Foods Which Lower Blood Pressure

by Diane, M.P.H, M.S.

Plant-based diets and diets rich in whole fruits and vegetables are strongly associated with lower blood pressure, so much, that the National Institutes of Health (NIH) officially recommends adopting healthy eating practices as one of the best ways to prevent or lower high blood pressure and hypertension.’ A healthful diet can also reduce your risk of future cardiovascular problems. 

Follow a heart-healthy diet:

  • Keep a food diary: Write down what you eat, how much, when & why, even for just a week, to monitor your true eating habits.
  • Increase your dietary intake of potassium: Potassium can counter the effects of sodium on blood pressure. The best source of potassium is natural, unprocessed food such as fruits and vegetables, rather than supplements.
  • Make a shopping list before going to the supermarket to avoid buying junk food. Read food labels whenever you shop and follow a healthy-eating plan when dining out, too.
  • Eat more poultry (skinless chicken breasts, turkey), fish, nuts, and legumes (beans), tofu and less red meat.
  • Avoid frozen and breaded products, pre-marinated meats and poultry, processed chicken, bacon, sausage, deli meats which tend to be high in sodium and fat.
  • Choose low-fat or nonfat milk and other dairy products instead of full-fat versions.
  • Eat vegetables and fruits instead of sugary or salty snacks and desserts.
  • Select breads, pasta, cereals, and other carbohydrate-rich foods made from whole grains, instead of highly refined white flour.
  • Eat fruit instead of drinking fruit juice.
  • Use unsaturated fats like olive, canola, soybean, peanut, corn, or safflower oils, instead of butter, coconut oil, partially hydrogenated oil, or palm-kernel oil.
  • Choose fresh or frozen foods instead of canned and processed foods.
  • Choose low-sodium foods when possible; use herbs, spices, vinegar, and other low-sodium flavorings instead of salt.
  • Don’t skip meals; try to eat 1/3 of your calories at breakfast.

Reduce the amount of sodium you consume:

  • Estimate and record how much sodium is in what you eat and drink each day.
  • One level teaspoon of salt has 2,300 mg of sodium. Limit sodium to this amount each day or less, to help reduce your blood pressure.
  • A lower sodium level, 1,500 mg a day or less, is recommended for people 51 years of age or older, and individuals of any age who are African-American or have high blood pressure, diabetes or chronic kidney disease.
  • Read food labels: Choose low-sodium or salt-free alternatives of foods and beverages you normally buy.
  • Avoid foods high in sodium, such as canned foods, instant rice and pasta mixes, snacks like chips and crackers, foods that have been preserved or pickled, frozen entrees and fast foods.
  • Eat fewer processed foods; Potato chips, crackers, frozen dinners, bacon, processed deli meats and cheeses are all high in sodium.
  • Use herbs, spices and citrus juices, rather than salt, to add more flavor to your food.
  • If you have difficulty eliminating sodium from your diet, cut back gradually: Your palate will adjust over time.
  • Buy fresh, plain frozen, or canned no-salt-added beans and vegetables.
  • Use fresh fish, poultry and lean meat, rather than canned or processed foods.
  • Use herbs, spices, citrus juice, and salt-free seasonings in cooking and at the table.
  • Cook rice, pasta, and hot cereals without salt. Cut back on instant or flavored rice, pasta, and cereal mixes which usually have added salt.
  • Choose “convenience” foods that are lower in sodium.
  • Reduce your consumption of frozen dinners, pizza, packaged mixes, canned soups or broths, and salad dressings.
  • Rinse canned foods, such as beans, salmon or tuna, to remove some of the sodium.
  • When available, buy low- or reduced-sodium, or no-salt-added versions of foods.
  • Choose breakfast cereals without or lower in sodium.
  • The National Heart Lung Blood Institute (NHLBI) suggests eating at least 3,500 mg of potassium a day, from foods such as yogurt, cantaloupe, spinach, and bananas. Potassium may help rid the body of too much sodium by acting as a diuretic.
  • Drink plenty of water to help flush excess sodium from your body.

Avoid tobacco products and secondhand smoke:

  • Nicotine in tobacco products can raise blood pressure by 10 mm Hg or more for up to an hour after you smoke.
  • Smoking throughout the day may keep your blood pressure constantly high.
  • Inhaling smoke from others puts you at risk of various health problems, including high blood pressure and heart disease.

Reduce your intake of alcohol:

  • While alcohol in small amounts may lower blood pressure slightly, too much alcohol (more than 1 drink/day for women and men older than age 65, or more than 2/day for men age 65 and younger) will raise blood pressure.
  • If you normally avoid alcohol, don’t start drinking as a way to lower your blood pressure: There’s more potential harm than benefit to drinking alcohol.
  • Drinking more than moderate amounts of alcohol can raise blood pressure by several points, as well as, reduce the effectiveness of high blood pressure medications.
  • Keep an alcohol diary to track your true drinking patterns. One drink equals 12 ounces (355 milliliters, or mL) of beer, 5 ounces of wine (148 mL) or 1.5 ounces of 80-proof liquor (45 mL). If you’re drinking more than these amounts, cut back.
  • Reduce your intake slowly: If you are a heavy drinker, suddenly eliminating all alcohol can actually trigger severe high blood pressure for several days. Therefore, reduce your alcohol intake with the supervision of your doctor, or taper off slowly over one to two weeks.
  • Avoid binge drinking: Having 4 or more drinks in a row can cause sudden, large increases in blood pressure, in addition to other health problems.

Reduce your intake of caffeine:

  • Drinking caffeinated beverages can temporarily cause a spike in blood pressure, but whether the effect is temporary or long lasting is unclear.
  • To see if caffeine raises your blood pressure, check it within 30 minutes of drinking a cup of coffee or another caffeinated beverage you regularly drink. If your blood pressure increases by 5-10 points, reduce your intake.

Foods which can help lower your blood pressure or reduce your need for medication. Consume these as part of a comprehensive approach, including increased exercise and other lifestyle changes:

  • Fresh fruits and vegetables (5 cups a day): Rich in antioxidants, fiber, magnesium, potassium, vitamins, minerals, and other nutrients, these will help you to lower your cholesterol, lose weight, and improve your heart health. Choose these first whenever you need something to eat!
