Nutrition and arterial hypertension
Arterial hypertension affects nearly one in three adults in Luxembourg. A targeted dietary change structured around the DASH diet can lower systolic pressure by 8 to 14 mmHg — as much as a first-line treatment.

Clinically validated DASH diet
Target: ≤ 5 g of salt / day
−8 to −14 mmHg systolic in 6 to 8 weeks
The DASH diet: the reference approach
The DASH diet (Dietary Approaches to Stop Hypertension) lowers systolic pressure by 8–14 mmHg in 6–8 weeks.
DASH levers against sodium
Target < 5g of salt/day, tracking hidden salt.
Promotes renal sodium excretion (bananas, spinach).
Essential for vascular flexibility (almonds, seeds).
Medical treatment remains priority; nutrition is a complementary aid.
The 4 dietary pillars against hypertension
DASH (Dietary Approaches to Stop Hypertension) is the most studied dietary pattern in the world for blood pressure. It rests on four concrete levers, transposable to Luxembourgish habits.
- Reduce sodium: less charcuterie, ready meals, salty cheese and industrial sauces
- Increase potassium: bananas, potatoes, spinach, legumes, cooked tomatoes
- Favour calcium and magnesium: low-fat dairy, almonds, pumpkin seeds
- Enrich with fibre: fruit, vegetables, whole grains at every meal
Alcohol, coffee and physical activity
Alcohol directly raises blood pressure above 2 drinks a day for men, 1 for women. Excess coffee (> 4 cups/day) can also weigh on the numbers.
150 to 300 minutes of moderate aerobic activity per week (brisk walking, cycling, swimming) combined with DASH clearly strengthens the blood-pressure effect.
