It doesn’t matter as much how much fat, carbs, or protein you eat—what really matters is whether the foods you eat are healthy or processed.

The study found that it doesn’t matter as much how much fat, carbs, or protein you eat — what matters more is where that fat comes from. Eating saturated fat from yogurt or fish is linked to lower heart disease risk, but from butter or red meat is linked to higher risk.

This study found that eating healthy plant foods like vegetables and whole grains lowers heart disease risk, but eating unhealthy plant foods like sugary snacks doesn’t help—even if they’re plant-based. So what you eat matters more than just how much fat, carbs, or protein you consume.

Whether you eat low-carb or low-fat, what matters most is whether your food is healthy (like veggies and whole grains) or unhealthy (like processed meats and sugary snacks)—healthy foods lower heart disease risk no matter the diet type.
