Natto cannot clear blood clots. Natto is a soybean product fermented by adding Bacillus subtilis to soybeans. Natto has a certain viscosity and smells bad, but retains the nutritional value of soybeans, 100 grams of soybeans contains 10.2 grams of water, 35.0 grams of protein, 16.0 grams of fat, 4.6 grams of ash and so on. Eating some natto appropriately on a daily basis can provide a variety of nutrients to the body. Although natto contains nattokinase, which has some preventive and therapeutic effects on blood clots, the amount of nattokinase in natto is limited to fulfill its effects. Therefore, as a food, natto can not play the same effect as drugs, so natto does not have the effect of clearing blood clots. If the body is suffering from a disease, do not believe in any folk remedies, so as not to affect the recovery of the disease. Timely to the hospital, under the guidance of the doctor to do the relevant examination, and then targeted treatment, is conducive to the control of the condition.
