Is Salmon Good for Your Kidneys? The Answer May Surprise You
Salmon is well known as a superfood loaded with beneficial nutrients like protein, omega-3 fatty acids, vitamins and minerals. But is salmon also good for your kidneys? As someone living with chronic kidney disease (CKD), you likely pay close attention to your diet. Knowing which foods to eat more of and which to limit is key to supporting your kidney health.
The good news is salmon checks all the right boxes. Here’s what you need to know about the health benefits of salmon, why it’s kidney-friendly, and some tasty ways to add it to your meal plan.
Why Is Salmon Considered a Superfood?
Salmon is one of the most nutritious types of fish you can eat. Here are some of its biggest health benefits:
-
High-quality protein. A 3-ounce serving of salmon contains about 17 grams of protein. Protein provides essential amino acids your body can’t make on its own. It preserves muscle and gives you lasting energy.
-
Omega-3 fatty acids. Omega-3s, which help fight inflammation, are found in large amounts in salmon. They are good for your heart and brain. Omega-3s also help manage cholesterol levels.
-
Vitamin D. Salmon is one of the few natural sources of vitamin D, which regulates calcium absorption and promotes bone health.
-
Selenium. This antioxidant mineral boosts immunity and thyroid function. It also protects cells from damage.
-
B vitamins. Salmon contains niacin, riboflavin, thiamin, B6, and B12. These vitamins help convert food into cellular energy.
-
Potassium. An electrolyte mineral, potassium helps balance fluids and maintain normal blood pressure.
-
Phosphorus. This mineral strengthens bones and generates energy in cells.
With its stellar nutritional profile, it’s easy to see why salmon deserves superfood status. Next, let’s look at why salmon is a smart choice if you have CKD.
Why Is Salmon Good for Your Kidneys?
Salmon checks all the right boxes for a kidney-friendly diet:
-
Lean protein. Salmon provides high-quality protein without excess saturated fat. This makes it ideal if you need to limit protein intake. A 3-ounce portion gives you sufficient protein in a reasonable serving size.
-
Omega-3 fatty acids. These healthy fats help reduce inflammation. Keeping inflammation in check is important for kidney health. Omega-3s also benefit your heart, which is good news since CKD raises your risk for cardiovascular disease.
-
Rich in nutrients. Salmon contains lots of vitamins and minerals that are beneficial if you have CKD, like vitamin D, selenium, B vitamins, potassium, and phosphorus.
-
Low sodium. Fresh salmon is naturally low in sodium. This helps manage blood pressure and fluid retention. Avoid canned salmon, which can be high in added salt.
-
Low mercury. Compared to larger fish like tuna, salmon tends to be low in mercury. Mercury is a heavy metal that can harm kidneys in high amounts.
On top of its nutritional benefits, studies show salmon positively impacts kidney health:
-
Reduces protein in urine. Eating fish is linked to lower levels of albuminuria, which is protein in the urine. Albuminuria signals kidney damage, so keeping it low protects kidney function.
-
Protects kidneys in diabetes. Salmon helps reduce kidney damage in those with diabetes. Since diabetes is the leading cause of CKD, this is great news if you have both conditions.
-
Manages cholesterol. Salmon raises “good” HDL cholesterol. High cholesterol is tough on the kidneys, so this effect is beneficial.
The omega-3s in salmon deliver anti-inflammatory and heart-healthy benefits. And salmon provides protein, vitamins, and minerals specifically beneficial for CKD. For all these reasons, salmon is a smart, kidney-friendly way to get your protein.
How Much Salmon Should You Eat with Kidney Disease?
Salmon offers major benefits, but as with any food, moderation is key. Here are some general guidelines on how much salmon to eat with CKD:

-
CKD stage 5 or on dialysis – Higher protein needs mean you can safely enjoy salmon two times a week. Stick to 3-ounce portions to control phosphorus intake. Always consult your care team on your diet.
-
After transplant – Avoid raw salmon to minimize food poisoning risk from bacteria. Cook salmon until it flakes easily with a fork and reaches 145°F internal temperature.
-
Pregnant or nursing – Limit salmon to one serving a week to minimize mercury exposure to baby. Choose wild salmon over farmed.
No matter your stage of CKD, keep portions in check and opt for wild salmon when possible. Now let’s explore some delicious ways to enjoy this kidney superfood.

“No Salt Added” Foods
When you don’t have kidney or cholesterol problems, you don’t know how much salt is in everything. You need to be especially cautious when it comes to any pre-packaged or canned foods. Make sure to check the sodium levels on all products. Also, avoid using salt when you cook your own meals at home.
Don’t use any kind of salt, even if it’s flavored. Pre-seasoned or flavored foods are also off the table. Sodium can cause huge flare-ups in your kidney disease that may have drastic effects in the long run.
If you can’t use salt and you’re desperate to add some flavoring to your foods, look no further than red bell peppers. They have huge amounts of Vitamin A and Vitamin C, and they are very low on potassium. According to DaVita, potassium is one of the most harmful substances for kidney disease.
For a tasty meal, mix red bell peppers with your favorite protein. They’re also great as a snack.
Are you sick and tired of being on the dialysis diet? Add garlic to your food! It tastes great and has many natural ingredients that can fight infection and harmful bacteria. Don’t use garlic salt, though—use garlic powder instead! Garlic is a strong and tasty food ingredient as long as it doesn’t have any sodium in it.
An Apple a Day
Apples are an often underestimated fruit. Although they are naturally sweet, they aren’t too sugary or unhealthy in any way. In fact, apples are known scientifically to reduce the effects of inflammatory conditions and diseases, including kidney disease. Apples can also lower cholesterol and decrease the risk of cancer. This is because apples have a lot of anti-inflammatory qualities that make it a true superfood.

There is an antioxidant in blueberries that can help reduce swelling, redness, and other signs of irritation in your kidneys.
Plus, blueberries increase brain health and brain activity, and can even strengthen bone mass. They are an excellent food to eat even when you’re not on a kidney diet!.
Egg whites serve as a reliable protein option when you’re on a renal diet. Egg whites give you all of the amino acids your body needs to promote good health. In addition, if you’re on a renal diet, you need to cut down on the phosphorous you eat. Egg whites have the least amount of phosphorous of any protein.
Another solid protein option is fish with omega-3 fatty acids. For your health, salmon is the best fish, but any fish that is low in mercury and cholesterol will do. The American Heart Association and kidney experts around the world recommend this as a healthy protein choice that has many health benefits. You should eat fish at least twice a week. Salmon, trout, tuna, and mackerel are some of the best fish to eat.
