Doubling saturated fat in diet does not increase saturated fat in blood

New research links diabetes, heart disease risk to diet high in carbohydrate — not fat.

Doubling or even nearly tripling saturated fat in the diet does not drive up total levels of saturated fat in the blood, according to a controlled diet study. However, increasing levels of carbohydrates in the diet during the study promoted a steady increase in the blood of a fatty acid linked to an elevated risk for diabetes and heart disease.

The finding “challenges the conventional wisdom that has demonized saturated fat and extends our knowledge of why dietary saturated fat doesn’t correlate with disease,” said senior author Jeff Volek, a professor of human sciences at The Ohio State University.

“When you consume a very low-carb diet your body preferentially burns saturated fat,” Volek said. “We had people eat 2 times more saturated fat than they had been eating before entering the study, yet when we measured saturated fat in their blood, it went down in the majority of people. Other traditional risk markers improved, as well.”

Obesity rates from 1975 to 2014

Hover your mouse over a country to see how much the population’s obesity has increased from 1975 to 2014. The figures are from a study published in The Lancet where researchers compiled data from 1,698 obesity-related studies on 19.2 million people in 186 countries.
