Dietary Approaches to Help Control Hypertension

, ,

 

One of the most common reasons for hypertension and the risk of heart disease among Canadians is due to a person’s diet. Simply, many of us are consuming far too much salt, fat and sugar that can affect our health, quality of life and overall longevity.

To combat this, researchers and heart-related organizations have developed a dietary plan called, Dietary Approaches to Stop Hypertension, or what is known as the DASH diet. The diet consists of vegetables, fruit, whole grains, low-fat dairy products and a lower level of salt.  Dietitians of Canada states that DASH can even be as effective as some medications in helping keep blood pressure levels in a normal range.

Why is a healthy blood pressure important?

High blood pressure and carrying excess weight on your body, causes the heart to work harder to pump nutrient- and oxygen-rich blood to the body. The arteries that deliver the blood become scarred and less elastic. Although these changes happen to everyone as they age, they happen more quickly in people with high blood pressure. As the arteries stiffen, the heart has to work even harder, causing the heart muscle to become thicker, weaker and less able to pump blood. When high blood pressure damages arteries, they are not able to deliver enough blood to organs for their proper functioning.

DASH

To help walk us through this diet, we’ve asked our Registered Dietitian, Marsha Rosen, to explain its components and what a normal day would be like on the DASH diet.

The DASH diet emphasizes making meal and snack choices from the following Food Groups:

  • Vegetables
  • Fruit
  • Grains
  • Low Fat or No-Fat Dairy Foods
  • Lean meats, poultry and fish
  • Nuts, seeds and dry  legumes
  • Fats and oils

The DASH Eating Plan outlines what you would eat normally if you followed a 2000 calorie a day diet.

In addition to focusing on these key food areas, the DASH eating plan encourages you to eat foods that are high in potassium, calcium and magnesium.

Potassium – Good sources of potassium include tomatoes, bananas, oranges, potatoes, nuts, lentils, beans, milk and fish.

Magnesium – Good sources of magnesium include spinach, whole grain cereals, nuts, seeds, fish, beans, soy and lentils.

Calcium – High amounts are found in milk, yoghurt, canned fish with bones mashed in, leafy green vegetables, beans and tofu (manufactured using calcium salts).

And finally – all of this is a wonderful beginning to lifelong healthy eating habits – the one other key step is to introduce some regular exercise that is personally enjoyable and done regularly. Get some professional help if you need it to start you on an appropriate program.
