Currently vinegar has some possibility of softening blood vessels, although it has not been proven in a large number of clinical trials. So patients with high blood pressure can drink vinegar, but vinegar has no clear effect on lowering blood pressure, and even if it does, the effect is very weak, and it is not recommended for patients with high blood pressure to drink vinegar as a treatment. Drinking too much vinegar can also lead to other adverse reactions, such as excessive increase of stomach acid that can easily cause gastrointestinal discomfort. In ordinary life, you can improve other bad diet to lower blood pressure, for example, the daily sodium intake should be less than 5g, eat less or no fatty meat, fried food, control the weight, quit smoking, limit drinking alcohol and so on, by insisting on regular exercise, also can assist in lowering blood pressure.
