Because the gypsum content of gypsum tofu is less, the side effects can be ignored.
As for getting the stone, it is sheer nonsense.
Urinary calculi are related to urinary tract inflammation, while gallstones are related to poor bile excretion and high bile concentration, but not to gypsum tofu.
What do you mean by alias? Is it a chemical name? Gypsum in tofu is edible gypsum, which is different from building gypsum. In the food industry, its official name is "food additive calcium sulfate", commonly known as "edible gypsum". Only natural gypsum can be used for production, and chemical gypsum is prohibited.
Edible gypsum has been used in food for thousands of years. In China, the earliest application is tofu, which is well known. With the development of society, the safe and non-toxic food additive calcium sulfate (edible gypsum) has been widely used in the food industry.
The uses of calcium sulfate in food include: nutrition agent, yeast activator, dough property improver, curing agent, chelating agent, gelling agent, baking powder, carrier, filler, pH regulator and abrasive. In these applications, it is mainly used for baking food. As a curing agent, it is used in canned potatoes, tomatoes, carrots, green beans and peppers. Calcium sulfate is also used as an ingredient in candied fruit, ice cream and other frozen desserts. Calcium sulfate is also used in beer brewing, and this product is added in malt treatment to increase the calcium ion content in water. Calcium sulfate is used as an abrasive in detergents that come into contact with food. Calcium sulfate is also used in cosmetics and toothpaste.
