Does Saturated Fat Raise Cholesterol and Cause Heart Disease? The Dietary Guidelines Debate

Does Saturated Fat Raise Cholesterol and Cause Heart Disease?

In this clip from my solocast on the new dietary guidelines, we break down the ongoing debate around saturated fat, cholesterol, and heart disease. For decades, saturated fat has been blamed for raising LDL cholesterol and increasing cardiovascular risk—but newer research questions whether the relationship is that simple.

We explore why some studies show saturated fat raises LDL, why other research finds no clear link to heart disease outcomes, and how factors like inflammation, metabolic health, food quality, and what replaces saturated fat in the diet all matter. This discussion also looks at how population-based guidelines are created—and where nuance often gets lost.
