Study Reveals How Type 2 Diabetes Directly Alters Heart Energy and Structure

7 minutes

Type 2 diabetes directly damages your heart’s ability to make energy, leaving you more vulnerable to fatigue, swelling, and heart failure
Human heart tissue studies show that mitochondria — the power plants of your cells — lose key components in diabetic hearts, forcing the heart to beat with less fuel
Fat and sugar metabolism both become inefficient, and backup fuels fail to provide support, leaving your heart stranded without reliable energy sources
Structural changes inside the heart, including scar-like collagen buildup and weaker calcium-handling proteins, make each heartbeat less coordinated and less powerful
You can take action by cutting linoleic acid (LA) from your diet, choosing the right carbohydrates, limiting environmental toxins, using sunlight strategically, and tracking your insulin resistance with HOMA-IR to protect your heart’s energy systems
