Soy Protein and Animal Protein

In today's society, people are increasingly concerned about healthy diets, and protein, as an essential nutrient for the human body, has received extensive attention regarding its sources and intake methods. When it comes to protein, many people first think of animal-based foods such as meat, fish, and eggs. However, soy protein from plant-based foods also has significant nutritional value and, in some aspects, even surpasses animal protein, making them comparable.

The Nutritional Value of Soy Protein

01 Complete Amino Acid Composition

Soy protein is a high-quality plant protein with an amino acid composition that closely matches human needs. It contains all nine essential amino acids that the human body cannot synthesize on its own, such as lysine, tryptophan, and leucine. The amino acid ratio in soy protein is relatively balanced, effectively meeting the body's requirements for various amino acids and facilitating physiological processes such as muscle synthesis and cell repair.

02 High Content of High-Quality Protein

Sybeans have a very high protein content, typically ranging from 36% to 56%, which is much higher than that of most plant-based foods. Additionally, the digestibility and absorption rate of soy protein are relatively high, approximately 90%, meaning that the human body can make full use of the protein in soybeans with minimal waste. In contrast, although animal protein has a high digestibility and absorption rate, animal-based foods often contain more fat and cholesterol. Long-term and excessive intake may have adverse effects on cardiovascular health.

03 Rich in Trace Elements and Vitamins

In addition to protein itself, soybeans are also rich in various trace elements and vitamins beneficial to the human body. For instance, soybeans contain abundant iron, zinc, selenium, and other trace elements, which play crucial roles in the immune system, antioxidation, and cell division. Moreover, soybeans contain vitamin E and vitamin K. Vitamin E has antioxidant properties, protecting cell membranes from damage by free radicals, while vitamin K is essential for bone health and blood coagulation. These nutrients, in combination with soy protein, provide comprehensive support for human health.

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 ...

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.

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...

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...
