The Complete Beginner's Guide to the DASH . Diet

High blood pressure affects more than one billion people worldwide, and the number is growing. In fact, the number of people with high blood pressure has doubled in the past 40 years. This is a serious health problem, as high blood pressure is associated with a higher risk of conditions such as heart disease, kidney failure, and stroke. This article looks at the DASH diet, which is designed to fight high blood pressure and reduce your risk of heart disease.

The Dietary Approach to Stop Hypertension, or DASH, is a recommended diet for people who want to prevent or treat high blood pressure and thereby reduce their risk of heart disease. The DASH diet focuses on fruits, vegetables, whole grains, and lean meats. The diet came into being after researchers found that high blood pressure readings were much less common in people following plant-based diets, such as vegetarians and vegans.
That's why the DASH diet focuses heavily on fruits and vegetables while containing some lean protein sources like chicken, fish, and beans. Diet low in red meat, salt, sugar and fat. Scientists believe that one of the main reasons people with high blood pressure can benefit from this diet is that it helps reduce excess salt in the body.
The DASH Diet regularly recommends that users consume no more than 1 teaspoon (2,300 mg) of table salt per day, in line with most national food agency guidelines around the world. .

2.1 Lowering blood pressure Blood pressure is a measure of the force exerted on blood vessels and organs in the body when blood is transported throughout the body, blood pressure is calculated by two indicators:
Systolic blood pressure : Pressure in the blood vessels when the heart beats.
Diastolic pressure: The pressure in the blood vessels between heartbeats, when the heart is at rest.
Normal blood pressure for an adult is a systolic pressure of less than 120 mmHg and a diastolic pressure of less than 80 mmHg. This is usually written as systolic pressure above diastolic pressure, for example: 120/80.
People with a blood pressure reading of 140/90 are considered to have high blood pressure.
The DASH diet has the potential to lower blood pressure in both healthy and hypertensive individuals.
In studies, people following the DASH diet still had low blood pressure even when they didn't lose weight or limit their salt intake.
However, when salt intake is restricted, the DASH diet helps reduce blood pressure even more. The greatest reductions in blood pressure were seen in those with the lowest salt consumption. Furthermore, the low-salt DASH diet had the most dramatic results in people who already had high blood pressure, which reduced systolic blood pressure by an average of 12 mmHg and diastolic blood pressure by 5 mmHg.
In people with normal blood pressure, DASH reduces systolic blood pressure by 4 mmHg and diastolic blood pressure by 2 mmHg. This is in full agreement with other studies that have revealed that limiting salt intake can lower blood pressure, especially in people with high blood pressure.
However, lowering blood pressure does not always reduce the risk of heart disease
2.2 Weight loss If the user has been diagnosed with high blood pressure, it is most likely advised to lose weight as well. This is because the higher the weight, the higher the blood pressure. In addition, weight loss has been shown to have an effect on lowering blood pressure.
Some studies show that some people can lose weight with the DASH diet.
This result may be because the DASH diet cuts out a lot of foods high in fat and sugar, which are known risk factors for overweight and obesity.

2.3 Other health benefits Reduced cancer risk: A recent review found that people who follow the DASH diet have a lower risk of several cancers, including colorectal and breast cancers. risk of metabolic syndrome: Some studies note that the DASH diet reduces the risk of metabolic syndrome by up to 81% have a lower incidence of type 2 diabetes. Some studies demonstrate that it can also improve insulin resistance Reduce heart disease risk: In a recent review in women, following the DASH diet was associated with an increased risk of heart disease 20% lower and 29% lower risk of stroke. These benefits have been attributed to a diet high in fruits and vegetables during DASH.

While studies of the DASH diet determined that the greatest reductions in blood pressure occurred in people with the lowest salt intake, the benefits of salt restriction on health and longevity were unclear.
For people with high blood pressure, reducing salt intake significantly affects blood pressure readings. However, in people with normal blood pressure, the effect of reducing salt intake on blood pressure readings is much smaller.

Eating too little salt has been linked to health problems, such as an increased risk of heart disease, insulin resistance, and water retention.
On the DASH diet, users are advised to eat no more than 3/4 teaspoon (1,500 mg) of table salt per day.
In fact, a recent review found no link between salt intake and the risk of dying from heart disease, despite the fact that reducing salt intake can help lower blood pressure.
However, since most users today are eating too much salt, reducing salt intake from a very high 2 teaspoons 10 to 12 grams per day to 1 teaspoon (5 to 6 grams) every day can be beneficial. This goal can be easily achieved by reducing the amount of processed foods in the diet and eating mostly whole foods.

The DASH diet does not list specific foods to eat. Instead, recommend specific servings of different food groups.

Eat lots of vegetables and fruits . Swap refined grains for whole grains. Choose fat-free or low-fat dairy products. Choose lean protein sources like fish, poultry, and beans. Use vegetable oil. Limit your intake of foods high in sugar, like soda and candy. Limit your intake of foods high in saturated fat like fatty meats, full-fat dairy, and oils like coconut and palm oil. Outside of measured servings of fresh fruit juices, the diet recommends low-calorie beverages like water, tea, and coffee.
