Heart Disease — The world's #1 killer

Ischaemic heart disease has been the leading cause of death globally for the past two decades — and it is overwhelmingly a disease of diet. Countries with whole-food, plant-forward eating patterns consistently show 50–80% lower CVD mortality than their high-meat, high-processed-food counterparts.

The Evidence

Lyon Diet Heart Study (1999)

Mediterranean diet cut cardiac events 72% vs. the AHA control diet.
North Karelia Project (Finland)

Community-wide shift to plant oils dropped CVD mortality 80% in 25 years.
UK Biobank · Tong et al., 2019

Vegans had 22% lower CVD risk across 500,000 participants.
PREDIMED (2013)

Mediterranean diet + olive oil/nuts cut major cardiac events by 30%.
Ornish Lifestyle Trial

A WFPB diet + lifestyle reversed coronary blockages on angiography.

The Cause

Saturated fat from animal products raises LDL cholesterol. Processed meats add sodium and nitrites. Refined carbs and sugars drive insulin resistance and arterial inflammation. Plant fiber, polyphenols, and unsaturated fats do the opposite — lowering LDL, blood pressure, and inflammatory markers simultaneously.

What You Can Do

  • Eat beans, lentils or chickpeas daily — soluble fiber lowers LDL.
  • Replace red and processed meat with plant proteins.
  • Use extra-virgin olive oil as your main cooking fat.
  • Eat 5+ servings of vegetables and fruit per day.
  • Walk 30+ minutes daily — the cheapest CVD intervention.
Bottom line

"Coronary heart disease never need exist, and if it does exist, it need never progress." — Dr. Caldwell Esselstyn, Cleveland Clinic

The evidence is unambiguous: diet is the single largest modifiable risk factor for the leading killers worldwide.
