Blood waste is the presence of various metabolic products of the body in the blood, including urea nitrogen, creatinine, carbon dioxide, urea and excessive concentrations of blood lipids, including cholesterol, triglycerides, lipoproteins and so on. How to clean up the garbage in the blood: First of all, pay attention to drink more water, because after drinking more water, more urine will be formed, and most of the garbage in the blood can be excreted with the urine. The kidneys are the main excretory organ of the human body and the main way to eliminate blood toxins. If the kidneys have problems, many metabolic wastes in the body cannot be eliminated in time and are prone to uremia. Secondly, try to avoid eating high-fat, high-calorie foods, which can effectively reduce the concentration of blood lipids, and eat more black fungus and coarse fiber foods, which can effectively promote the peristalsis of the gastrointestinal tract, which can discharge the waste in the intestines through the feces.
