Nutritional Value of Soy Products
Among natural foods, soybeans are one of the few plant-based sources of high-quality protein, with a protein content of over 40%. Soy products are foods made from soybeans and other legumes, either through fermentation or non-fermentation processes.
On one hand, soy products are an important source of high-quality protein in the human diet. After soybeans are processed into soy products, the proteins are partially broken down into smaller structures, making them easier for the human body to absorb and utilize.
On the other hand, while soybeans themselves do not contain vitamin B12, fermented soy products do provide this essential nutrient.
In addition, the fats found in soy products are unsaturated fats, which are healthier than the saturated fats commonly found in meat. Soy products are also rich in lysine, an amino acid often lacking in cereal grains, making them a complementary food to grain-based diets.
The Chinese Nutrition Society recommends a daily intake of 30–50 grams of soybeans or an equivalent amount of soy products to ensure that high-quality protein accounts for more than 50% of the total dietary protein supply.
How to Identify High-Quality Soy Products
High-quality soy products are typically made with simple processing methods and minimal additives. Generally, healthy soy products follow the principles of "non-fried and low in additives."
Most high-quality soy products are produced through processes such as grinding, filtering, boiling, adding coagulants, pressing to remove water, or fermentation. These methods help retain key nutrients like protein, calcium, potassium, and isoflavones while keeping food additives to a minimum.
Recommended Types of High-Quality Soy Products
1. Soy Milk: Soy milk retains most of the beneficial components of soybeans. Research shows it provides a strong feeling of satiety, making it an excellent beverage for hunger control.
2. Tofu: Tofu preserves many of the nutritional benefits of soybeans, although some B vitamins may be lost during heating and processing.
3. Dried Tofu: Dried tofu, which is concentrated through pressing, contains higher levels of calcium compared to other soy products. It is also rich in protein, iron, and zinc, and has a longer shelf life.
4. Yuba: Shuangqiang Zero-Additive Yuba is made exclusively from the first layer of soy milk film. It requires about 80 jin (≈40 kg) of fresh soy milk to produce just 1 jin (≈0.5 kg) of premium yuba.
Soy Product Consumption Guidelines
- Avoid Overconsumption: Eating too many soy products at once may affect digestion and cause discomfort such as bloating or diarrhea.
- Pay Attention to Storage: Since soy products have high moisture content, they are prone to bacterial growth and spoilage if stored improperly. Fresh products such as tofu and soy milk should be refrigerated at around 4°C. If soy products develop a sour smell, or if tofu and dried tofu become slimy and lose elasticity, they are spoiled and should not be consumed.
