DASH diet

DASH Diet is ranked as one of the two healthiest diets to follow in 2018 (1).

Sharing the top spot with the Mediterranean Diet.

It's even outranking close to 40 other diets including the Weight Watchers Diet. 

What Is the DASH Diet?

"DASH" is short for Dietary Approaches to Stop Hypertension.

A condition that affects more than 1.1 billion people worldwide (2).

Researchers developed the DASH Diet to help people lower their blood pressure.

The diet emphasizes on eating veggies, fruits, lean meats, and whole grains.

These foods are known to prevent or reduce hypertension and lower the risk of heart disease. 

This is because high blood pressure is far less seen in vegetarian-based diets.

The diet also limits salt intakes, red meats, added sugars, and fat. 

A high intake of salt and red meats over time can lead to high blood pressure. Thus limiting them aids the condition. 

What Makes Dash Diet Healthier Than Other Diets?

First, it's medically created.

It was developed by the National Institutes of Health.

They wanted to create a nutrient-rich diet that would lower high blood pressure. 

As a result, DASH is rich in plant-foods and lean meats. Examples include fruits, vegetables, beans, fish, and chicken. 

Does Dash Diet Live up to Its Name?

Scientists and dietitians say yes.

Johns Hopkins University School of Medicine professor, Edgar Miller praises its effectiveness.  

Miller attests "The dash diet lowers blood pressure significantly." 

The DASH Diet Eating Guidelines

DASH doesn't have a pre-made meal plan or list of foods to shop, per se. 

Instead, it makes serving suggestions per food group. 

And the serving sizes are up to how many calories dieters need to reach their goal. 

Here are serving size suggestions for 2,000 calories a day diet.

No fruits are off limits on DASH. Fruits are naturally sweet, high in fiber, and low in calories and fat. 

  • Bananas
  • Apples
  • Mango
  • Pear
  • Pineapple
  • Berries (strawberries, blueberries, raspberries etc.)

Serving Examples:

  • 1 cup of skim milk

This includes chicken, fish and lean meat.

For red meat always choose lean cuts, and limit red meat to once or than twice per week.

Serving Examples:

  • 1 oz of cooked chicken, lean cut red meat or fish
  • One egg?

4–5 Servings of Seeds, Nuts, and Legumes Per Week

Nuts are certified superfoods and great on any diet.

They are full of fiber, protein, vitamins, and antioxidants that can lower your blood sugar. 

It can be any nuts from cashews, hazelnuts, almonds, walnuts, flax seeds, peanuts, to almonds. 

In particular, sunflower seeds make great healthy snacks. 

Flax seeds are awesome for smoothies as they add extra nutritional boost.

Legumes include kidney beans, lentils, and split peas. 

Serving Examples:

  • 1/3 cup of raw nuts
  • 2 tbsp of peanut or nut butter - no salt or sugar added. 
  • 2 tbsps of flax seeds or sunflower seeds
  • 1/2 cup of cooked kidneys

2–3 Servings of Fats and Oils Per Day

Olive oil, butter, safflower oil, avocado oil, coconut oil are all good.

They also recommend you choose low-fat mayonnaise and light salad dressing.

Serving Examples:

  • 1 tbsp of avocado oil
  • 1 tbsp of olive oil
  • 1 tbsp of mayonnaise
  • 2 tbsp of salad dressing

5 or Fewer Servings of Sweets per Week

The DASH diet limits added sugars to a very small amount.

Anything from candy, fruit juices, sodas, to table sugar is added sugar. 

Unrefined sugars such as alternative sugar like honey and agave nectar also belong in this category. 

Serving Examples:

  • 1 tbsp of sugar
  • 1 tbsp of spread jam
  • 1 cup of fruit juice

The takeaway here is that the DASH diet does not recommend you any specific foods. But instead, it's an eating habit that emphasizes on food groups and servings. 

Foods to Avoid

  • Foods high in saturated fat 
  • Fatty meats
  • Full-fat dairy
  • Tropical oils such as coconut, palm kernel, and palm oils
  • Sugar-sweetened beverages and sweets

To sum up, when following the DASH diet, you'll be eating a meal plan centered around foods that are:

  • Low in saturated and trans fats
  • Rich in potassium, calcium, magnesium, fiber, and protein
  • Lower in sodium

Potassium, in particular, is essential in balancing sodium, reports Harvard Public Health.

Reena Pande, M.D. Instructor in Medicine, Harvard Medical School confirms potassium-rich foods are linked to "lower blood pressure and lower risk of stroke".

This is one reason why you see a lot of vegetables and fruits on the DASH diet.

Its so you can increase your potassium intake by adding natural sources of potassium with limited sodium.

DASH diet eating guidelines

There are several main guidelines in the DASH diet to meet its aim to lower the blood pressure.  

The one that characterizes them the most and takes the highest importance in their diet is reduction of sodium.

There are two versions to the DASH diet:

  1. Standard DASH diet
  2. Lower sodium DASH diet 

While both versions of the DASH diet emphasize sodium reduction in your diet, each offers a different level of daily sodium allowance to meet your personal needs.

Note: both standards are for adults. 

  • Standard DASH diet: up to 2,300 mg of sodium a day
  • Lower sodium DASH diet: up to 1,500 mg of sodium a day 

The standard DASH diet's daily sodium allowance reflects the sodium intake guideline set by the Dietary Guidelines for Americans and represents the upper sodium limit of the DASH diet, while the lower sodium DASH diet has a sodium intake limit of 1,500mg a day, which represents the adequate sodium intake level for individuals ages 9 years and older. 

In the DASH study, the biggest improvement in blood pressure was found in the group that followed the DASH eating plan at the lowest level of sodium intake (1, 500mg/ day). 

To find a plan that meets your health needs, please consult with your doctor. 

Besides the sodium intake level, the DASH diet offers useful meal planning tips in the following areas: 

  • Food choices
  • Nutritional intake
  • Portion size

The DASH eating plan is flexible and requires no special foods. In fact, you'll be eating a lot of familiar foods on the DASH diet. 


Banana fruit

Recommended daily potassium intake for adults age 19 and older, set by the Food and Nutrition Center of the Institute of Medicine is 4.7 g. 

For moms who are breastfeeding, the number is slightly higher: 5.1 g a day. 

Because the listing of potassium is optional on the Nutrition Facts labels,  it may not always be apparent what foods carry how much of potassium.

For easy potassium food spotting, Harvard suggests to look for foods that don't carry a label. 

They include fresh produce, such as vegetables and fruits including leafy greens, orange vegetables, citrus fruits, as well as dried beans. They tend to contain the highest level of potassium.

To avoid too much sodium in your diet, stay away from banned products unless they are labeled low or no-sodium.

DASH diet: Portion Control 

Unlike other standard weight loss diets, the DASH diet does not impose a daily calorie limit. 

However, eating an appropriate amount of calories and not overeating is still a part of their way of eating. 

To plan your portions on the DASH diet, they provide a helpful the DASH diet log that outlines each food group's suggested portion size based on 1,600, 2,000 and 2,600 calorie a day diet. 

There are also a few other tips they provide regards to controlling calories. 

  • Eat smaller portions more frequently throughout the day.
  • Reduce the amount of meat that you eat while increasing the amount of fruits, vegetables, whole grains, or dry beans.
  • Substitute low-calorie foods, such as when snacking (choose fruits or vegetables instead of sweets and desserts) or drinking (choose water instead of soda or juice), when possible.

Another way to manage your portions on the DASH diet is to follow their serving suggestions per food group.
