Red meat, saturated fat, and excess salt are often blamed for heart disease—the leading cause of death in the US. But according to heart surgeon Dr. Philip Ovadia, another major culprit is quietly damaging hearts every day: refined carbohydrates. These foods drive insulin resistance, trigger chronic inflammation, and contribute to the soft, unstable plaque that causes heart attacks. He sees it weekly in the operating room.
Many foods marketed as healthy are actually loaded with refined carbs. Low-fat granola, whole wheat bread, rice cakes, bagels, flavored yogurts, fruit juice, instant oatmeal, breakfast cereals, crackers, and potato chips all make the list. They may sound innocent, but they spike blood sugar, promote inflammation, and slowly wear down your cardiovascular system. The damage isn’t loud. It’s quiet. And that’s what makes it dangerous.
Dr. Ovadia recommends focusing on vegetables, healthy fats, and protein instead. The Mediterranean diet is widely considered one of the healthiest eating patterns for heart health. It emphasizes vegetables, legumes, fish, olive oil, nuts, seeds, and whole grains while limiting ultra-processed foods and excessive red meat. It’s not about cutting everything. It’s about choosing better.
Heart disease killed over 680,000 Americans in 2024. Exercise and genetics play a role, but diet remains one of the biggest lifestyle factors. You don’t have to be perfect. But swapping a bagel for eggs or a granola bar for an apple is a small change with a big return. Your heart doesn’t need perfection. It just needs less of what quietly breaks it—and more of what actually protects it.
