Can I eat donkey-hide gelatin if I have kidney problems? How to supplement protein for kidney disease?

There are many types of kidney disease, some of which may have complications. Kidney disease requires ensuring the intake of high-quality protein, which is usually sufficient from daily diet. So what are the sources of supplements?

Can I eat donkey-hide gelatin if I have kidney problems?

It is usually recommended that patients with chronic kidney disease eat a low-protein diet and ensure a certain amount of high-quality protein intake, but the collagen contained in donkey-hide gelatin is not a high-quality protein. From this point of view, donkey-hide gelatin is not suitable for patients with chronic kidney disease. Therefore, it is not recommended for patients with chronic kidney disease to eat donkey-hide gelatin.

If it is renal anemia, only drugs can be used to increase erythropoiesis, which can be used to treat renal anemia.

If it is iron deficiency anemia, iron supplementation is enough. On the one hand, eat iron-rich foods, but if necessary, pay attention to protein intake to supplement iron. On the other hand, we should also pay attention to the supplement of vitamin C and eat more fresh vegetables and fruits, which can promote iron absorption.

How to supplement protein for kidney disease

1. Egg protein

Eat one egg a day and combine it with other high-quality protein foods. It should be noted that egg yolks are high in phosphorus and fat. People with hyperphosphatemia and hyperlipidemia should consume them in moderation.

2. Milk protein

Every 100g of milk contains about 3g of protein, and a 250ml bag of milk contains about 7.5g of protein. One to two bags of milk a day can ensure adequate nutrition. Yogurt is formed by fermenting milk, and contains 3.98g of protein per 100g.

Both can be drunk together, but there are some dairy products called "flavored drinks" in supermarkets, which contain a lot of sugar, additives, etc. Kidney patients should pay attention to the ingredients when purchasing. It is best to choose low-fat or skimmed milk or yogurt, and drink less high-sugar products.

3. Soy protein

Although soy protein is a plant protein, its amino acid composition is similar to that of milk and eggs, and it is easy to absorb and digest. After research in recent years, soy protein has finally been vindicated as a high-quality protein.

Soybeans include yellow beans, black beans and green beans. Red beans, mung beans and other beans do not belong to soybeans. Soybeans contain 40% soy protein. The protein content of 100g of tofu we often eat is 6.2g. Kidney patients can eat it with meat, eggs and milk to supplement nutrition reasonably.

4. Meat Protein

It is recommended to eat lean red meat, and avoid eating skin and other fat-rich white meat. In addition, eat less offal of any type of animal, as it is not only high in fat and cholesterol, but also high in purine, which is not suitable for kidney patients.

Can eating donkey-hide gelatin replenish blood?

Donkey-hide gelatin is mainly composed of skin collagen, which can be hydrolyzed to obtain gelatin, protein, various amino acids, various trace elements, etc.

Among the trace elements, the main one related to blood tonic is iron. The iron content of donkey-hide gelatin is 10 mg/100 g, while the iron content of duck blood is 39.6 mg/100 g, and the iron content of pig liver is 22.6 mg/100 g. That is to say, the iron content of donkey-hide gelatin is not as good as that of animal blood and liver! Therefore, it is unreliable to rely solely on donkey-hide gelatin to nourish blood.
