3. Dark-Colored Sodas: A Phosphorus Trap

Dark-colored sodas, like cola, contain high levels of phosphorus, a mineral that can build up in your blood when your kidneys aren’t functioning well. Excess phosphorus can lead to bone disease, calcification of blood vessels, and heart problems.

Phosphorus in sodas is often in a form that is easily absorbed by the body, making it even more dangerous for those on dialysis. Because dialysis may not remove enough phosphorus, it’s essential to limit or avoid these drinks entirely.

Instead of dark-colored sodas, opt for water, clear sodas, or natural fruit-infused water. Keeping your phosphorus levels in check will help protect your bones and overall health.

4. High-Phosphorus Foods: A Risk to Your Bones

In addition to sodas, many foods are high in phosphorus, such as dairy products, nuts, seeds, and whole grains. While phosphorus is necessary for bone health, too much of it can lead to brittle bones and calcification of soft tissues in those on dialysis.

High phosphorus levels can cause your body to pull calcium from your bones, weakening them over time. This imbalance is particularly dangerous for dialysis patients, who already have to manage their mineral levels carefully.

To avoid these risks, limit your intake of high-phosphorus foods and consult with your dietitian to choose lower-phosphorus alternatives. Phosphate binders may also be prescribed to help control phosphorus levels in your blood.
