Non-pharmacological interventions, particularly dietary modifications, play a major role in the management of hypertension and can potentially reduce blood pressure (BP) by at least 10 mmHg in about one in four people with high BP.

Adopt a Healthy Dietary Pattern:

  • The DASH (Dietary Approaches to Stop Hypertension) eating plan is highly recommended. Following a diet rich in whole grains, fruits, vegetables, and low-fat dairy products, and low in saturated fat and cholesterol, can lower BP by up to 14 mmHg. The DASH plan encourages eating vegetables, fruits, whole grains, fat-free or low-fat dairy products, fish, poultry, beans, nuts, and vegetable oils. Limit foods high in saturated fat (such as fatty meats, full-fat dairy, and tropical oils like coconut or palm kernel oil). The risk of coronary heart disease (CHD) and hypertension is inversely related to dietary fiber consumption.
  • The Mediterranean diet is another rigorous dietary pattern characterized by lots of fruits, vegetables, grains, nuts, and seeds, with olive oil as the main source of fat.

Reduce Sodium/Salt Intake: 

  • High salt diets contribute to high BP. Reduce dietary salt intake to no more than 5 grams per day (which is equivalent to 2 grams of sodium).This reduction can approximate an SBP lowering of 2–8 mmHg.Most dietary sodium (>70%) comes from processed foods. Avoid manufactured or processed foods with added salt, including pickles, chutneys, sauces, papads, chips, salted biscuits, canned foods, and ready-made soup powders.

Increase Potassium Consumption:

  • Potassium antagonizes the biological effects of sodium, and potassium-rich diets have been found to lower the BP of mild to moderate hypertensives. Increasing potassium supplementation (around 3.51 g per day) has been shown in trials to reduce SBP by 3.49 mmHg and DBP by 3.02 mmHg, with a greater effect noted in those with higher salt intake. 
  • Potassium-rich foods beneficial for hypertension patients include bananas, sweet potatoes, spinach, avocados, beans, and low-fat dairy products. Dietary Advice for Hypertension Patients

Manage Weight and Alcohol: 

  • Weight reduction is crucial, as greater weight gain increases the risk of high BP. Achieving weight loss can lead to an approximate SBP reduction of 5–20 mmHg per 10 kg lost. Encourage maintaining an ideal Body Mass Index (BMI) of 18.5–23 kg/m^2. 
  • Moderate alcohol intake, as high consumption is associated with increased risk of high BP. If alcohol is consumed, recommended limits are < 21 units per week for men and < 14 units per week for women, which may result in a 2–4 mmHg SBP reduction. Reducing consumption of sugar-sweetened beverages (SSBs) should also be considered, as increased SSB intake is linked to higher BP.
