Renal Diet Food List

Kidney disease is a common issue touching about 10% of the global population. Kidneys are bean-shaped small organs that perform various crucial and powerful functions in the body.

Kidneys are responsible for balancing fluids in the body, filtering waste products, producing urine, releasing hormones that regulate blood pressure, among other crucial functions.

There are a couple of ways in which these crucial organs can be damaged. BP (blood pressure) and diabetes are the most common risks that bring about kidney disease.

In addition, age, gender, genetics, and smoking can also increase this risk.

High blood pressure and unregulated blood sugar can damage blood vessels in the kidneys reducing their capability to work optimally.

In addition, when the kidneys aren’t functioning well, waste products accumulate in the blood, including waste from food.

As a result, it’s crucial for individuals suffering from kidney disease to stick to a special diet.

Kidney Disease and Diet

For persons with advanced kidney disease, it’s vital to stick to a kidney-friendly diet that helps decrease the amount of waste in the bloodstream.

This diet is known as the renal diet, and it helps enhance kidney function while preventing further harm.

It’s widely suggested that all persons with kidney disease limit the following nutrients:

Phosphorus: Damaged kidneys can’t expel excess phosphorus, a mineral present in many foods.

High phosphorus levels can cause harm to bodies; therefore, phosphorus is limited to less than 800-1000 milligrams (mg) per day.

Potassium: Potassium plays several significant roles in the body, but those with kidney disease need to restrict potassium to avoid severely high blood levels.

It’s usually suggested to limit potassium to less than 2,000 milligrams (mg) per day.

Sodium: Sodium is found in a couple of foods, and it’s a major constituent of table salt.

Damaged kidneys can’t remove excess sodium, causing their blood levels to climb. So it’s often recommended to restrict sodium to less than 2,000 milligrams (mg) per day.

What not to take on a Renal Diet

Limit Calcium and Phosphorus

You need these minerals to maintain your bones healthy and strong. When your kidneys are okay, they eradicate the phosphorous you don’t need.

However, if you have CKD, your phosphorus levels can be a bit too high.

This puts you at increased risk of contracting heart disease. In addition, your calcium amounts start to decrease. To make up for it, your body gets it from your bones.

This can make them feeble and easier to break.

What about Fluids?

If you have early-stage CKD, you don’t need to reduce fluids. However, if your condition becomes worse, your physician will inform you if you need to cut those too.

To reduce fluids, you can:

  1. Manage your thirst with ice chips, frozen grapes, or sugar-free hard candies.
  2. Stay away from salty foods.
  3. Track your fluid intake in a journal.
