Seed Oils and Ultraprocessed Foods: One Good, One Probably Not

“Linoleic acid is the most abundant polyunsaturated fat in most people’s diets, and scientific studies consistently show that higher intake is linked to a lower risk of chronic diseases, including hearth disease, stroke and type-2 diabetes.

“And despite widespread claims online, there is no credible evidence that seed oils or linoleic acid promote inflammation in humans. In fact, research shows the opposite. Higher intake is associated with better heart health and lower risk of premature death.

“Some have raised concerns about the balance between omega-6 and omega-3 fats,” he continued. “But the idea that omega-6 intake must be reduced is not supported by current evidence. We need more omega-3 but that doesn’t mean we need to cut back on omega-6.

Replacing saturated fats like butter, lard or tallow with polyunsaturated fats from seed oils can improve cholesterol levels and reduce cardiovascular risk.
