The nutritional value of soy protein

Soy protein is a plant protein. The amino acid composition of soy protein is similar to that of milk protein. Except for methionine, which is slightly lower, the content of other essential amino acids is relatively rich. It is a plant-based complete protein. In terms of nutritional value, it can be equivalent to animal protein. It is also the closest to human body in terms of genetic structure. Amino acids, so it is the most nutritious plant protein.

Nutritional value

The food that the modern population needs should not only cause appetite, but also have no adverse side effects, and be rich in nutrients. Among the existing food groups, there is no other crop that meets the above-mentioned conditions and has abundant sources of raw materials than soybeans.

Drinks made with soy protein are hailed as "green milk" by nutritionists. Soy protein has a significant lowering effect on people with high cholesterol.

The content of arginine in soy protein drinks is higher than that in milk, and the ratio of arginine to lysine is also reasonable; the lipid and linoleic acid are extremely rich and contain no cholesterol, which can prevent cardiovascular diseases in adulthood. .

Rich in lecithin, it can remove excess sterols from the blood, and is known as the "vascular scavenger". Soy protein drinks are easier to digest and absorb than milk.

Milk is easy to form large and hard lumps after entering the stomach, while soy milk is formed into small flakes after entering the stomach, and it is soft and not hard, which makes it easier to digest and absorb.

This soy protein is an essential nutrient for everyone, but the daily dietary intake is largely insufficient, and it must be supplemented by eating protein powder, especially for certain special groups such as children, pregnant women, lactating mothers, and the elderly.


Application of soy protein in noodle products~

The lipoxygenase contained in soy flour can interact with the carotene in wheat flour, so that the color of carotene gradually fades, thereby whitening the noodle products. At the same time, the lipoxygenase acts on the hydroperoxide produced by fat. It can also oxidize -SH of wheat gluten into -SS-, strengthen the three-dimensional structure of gluten, and enhance the gluten strength of gluten products.

Soy protein has functional properties such as water retention, gelation, and oil absorption, which can make gluten more delicate and elastic, and improve the processing characteristics and sensory properties of noodle products.

Therefore, adding an appropriate amount of soy protein to the noodle product not only improves the nutritional value of the noodle product, but also improves its quality to a certain extent.

Plant-based nutrition from the perspective of functional medicine

图片
In recent years, plant-based diets have been increasingly recognized not only as a nutritional option but also as a functional therapy, showing great potential in disease treatment. Research shows that a plant-based diet not only helps improve health but may also play an important role in preventing disease. Plant-based nutrition from the perspective of functional medicine At its core, functional medicine is a patient-centered approach that seeks to explore the underlying causes of disease and reveal why certain diseases recur in specific patients. Functional medicine recognizes the important role food plays in treating or exacerbating different diseases and promotes the consumption of a plant-based diet rich in fiber, antioxidants, vitamins, and minerals. Essential elements of a plant-based diet: Phytochemicals: Rich in antioxidants and anti-inflammatory substances, which have positive effects on health. Fiber: Helps regulate blood sugar levels and promotes digestive health. Vitamins

Plant-based diets contribute to your pet's health

  A new study examined the health of 2,536 dogs fed conventional and raw meat, as well as plant-based diets for at least a year. The study recorded and studied seven disease indicators as well as 22 specific health disorders. The results showed that dogs fed a plant-based diet had better health than those fed conventional meat on all seven measures, a difference described as "significant and statistically significant." Dogs fed a plant-based diet were also more than 50 percent less likely to develop six specific health disorders—weight problems, musculoskeletal problems, gastrointestinal problems, swollen anal glands, and dental or oral problems. Not a single common health disorder was found in dogs fed a plant-based diet. Additionally, dogs in the plant-based diet group were 21% less likely to visit the veterinarian multiple times a year, 33% less likely to be considered unwell, and 33% less likely to take medications compared to dogs on a traditional meat-based diet. also s
