Nutrition for Heart Health: Guidance from a Long Island Registered Dietitian

Cardiovascular and cardiometabolic diseases are on the rise, and with them, the importance of sound, science-backed nutrition guidance. As a Registered Dietitian Nutritionist (RDN), I help patients manage blood pressure and cholesterol levels, reduce cardiovascular risk, and adopt sustainable lifestyle changes rooted in evidence — not trends.

Unfortunately, misinformation about nutrition is rampant — especially on social media. Online “experts” often promote advice that contradicts established guidelines and can lead to confusion, unhealthy behaviors, and misplaced distrust of credentialed professionals. This is why it’s essential to seek out reliable, credible sources when it comes to your health.

What Is a Cardiovascular Dietitian?

I am a nutrition professional with the only nationally and state recognized credentials. As an RDN and New York State Certified Dietitian Nutritionist (CDN), I specialize in preventing and managing cardiovascular conditions such as:

  • Hypertension
  • Coronary artery disease
  • High cholesterol
  • Congestive heart failure

I offer individualized support and virtual medical nutrition therapy (MNT) to help clients meet their health goals through sustainable dietary and lifestyle strategies.

What Does Medical Nutrition Therapy for Cardiovascular Health Involve?

MNT is a comprehensive, personalized approach to improving heart health. It includes:

  • Nutrition education and label reading
  • Heart-healthy meal planning
  • Dietary pattern adjustments (e.g., Mediterranean, DASH)
  • Lifestyle and eating behavior recommnedations
  • Macronutrient and micronutrient optimization
  • Sodium and alcohol reduction
  • Support for weight management
  • Guidance on physical activity integration
  • Food and recipe modifications
  • Ongoing monitoring and support

Heart-Healthy Diet Plans — Backed by Science

Nutritional strategies that support cardiovascular health emphasize:

  • Fruits and vegetables
  • Whole grains
  • Legumes, nuts, and seeds
  • Lean proteins, especially fish
  • Healthy fats like olive oil
  • Minimizing added sugars and salt, and saturated and trans fats

Evidence-based patterns such as the Mediterranean diet, DASH diet, and plant-forward vegetarian approaches have been shown to reduce cardiovascular risk. These are not fad diets — they are sustainable, flexible frameworks rooted in decades of research.

Heart Disease Affects Women, Too

It’s a common myth that cardiovascular disease is a “man’s problem.” Studies have now shown that 30% of deaths in women are caused by CVD, exceeding all types of cancer combined.

While the foundational principles of a heart-healthy diet apply broadly, women may have unique nutritional needs, especially during menopause or when managing other risk factors. Working with a Registered Dietitian Nutritionist means receiving tailored guidance that considers your health history, lifestyle, and goals.

[h2] Support That Makes a Difference

Heart disease is largely preventable — and manageable — with the right tools and support. As an RDN, I help clients:

  • Make informed food choices
  • Manage risk factors like high cholesterol and blood pressure
  • Build personalized meal plans
  • Learn about healthy, and delicious, food options

If you’re ready to take a proactive step toward protecting your heart, I offer individualized medical nutrition therapy online, with flexible options to meet your needs.

Over the past six months that I have been seeing Nacny, she has been very helpful in hepling me lose 31 pounds. She understands very aspect of what I needed and how to accommidate them properly. With Nancy's help I have been able to change my lifestyle, eat healthier and change and treat my medical conditions very differently and for the best. I would highly reccommanded Nancy to anyone that has tried diets before and has not succeded and who has a lot of different medical conditions that make it difficult to know what to eat and what not to eat.

I was hesitant at first to start seeing a nutritionist. I was very comfortable with my poor eating habits despite being upset about my weight; however I knew I needed to make a change.

Nancy was very understanding from the start. Before meeting with Nancy, I had been in a constant cycle of over-restricting myself to lose weight rapidly, followed by binge eating and gaining it all back plus some more.

Over the past year and a half, Nancy has helped me discover normal eating. She helped me understand my hunger and my fullness in addition to helping me choose better food options.

Nancy is very dedicated to working with you and helping you achieve your goals. She doesn’t just help you reach your goals — she helps you change your perspective of food and eating for the better. What you learn with Nancy is not temporary — you will carry it with you and practice it throughout your life.

I have lost almost 70 pounds since first meeting with Nancy and continuing on my journey. I highly recommend working with her.

Nancy, thank you for all of your help!

Although I was unlucky when I developed some health issues, I was very lucky to find Nancy Mazarin, a skilled, intelligent, caring nutritionist. I saw lots of doctors but she was the one who came up with the diagnosis that finally led to my improved health. She was always available when I had questions and was even willing to meet with me one weekend when I was struggling.
