The Link Between Nutrition and Hypertension

Introduction:

Nutritional intake plays a crucial role in maintaining the health of an individual. Nowadays, hypertension is one of the significant health issues being faced by many people including the youth and those falling above the age of 30 years. Elevated blood pressure is one of the major causes of cardiovascular diseases. This hypertension can lead to various life-threatening ailments. Controlling hypertension is essential and can be done primarily by regulating the diet.

What Is DASH?

Dietary Approaches to Stop Hypertension (DASH) is a healthy eating program developed to assist, treat or control high blood pressure, that is hypertension. The DASH diet contains items having sufficient amounts of potassium, calcium, and magnesium. All these nutrients support controlling blood pressure. The diet restricts food items with increased sodium, saturated fat, and extra sugars. Investigations have indicated that the DASH diet helps to reduce blood pressure within two weeks. The diet can also decrease LDL or low-density lipoprotein or bad cholesterol levels in the blood. High blood pressure and high LDL cholesterol are two significant risk elements for heart disorders and stroke.

What Is the Relation Between DASH Diet and Sodium?

The DASH diet is insufficient in sodium than a regular American diet. The American diet contains an enormous amount of sodium, that is, 3,400 milligrams (mg) of sodium per day. The standard DASH diet restricts sodium levels to 2,300 mg a day. It meets the proposal from the Dietary Guidelines for Americans to maintain standard sodium input of less than 2,300 mg per day. The DASH recommends a low dose of sodium to 1,500 mg per day for people suffering from severe hypertension.

What Is the Composition of a DASH Diet?

The DASH diet is an adaptable and proportional eating scheme that enables one to create a healthy heart. The DASH diet includes numerous vegetables, fruits, and whole grains. It contains fat-free or low-fat dairy products, fish, poultry, beans, and nuts. It does not allow high-fat foods, such as fatty meats and full-fat dairy products.

The following rules should be taken into consideration while adopting the DASH diet:

• Sufficient amounts of potassium, calcium, magnesium, fiber, and protein

• Low in saturated fat.

• Low in sodium.

What Are the Recommended Servings of the DASH Diet?

The DASH diet supplies day-to-day and weekly nutritive objectives. The number of servings depends on the daily calorie needs of the individual. For a 2,000-per-day calorie intake, the following are the suggested servings from food items:

• Grains: Six to eight servings per day are recommended. One serving includes one slice of bread, one ounce of dry cereal, and half a cup of cooked cereal, rice, or pasta.

• Vegetables: Four to five servings per day. One serving has one cup of uncooked leafy green vegetables, half a cup of cooked vegetables, or a half cup of vegetable juice.

• Lean Meats, Poultry, and Fish: Six servings per day. One serving has one ounce of cooked meat, poultry, or fish, or one egg.

• Nuts, Seeds, and Legumes: Four to five servings in a week. One serving comprises one-third cup of nuts, two tablespoons of peanut butter, two tablespoons of edible seeds like chia seeds and pumpkin seeds, or half a cup of cooked legumes such as dried beans or peas.

• Fats and Oils: Two to three servings per day. One serving has one teaspoon of soft margarine, one tablespoon of mayonnaise, one teaspoon of vegetable oil, or two tablespoons of salad dressing.

• Sweets and Added Sugars: Five or fewer servings per week. One serving includes one tablespoon of sugar, jelly, or jam or one cup of lemonade.

  • Fresh poultry, fish, and lean meat to be cooked without the skin.

  • Food labels should be checked.

  • Frozen food items can also be used.

  • Low-sodium or sodium-free food products should be consumed.

What Are the Other Dietary Options for Controlling Hypertension?

• Low-Fat Dairy: Dairy products containing common fat help in regulating blood pressure. Several studies have been conducted to check the daily intake of dairy products. The Rotterdam study indicates that intake of low-fat dairy products helps in the prevention of the commencement of high blood pressure.

• Nuts: The daily intake of nuts proves worthwhile in lowering blood pressure. In a Chinese study, it was found that an increased intake of nuts decreases the risk of evolving high blood pressure.

• Cocoa: Multiple studies have marked the association between cocoa intake and blood pressure. A recent study demonstrated that flavanol-rich cocoa products lower blood pressure in hypertensive patients.

• Tea: Several investigations also instructed that the intake of tea decreases blood pressure. Tea in any form, either green tea or non-green tea, lowers blood pressure or prevents raised blood pressure. Consumption of coffee by traditional coffee drinkers shows beneficial cardiovascular effects.

• Low Salt: Reduced intake of salt lowers blood pressure. Researchers have proved that reducing salt by consuming around 2,000 milligrams daily reduces the risk of elevated blood pressure in patients by five points.

• Potassium: The increased potassium intake diminishes blood pressure in hypertensive patients. The study has proved that increased potassium intake reduces blood pressure by five points.

• Vegetables and Fruits: Since ancient times, vegetables and fruits have been helpful to humans in preventing, managing, regulating, and treating various ailments. Vegetarians dependent on fruits and vegetables have lower risk of elevated blood pressure than those who eat meat and other products.

• Nordic Diet: The Nordic diet consists of whole grains, berries, fruit, vegetables, nuts, and low-fat dairy. The diet has been proven helpful in lowering blood pressure in hypertensive patients.

• Mediterranean Diet: The Mediterranean diet has proved helpful in managing cardiovascular diseases. The diet includes whole grains, vegetables, fruits, legumes, and moderate dairy and meat with low red meat.

Conclusion:

The primary risk factor for the evolution of cardiovascular disease is hypertension which is the leading cause of sudden and premature deaths around the globe (approximately 12.8 percent of global deaths). An increased systolic blood pressure (SBP) or diastolic blood pressure (DBP) by 20/10 mmHg makes twice as much the risk of cardiovascular disease. Therefore, methods and techniques to reduce blood pressure are necessary. The most regular and famous dietary therapy for controlling blood pressure is the Dietary Approaches to Stop Hypertension (DASH) diet. The DASH diet is prosperous in vegetables, fruits, and low-fat dairy items. It comprises the intake of nuts, fish, legumes, nuts, whole grains, magnesium, vegetables, fiber, potassium, and calcium.
