In order to be able to eat a protein-rich diet, you should have an idea of where protein can be found in your diet. This article gives you an overview of protein rich foods. 
Here's what you need to know

Esto es lo que debe saber
  • Animal products such as meat, fish, sausages and cheese are especially rich in protein and therefore important for people with renal insufficiency

  • Some plant products such as legumes or cereal products can also contain protein

  • The balance between being a simultaneously protein-rich and phosphate-poor diet is a challenge for some people on dialysis

You can control your protein level primarily through your diet. Basically, you can say that all animal foods (e.g. fish, meat, sausage) or animal products (cheese, eggs) contain a relatively high amount of high-quality protein. Vegetable foods such as cereals, bread, pasta or rice also contain protein. Fruits and vegetables, as well as fats and sugar on the other hand, contain little or no protein. As a vegetarian, you should therefore pay particular attention to a sufficient protein intake.

A practical indicator for people on dialysis is the phosphorus-protein quotient. This tells you how many milligrams of phosphorus per gram of protein something contains. So the lower this guideline value, despite a lot of protein, the better it is for you as a dialysis patient.

Fruit & vegetables

As described at the beginning, there is relatively little protein in fruits & vegetables. Additionally, the little protein in it cannot be processed as well as animal protein by your body.

Legumes like lentils, peas, chickpeas and beans contain relatively high amounts of protein compared to other plant foods. Be careful of the amount though, as these can contain a lot of potassium, as well as phosphate. Similarly, tofu made from soy can be a good source of protein. Again, watch the amount because of the phosphate. Mushrooms, by the way, contain little protein.

Fish, meat & sausages

Meat and fish products are very rich in protein. Pork leads the list with 28 g protein per 100 g. But other varieties are also rich in protein, as are a wide variety of fish.

Milk & dairy products

Animal products are also generally rich in protein. Eggs and cheese are especially good for this. In the Mizu app, you will also find tips on the best types of cheese for dialysis patients based on a favorable phosphorus-protein ratio.

Potatoes, breads & cereals

There is protein in bread, pasta, rice and even potatoes. Spelt, amaranth and quinoa, for example, are particularly rich in protein. On the other hand, rice contains relatively little protein.


Peanuts, almonds, cashews, walnuts and hazelnuts are particularly rich in protein. However, they also contain a lot of phosphate and potassium. Therefore, you should not consume them in large quantities.


Sugar & fats contain little protein in principle, but you will find exceptions. Cheesecake, for example, contains relatively high protein, but can also be rich in phosphate, depending on how it is made. Always check the package information.

What else?

Be careful with sports food, such as protein powders and shakes for bodybuilders. Before you take these, you should discuss them with your nephrologist. Many of these contain additives that are dangerous for kidney patients.

Did you know…?

…that insects are particularly high in protein? While pork contains "only" 28 grams per 100 grams, crickets contain up to 70 grams per 100 grams, more than three times as much. At the same time, they contain about the same amount of phosphate as meat. Who knows, maybe cricket burgers will become the protein of the future…

So what should I do in everyday life?

As you can see, it's not that easy to eat enough protein on dialysis, while balancing phosphate levels. A good rule of thumb is to choose unprocessed products because they contain less phosphate. In the Mizu app, the phosphate-protein-quotient in the food search function also helps you find foods that are beneficial for you. It marks foods and recipes with a particularly favorable (= low phosphate + high protein) ratio.

You have to remember: It's not so important in your overall diet that you avoid a number of foods. It is much more relevant that you find a diet together with your nephrologist or nutritionist that manages to keep your important values in a target corridor. The best start to get there is to eat consciously and look up unknown foods in the Mizu app.
