The GI value of buckwheat flour is relatively low in cereals, so it is one of the staple foods that are not easy to make people fat. In addition, buckwheat flour contains rutin, which helps to prevent hypertension and arteriosclerosis, so its nutritional value is much higher than that of ordinary flour. The most common method of buckwheat noodles is cold noodles. Boil buckwheat noodles in boiling water until soft, drain the water with cold water and put them on a plate. Add shredded cucumber, shredded carrot, boiled eggs and other ingredients you like, and then pour the sauce, and a bowl of refreshing cold noodles will be ready.
