FAQs
How can I make sure I’m getting enough nutrients on a low-potassium diet?
Focus on a variety of low-potassium foods like white rice, lean proteins, and allowed fruits/vegetables. Take a multivitamin if recommended by your doctor to fill any nutrient gaps.
Can I eat frozen or canned low-potassium foods?
Yes, but check labels for added potassium or salt. Rinse canned foods (like vegetables) thoroughly to remove excess sodium or potassium before eating.
Read food labels carefully, avoid salt substitutes (often contain potassium chloride), and be cautious with processed foods, sauces, and packaged snacks that may have added potassium.
