What’s in a name? Sometimes more than you’d expect. Foods that are fortified or enriched with calcium are usually easy to identify. However, other words and terms that indicate that a food is a significant source of calcium may not be so obvious.

Calcium is an essential mineral that is controlled in the diets of people on dialysis. According to the National Kidney Foundation, people with chronic kidney disease (CKD) should not exceed 2,000 mg of calcium per day. This includes not only the calcium present in food, but also that in medications and supplements such as calcium-based phosphorus binders. It’s important to work with your physician and dietitian and learn how to maintain a healthy level of calcium.

Keep an eye out for the foods listed above, consult nutrition labels and speak to your doctor or your dietitian about which foods to limit or avoid. By paying attention to items that might be hidden sources of calcium, you can maintain a healthier kidney diet.
