Is fermented bean curd healthy food? if so, how much should i eat daily?

Fermented bean curd: Fermented bean curd is a processed form of tofu, sort of like cheese. People use it as a flavoring rather than specifically to improve health. Nattokinase, an enzyme made from fermented soybeans (natto), is another story entirely. Nattokinase decreases hyperviscosity in blood and inflammation in arteries by reinforcing plasmin -- anti stroke and heart attack. http://tinyurl.com/m2jwgtk.

Bean curd: Yes, it is very healthy - it is a form of tofu -- and as a source of protein and healthy oil, it is outstanding; if this product is new to you, start with about 1 oz per day - gradually increase to 2 oz, then 3 oz, then 4 oz per day -
