Avocados

Last Updated: January 02, 2023

Medically reviewed by NKF Patient Education Team

Avocados are nutrient-dense with 20 vitamins and minerals, low in carbs, high in healthy fats, and good for heart health. They are high in potassium and safe for kidney diets.

There are many types of avocados, the most common is the Hass avocado.  Their tough leathery skin changes color as they ripen, turning from green to almost black in color when ready to eat. The squeeze test is another way to tell when it is ripe; hold the fruit in your palm and there should be some give when you squeeze the avocado between your fingers.

Why are avocados a superfood?

  • Avocados are very nutrient-dense. They contain about 20 different vitamins and minerals. 
  • They are unique in their nutrient profile as they are lower in carbohydrates and higher in fat compared to other fruits. 
  • Avocados are rich in monounsaturated fat. This type of fat can help reduce your LDL (“bad”) cholesterol and inflammation.
  • They are a good source of fiber which is great for gut health, keeping you full, and aiding in blood sugar control.
  • One serving (1/3 of an avocado) contains about 250 mg of potassium.

Avocados and kidney disease

Avocados, like most fruits, are not a significant source of phosphorus or sodium. They are considered high-potassium food. Working with a kidney dietitian can help you with your potassium needs based on your stage of kidney disease and labs. Find a kidney dietitian.

Chronic kidney disease (CKD) and transplant

Those who have early-stage kidney disease or kidney transplant often do not need to restrict potassium. If your blood tests show high potassium levels, ask your kidney dietitian how to safely include avocado in your eating plan.

Hemodialysis (3 times a week)

Most people on hemodialysis can include higher potassium foods like avocados when they are mindful of portions and other sources of potassium in their diet. Work with your kidney dietitian to figure out how to safely include avocado in your eating plan.

Daily home dialysis, nocturnal hemodialysis, and peritoneal dialysis

Some people doing these types of treatments need more dietary potassium since more potassium is removed from the blood. Work with your kidney dietitian to help figure out how much avocado you can safely consume.

Kidney stones

Eating avocados will not have an effect on forming kidney stones.

How to cut open and store an avocado

Use a chef’s knife to cut into the length of the avocado until the knife hits the pit. Keep the knife in place and rotate the avocado around the knife to slice it in half. With your hands, twist the avocado halves apart. To remove the pit, hit the pit with the sharp blade of your knife. The avocado flesh can be scooped out of the skin with a spoon.

To store an avocado once it’s cut keep the pit in and cover it with plastic wrap by pressing the wrap directly onto it. Then place it in a container with a lid to help with discoloration.
