Want to Avoid Cardiovascular Disease? This Is What The Science Says


Two recent nutrition studies have highlighted the significant impact of dietary choices on cardiovascular health, raising important questions about what constitutes a heart-healthy diet and which foods to avoid to lower the risk of cardiovascular disease.

Plant-Based Meat Substitutes vs. Animal Meat

A study published in The American Journal of Clinical Nutrition on April 8, 2024, conducted by researchers from the Singapore Institute of Food and Biotechnology Innovation and the Agency for Science, Technology and Research in Singapore, involved 89 adults at risk for type 2 diabetes. Surprisingly, the study found that eating plant-based meat substitutes did not offer significant benefits to heart health over consuming animal meat. This finding challenges the common perception that plant-based substitutes are always the healthier option for heart health.

Sodium Intake and Cardiovascular Disease

Another study, presented at the American College of Cardiology’s Annual Scientific Session in April 2024, was led by experts from Piedmont Athens Regional Hospital in Athens, GA. The study analyzed data from over 3,000 participants in the National Health and Nutrition Examination Survey (NHANES). All participants suffered from cardiovascular disease. The study found that 89% of these individuals consumed more than double the American Heart Association’s recommended daily allowance of 1,500 milligrams of sodium. Excessive salt intake is known to increase the risk of hypertension and cardiovascular disease, underscoring the importance of monitoring and reducing sodium consumption.

Why Certain Foods Are Detrimental to Heart Health

Why Certain Foods Are Detrimental to Heart HealthRegardless of whether foods are plant-based or not, certain dietary components can negatively impact heart health. High sodium intake, for example, can lead to hypertension and increased cardiovascular risk. Processed and ultra-processed foods, often high in saturated fats, sugars, and salt, can contribute to the development of cardiovascular diseases.

Key Ingredients of a Heart-Healthy Diet

A heart-healthy diet typically includes:

  • Fruits and Vegetables: Rich in vitamins, minerals, and fiber, these should form a significant part of your daily diet.
  • Whole Grains: Foods like whole grain bread, brown rice, and oatmeal are excellent sources of fiber and nutrients.
  • Lean Proteins: Opt for lean meats, poultry, fish, beans, and legumes to reduce intake of unhealthy fats.
  • Healthy Fats: Include sources of unsaturated fats like olive oil, avocados, nuts, and seeds while limiting saturated and trans fats.
  • Low Sodium: Aim to stay within the recommended sodium intake to manage blood pressure and reduce cardiovascular risk.

Intermittent Fasting and Heart Health

Intermittent Fasting and Heart Health

Intermittent fasting, a dietary practice involving cycles of eating and fasting, is often promoted for its benefits such as weight loss, improved blood sugar levels, and reduced cholesterol. Some studies have shown that intermittent fasting can lower certain heart disease risk factors, such as cholesterol and blood pressure. However, recent research presented at EPI Lifestyle Scientific Sessions 2024 in Chicago suggested that eating within an 8-hour time window might increase the risk of cardiovascular death by up to 91%.

The conflicting evidence on the benefits and risks of intermittent fasting highlights the need for more long-term studies to understand its impact on cardiovascular health fully. Experts recommend that individuals considering intermittent fasting should consult healthcare professionals and consider their overall health and lifestyle.

Professor Oyinlola Oyebode from Queen Mary, University of London, emphasizes that diet is a key behavioral risk factor for noncommunicable diseases, including heart disease. Oyebode’s research focuses on understanding how diet and other lifestyle factors influence health outcomes, particularly in marginalized populations.

Ali Javaheri, MD, PhD, from the Center for Cardiovascular Research at Washington University, highlights that while intermittent fasting shows some benefits, it is not suitable for everyone. Individuals should approach such diets cautiously and seek professional advice to ensure they are safe and beneficial for their specific health needs.

The recent studies underscore the importance of dietary choices in maintaining heart health. Whether considering the impact of sodium intake, the benefits of plant-based substitutes, or the practice of intermittent fasting, it is crucial to base dietary decisions on comprehensive research and professional guidance. Adopting a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats, while limiting sodium and processed foods, remains a cornerstone of heart health.
