Experts suggest that the correct position of health food in diabetes treatment should be auxiliary treatment, and diabetic patients should not listen to the overstatement of advertising propaganda, such as nucleic acid health food, is not suitable for “gout patients, people with high blood uric acid, kidney function abnormalities”. When choosing health products and health food, pay attention to the manufacturer, batch number, especially the shelf life, do not choose no manufacturer, no batch number, no shelf life or expiration date of the food, so as not to damage health. To sum up, medicine can prolong life, but also can break life. Drugs used well, you can get rid of the disease, and make people quickly restore health; used badly, not only will not help the disease, but also may add new diseases, and in serious cases, even take lives. Therefore, patients must use drugs under the guidance of a doctor or pharmacist to carry out reasonably, to have to follow the law of medication, in order to ensure the use of drugs safe and effective, and make the body recover early.
