Which pasta is best for kidneys? We’ll answer all of that and more in this article! 

Why Is Potassium Important For Kidney Disease?

The main role of the kidneys are to filter out waste products. However, with kidney disease, poor filtration can lead to high levels of potassium in the body.

As kidney function declines, your healthcare team may suggest that you follow a potassium restriction. If so, ask your doctor or dietitian how much potassium you should eat in a day. 

Potassium can also be too low. Therefore, it is important to get the right amount of potassium (and not aim for zero!).  

What is considered high and low potassium?

A high potassium food will have more than 200 milligrams (mg) per serving.

However, it is considered to be a low potassium food if it has less than 200 mg of potassium.

Tips for Adding Pasta Into a Renal Diabetic Diet

  • Add in a veggie to every pasta dish to add more fiber. Zucchini, carrots, squash and peas all go well (get our full list of low potassium fruits and veggies here!). Or, add a side salad or side of steamed veggies. 
  • Choose smaller portion sizes of pasta and be sure to add in a source of fiber and fat. 
  • Take a walk after your meal. Just a ten-minute walk around the block can be a great way to bring blood sugars back down after a meal.

Tips For Adding in Pasta To Your Kidney-Friendly Diet

Choose higher fiber options. 

Fiber is essential for good heart health, digestive health and better blood sugar management. Therefore, it is very kidney friendly! An item is a good source of fiber if it has 3g of fiber or more per serving. 

Whole wheat pasta and shirataki pasta are low potassium options that have at least 3 g of fiber per 100 g. 

Take a look at how a low potassium pasta dish can fit into a high fiber day:

Low Potassium Adding in Pasta

Be mindful of protein. 

Manufacturers will add protein to certain pastas (usually in the form of pea protein or chickpea and lentil flour). 

For example, Barilla came out with a “Protein Plus” type of pasta that has pea protein as well as chickpea and lentil flour added to it.

This adds quite a bit of protein (10g in a 2oz serving of Protein Plus Angel Hair) and may not be the best option for kidney patients.  

Stick to your portion size. 

With pasta, it can be pretty easy to eat more than the suggested portion size.

Be sure to measure out the appropriate serving of pasta. In general, a pasta serving is about ⅓ cup. 

Make it a balanced meal 

Make your pasta dish more balanced by adding in lean sources of protein (like garbanzo beans or pine nuts), a fat source and produce.

For example, use olive oil to saute onions, spinach, and garbanzo beans to add to your plain pasta or pasta sauce.
