- Limit the intake of salt at the table as well as while cooking.
- Avoid highly processed foods.
- Avoid ready-to-made and canned foods high in sodium
- Prefer other seasoning food items such as lemon, herbs, and garlic instead of salt.
Fats: 2-3 servings
Examples of one serving include one tablespoon mayonnaise, one teaspoon soft margarine, or two tablespoons salad dressing.
Fat is important to absorb vital nutrients and boost your body’s immune system. But too much fat increases the risk of complications of high blood pressure, such as heart diseases and stroke.
Consumption of Total fat should not be more than 27% of your daily calorie requirement. Intake varies for different types of fats and is as follows:
- Saturated fats increase the risk of cardiovascular diseases. DASH aids in maintaining the consumption of saturated fats to less than 6% of the daily calorie requirement. Foods rich in saturated fats are butter, cheese, cream, meat, lard, coconut oil, and palm oil.
- Avoid foods rich in trans fats, such as baked goods, crackers, and fried items.
- Prefer taking monounsaturated fats, such as canola and olive oil.

Vegetables: 4-5 Servings
Examples of one serving include 1/2 cup diced cooked or raw vegetables or 1 cup of raw green leafy vegetables.

Grains: 6-8 Servings
Examples of one serving include one ounce of dry cereal, one slice whole-wheat bread, and 1/2 cup cooked rice, cereals, or pasta.

(One drink equals, five ounces of wine, 12 ounces of beer, or 1.5 ounces of 80-proof liquor
The effect of caffeine on blood pressure is controversial. It may raise blood pressure by 10 mm Hg in individuals who hardly consume caffeine. However, it may have little or no effect on people who consume caffeine regularly.

To see its impact on you, monitor your blood pressure 30 minutes after having a caffeinated beverage. A rise in blood pressure by 5-10 mm Hg suggests that you are sensitive to caffeine.
