The teas that diabetics can drink include black tea, green tea, pu-erh tea, etc. There are no contraindications in terms of tea. Tea contains mainly a very good substance, namely tea polyphenols, and this substance has antioxidant and anti-aging effects. In addition, tea can also lower cholesterol and triglycerides, thus reducing the risk of cardiovascular disease in diabetic patients, so it is recommended that diabetic patients can appropriately drink tea after meals. It should be noted that diabetic patients must drink a little lighter tea when drinking tea and avoid drinking strong tea. In addition, diabetic patients taking oral hypoglycemic drugs should not be served with tea, which may affect the effect of hypoglycemic drugs.
