People with hypertension are allowed to drink black tea. If it is only simple hypertension, black tea has no significant effect on blood pressure. For hypertension patients, the general principle is to eat a light diet, less greasy and not too salty. If you eat more greasy, it is easy to lead to hyperlipidemia, metabolic disorders, which will accelerate atherosclerosis, thus making it easier for hypertensive patients to raise their blood pressure and more difficult to control. If you eat too salty, it is easy to have water and sodium storage, especially in middle-aged and elderly people, leading to a continued rise in blood pressure, and blood pressure will be difficult to control. However, for patients with hypertension, drinking black tea is not much of an effect. The above is for reference only, please refer to the doctor’s face-to-face guidance for specific medication and treatment.
