Veggies and Grains
Help Lower Blood Pressure
In the medical journal Circulation, researchers report a way to help lower blood
pressure, and it may be as easy as eating more vegetables and grains.
Experts say vegetable protein has a common amino acid called glutamic acid, and
this is what lowers blood pressure. The study showed that as intake of glutamic
acid went up, blood pressure went down. Participants who consumed 5 percent of their
total protein from foods that contain this acid lowered their blood pressure by
up to two points.
But veggies and grains provide other health benefits too. They may reduce risk for
stroke, diabetes, and certain cancers. So stocking up on healthy food at the grocery
store is the way to go.
Vegetable proteins can also be found in beans, whole grains, rice, soy products,
and bread. The more you eat these vegetable proteins and the less you eat animal
proteins, the more likely you are to reach and maintain a healthy blood pressure
level.
Knowing your blood pressure reading is important to your health. High blood pressure
is a major risk factor for heart disease, stroke, and other cardiovascular problems.
Blood pressure readings use two numbers, the systolic pressure (top number) and
diastolic pressure (bottom number):
- 120/80 or lower is normal blood pressure
- 140/90 or higher is high blood pressure, or hypertension
- 120 to 139 for the top number or 80 to 89 for the bottom number is prehypertension
People with prehypertension are at greater risk for hypertension.
This new study provides more evidence that an important diet called Dietary Approaches
to Stop Hypertension (DASH) helps reduce blood pressure. Designed by the National
Institutes of Health, the DASH diet is rich in fruits, vegetables, whole grains,
lean poultry, nuts, and beans.
To get started in following the DASH diet:
- Add a serving of vegetables and fruit at lunch and another at dinner.
- Use only half the butter, margarine, or salad dressing you do now.
- Choose low-fat dairy products rather than the whole-fat versions.
- Decrease your intake of soda, alcohol, or sugar-sweetened tea.
- Treat meat as only one part of the whole meal, or try meatless meals.
- Increase servings of vegetables, rice, pasta, and dry beans in meals.

Studies show that a diet high in fruits and vegetables may reduce the risk of certain
diseases, including heart disease, stroke, and some types of cancer. Fruits and
vegetables also are low in calories and fat, so they can help you maintain a healthy
weight.
Government experts recommend eating 2 cups of fruit and 2.5 cups of vegetables daily
for people who consume 2,000 calories per day. Depending upon your diet, you
may need more or fewer fruits and veggies.
But what makes a serving? For fruit, it is 1/4 cup dried fruit, 1/2 cup
cut-up fruit, 3/4 cup fruit juice, or one medium fruit.
