Hypertension (High Blood Pressure)

High Blood Pressure

Whenever your heart beats, it pumps out blood into the arteries, blood pressure is the force of the blood pushing against the walls of the arteries. The blood pressure is highest when the heart beats, pumping the blood, this is called systolic pressure. When the heart is at rest, between beats, the blood pressure falls. This is the diastolic pressure. It is measured in millimeters of mercury (mm Hg).

High blood pressure, also called hypertension in an adult occurs when the blood pressure is greater than or equal to 140 mm Hg systolic pressure or greater than or equal to 90 mm Hg diastolic pressure. 120/80 mm Hg or lower is normal blood pressure and 120 and 139 mm Hg systolic or between 80 and 89 mm Hg diastolic is prehypertension.

In addition to diet and exercise, the doctor may recommend medication to lower blood pressure. The medication that would be prescribed by your doctor depends on the stage of high blood pressure and whether or not you also have other medical conditions. To reduce the number of doses you need a day, which can reduce side effects, the doctor may prescribe a combination of low-dose medications rather than larger doses of one single drug.

Reducing sodium in the diet

  • Develop an inclination for low salt food by using very little or no salt at all when preparing your meals. Avoid using table salt.
  • Avoid fast foods and restaurant foods as they use very high salt.
  • Avoid ketchup, pickles, olives, all sauces, commercially prepared or cured meats or fish, canned foods (eat fresh foods), salted nuts, peanut butter, chips, popcorn and snacks.

Diet suggestions:

  • Low-sodium diets are prescribed to help control high blood pressure. These diets limit the amount of sodium in the diet to less than 2 grams daily, that is about half the amount of sodium in the average diet.
  • Use herbs and spices instead of salt for seasoning. Use garlic, lemon and lime juice, garlic, dill weed, basil, curry powder, turmeric, cumin, black pepper, or vinegar to improve the flavour and aroma of foods.
  • Add a pinch of sugar or a squeeze of lemon juice to bring out the flavour in fresh vegetables.
    Rinse canned vegetables with tap water before cooking.
  • Substitute unsalted, polyunsaturated cooking medium for butter or ghee.
