Why is tofu said to be a health food?

Tofu, made from soybeans, is rich in vegetable protein, calcium, potassium and Vitamin B.
It is considered healthy because it does not contain as much fat as meat or milk, and its calorie content is very low for the amount of protein it provides.
Tofu was first made in China and introduced to Japan in the Nara period.
When eaten uncooked, since it is light in taste, it is often topped with spices such as finely chopped green onions and grated ginger, and soy sauce.
It is said that there are several hundred recipes using tofu.
