Don't drink tea while drinking milk or other dairy products. Because theophylline and tannic acid in tea will combine with calcium in dairy products to form water-insoluble calcium salts, the nutritional value of dairy products will be greatly reduced. Drinking a small amount of tea before or during meals is not a big problem, but if you drink a lot of tea or drink too much tea, it will affect the absorption of many macro elements (such as calcium) and trace elements (such as iron and zinc).

Green tea can regulate the impaired blood sugar of diabetic patients. Drinking three cups of green tea a day can keep the blood sugar level stable and reduce the risk of type 2 diabetes by 40%. However, drink green tea without milk. Milk will reduce the ability of green tea to stimulate insulin production.
