Hypertension is probably the most prevalent and most undertreated modifiable cardiovascular risk factor in the world: approximately one third of the adult population has it, and only a modest proportion have adequately controlled levels; each 10 mmHg reduction in systolic pressure is associated with a 20% reduction in major cardiovascular events and a 13% reduction in all-cause mortality; the combination of nutritional and lifestyle interventions can reduce blood pressure by magnitudes comparable to individual antihypertensive drugs, especially in mild hypertension and prehypertension.
Correct measurement is critical: at rest, seated, after a 5-minute wait, with an appropriate cuff, averaging several measurements. Home self-monitoring is usually more informative than a single reading in the office (white coat effect).
Reducing dietary sodium: from 9-12 g/day (average Western intake) to 5-6 g/day lowers blood pressure by 4-5 mmHg in people with hypertension and by 1-2 mmHg in people with normal blood pressure. Most of the sodium in the modern diet comes from processed and ultra-processed foods, not from the household salt shaker.
Increasing dietary potassium: 3.5-4.7 g/day from fruits, vegetables, and legumes lowers blood pressure by 3-5 mmHg. The Na/K balance is probably more important than either one alone. Caution: people with kidney failure or who take drugs that raise potassium should not increase potassium without supervision.
Weight loss: each kilogram lost lowers systolic pressure by approximately 1 mmHg.
DASH diet (Dietary Approaches to Stop Hypertension): rich in fruits, vegetables, nonfat dairy, whole grains, nuts, legumes, and fish; low in saturated fat, red meat, and added sugars. Lowers blood pressure by 8-14 mmHg.
Mediterranean diet: effects similar to DASH, with better long-term adherence.
Regular aerobic exercise (150 min/week moderate or 75 min/week vigorous): lowers systolic pressure by 5-8 mmHg.
Strength training (2-3 sessions/week): modest reduction.
Reducing alcohol: maximum 1-2 units/day for men, 1 for women. Ideal: less.
Smoking cessation: although the acute effect is modest, the overall cardiovascular effect is enormous.
Chronic stress management: mindfulness, contact with nature, social ties.
Sufficient, good-quality sleep: treat sleep apnea if present.
Dietary nitrates (beetroot juice): 4-10 mmHg reduction in systolic pressure with regular consumption.
Coenzyme Q10: modest support in essential hypertension.
Magnesium: in people with a deficiency, supplementation lowers blood pressure modestly.
Hibiscus tea: moderate support.
Hawthorn (Crataegus): with European regulatory support for mild hypertension.
Aged garlic: modest reduction of 5-8 mmHg in mild hypertension.
Omega-3 EPA/DHA (3+ g/day): modest reduction.
Cocoa and cocoa polyphenols: modest reduction of 3-5 mmHg.
In grade 2 or higher hypertension, and in grade 1 with high cardiovascular risk, drugs are usually necessary. The main classes: - ACE inhibitors (enalapril, ramipril, perindopril): first line, especially with diabetes or kidney disease. - ARBs (losartan, valsartan, irbesartan, telmisartan): alternative with better tolerability. - Calcium channel blockers (amlodipine, lercanidipine): first line in older adults. - Thiazide diuretics (hydrochlorothiazide, indapamide): first line in older adults. - Beta-blockers (bisoprolol, carvedilol): especially with ischemic heart disease or heart failure.
Combining two drugs at low doses is usually more effective and better tolerated than one drug at a high dose.
Hypertension is highly controllable with combined interventions: DASH or Mediterranean diet, sodium reduction, increased potassium, weight loss, regular exercise, alcohol reduction, stress management, adequate sleep; complemented with specific supplements when they provide additional benefit (nitrates, magnesium if there is a deficiency, CoQ10 in some cases); when these measures are not enough, modern antihypertensive drugs are effective and well tolerated, and their use is not a sign of personal failure but of appropriate management.
