Patients with hypertension are recommended to eat low-sodium salt, which includes potassium, magnesium and other trace elements, especially potassium chloride with a content of about 30%, which is suitable for people with hypertension. However, it is important to note that people with severe renal insufficiency and arrhythmias should not eat low sodium salt, because it can lead to electrolyte disorders and increased potassium intake, which may promote the occurrence of arrhythmias. For people with high blood pressure, usually pay attention to other lifestyle adjustments, to a low-fat diet, and more intake of fruits and vegetables.
