Cardiologist Recommended Foods to Prevent Heart Attacks

Heart disease is a leading cause of mortality worldwide and prevention is extremely important. Dr. Jack Wolfson has dedicated his career to understanding the best dietary choices for the health of the heart. Drawing from years of clinical experience, he shares his top five foods to prevent heart attacks.

1. Seafood: Nature’s Heart Protector

Seafood stands at the top of the list for a healthy heart. Rich in essential nutrients, seafood is a powerhouse for preventing heart attacks. The vitamins, minerals, proteins, and fats in seafood are vital, especially fatty acids EPA and DHA that are found primarily in fish.

The Importance of EPA and DHA

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are omega-3 fatty acids and play a crucial role in cardiovascular health. DHA is integral to cell membranes throughout the body. Various researches show that people with higher levels of DHA in their blood have a significantly lower risk of heart attacks.

Best Seafood Choices

For optimal heart health, Dr. Wolfson recommends consuming the following:

  • Wild salmon
  • Sardines
  • Anchovies
  • Clams
  • Oysters
  • Shrimp
  • Lobster
  • Crab
  • Wild salmon roe

These seafood options provide a combination of beneficial nutrients without the high levels of contaminants found in other fish. Incorporating seafood daily in your diet can significantly enhance heart health. While fish oil supplements are available, Dr. Wolfson suggests eating whole fish to maximize nutrient intake.

2. Organ Meat: Nutrient-Dense Powerhouse

Organ meat from free-range, grass-fed animals are incredibly beneficial for heart health. While muscle meat is nutritious, organ meats contain higher concentrations of essential vitamins, minerals, proteins, and fats.

Benefits of Organ Meat

Organ meat, such as liver, heart, and kidney, is full of coenzyme Q10 (CoQ10), which is vital for mitochondrial function. CoQ10 helps boost glutathione, an antioxidant that reduces inflammation and oxidative stress—both closely linked to cardiovascular disease.

To harness the benefits, Dr. Wolfson highlights the following as the best options:

  • Bison liver
  • Bison heart
  • Bison kidney

Including organs in your diet one to three times per week, or taking organ supplements daily, can significantly improve heart health. These practices emulate the dietary habits of our ancestors, who consumed a lot of organ meat.

3. Avocados: Heart-Healthy Fats and More

Avocados, or “avocardios,” are another fantastic food for the heart. They are rich in quality fats, fiber, vitamins, and minerals.

Nutritional Profile of “Avocardio”

Avocados are high in:

  • Healthy fats: These fats help lower bad cholesterol levels and are essential for heart health.
  • Fiber: Helps maintain a healthy digestive system and can reduce cholesterol levels.
  • Vitamin C and E: Antioxidants that protect the heart.
  • Magnesium and Potassium: Crucial minerals for heart function.
  • Phytonutrients: Compounds that have various health benefits, including anti-inflammatory effects.

Incorporating Avocados in Your Diet

Dr. Wolfson recommends eating avocados almost daily. They can be added to salads, smoothies, or enjoyed on their own. Avocado oil is also a good alternative for cooking, but the whole fruit provides the most benefits.

4. Eggs: Nature’s Nutrient-Rich Cocoon

Despite common misconceptions, eggs are excellent for the heart. They are a complete source of nutrition, containing all the essential vitamins, minerals, protein and fats needed for a developing chick.

Cholesterol in Eggs

Eggs have cholesterol, but this is not something to fear. Cholesterol is necessary for the body’s healing processes, including after a heart attack. The human body and many animals produce cholesterol, which is crucial for many bodily functions.

Choosing the Right Eggs

For maximum health benefits try to consume free-range, pasture raised organic eggs. These eggs are more nutritious and free from harmful additives often found in other eggs. If possible, raising backyard chickens ensures a steady supply of high-quality eggs.

5. Beets and Green Leafy Vegetables

Beets, along with green leafy vegetables, are rich in nitrates, which the body converts to nitric oxide—a potent vasodilator. Nitric oxide helps open blood vessels, improving blood flow and reducing blood pressure.

The Role of Nitric Oxide

When consuming beets and green leafy vegetables, the nitrates are converted by oral bacteria into nitrites and then into nitric oxide in the stomach. Nitric oxide is a natural vasodilator, akin to how nitroglycerin works in emergency heart treatments.

How to Include Beets in Your Diet

Dr. Wolfson suggests making beet-rich salads, using ingredients like:

  • Beets
  • Olive oil
  • Lemons
  • Capers
  • Anchovies (optional)

Beets can turn urine and stool red, a harmless side effect known as beeturia. This can also serve as a reminder to check your body’s reaction and ensure there are no other underlying issues.

Green Leafy Vegetables

In addition to beets, adding green leafy vegetables like spinach, kale, and arugula in your diet provides additional nitrates and essential nutrients. These vegetables support overall cardiovascular health.


Making the best choices about the foods you consume and through the correct diet is one of the best ways to prevent heart attacks. By eating seafood, organs, avocados, eggs, and beets, you can significantly lower your risk of heart disease. These foods provide essential nutrients that support the health of the heart, reduce inflammation, and improve overall well-being. As Dr. Wolfson’s experience shows, these dietary changes can be life-saving.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
