Fatty acids are elements of fats molecules (triacylglycerols). This type of fats is current in our weight-reduction plan, however it’s additionally already current in our our bodies as physique fats. Triacylglycerols include not solely fatty acids but additionally glycerol. The fatty acids connected to glycerol may be both saturated or unsaturated, relying on the chemical bonds between carbon atoms of their chains.

Varieties of Fatty Acids

Saturated fatty acids have solely single bonds between carbon atoms. They’re principally present in animal fat (butter, lard, and the like) and unique fat (coconut, palm, and palm kernel).
Monounsaturated fatty acids have one double bond of their chains and are sometimes contained in nuts, seeds, plant oils, and avocado, amongst others.

Omega-3 fatty acids are probably the most well-known and supply the most well being advantages, together with anti-inflammatory results. These embody the important alpha-linolenic acid (ALA), which we have to get hold of from our weight-reduction plan as a result of our our bodies can not produce it on their very own. Moreover, omega-3 consists of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), that are derived from ALA however solely in small portions (about 5% is transformed to EPA and fewer than 0.5% to DHA). Subsequently, we should additionally purchase them from meals sources. [8]
Omega-6 fatty acids additionally embody a necessary fatty acid referred to as linoleic acid, which is transformed within the physique to arachidonic acid. Omega-6 fatty acids, like omega-3s, have partly anti-inflammatory results but additionally contribute to the manufacturing of pro-inflammatory substances.
