A whole foods, plant-based diet helps prevent heart disease risk factors, according to a study published in Nutrition. Researchers in Montreal, Canada, asked at-risk participants from a 12-week nutrition education program to increase intake of plant-based foods and tracked dietary effects on cardiovascular disease outcomes. Participants lost an average of 4.8 kg (10.5 pounds), lowered their total and LDL cholesterol levels, and reduced their waist circumferences. The authors also identified improvements in key social and psychological factors associated with a reduction in heart disease risk. This study adds to the body of evidence that vegan diets are optimal for heart health.
