Brine bean curd is made of fresh soybeans through brine, which is rich in minerals such as calcium and copper, and also contains more nutrients such as protein and carbohydrates. However, due to the high salt water used in the production process and the high salt content of brine tofu, excessive intake will increase the risk of diseases such as hypertension, heart disease and stroke, so it is not recommended to eat it for a long time. Lactone tofu is produced by fermentation, which retains more protein. Proper consumption can supplement the nutrients needed by the human body, promote metabolism and be beneficial to health. In addition, soybean isoflavones in lactone tofu can regulate endocrine and relieve menopausal symptoms, which is beneficial to women's health. Lactone tofu is also rich in beneficial bacteria, which helps to enhance intestinal health and improve human immunity. So lactone tofu is healthier than brine tofu.
