Can CKD patients consume soy protein?

It is found that many patients have been particularly concerned about their diet since they were diagnosed with chronic kidney disease. Which ones can be eaten? What can't be eaten? You have to ask to be clear, and even want the doctor to make a recipe to eat.

It is true that for patients with kidney disease, daily diet is very important. A reasonable diet can not only supplement the nutrients the body needs, but also protect the kidneys and delay the progression of kidney disease. Unreasonable diet may increase the burden on the kidneys and promote the progression of the disease. For patients with chronic kidney disease, doctors usually recommend moderate intake of high-quality protein (a high-quality low-protein diet).

 

Someone will definitely ask what is high-quality protein? Generally speaking, high-quality protein is animal protein, such as fish, chicken, eggs, dairy products, etc., and its bioavailability is high (it can not only supplement the human body's nutritional needs, but also does not produce a lot of metabolic waste). As a plant protein, soy protein contains more non-essential amino acids and has low bioavailability. It is considered that it will increase the metabolic burden of the kidneys. Therefore, many doctors have not recommended that patients with kidney disease take soy protein.

 

However, in recent years, a large number of animal experiments and clinical experiments at home and abroad have shown that soy protein diet can protect kidney function and delay the progression of the disease. Many clinicians classify soy protein as a high-quality protein and recommend that patients consume it in moderation.

So soy protein was not recommended for patients with kidney disease in the past, so why does it have the effect of protecting kidney function? The following we will take everyone to learn about the latest research.

 

Soy protein component Soy refers to soybeans, green beans and black beans. Soy protein occupies the main part of soybeans and is a high-quality protein. Among all plant proteins, soy protein is the only complete protein similar to animal protein. Soy protein is rich in amino acids, including 9 essential amino acids needed by the human body, with a bioavailability of 65% to 96%, and a digestion and absorption rate of 84% to 98%. Animal experiments and clinical experiments show that soy protein can slow down the decline in glomerular filtration rate (GFR), and can effectively reduce urine protein in patients with kidney disease, and has a certain protective effect on kidney function. Soy protein can lower blood pressure and improve dyslipidemia caused by kidney disease.

Using soy protein isolate to make tofu

图片
Soy protein isolate is a plant-based protein extracted from soybeans that has high purity, high nutritional value, and no cholesterol. ‌ It is a protein powder obtained from low-temperature desolubilized soybean meal as raw material and processed through a series of processes. Its protein content is more than 90%, it is rich in amino acid types, and contains essential amino acids for the human body. Soy protein isolate is not only nutritionally comparable to animal protein, but because it does not contain cholesterol, it is one of the few plant proteins that can replace animal protein. ‌ Soy protein isolate has a wide range of applications and can be used as a food additive to make baby food, sports drinks, instant products, etc. It also has various health benefits such as boosting immunity, promoting wound healing, lowering cholesterol, preventing osteoporosis, etc. In addition, soy protein isolate also has a unique role in food processing. For example, injectable soy protein isolate ...

Proteins also have pros and cons.

Protein is the main participant in life activities and plays an important role in the human body. Normal adults should consume a certain amount of protein every day to maintain a positive nitrogen balance in the body. Special groups should pay more attention to protein intake to maintain health. In fact, protein also has pros and cons. There are some small details that are worth noting when choosing protein-rich foods. Today, let ’ s talk about them . ■ Soy protein The protein content of soybeans is between 36% and 40%, and the protein content of soybeans per 100 grams is about 35.0 grams. Its amino acid composition is also relatively reasonable, and its utilization rate in the body is high. It is a very good source of protein among plant proteins. Dried tofu, tofu brain, and soy milk are all good choices for sources of soy protein. Now the Isolated Soy Protein(90% protein) and Soy Protein Concentrate(65% protein) are also the better options. ■Egg protein Eggs contain 11%-14% protein a...

A good helper for regulating blood lipids - soybeans

图片
Soy milk, tofu, dried tofu, tofu skin...a soybean can be eaten in a variety of ways. It ’ s also a “ bean ” , why are soybeans so favored by people?   Bad living and eating habits have caused many people to have high blood lipids. If you want to improve blood lipids, adjusting your diet is the basis, and soybeans contain seven experts that protect blood vessels and regulate blood lipids. 1. Soy protein. Replacing some animal protein with soy protein can help reduce LDL cholesterol ("bad" cholesterol), thereby reducing the risk of atherosclerosis and cardiovascular disease. 2. Soy isoflavones. Soy isoflavones have certain antioxidant effects, which are helpful in scavenging free radicals in the human body, preventing lipid peroxidation, and preventing cardiovascular diseases. 3. Soy lecithin. Soy lecithin helps improve fat absorption and utilization, prevent cholesterol deposition in blood vessels, reduce blood viscosity, promote blood circulation, and prevent cardiovascular d...
