2017 Nutritional Fact: Saturated Fat Doesn’t Cause Heart Diseases.
For several decades, it was believed that eating saturated fat raised the risk of heart diseases. The theory was that saturated fat raised blood cholesterol levels and led to blocked arteries, which caused heart attacks.
In response to warnings from health organizations, many people replaced whole-milk dairy products with low-fat and fat-free versions. They also exchanged natural fats like butter for margarine made from vegetable oil.
However, in recent years, several systematic reviews and meta-analyses have found no connection between saturated fat intake and heart diseases.
