More foods that lower blood pressure

5. Whole-grain oats

In a 12-week study comparing whole-grain oat-based cereals to refined wheat-based cereals, researchers reported that 73 percent of hypertensive participants in the oats group were able to cut out their antihypertensive medications, or reduce them by half. The remaining participants also experienced significantly reduced blood pressure.
How they work: The fiber and magnesium found in oats both have beneficial effects on blood pressure. In addition, oats slow atherosclerosis, the plaque buildup that occurs in blood vessels.
How much: Aim for one serving (about three-fourths of a cup) of whole-grain oats per day, or at least six servings per week. For a boost of blood-pressure-lowering calcium and potassium, eat whole-grain oatmeal topped with skim milk (or unsweetened soy milk) and banana, or sprinkle oat bran on cereal and salads. Loose oats also make an excellent thickener for soups and stews.

6. Black beans

Legumes boast a high fiber-to-protein ratio that you won't find in any other type of food. This combination works wonders for regulating blood sugar and lowering blood cholesterol levels, both of which are related to maintaining normal blood pressure.
How they work: Black beans are a nutrient-dense source of fiber and magnesium, which are essential for healthy blood pressure levels. What puts them at a distinct advantage over other foods, though, is the folate you'll find in these legumes. Folate, also known as folic acid in its synthetic form, is a B-complex vitamin that appears to lower blood pressure (especially systolic blood pressure) by relaxing blood vessels and improving blood flow.
How much: 400 micrograms of folate is the recommended daily allowance (RDA). Aim for that as a minimum; 800 micrograms daily has shown significant benefit in reducing blood pressure in multiple large-scale studies. One cup of cooked black beans provides 256 micrograms of folate. Many cereals are also fortified with folic acid.

7. Berries

Calorie for calorie, berries are among the most nutritional foods on the planet when it comes to fiber and antioxidant capacity. All berries are great for you, but blueberries, strawberries, and raspberries are tops for their ability to help lower blood pressure, thanks to high doses of fiber, vitamin C, potassium, and other plant compounds.
How they work: All three berries are high in fiber, but raspberries rank highest: Just one cup delivers more than 33 percent of the daily value, for a mere 60 calories. A cup of strawberries offers 136 percent of the daily value for vitamin C. And blueberries contain a compound called pterostilbene that helps prevent plaque buildup in the arteries. Last but hardly least, berries are anti-inflammatory.
How much: Eat at least one serving (one cup) of berries per day, fresh or frozen.

8. Low-fat dairy

In a Dutch study of hypertension in adults 55 and older, researchers found that low-fat dairy products such as milk, cheese, and yogurt may help prevent hypertension.
How it works: The modest amount of fat in low-fat dairy is important because it increases the bioavailability of calcium, making it easier for the body to absorb. In addition, milk and dairy products offer blood-pressure-lowering magnesium and potassium.
How much: In a 2006 study from Harvard Medical School, researchers found that people who ate more than three servings per day of low-fat dairy showed a systolic blood pressure reading of 2.6 points less than those who ate less than half a serving per day. So aim to include skim milk, cheese, and yogurt into your three daily meals, or in between.
