The Truth about Saturated Fat | New Narrative Review



Published
A new Review proposes Saturated Fat is harmless and unfairly demonized. Does this reflect the scientific evidence? A look at the science of saturated fat, safe ranges and controversies.

Saturated fat: villain and bogeyman in cardiovascular disease?

Saturated fat is an emotional topic. Saturated fat raises cardiovascular disease if it's too high.

Saturated fat isn’t bad. Health-promoting foods have Saturated fat.

Replacing Saturated fat with refined carbs doesn't help.

Whole grains lower risk. Unsaturated fats also. PUFA, the lowest.

Source of saturated fat matters. fish has saturated fat but also PUFAs. Dark chocolate is high in Saturated fat but its stearic acid which.

we see benefit of saturated fat moderation in RCTs, usually PUFA is best. MUFA or carb, less consistent.

UK Biobank: no evidence that saturated fat intake was associated with CVD, cardiovascular disease. Replacing saturated fat with MUFA or protein was associated with lower risk of death and CVD.

Replacing saturated fat with starch was not significantly associated with CVD but was associated with lower mortality. Replacing saturated fat with PUFA was not significantly associated with mortality but was associated with a higher risk of CVD. Replacing SFA with sugar (refined carbs) was associated with lower total death but higher CVD.

PUFAs can come in fatty fish, nuts, seeds, vegetable oil, or in junk foods that contain PUFA oils. Saturated fat was associated with lower ischemic heart disease.

saturated fat replaced with PUFA benefits CVD. PUFA consumption in place of saturated fat would reduce CHD.

Linoleic acid replacing saturated fat associated with lower CHD and. Replacing saturated fat with polyunsaturated fat prevents CHD
