1. How can the DASH diet help you?

Even if you don't have high blood pressure, the DASH diet is worth considering. It can help you lose weight because it is a healthy diet.
You won't feel hungry, the DASH diet enhances green vegetables, fruits and low-fat dairy products while cutting fat, cholesterol and sweets.
Following the DASH diet, your blood pressure can drop by a few mmHg in just 2 weeks. In the long term, your systolic blood pressure can drop by 8 to 14 mmHg, which significantly reduces health risks.
Since the DASH diet is a healthy way of eating, it has many health benefits besides lowering blood pressure. It is also the recommended diet for the prevention of osteoporosis, cancer, cardiovascular disease, stroke and diabetes.

2. How is the DASH diet done?

2.1 Reduce salt intake, reduce salt Eating salty causes your body to increase water retention, which increases blood volume, putting extra pressure on your heart. With the DASH diet you will reduce your sodium intake to 2300 mg or less to 1500 mg/day, depending on your health, age, ethnicity and comorbidities.
The American Heart Association recommends a sodium level of less than 1500 mg/day for all adults. If you are not sure which amount of sodium is right for you, consult your doctor.
Here are some ways to cut down on salt in your daily diet:
Choose foods and spices with little or no sodium Limit processed or processed foods, smoke or pickling Limit processed foods (processed foods often contain a lot of sodium)

2.2 Eat a variety of whole grain foods: 6-8 servings per day Includes bread, cereal, rice and pasta. Example 1 serving includes: 1 slice of whole-grain bread, 1 ounce (
28 grams) of dry cereal, or 1/2 cup of cooked cereal, rice, or pasta.
Choose whole grains because they contain more fiber and nutrients than refined nuts. For example, use brown rice in place of white rice, and whole grain pasta and bread in place of regular pasta and bread. They often have a “100% whole grain” label on the package. This type of food is usually low in fat. Do not serve with butter, cream and cheese sauce. 2.3 Green vegetables: 4-5 servings/day Tomatoes, carrots, broccoli, sweet potatoes and other vegetables are high in fiber, vitamins and minerals like potassium and magnesium. For example, 1 serving consists of 1 bowl of raw vegetables or 1/2 bowl of chopped or cooked vegetables.
Don't think of vegetables as just a side dish – a plate of mixed vegetables with brown rice or wholemeal noodles can serve as a main meal. Fresh and refrigerated vegetables are both good choices. When buying frozen or canned vegetables, choose those labeled low-salt or no-salt. To increase your vegetable intake for a day, for example, in a vegetable stir-fry you can halve the meat and double the vegetables.

2.4 Fruits: 4-5 servings/day Many fruits are easy to make as part of a main or side meal, like green vegetables, they contain a good amount of fiber, potassium, magnesium and low amounts of fat. – coconut is the exception. For example, 1 serving includes 1 medium fruit, 1/2 cup fresh, frozen or canned fruit, or 4 ounces (
120 ml) of juice.
Add 1 piece of fruit to a main meal and 1 piece to a snack, then add a fruit dessert with some low-fat yogurt. Do not peel if possible. The skins of apples, pears and most other fruits contain good amounts of fiber and nutrients. Watch out for citrus fruits and juices like grape juice, which can interact with some medications. Check with your doctor or pharmacist to make sure they are safe for you. If you choose canned fruit or juice, choose one without added sugar.

2.5 Dairy products: 2-3 servings/day Milk, yogurt, cheese and other dairy products are the main sources of calcium, vitamin D and protein. But it's important to make sure you choose low-fat or fat-free dairy products because they can contain large amounts of fat — and mostly saturated fat. For example, 1 serving includes 1 cup of fat-free milk, 1 cup of low-fat yogurt, and 1.5 cups of 1-part skimmed cheese.
If you have digestive problems when consuming dairy foods, choosing products that do not contain lactose or can take over-the-counter medications containing the enzyme lactase, can reduce or prevent symptoms of lactose intolerance. Reduce or avoid regular cheeses, even fat-free cheeses, and they are often high in sodium.

2.6 Meat, poultry and fish: 6 or less daily servings Meat can be a rich source of protein, B vitamins, iron and zinc. Choose lean meat and no more than 170 grams of meat per day. Cutting down on your meat will allow for more veggies.
2.7 Nuts and dried beans: 4-5 servings per week Almonds, sunflower seeds, legumes... are good sources of magnesium, potassium and protein. They are also full of fiber and phytochemicals. These plant compounds may protect against certain cancers and heart disease.
However, they should only be used a few times a week because they contain a lot of calories. Examples of a serving include 1/3 cup of nuts, 2 tablespoons of nuts, or 1/2 cup of cooked beans or peas.
2.8 Fats and Oils: 2-3 servings a day Fats help your body absorb essential vitamins and help your body's immune system. But too much fat increases the risk of heart disease, diabetes and obesity. The DASH diet establishes a healthy nutritional balance by limiting total fat intake to less than 30% of daily calories, focusing on monounsaturated fats.
2.9 Sweets: try to limit yourself to 5 servings per week You don't have to completely eliminate sweets while following the DASH diet. For example, one serving includes 1 tablespoon sugar, jelly or jam, 1/2 cup sorbet...
2.10 Get enough potassium

Potassium is another important part of the DASH diet. Getting enough of this mineral can help lower your blood pressure. It's best to get your potassium from foods rather than supplements. The goal is 4,700 milligrams (mg) per day. Try these potassium-rich foods:
Potatoes: 610 mg Sweet potatoes: 542 mg Bananas: 422 mg Avocado (1/2): 487 mg Cooked spinach (1/2 cup): 419 mg Get started Currently the DASH diet is not difficult but you do have to make some changes.
Start by keeping a food diary for a few days and see how your diet goes. Then start making changes. You would aim for about 2,000 calories per day.
That may vary depending on your body condition and your activity level.
