ARTICLE SUMMARY

Discovering the right diet for your health goals can often feel like navigating a maze. Top contenders include the DASH Diet, the Mediterranean Diet, and a blend of the two: the MIND Diet. While you might be familiar with these dietary plans, understanding their differences and finding the best fit can be puzzling.

As a Registered Dietitian Nutritionist and the author of the cookbook MIND Diet for Two, I often field questions about all of these diets. In this article, I’ll break down each diet, outline its core principles, recommended foods, and what to limit. We’ll weigh the pros and cons of each approach, and look at which may suit your situation the best.

I’ll also share practical tips for adopting these diets seamlessly into your lifestyle and highlight my go-to resources for more information and delicious recipes.

What is the DASH Diet?

Dietary Approaches to Stop Hypertension (DASH) is an eating plan rich in colorful fruits and vegetables, low-fat dairy foods, poultry and fish, and nuts and seeds. 

Research in the 1990s found that people with elevated blood pressure who followed an eating plan high in fruits, vegetables, and low-fat dairy products and low in saturated fat could significantly reduce their blood pressure. 

Remarkably, their blood pressure was lower after just 2 weeks of following the diet and remained lower throughout the eight weeks they followed it.

Why is this research important? This study, and subsequent studies, show that we can lower blood pressure significantly by making diet changes that don’t focus only on reducing sodium. Much more than the salt shaker affects your blood pressure!

Foods Encouraged on the DASH Diet

The DASH diet focuses on foods high in potassium, calcium, magnesium, and fiber and encourages minimizing your sodium intake. While not a strict diet, this eating plan recommends specific servings of fruits, vegetables, whole grains, and dairy foods daily.  

Foods to Avoid on the DASH Diet

While not overly restrictive, the DASH diet recommends limiting foods that are high in saturated fat, sugar, and sodium. Foods commonly recommended to avoid or limit are:

• Fried Foods: French fries, chips, and fried chicken
• Sweets: Sugary sodas, sweetened teas and coffee, and desserts
• High Sodium Foods: Salted chips, regular canned soups or packaged meals, deli meats, hot dogs, and jerky.
• High-Fat Foods: Sausage, bacon, fatty cuts of red meat, cream, butter, cheese, and ice cream. 

Pros of Following the DASH Diet

There are many benefits you can get from following the DASH diet.

• Lowered Blood Pressure
• Weight Loss
• Lowered Risk of Stroke
• Reduced Cholesterol
• Improved Energy
• Better Sleep
• Reduced Constipation

Cons of Following the DASH Diet

There are few cons to following the DASH diet; however, if you are lactose intolerant or have a milk allergy, choose plant-based dairy alternatives. Similarly, if you have other food allergies to nuts or soy, you will need to choose alternatives.

Another issue is that the diet requires a little more planning and time in the kitchen, but with some planning, that should be minimal. 

Finding foods that fit this diet may be slightly more difficult when eating out than with other diets, but with practice and a few tips (see below), you can certainly enjoy a nice restaurant meal!

Now, let’s look at another “top diet” that is routinely touted for its health benefits. 

What is the Mediterranean Diet?

This diet is based on the eating patterns of people who live in countries surrounding the Mediterranean Sea, like Italy, Spain, Morocco, and Greece. It is rich in fruits and vegetables, whole grains, seafood, olive oil, and legumes. It includes a little red wine (yay!), poultry, and a little red meat. 

Researchers realized there might be something to how the people in Mediterranean countries ate and lived that contributed to their longevity. 

A few years ago a paper came out about “The Blue Zones.” The Blue Zones are parts of the world that have a higher percentage of people who live to over 100 than other parts of the world. Two areas are in the Mediterranean: Sardinia, Italy, and Ikaria, Greece.

What do they have in common? There are seven key areas, but one main one is the types of foods they enjoy. 

Compared to the average American diet, people in these countries ate more whole foods and less processed foods. They ate more greens, beans and legumes, fruits, and a variety of seafood. 

And even though they used a fair amount of olive oil and cheese – which seems counterintuitive to the low-fat recommendations of the 80s and 90s –  they still enjoyed a longer and more active life than Western cultures. 

Research shows that people who follow the Mediterranean diet have a major advantage in health outcomes compared to those who follow an average American diet.  Those following a traditional Mediterranean diet had lower rates of heart disease, diabetes, obesity, and dementia. 

The Mediterranean diet consistently ranks as the best overall diet for health in US News & World Report and the Annual Best Diets Report because it’s a well-rounded, healthy meal plan. The research consistently shows those who follow it have lower rates of heart disease, diabetes, cancer, and other chronic diseases. 

As a registered dietitian, I always want to empower my clients to find an eating plan that supports their long-term health and wellness and is sustainable. 

Foods Encouraged on the Mediterranean Diet

The Mediterranean diet focuses on including more plant-based foods while still incorporating animal-based items like seafood, poultry, eggs, low-fat dairy products, and a limited amount of lean meat. Below is a general guide for the types of foods and servings suggested per day. Keep in mind that this is just a guide to help you get started.

