemia). I’ll give you practical, doctor-style advice that you can use or share with patients.
🥗 General Rules
✔ Aim for low-potassium foods
✔ Limit or avoid high-potassium foods
✔ Control portion size (even healthy foods can raise K⁺ if eaten a lot)
✔ Avoid salt substitutes (many contain potassium chloride)

Fruits
• Apple, pear
• Grapes, berries
• Pineapple, mango

🥔 Special Tip: Leaching Potassium from Vegetables
For potatoes, carrots, pumpkin:
1️⃣ Peel and cut into small pieces
2️⃣ Soak in water for 2–4 hours
3️⃣ Boil in fresh water
4️⃣ Throw away the water
➡️ This removes a lot of potassium
