PURE Study Finds High Glycemic Index Diets Linked to Cardiovascular Disease Across Ethnicities

The Prospective Urban Rural Epidemiology (PURE) study, involving 137,851 participants from 20 countries including India, has found that diets with a high glycemic index (GI) and glycemic load (GL) are associated with major cardiovascular events and deaths across all ethnicities. The findings are particularly relevant to India and South Asia, where high GI white rice or wheat forms the bulk of caloric intake, leading to very high GL diets.

Dr. Mohan, a lead researcher in the study, highlighted the significance of the results, stating, "The PURE study's findings that high glycemic index and glycemic load diets are associated with major cardiovascular events and deaths across all ethnicities are particularly relevant to India and South Asia where high GI white rice or wheat forms the bulk of calories."

Why this matters: The PURE study's findings have important implications for public health, especially in regions like India and South Asia where high GI foods are a staple part of the diet. The results emphasize the need for dietary interventions and education to reduce the risk of cardiovascular disease on a global scale.

The study suggests that replacing 'bad' high GI carbohydrates with 'good' low GI options like brown rice, legumes, fruits, and vegetables, combined with adequate physical activity, could help curb the growing incidence of premature cardiovascular disease in India. The findings extend beyond just the risk of type 2 diabetes, highlighting the broader impact of the GI and GL of diets on cardiovascular health.

Dr. Mohan emphasized the need for dietary changes, stating, "Replacing 'bad' high GI carbohydrates with 'good' low GI options like brown rice, legumes, fruits, and vegetables, combined with adequate physical activity, could help curb the growing incidence of premature cardiovascular disease in India." The PURE study's results provide valuable insights into the relationship between diet and cardiovascular health, with the potential to inform public health policies and interventions worldwide.

Key Takeaways

  • PURE study found high-GI/GL diets linked to major cardiovascular events/deaths globally.
  • Findings particularly relevant to India/S. Asia where high-GI foods dominate diets.
  • Replacing high-GI carbs with low-GI options like brown rice, legumes, fruits could help.
  • Adequate physical activity also recommended to curb cardiovascular disease risk.
  • PURE study highlights broader impact of GI/GL on cardiovascular health beyond diabetes.
