The claim of food incompatibility is a folk rumor and has no scientific basis. If there is no allergy, duck blood and other foods, can be eaten at the same time. Duck blood is made from the coagulation of duck’s blood, which is rich in protein and a variety of trace elements and a variety of vitamins. Each 100 grams of duck blood contains 55 calories, 13.1 grams of protein, 0.3 grams of fat, and 39.6 milligrams of iron. It will not produce adverse reactions with other foods or produce harmful substances that can jeopardize your health. If there is no allergic symptoms, it is possible to take with other foods. Proper intake of duck blood is good for the body to replenish nutrients, but you should pay attention to the amount of consumption to avoid destroying the nutritional balance. At the same time, excessive consumption will increase the risk of indigestion, stimulate the body to produce bloating, nausea and other discomforts.
