There is a correlation between too much salt and hypertension. If large amounts of salt are consumed, it will tend to cause water and sodium retention, which is more likely to trigger hypertensive disorders. If a large amount of salt is normally consumed, it will increase the sensitivity of blood vessels to catecholamines, while the dose of norepinephrine released from sympathetic nerve endings will also increase, so it will be more likely to trigger hypertensive disease. Therefore, patients with hypertension must pay attention to a low-salt and low-fat diet, and try not to eat or consume less fried foods, high-fat foods, and smoked and pickled foods. Patients with hypertension should pay attention to a light diet and consume more fresh vegetables and fruits, such as watermelon, pineapple, grapes, strawberries, mangoes, bananas, dragon fruit, celery, leeks, spinach, broccoli, etc. among vegetables.
