The differences between butter and margarine
The most important difference between the two is that butter is derived from dairy and is rich in saturated fats, whereas margarine is made from plant oils. It used to contain a lot of trans fats, but as mentioned above, manufacturers have now started phasing these out.
The decision of whether to choose butter or margarine depends on the specific dietary needs of the individual.
When the medical community decided that butter was not healthful due to its “bad” saturated fat content, food scientists worked to create margarine from plant oils, which they considered to be more healthful.
The margarine making process is known as hydrogenation. This process transforms liquid vegetable oil into a solid substance at room temperature. However, research eventually found that trans fats — which margarine contains — raise low-density lipoprotein (LDL), or “bad,” cholesterol levels and reduce the levels of high-density lipoprotein (HDL), or “good,” cholesterol.
Margarine therefore developed a reputation for containing a collection of harmful chemicals.
However, producers have now largely eliminated human-made trans fats from the food supply. This came after the Food and Drug Administration (FDA) ruled in 2015Trusted Source that manufacturers should phase these out of products over the following 5 years.
