Saturated Fat in the Diet
Leading Scientists Agree: Current Limits on Saturated Fats No Longer Justified - February 25, 2020
- Numerous recent meta-analyses of both controlled randomized trials and observational studies have found no significant evidence for effects of saturated fat consumption on cardiovascular or total mortality. Furthermore, there is evidence that saturated-fat intake may be associated with a lower risk of experiencing a stroke.
- Recommendations to lower saturated fat consumption have been based primarily on the evidence that this will lower LDL, the type of cholesterol in the blood that has been linked to heart disease risk. However, it is now known that there is more than one type of LDL, and that in the majority of individuals, reducing dietary saturated fat does not lower the type (small dense LDL) that is most strongly associated with heart-disease risk. This may help to explain why lowering saturated fat intake in trials has not been found to reduce cardiovascular mortality.
Dietary saturated fat intake and risk of stroke: Systematic review and dose–response meta-analysis of prospective cohort studies
- Higher dietary saturated fat intake is associated with a decreased overall risk of stroke.
- There is a linear dose–response relation between dietary saturated fat intake and the risk of stroke.
- It is necessary to re-evaluate the restrictions on saturated fat intake for future dietary guidelines.
