　　Is tofu mixed with green onions a good dish?

　　“There is a well-known old saying that tofu mixed with shallots is pure and white. Tofu mixed with shallots is also a home-cooked dish, which is both delicious and simple. In fact, this way of eating is unscientific.

　　The reason is that tofu contains calcium, while shallots contain a certain amount of oxalic acid. If the two are eaten together, they will combine to form calcium oxalate, which is not easily absorbed by the body. Especially if minced shallots are added to tofu soup, the color will turn milky white. In fact, it is the reason for calcium oxalate. Calcium oxalate will cause difficulty in the body's absorption of calcium.
