The "Dietary Guidelines for Chinese Residents" recommends that we eat 25 grams of soybeans daily. What are soybeans? They mainly include green beans, black beans, and yellow beans.
So, most of the time, we do not eat soybeans directly. When converted into soy products, how much should we eat?
Converted into dried tofu, shredded tofu, or tofu skin, it is about 50g, which is two pieces of dried tofu or half a sheet of tofu skin. Converted into Northern tofu (firm tofu), it is 100g, with a size approximately equivalent to three finger joints long, two finger joints wide, and two finger joints high of an adult female's index finger. Due to different water content, converted into Southern tofu (soft tofu), it is about 150g, and glucono-delta-lactone tofu is about 200g.