Foods to Avoid on the Mediterranean Diet

While most foods are allowed on the Mediterranean diet, you are encouraged to limit some. Those include:

• Red Meat (no more than 1 – 2 times a week)
• Sweets
• Fried Foods

Pros of Following the Mediterranean Diet

Like the DASH diet, the Mediterranean diet offers many benefits. 

• Lowered Risk of Cardiovascular Disease
• Lowered Risk of Type 2 Diabetes
• Weight Loss
• Improved Energy Levels
• Lowered Risk of Dementia
• Improved GI Health

Cons of Following the Mediterranean Diet

There are very few cons to following the Mediterranean diet. 

• Some people may find it takes more time to prepare meals because they use fewer processed foods and may need to make more frequent trips to the store or farmer’s market. Because the diet includes more whole foods and fewer processed items, some worry it may be more expensive to follow. 

• For some people of other cultures, the diet may include unfamiliar foods, while foods they typically enjoy may not be mentioned. Finding ways to enjoy cultural foods in this diet can be challenging. 

• Some foods, like vegetables, offer enough variety that most people can easily incorporate familiar foods into their days. Others, like olive oil, can be more challenging.

However, with some pre-planning and meal prepping, you can overcome these challenges. Download my Mediterranean Diet Pantry List for ideas on how to stock your fridge and pantry so you will have the ingredients you need on hand to make healthy Mediterranean meals.   

We’ve discussed two impressive diets that can help you live a vital, healthy life. Let’s dive into my favorite. It’s a mash-up of these two!

What is the MIND Diet?

The MIND Diet (Mediterranean-DASH Intervention for Neurodegenerative Delay) combines the Mediterranean and DASH diets but focuses on a few specific foods that are known to improve brain health and reduce the risk of dementia. If you follow me, you know the MIND Diet is a huge interest of mine, and I’m a big proponent of it. 

Researchers at Rush Presbyterian Hospital in Chicago compared this diet to the Mediterranean and DASH diets with independently living elderly people. They found all diets reduced cognitive decline, but those who followed the MIND diet strictly had a 53% reduced risk of developing Alzheimer’s disease.  

Even more remarkable, those who only partially followed the MIND diet had a 35% lower risk of developing the disease. Neither the Mediterranean nor the DASH diet showed these impressive results on its own. 

What does this mean? Even if you implement only a few principles regularly, you could still see the diet’s benefits. 

Foods Encouraged on the MIND Diet

The biggest difference between the MIND diet and the DASH and Mediterranean diets is its focus on foods shown to support brain health. Berries and leafy greens are the two main examples of foods emphasized in this diet. 

Foods to Avoid on the MIND Diet

While this isn’t a strict diet and there aren’t foods you need to completely avoid, the MIND diet does recommend limiting foods that are high in saturated fats, trans fats, and sugar as these are detrimental to brain health. 

• High Saturated Fat Foods: Cheese, red meat, cream, butter
• Foods High in Trans Fat: Fried foods, tropical oils
• Sugary Foods and Sweets: Cakes, cookies, pies, sweetened beverages

Pros of Following the MIND Diet

You may experience many benefits beyond brain health when following the MIND diet.

• Lowered Risk of Cardiovascular Disease
• Improved Mood
• Weight Loss
• Improved Energy Levels
• Better Sleep
• Improved GI Health

Cons of Following the MIND Diet

There are few risks or cons associated with this diet; however, some people should not follow it. Because it is high in leafy greens and vitamin K, people taking a blood thinner should not suddenly start this diet. 

Also, people with kidney disease should talk with their Registered Dietitian Nutritionist and Physician to determine if this diet is appropriate. 

Like the other two diets, making these changes may feel overwhelming and like a lot of work. There are several easy ways you can start incorporating some of these principles today.  

To help you get started, I’ve created a 7-day meal plan that includes some of my favorite recipes and a shopping list. Download it here. 

Which Diet is Better for You?

All three diets are consistently ranked among the best for overall health. They are all healthy diets and encourage an increased intake of fruits, vegetables, whole grains, seafood, and nuts and seeds. 

Most Americans would benefit greatly from making nutritional changes in line with any of these three diets, but some differences may make one better for you than another. Let’s look at key areas for health and longevity.

For my Brain Health?

The MIND diet has significant research backing its ability to help slow cognitive aging and protect brain health. 

Because the MIND diet specifically emphasizes foods known to support brain health, like berries and leafy greens, and limits those known to be detrimental to brain health, this dietary plan is the clear winner over the other two diets. 

That said, the MIND diet combines elements of the Mediterranean and DASH diets. Both of these diets also have research supporting their ability to reduce cognitive aging and support brain health. 

While some research found improvements in cognitive health with a Mediterranean diet supplemented with antioxidant-rich foods, other short-term studies have not had the same results. 

The DASH diet has also shown conflicting results. Over the years, some studies have shown improved brain function and slower cognitive decline, while other studies have not seen the same results. 

For people with a history of dementia in their families, the MIND Diet may be the best choice, but following any of the three is a better option than a traditional American diet for brain health. 

