Introduction
In general, people with high blood pressure can consume foods such as celery, bananas, kiwifruit, oats, and black fungus. They may also take medications such as nifedipine sustained-release tablets (Ⅱ), irbesartan tablets, hydrochlorothiazide tablets, metoprolol tartrate tablets, and perindopril tert-butylamine tablets as directed by a physician for management. Additionally, it is important to maintain a low-salt diet, limiting daily salt intake to no more than 5 grams, and to keep regular作息 (daily routines), avoiding staying up late.

Generally speaking, lowering blood pressure can include eating foods such as celery, bananas, kiwifruit, oats, and black fungus, or following medical advice to take medications such as nifedipine sustained-release tablets (II), irbesartan tablets, hydrochlorothiazide tablets, metoprolol tartrate tablets, and perindopril tert-butylamine tablets for regulation. Detailed explanations are as follows:

1. Celery

It contains apigenin and 3-n-butylphthalide. Apigenin can dilate blood vessels, and 3-n-butylphthalide can improve vascular elasticity, assisting in lowering blood pressure. Celery is also rich in dietary fiber, which can reduce fat absorption and prevent abnormal lipid levels from worsening blood pressure issues. It is suitable for stir-frying or making cold dishes.

2. Banana

Rich in potassium, which helps eliminate excess sodium ions from the body, reducing water and sodium retention, lowering blood volume, and thus assisting in alleviating elevated blood pressure. It also contains vitamin B6, which regulates the nervous system and prevents emotional fluctuations from affecting blood pressure. It is suitable for moderate daily consumption.

3. Kiwifruit

Contains vitamin C, dietary fiber, and arginine. Vitamin C protects vascular endothelial cells, dietary fiber regulates blood lipids, and arginine converts into nitric oxide in the body, which dilates blood vessels, reduces vascular pressure, and helps control blood pressure. It is suitable for direct consumption.

4. Oats

Rich in beta-glucan, a soluble dietary fiber that lowers cholesterol levels in the blood, reducing the risk of atherosclerosis and preventing elevated blood pressure caused by decreased vascular elasticity. Additionally, oats delay the rise in blood sugar, indirectly helping to stabilize blood pressure. They are suitable for making oatmeal porridge.

5. Black fungus

Contains polysaccharides and dietary fiber. Fungal polysaccharides inhibit platelet aggregation and improve vascular wall elasticity. Dietary fiber promotes the excretion of metabolic waste, reduces vascular burden, and helps regulate blood pressure. It is suitable for cold dishes or stir-frying with vegetables.

II. Medications

1. Nifedipine Sustained-Release Tablets (II)

Belonging to calcium channel blockers, they prevent calcium ions from entering vascular smooth muscle cells, causing blood vessels to dilate, reducing peripheral vascular resistance, thereby lowering blood pressure. They are suitable for patients with mild, moderate, or severe hypertension, especially effective for elderly patients with hypertension.

2. Irbesartan Tablets

An angiotensin II receptor antagonist that blocks the binding of angiotensin II to receptors, inhibiting vasoconstriction, reducing aldosterone secretion, lowering blood pressure, and simultaneously protecting the kidneys. Suitable for hypertensive patients with diabetic nephropathy.

3. Hydrochlorothiazide Tablets

A thiazide diuretic that promotes the excretion of sodium ions and water, reducing blood volume, decreasing cardiac load, thereby lowering blood pressure. Suitable for mild to moderate hypertension, often used in combination with other antihypertensive drugs to enhance effectiveness.

4. Metoprolol Tartrate Tablets

A beta-blocker that slows heart rate, reduces myocardial contractility, decreases cardiac output, and inhibits renin release, assisting in lowering blood pressure. Suitable for hypertensive patients with concomitant coronary heart disease or tachycardia.

5. Perindopril Tert-Butylamine Tablets

Belonging to angiotensin-converting enzyme inhibitors, they inhibit the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and lowering blood pressure. They can also improve ventricular remodeling and are suitable for hypertensive patients with concomitant heart failure.

In daily life, a low-salt diet should also be maintained, with daily salt intake not exceeding 5 grams; regular作息, avoiding staying up late; appropriate exercise such as jogging or tai chi to control weight; seek timely medical attention when necessary and adjust medications under medical guidance, avoiding self-discontinuation or dose reduction.
