Which type of fats must be obtained through diet since our bodies cannot manufacture them?

Essential fatty acids are types of fats that the body cannot synthesize on its own, making it necessary to obtain them through dietary sources. There are two primary types of essential fatty acids: omega-3 and omega-6 fatty acids. These fats play crucial roles in various bodily functions, including brain health, inflammation regulation, and cellular structure.

Saturated fats, on the other hand, can be produced by the body and are generally derived from animal sources, as well as some vegetable oils. Trans fats are primarily created through industrial processes and are not essential, as they are not beneficial for the body. Cholesterol, while necessary for certain bodily functions and produced by the liver, is not classified as a fat that one must obtain from their diet.

Given this understanding, essential fatty acids are crucial components of nutrition that must be included through food sources such as fish, nuts, seeds, and certain oils to maintain health and support various physiological processes.