What about for my Heart Health?

For overall heart health and reducing the risk of heart disease, the Mediterranean diet has the most supporting research. 

Early observational studies and follow-up research found that those following a Mediterranean-type diet had a significantly lower risk of a cardiovascular event than those following a reduced-fat diet. 

Specifically, the Mediterranean diet supplemented with olive oil or nuts showed the greatest decline in heart attacks and strokes. 

In addition, the Mediterranean Diet lowered other Cardiovascular risk factors, including waist circumference, blood lipid levels (cholesterol, LDL cholesterol, and triglycerides), inflammation, and blood glucose levels. 

Or my Blood Pressure Control?

The DASH Diet has been shown to significantly lower blood pressure and is now recommended as a first-line treatment for blood pressure reduction. Your healthcare team may also recommend medication, but your dietary choices have a huge impact on your blood pressure.

The original DASH diet study found that people with slightly elevated blood pressure (systolic blood pressure of 160 mm Hg or less and diastolic blood pressure of 80 to 95 mm Hg) who followed the diet for just 2 weeks saw significant reductions in blood pressure that continued throughout the study. 

Want even better Blood Pressure results? When the DASH diet is combined with a modest reduction in sodium intake, blood pressure levels are lowered even further. 

While both the Mediterranean and DASH diets reduce blood pressure, the DASH diet wins when comparing the two.

If you are at risk for high blood pressure, the DASH diet may be for you. Talk with your doctor and registered dietitian nutritionist to see whether incorporating DASH recommendations into your life is worth a try. 

Let’s not forget about Weight Loss

All three of these diets, the DASH diet, Mediterranean Diet, and MIND diet, appear to support weight loss and weight maintenance. 

The DASH diet has been shown to support weight loss, especially when combined with a lower-calorie intake and exercise. The diet is high in fiber and low in fat and sugar, so for many people, this alone can support weight loss. 

The Mediterranean diet has also shown positive effects on both weight loss and weight maintenance, with reports that people who adhere to the Mediterranean diet have twice the likelihood of maintaining their weight loss compared with those who only partially follow it. 

A recent study of over 1000 adults found that those with greater adherence to the MIND diet were 31% less likely to be obese than those with lower adherence. They also were 42% less likely to have elevated triglyceride levels than those partially following the diet. 

Why is this important? Abdominal weight gain and elevated triglycerides are often indications of a higher risk of insulin resistance and metabolic syndrome. Reducing weight and your triglyceride levels can help lower your risk of developing type 2 diabetes and heart disease. 

All three diets are healthy and emphasize fruits and vegetables, whole grains, and fiber-rich foods, while encouraging reduced intake of sugar, fried foods, and saturated fat. These changes all help support weight loss and weight maintenance, especially when combined with exercise and other lifestyle changes. 

FAQs

While each of these is labeled a “diet,” they are all flexible and easy to follow. Instead of “diets,” I like to think of them as eating plans or styles. 

Here are a few questions I’m often asked, along with tips for incorporating these plans into your daily life. 

Which is best for you to follow?

It depends on your health risk and your goals. This chart gives a quick overview of the main health benefits of each diet. 

Can you eat out on these diets?

You can certainly eat in restaurants while following any of these plans. Restaurants are making it easier by offering more plant-based entrees, salads, and customizable dishes. A few things you can do when eating out are:

• Choose entrees that include seafood, lean meat, or poultry.
• Ask for extra vegetables or a side salad. 
• Choose a vinaigrette dressing instead of a creamy dressing.
• Enjoy a dessert once in a while, but not every time you eat out.

How can I get started?

Start with something easy to do. Maybe it is simply adding a handful of berries to your yogurt or oatmeal in the morning or enjoying a snack of nuts and dried fruit in the afternoons. 

Another tip is to do some meal prep early in the week (or whenever fits your schedule best). Cut up vegetables to snack or to use in meals throughout the week. 

• Pepper strips can be added to salads, and fajitas or sauteed with tomato sauce and chicken breasts. 
• Wash lettuce and portion it into individual containers for salads.
• Segment oranges and store them in containers to toss into grain salads or mix with berries for fruit cups.
• Cook a batch of grains like rice, barley, or farro to use in salads or entrees throughout the week.
• Make overnight oats or baked oatmeal to enjoy for a quick breakfast. 

Do I have to be perfect?

You don’t need to be perfect when following any of these diets. Aiming for perfection often just increases your stress level, which also isn’t healthy! The goal is to make small, sustainable changes that become habits. (You can read more about how to do that in my post “10 Sustainable Habits for the New Year.”)

Even people who only partially followed each of these diets reduced their risk of heart disease, lowered their blood pressure, and reduced their risk of dementia. 

Remember, small changes can make a big difference in your long-term health!

Bottomline

The differences between the DASH, Mediterranean, and MIND diets are minimal but important, and the right one for you depends on your risk or concerns about different health conditions. As a registered dietitian, I believe all three are healthy eating patterns and recommend each for different reasons.
